Re: Got an interview, need some idea for projects.

[Jack Lin]

Hi Motaz, Aditya, and all.

Won’t that be too easy? Thinking of something more complex like something
need to include a scraper.
But I’m not sure if that can be done In a week.

I think I will like to find a complex stocks article. No need to base on
programming, maybe just a simple theory that I can simulate I python and
put that an a website. What do you guys think?

I got a few knowledge and a lot of interest in stock. But I got no ideas

Re: DjangoEveryDay. My practice website!

My Major is information and communication. Kind of Mass Communication but
we made our content more specific to internet world.
I’m not really sure what you mean in
“and importantly how you think contributes to a certain type — or even
workflow or stack — of learning in CS. “
"tying in what you know, how you behave," You mean like do some projects
for my own area?

Re: DjangoEveryDay. My practice website!

Actually DjangoEveryDay and Jack's Practice Zone is the same thing.
It is something like “Practice Django Every Day in Jack’s Practice Zone”
But the different name seems confuse. I’ll fix it.

Re: How to create form to show user input and return results from DB

[victor jack]

Hi Nina , just read your write up 
For some form of clarification to your Confusion I’ll just answer the ones I 
can 

For the database , don’t make two different ones , one database with two tables 
2000 and 2010 will do just fine , just query then right. 

For the forms it is required to use POST cause it is more secure since you are 
POSTING form data ( which I feel is sensitive information)

I hope this helps , if I am free I might check out your github link

Greeting, introduce myself & wondering if one read all documentation.

[Jack Lin]

Hi all. I'm a new self-taught developer. Just decided to make backend 
development especially Django to be my full time career. 
I'm new to programming.. at least i just create my own ugly website and 
never involve in big projects or open-sources. I read a lot of tutorial and 
got the basic ideas through year but i didn't really acquire the ability of 
programming. I think I just don't spend enough time and always switching 
from field to field. I learn RoR, python, C, Unity, Security yeah, I 
know. too much and too naive. 

I know my passion is to create tools that utilize life and analyzing. 
ok, enough self introducing. 


I'm going through   
from 37 signals recently and starting to read Django's documentation.
The details in the documentation makes me exciting and happy. so i think 
i'm okay to read through it all.
However, I'll like some share of experience which is any one go through the 
whole documentation before?
does it change you or improve your skills in significant way? not limited 
in Django. if anyone used to read all the basic and have some thought, may 
you share that with me :)?

Serving non-referenced static files

[Jack Sundberg]

Hello again, 

I could use some help on loading static files in development mode. 
Specifically, I'd like to tell Django to serve additional files that are 
not explicitly loaded in the html with {% load static %}. My issue is 
actually identical to this post 
<https://groups.google.com/forum/#!searchin/django-users/js$20files%7Csort:date/django-users/FEO0gy37dRw/WeU8GdK4DAAJ>,
 
where I could use some extra explanation on their suggested fix. To restate 
the issue, I load a static javascript file within my myapp/index.html:

{% load static %}
 

The javascript file (myscript_1.js) references another javascript file 
(myscript_2.js) as well as some other media (e.g. a number of *.png, *.css, 
*.json files). However, Django doesn't serve these files because they are 
not directly loaded in the html, and a 404 error is thrown when trying to 
find myscript_2.js - along with the other files. How do I get Django to 
serve these files as well? 

It looks like Django is searching for the files 
at http://127.0.0.1:8000/myapp/myscript_2.js. Could I forward this path to 
http://127.0.0.1:8000/static/myapp/myscript_2.js? I'm trying to do this 
with the following in my urls.py (in projects urls.py - not the myapp 
urls.py):

from django.conf import settings
from django.conf.urls.static import static
urlpatterns += static(path=settings.STATIC_URL, document_root=settings.
STATIC_ROOT)

and in my settings.py:

STATIC_ROOT =  os.path.join(BASE_DIR, 'static')
STATIC_URL = /static/

This isn't working for me though, and I think I'm using the static() 
function incorrectly. Could someone offer some guidance on how to set this 
up for development testing?

Thanks in advance,
Jack

Thank you, James! This seems like a good fix. From reading through the

Is that the best way to do it?

Re: Creating an app that generates static files

[Jack Sundberg]

Yes, I tried getting the idea across in layman terms, as I hope this helps 
discussion of the issue -- and then I can later translate the solution into 
django implementation. 

I avoided the full process in my original post for clarity. I used the 
*.jpeg file as an illustrative example, when I'm actually generating *.gltf 
and *.bin files. These files are typically a couple hundred KB in size, but 
I will have thousands of them (millions as I add to my database). These 
files are used in coordination with Verge3D  - an app built on top of 
Three.js for 3D rendering. Verge3D allows use of Blender for CAD, which is 
a python-based program that my scripts are written in. Running of these 
scripts are certainly cpu intensive; however I am going to get around this 
by using an  of this Verge3D request.

So to be more specific, my app does the following:
 - the url mapping pulls a database entry
 - the app serves the proper html template with an  embedded in it. 
It displays a loading screen while the 3D model is created backend.
 - the  calls a separate app using the identical data entry
 - using the data entry, static files are created from the data (Blender 
script creates a *.gltf and *.bin)
 - the app serves the html template with the generated static files 
embedded inside the 

Is this helpful? Also thank you for the quick response. I really appreciate 
the help.

Creating an app that generates static files

[Jack Sundberg]

Hi all,

I am currently writing an app that generates static files before serving 
them, and I could use some input! Here's a step-by-step example of how the 
app is setup:

 - the url mapping pulls a database entry
 - using the data entry, static files are created from the data (for 
example, a *.jpeg or a *.gltf)
 - the app serves the html template with the generated static files 
embedded (for example, via an  tag)

The issue comes with the creation of the unique static files. I can have 
the app create a file in the static folder, send it off, then delete the 
file to ready for the next request -- but the webpage will run into issues 
if multiple requests are made at the same time. If two people request the 
same url at the same time, the app will fail because both requests are 
trying to create/serve/delete an identical file (i.e. entry123.jpeg) at the 
same time. Trying to mess with the filename to avoid this won't work here 
either (i.e. naming entry123.01.jpeg, entry123.02.jpeg, entry123.03.jpeg, 
...).

I can think of two solutions, but they both are things I'd like to avoid:
 1. have the files premade and stored -- I want to avoid this because of 
the massive filesize required for all these files
 2. have the static files generated in a user-specific directory -- I want 
to avoid this because I'd rather not have registered users on my website

Is there another solution to this? I'm still relatively new with Django, so 
there might be something simple I'm missing.

-Jack

I need adding records within another model

[Jack Gonzales]

Hi everyone, i have two classes in my model.py, this system is for 
registering the payments of an account, for instance, a client is lent 1000 
dollars and that account has an ID, each loan has an ID and what i want is 
when the client makes the payment of his fees i can register each ammount 
and that every payment is linked with the ID of the account, 1000 dollars 
could be 10 payments of 100 dollars and that 10 records are linked to that 
account and the same for all loans, every loan with its records of payment. 
I hope that you've could understand and help me.
 

## THIS IS THE MODEL OF LOANS DATA WHERE THE DATA OF LOAN IS STORED.

class LoansData(models.Model):
"""
Profile model.

Proxy model that extend the base data
with other informarion.
"""

customer   = models.ForeignKey(CustomerData, 
on_delete=models.CASCADE)
ammount= models.PositiveIntegerField(default=0)
interest   = models.DecimalField(max_digits=3, decimal_places=2)
total  = models.PositiveIntegerField(editable=False)

uid   = models.CharField('UUID', max_length=5, help_text='5 
characters', blank=True)

created= models.DateField(auto_now_add=True)
modified   = models.DateTimeField(auto_now=True)

def save(self, *args, **kwargs):
self.total = self.ammount + (self.ammount*self.interest)
super(LoansData, self).save(*args, **kwargs)



class Meta:
verbose_name = 'Loan Data'
verbose_name_plural = 'Loans Data'

def __str__(self):
""" Return username """

return str(self.pk)   






#THIS IS WHAT I CREATED FOR ADDING THE RECORDS OF EVERY PAYMENT THE CLIENT 
MAKES TO ITS RESPECTIVE ACCOUNT OF LOAN. BUT IF IT'S NECESSARY CHANGE THIS IT 
DOESN'T MATTER.


class LoanInstance(models.Model):

"""
This represents the status up to date of loan
"""

Converting GeometryField to MultiPolygon using GeoDjango?

[Jack]

I am trying to add a bunch of school boundary files into the database.  The 
boundary files are inconsistent.  They are processed by `DataSource` as 
either `Polygon`, `MultiPolygon`, or `GeometryCollection`.

Converting `Polygon` into `MultiPolygon` is fairly simple using this 
solution 
(https://gis.stackexchange.com/questions/13498),
 
but the conversion does not work for `GeometryCollection`.

class School(models.Model):
boundaries = models.MultiPolygonField()

---

from django.contrib.gis.geos import Polygon, MultiPolygon
from django.contrib.gis.geos.collections import GeometryCollection

ds = DataSource('school_boundaries.aspx')
feature = ds[0][0]
geom_geos = feature.geom.geos
if isinstance(geom_geos, Polygon):
geom_geos = MultiPolygon(geom_geos)
elif isinstance(geom_geos, GeometryCollection):
geom_geos = MultiPolygon(GeometryCollection)  #This does not work
school = School(boundaries = geom_geos)
school.save()

Is there some way to convert `GeometryField` to `MultiPolygon` in GeoDjango?

removed the interpreter and add it again because i thought it was the 
problem but the problem continues, i've uninstalled pydev from eclipse and 
the problem is the same.

If someone knows about this, please help me.

Thnks a lot.

Single-page app with dynamic filtering - 2 options to proceed

[Jack]

I am building a real estate listings map, which dynamically refreshes its 
filter whenever the user moves the map. The page never refreshes when a 
change is made. Think Zillow/Trulia 

.

There are 2 main filters:

   - Filter properties within the user's viewport
   - Filter properties according to user's custom filter (e.g. property 
   type, # of bedrooms, etc.)

I see 2 methods of approaching this problem.

   1. 
   
   On initial visit, pass ALL properties in the database to the user. And 
   then filter these properties whenever the user moves his map or changes his 
   filter selection.
   2. 
   
   Create an ajax call whenever the user moves his map or changes his 
   filter selection. The ajax call will only return the properties that match 
   the user's current requirements.
   
Which method is preferable? I estimate there will be maybe 200k-300k 
records in my database.

Django - Paginate with another GET request; not working with just pagination page number

[Jack]

I'm building a page with pagination and a filter form (2 GET requests).  If 
the URL includes both pagination and filter results, something like 
`/questions/?page=2_questions=on`, it works fine.  It also works if it 
just has filter results, something like `/questions/?all_questions=on`.

However if it only has the pagination page result, something like 
`/questions/?page=1`, no results are shown.

So I figured I need to do something in the views so that if there is only 
page number in the URL, a default filter will be given.  I know I probably 
need to add something to the Try and Except section of pagination, but I'm 
stumped as the actual code I need to write.


def questions_index(request):

user = request.user
form = QuestionFilterForm(request.GET or None)
question_list = []
if not form.is_bound:
question_list = Question.objects.all().order_by('-date_created')
if form.is_valid():
if form.cleaned_data['all_questions'] | 
(form.cleaned_data['general_questions'] & 
form.cleaned_data['location_all_gta']) == True:
question_list = 
Question.objects.all().order_by('-date_created')
elif form.cleaned_data['location_all_gta'] == True:
question_list += 
Question.objects.filter(question_type=1).order_by('-date_created')
else:
if form.cleaned_data['general_questions'] == True:
question_list += 
Question.objects.filter(question_type=2).order_by('-date_created')
if form.cleaned_data['location_toronto'] == True:
question_list += 
Question.objects.filter(location='1').order_by('-date_created')

paginator = Paginator(question_list, 15)

# Pagination
page = request.GET.get('page')
try:
questions = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
questions = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. ), deliver last page of 
results.
questions = paginator.page(paginator.num_pages)

### I need to write something here...
except (url has no filter result)  
give default filter 

return render(request, 'questions_index.html', {'questions': 
questions, 'user': user, 'form': form})

Re: Seeking design guidance on a Team model where a user sends invitation to other users to join the team

[Jack]

Hey Adam.  I took a week to properly learn some JavaScript and jQuery and 
how to make ajax calls.  I just got it working!  It was much simpler than I 
thought.  I created a views to catch the appropriate agent's pk and put 
that in a data-href attribute like this:

Send Invite

Then I passed the button into an ajax call... a few lines of processing in 
the `send_invitation` views and it works nicely.  Took maybe 15 lines of 
code in total?

Thanks for your help, but mainly thanks for leading me into using ajax.  I 
was always too lazy to properly learn javascript but now, I can do a lot 
more with jquery and ajax!

Best regards,

Re: Django - Pass a model instance specified by template tags to the view

[Jack]

Ok I'm very stuck.  Thought very hard about it but can't see how I can add 
a hidden field into the HTML, and relay the specified instance of the 
hidden field back to the views... or am I completely off about something?

Also in regards to the looped form's.  If you look at my original code, I 
actually do have a  representing a button for each agent.  The 
resulting page looks like this 
 (excuse the bad 
CSS).  I'm not sure if that is what you meant by having a form for each 
agent.

So if I understood you correctly, I do have a separate  input for 
each displayed agent; looped with {% for agent in agent_list %}.  The 
question is, how do I relay the correct agent linked to its 'Send Invite' 
button back to the views?

Re: Django - Pass a model instance specified by template tags to the view

[Jack]

There will be a lot of agents in the database, so would it violate the DRY 
principle if I were to write a form for each agent?  Plus it'll be super 
time consuming.

I'm going to try the hidden agent.id thing, I never thought about that.  
I'll report back to see if I managed to get it working.

Django - Pass a model instance specified by template tags to the view

[Jack]

On my HTML page, I have a list of Agent's (Agent is my custom User model).  
Beside each agent is a 'Send Invite' button.  To create a `TeamInvitation`, 
I need to specify which Agent is attached to its `receiver_agent` field (a 
OneToOneField with Agent)

There are multiple Agents displayed on the HTML page, and they are listed 
in order with template tags.  I need to input something after `pk` at 
`receiver_agent = Agent.objects.get(pk = ???)`, but I don't know what to 
input.

*views.py*

class InviteAgentSearchResults(ListView):
model = Agent
form_class = AgentSearchForm
template_name = 'invite_agent_search_results.html'

def get_queryset(self):
# ... Code to find correct list of agents

def post(self, request, *args, **kwargs):
invite = TeamInvitation.objects.create(receiver_agent = 
Agent.objects.get(pk = ???))
return HttpResponse('Invite successfully sent.')

*HTML:*

{% for agent in agent_list %}

# ... Some code here

  # The "Send Invite" button
{% csrf_token %}
Send Invite


{% endfor %}

Re: Seeking design guidance on a Team model where a user sends invitation to other users to join the team

Stupid question as I've never used a 3rd party app before...  Am I supposed 
to download the source code and put that into my project folder?  I already 
did 'pip install django-invitations'.

Seeking design guidance on a Team model where a user sends invitation to other users to join the team

[Jack]

I have a model called *Team*, which has a ForeignKey relationship with 
*User* (a team can have many users, but a user can only be part of one 
team).

A user can create a team, and that user will automatically become a *Team 
Leader* (a group, not a model).  The team leader can query the database for 
other users and send invitations to other users join his team.  Users who 
receive an invitation can either accept or decline the invitation; if a 
user accepts an invitation, he joins the team as as a *Team Member*

My question is, how do I go about designing the invitation system?  After 
the team leader clicks the 'Send Invitation' button, the receiving-user 
should see a special invitation message on his dashboard, which he can 
either accept or decline.

My current thinking tells me I should create a model called *Invitation* 
which has a OneToOne relationship with User.  When an invitation is sent, 
an instance of Invitation is created which is assigned to the 
receiving-user.  The invitation instance will be deleted when the 
receiving-user accepts or declines the invitation.

Another method I can think of is to send an Email to the receiving-user.  
The Email will be like an account activation Email, except the activation 
link adds the receiving-user to the team and marks the receiving-user as a 
*team 
member.*

Pointers and guidance welcome.  I feel like both my methods are clumsy and 
maybe there is a built-in feature in Django which I missed which could 
solve this problem much easier.

MultipleChoiceField is being displayed as a string instead of a list

[Jack]

I have a MultipleChoiceField forms field which shows up in the database like 
this . It seems to have been converted 
to a string in the database, because when I try to display it with a 'for 
property in property_type' statement in the HTML, it shows up like this 
. I want it to be displayed like this 
.  I have also tried using an 
ArrayField (shown below), but the result is the same.


models.py:

property_type = models.CharField(max_length=50, help_text="You can select more 
than 1 option")

property_type = ArrayField(models.CharField(max_length=50), help_text="You can 
select more than 1 option"))


forms.py:

property_type = forms.MultipleChoiceField(widget=forms.SelectMultiple, 
choices=BuyerListing.PROPERTY_TYPE)

HTML:

{% for property in listing.property_type %}
Property type: {{ property }}
{% endfor %}



How do I get this MultipleChoiceField to load as a list so I can display it 
properly with a for statement?

Re: Building a search form with 4 required choices, which will be inserted as arguments in an URL [warning: long question]

[Jack]

That makes much more sense.  It's my fault for not reading the Django docs 
properly, but I don't seem to soak in the concepts at all by simply 
reading.  

I went with a ListView + get_queryset override.  I haven't managed to get 
the filter to work but the search itself is working properly.

Thanks Daniel!

Re: Passing 3 user inputs as argument in url, for a search form

[Jack]

I managed to get the code functional.  I haven't done extensive testing but 
it's certainly working right now with your code plus some of my own fixes.  
I should read the documentation more carefully in the future.

Thanks again for the super detailed response James.

MultipleChoiceField records down choices as a list, but CharField converts them to a list?

[Jack]

I have a model field for choosing multiple options.  Here is the code for 
models and forms:

*models.py:*
CONDO_APARTMENT = 'Condo Apartment'
DETACHED_HOUSE = 'Detached House'
SEMI_DETACHED = 'Semi-detached'
TOWNHOUSE = 'Townhouse'

PROPERTY_TYPE = (
(CONDO_APARTMENT, 'Condo Apartment'),
(DETACHED_HOUSE, 'Detached House'),
(SEMI_DETACHED, 'Semi-detached'),
(TOWNHOUSE, 'Townhouse'),
)

property_type = models.CharField(max_length=50, help_text="You can 
select more than 1 option")


*forms.py:*
property_type = forms.MultipleChoiceField(widget=forms.SelectMultiple, 
choices=BuyerListing.PROPERTY_TYPE)


Let's assume the selected choices were 'Condo Apartment' and 
'Semi-detached'.  The value stored on my database is this - ['Condo 
Apartment', 'Semi-detached']

Now this is in a list format, which makes sense, but it seems to have been 
converted to a string.  When I try to call on property_type in a .html 
document...

{% for property in model.property_type %}
{{ property }}
{% endfor %}

The result is displayed in singular characters, like this:

[
'
C
o
n
d
o
 
a
p
.. and so on.  Instead I want the result to be the values in the list, like 
this:

Condo apartment
Semi-detached

How do I do this?  I tried experimenting with different model field types 
but CharField seems like the only appropriate one for MultipleChoiceField.

Passing 3 user inputs as argument in url, for a search form

[Jack]

I am building a search form where the user inputs 3 values on a form, and I 
search the database for all records that match the 3 inputs.  Right now I 
am stuck on the user input part.

If you look at my *urls.py*, you will see that I tried to put 3 keywords 
arguments in there.  Then I tried to pass the 3 keyword arguments in the 
url tag with variables from my *forms.py*.  I think this is where things 
went wrong but I'm not sure.  I don't know if the .html file can use 
variables from *forms.py*

Basically what I'm trying to do is to take the 3 user inputs, and pass them 
as arguments in the URL.  Right now I'm getting:

NoReverseMatch at /

Reverse for 'search-results' with keyword arguments '{'pt': '', 'nb': '', 'nw': 
''}' not found. 1 pattern(s) tried: 
['search?(?P\\w+)&(?P\\w+)&(?P\\w+)']



*urls.py*
url(r'^search?(?P\w+)&(?P\w+)&(?P\w+)', 
views.IndexSearchResults.as_view(), name='search-results')


*index.html *

{{ form.as_p }}



*views.py*
class IndexSearchResults(generic.ListView):
template_name = 'search-results.html'


*models.py*
Class BuyerListing(models.Model):
 BEDS_OPTION = (
(BEDS_0, '0 [Studio/Bachelor]'),
(BEDS_1, '1'),
(BEDS_1_1, '1+1'),
(BEDS_2, '2'),
(BEDS_2_1, '2+1'),
(BEDS_3, '3'),
(BEDS_3_1, '3+1'),
(BEDS_4, '4'),

(WASH_3, '3'),  
(WASH_4, '4'),  
(WASH_5, '5'),  
(WASH_5_1, '5+'),  
)

PROPERTY_TYPE = (
(CONDO_APARTMENT, 'Condo Apartment'),
(DETACHED_HOUSE, 'Detached House'),
(SEMI_DETACHED, 'Semi-detached'),
(TOWNHOUSE, 'Townhouse'),
)

property_type = models.CharField(max_length=50)
number_of_bedrooms = models.CharField(max_length=50, default=BEDS_0)
number_of_washrooms = models.CharField(max_length=50, default=WASH_1)


*forms.py*
class MainSearch(forms.Form):

property_type = forms.ChoiceField(choices=BuyerListing.PROPERTY_TYPE)

number_of_bedrooms = forms.ChoiceField(choices=BuyerListing.BEDS_OPTION)

number_of_washrooms =

Re: Automatically assign model instance to the user who created it. And only that user can edit/delete the instance.

[Jack]

I tried using FormView but kept running into errors.  I used your second 
response and it worked!  I don't fully understand the code, but it seems to 
work flawlessly.

Thank you so much! I own you a big one.

Re: Automatically assign model instance to the user who created it. And only that user can edit/delete the instance.

[Jack Zhang]

Thanks for your response.  This is an off-topic question but I can't figure 
out how to get 'request' working.  I'm using the CreateView generic class, 
so there's no space to insert 'request'.  This is what my code looks like.  
When I try to run it, it tells me that request is not found.  

class ListingCreateView(LoginRequiredMixin, CreateView):
model = BuyerListing

form_class = PostListing(self.request.POST)
if form.is_valid():
form_save = form.save(commit=False)
form_save.user = request.user # user is logged in
form.save()

def get_queryset(self):  # the user want to edit this post must be 
owner this post
post_qs = super(PostListing, self).get_queryset()
return post_qs.filter(user=self.request.user)

Automatically assign model instance to the user who created it. And only that user can edit/delete the instance.

[Jack Zhang]

Let's say I have a model called 'Dogs'.  Users can create instances of 
Dogs.  Let's say we have a user called User1.  I have 2 questions:

1. When User1 creates an instance of Dogs, how do I automatically assign 
that instance to User1?  I tried using a model field like this but it 
doesn't pick the user automatically:

user = models.ForeignKey(User, unique=False)

2. After the instance has been created, how do I make the instance only 
editable and removable by the user who made it?  Basically, if User1 
creates an instance of Dogs, only User1 can edit and delete that instance. 

Thanks.

Re: Generating a unique 10 digit ID for each model instance

[Jack Zhang]

Hi James,

First of all thank you for all your detailed replies.  You have a wealth of 
knowledge.  

I took your advice and chose the separated method.  I decided to use 2 
letters + 8 numbers because 3 letters can render results like 'SEX' and 
'FUK'.

I think I got it right.  Here is my code:

class Dogs(models.Model):

def random_number():
a = random.randint(1000, )
b = Model.objects.values_list('id_numbers')
for num in b:
if a == b:
a = random.randint(1000, )
return a

def random_letter():
import string
a = ''
for i in range(2):
a += random.choice(string.ascii_uppercase)
return a

id_numbers = models.IntegerField(default = random_number)
id_letters = models.CharField(max_length=2, default = random_letter)

Building a search form with 4 required choices, which will be inserted as arguments in an URL [warning: long question]

[Jack Zhang]

This is a semi-long question.  Please let me know wherever I make a mistake.

I'm building a search form with 4 required choices, 1 of the choices is a 
CharField with a max_length of 3.  The other 3 choices are ChoiceField's.  
Here is a picture of what the search form looks like:



I've read through the Django docs and other things on the Internet but I'm 
still very unclear about how to approach this.

1. First I believe I need to create 4 args or kwargs in the url for each of 
the choices.  If I use args, it would look something like...

url(r'^search?(\w+{3})&(\w+{2})&(\w+{1-2})&(\w+{1-2})', function/class 
view, name='search')

2. Next, I need to pass the user's input in the html page into the url 
args.  I have a form set up to get the user's input.  But how would I write 
this on the HTML page?  Do I simply make a url tag like {% url 'search' 
args1, args2, args3, args4 %}?

3. Then I need to create the views function.  My first question is, should 
I use a function-based view or the generic class-based ListView?  The 
result of the search will be a list of items, so ListView is a good 
template to use, but I don't know how having 4 args would affect using 
ListView.  My second question is, what is the most effective way of making 
this search?  I need to check if any records in the database matches the 
user's search, so would I do something like 'For record in database' to 
check over every record in the database?

If I used a function view, would it look something like:

def search(request, args1, args2, args3, args4):
 for record in database:
  if args matches record:
   display record

Thank you for reading through the question

Re: Generating a unique 10 digit ID for each model instance

[Jack Zhang]

I need this 10-digit unique ID for every model instance so users can easily 
search up a specific model instance.  It will be publicly displayed on the 
website, unlike a primary key which is usually hidden

Re: Generating a unique 10 digit ID for each model instance

[Jack Zhang]

Hi Andréas,

Yes, by globally unique I mean a unique 10-digit ID is assigned to every 
model instance of 'Dogs' within my application.  This ID will be shown 
publicly on the website to allow easy search access to a specific model 
instance.

I think you are right about creating a new field to hold the unique ID, 
instead of using the primary key.  Generating the ID is not too difficult, 
but how can I ensure that I won't generate a duplicate ID?  From briefly 
thinking about it, this is what I got...

When a new instance is created, generate *new ID*
For every *existing ID* in the database:
 If *new ID* == *existing ID* in the database:
  Generate *new ID* and re-run the for loop
If *new ID* does not match any *existing ID * in the database, proceed with 
continuing the model instance.

Also I read up on Signals, but is it necessary?

Generating a unique 10 digit ID for each model instance

[Jack Zhang]

Let's say I have a model called 'Dogs'.  Users can create instances of 
Dogs.  For every Dogs instance that is created, I want to assign a globally 
unique ID to it.  The ID will be 3 capitalized letters followed by 7 
numbers.  E.g. ABC1234567, POZ2930193

What is the easiest way to go about doing this?  I looked into UUID but it 
generates a longer string.  Keep in mind that the ID must be globally 
unique - so after one has been created, it should not be created again.

Thanks.

Django 1.11 - Best Datepicker to use?

[Jack Zhang]

I'm looking for a datepicker widget to use for a DateTime form field.  I 
searched around and most of the answers were old Stack Overflow posts from 
2011 about hacking the calendar datepicker widget from Django's Admin.  The 
information about that was inconclusive and I couldn't get mine to work.

As of right now, what is the best Datepicker I can use for a DateTime form 
field?  It doesn't have to be Django's Admin, or anything fancy.  It just 
has to be perfectly functional.

Getting my head around ForeignKey, One-To-Many and Many-To-Many.

[Jack Razors]

I am creating a mindmap visio-like editor website using d3js and a bunch of 
custom javascript.  Rather than the schema/stencils being populated by 
static JSON files, I wanted to create an administration area to edit the 
schema without requiring JSON kung-fu skills and serve the dynamically 
generated JSON to my javascript app on the fly.  

I have 2 models that I am trying to figure out the best way to create a 
relationship between.

class EditorVocab(models.Model):
VOCAB_TYPES = (
('string', 'String'),
('textarea', 'Text Box'),
('list', 'List of values'),
('list-identifier', 'Open Vocabulary/Dictionary'),
('object_ref', 'Object Reference'),
)

vocab_name = models.CharField(max_length=255, unique=False, 
blank=False, null=False)
label = models.CharField(max_length=255, unique=False, blank=False, 
null=False)
help_text = models.CharField(max_length=255, unique=False, blank=True, 
null=True)
default_value = JSONField(default={}, blank=True, db_index=True)
vocab_type = models.CharField(max_length=255, choices=VOCAB_TYPES, 
unique=False, blank=False, null=False)

class Meta:
managed = True
db_table = 'editor_vocabularies'

def __str__(self):
return '%s (%s)' % (self.label, self.vocab_type)


class EditorStencil(models.Model):
stencil_type = models.CharField(max_length=32, unique=True)
stencil_name = models.CharField(max_length=128, unique=False)
stencil_icon = models.FileField(upload_to='stencils')
schema = models.ForeignKey(EditorSchema, on_delete=models.CASCADE)
vocab = models.ManyToManyField(EditorVocab, related_name="vocabs")
vocab_requirement = models.ManyToManyField(EditorVocab, 
related_name="required_vocabs", blank=True)

class Meta:
managed = True
db_table = 'editor_stencil'

def __str__(self):
return '%s (%s)' % (self.stencil_name, self.stencil_name)

I am using Postgres with the jsoneditor integrated into the Django Admin 
area and it works well.  What I would like to have is a One-to-Many 
relationship from EditorStencils -> EditorVocab and be able to 
select/edit/add which "vocabs" are apart of a stencil as well as required. 
 This works with ManyToManyFields but a vocab needs to belong to a stencil. 
 The way it is now, it could potentially belong to multiple stencils (which 
I do not want).

Thanks in advance!

Re: Need help modifying form on intermediate page of admin action

[Jack Twilley]

I looked over those apps and I don't think they'll help with my issue.

Let's say that Crate 1 has a capacity of 12 and currently holds 10 jars. 
 If I look at the jars in Crate 2, select 3 of them, and then trigger the 
admin action to move the selected jars, Crate 1 should *not* be in the drop 
down list on the intermediate form because it only has room for 2 more 
jars.  There isn't really a value entered by the user, it's just the number 
of jars that are selected before the admin action is triggered that matters.

I do not know how to modify the value of dest in an unbound instance of 
MoveMultipleJarsForm based on the length of the queryset.  As a workaround, 
I think I could do some validation in move_multiple_jars() that would check 
the capacity of the destination and generate an error message if the 
destination can't hold all the selected jars, but that seems inelegant.

Jack.

Transform all Django exceptions to JSON?

[jack]

Hello, 

I use django rest framework to make API server. DRF catches some Django 
exceptions and transforms them in JSON. However some exceptions, like 404, 
are still returned as Django pages (at least it works that way on my 
machine). How can I wrap all exceptions in JSON from any library? I'm 
working on mobile app and I can't debug html dumps from Django in console 
:( 

Am I missing something important?

django 1.7 migration generates wrong column name for foreign key to a one-to-one model

[Jack Peng]

I ran into this problem trying to run manage.py test. The error I get looks 
like this:


ALTER TABLE "quote_agentorderrejection" ADD CONSTRAINT 
"quote_agentor_agent_id_1388a6f8215473de_fk_user_agentprofile_id" FOREIGN 
KEY ("agent_id") REFERENCES "user_agentprofile" ("id") DEFERRABLE INITIALLY 
DEFERRED
Traceback (most recent call last):
File 
"/home/jack/Envs/envp1/lib/python3.4/site-packages/django/db/backends/utils.py",
 
line 66, in execute
return self.cursor.execute(sql, params)
psycopg2.ProgrammingError: column "id" referenced in foreign key constraint 
does not exist


I realize this is similar to https://code.djangoproject.com/ticket/23415, 
which has been fixed. However, my case is a little different.


class AgentOrderRejection(models.Model):
agent = models.ForeignKey(AgentProfile)

But AgentProfile itself is a one-to-one model to the user model, so its 
primary key is user_id, not id.

user = models.OneToOneField(USER_MODEL, primary_key=True)

But django 1.7's migration incorrectly identifies id as the primary key and 
looks for it in the agentprofile model and fails. Does anyone have similar 
experiences? Thanks.

Jack

Doing a relationship lookup from within a model.

[Jack Morgan]

I've got 2 tables that are related to each other. Orders and History.
Inside the History table is the 'status' column. Like so..

class Orders(models.Model):
  'order info'

class History(models.Model):
timestamp = models.DateTimeField(auto_add_now = True)
order = models.ForeignKey(Orders)
user = models.ForeignKey(User)
comment = models.TextField()
status = models.CharField(max_length = 20)


I'm storing the status in the History table right now because I need to keep
track of who is moving the orders along.  However, I need to do a lookup on
orders based on their current(most recent) status.  For simplicities purpose
it seems a good idea would be to just put a status field in the Orders table
and update as the Order advances through the stages. However, that creates
duplicate data, which my client has expressed an extreme hatred for.

What It's like to be able to do is something like:
o = Orders.filter(status = 'new')

I'm not entirely sure how or when relationship managers are brought in, so I
was thinking something like this in the Orders model:
status = self.history_set.values('status').order_by('-id')[0]['status']

But that wouldn't let me do a lookup by state.

What's a good Django way to handle this issue?

Thanks!

Hey gang,
I am trying to use a response object to serve a dynamically created CSV. I have 
that part working perfectly but I'd like to display a page afterwards with a

template to the httpresponse object after I write the CSV into it but it gives 
a header error.

Re: Getting a count of a RawQuerySet object

[Jack Morgan]

Hi, thanks!
The issue I'm getting here is that the RawQuerySet object does not have the
.count() method so it just gives an error.
I also just checked that it does not have the 'all()' method either.

Getting a count of a RawQuerySet object

[Jack]

Hello everyone, I'm quite new to django and python in general so I'm
sure there's just something I missed in my searching to answer this.
But...

Is there a way to count the number of results returned in the
RawQuerySet option?

I've tried the len() function and I've search the django documentation
with no results. So, any help would be very welcomed.

Thanks!

I don't use the django ORM, but running the postgres command 'set  
search_path = some_schema,public' works for me. This sets the schema  
search path only for the connection on which the command is run.

Serving static content

[Jack Orenstein]

I have my first Django app running, but with very basic html. I'm  
trying to add my first  tag and finding it difficult to serve up  
the image file.

I've read this: http://docs.djangoproject.com/en/dev/howto/static- 
files/?from=olddocs, which points out that having django serve static  
content is "inefficient and insecure", and then points to a reference  
for Apache plus mod_python.

Questions:

1) The method outlined above isn't working for me. urls.py says (for  
my foobar application):

 (r'^media/(?P.*)$', 'django.views.static.serve',   
{'document_root': '/Users/jao/django/foobar/media'}),

/Users/jao/django/foobar/media/images has xyz.gif, and my page says:

 

But when I load the page, the image doesn't show up. I get a little  
box with a question mark in it.


2) I'm not using mod_python, I'm using mod_wsgi. Is the procedure  
pretty close to that of mod_python?


3) Why exactly is the builtin django method insecure?


Thanks for any help.

Thanks, that's really useful to know about. This works for most of  
the additional validation I need to do, but doesn't fit so well for  
the cross-field validation, (e.g. password and confirm_password  
fields match). Or can I do that by overriding Form.is_valid?

validation of Fields done by django. So in my form handler, I check  
Form.is_valid, and if that returns true, then I do my own validation.  
In case of errors, I attach an error message to the field, e.g.

 self.form.fields['foobar'].errors = 'some error message'

And then I redisplay the form. But the error message doesn't show up,  
even though the template includes

 {{ form.foobar.errors }}

And through logging I have confirmed that the errors attribute of the  
field has been set, right before the render_to_response call  
containing the form. I'm guessing that this has something to do with  
the fact that the form already passed the is_valid check.

How can I force the form to become "invalid" again, once my own  
validation detects errors?

Problem getting application to run with Apache2 and wsgi

[Jack Orenstein]

I'm running Django 1.02 and my application is running with the  
development server. I'm trying to move it over to Apache2 + wsgi.

Here is my httpd.conf setup for wsgi:

 LoadModule wsgi_module modules/mod_wsgi.so
 WSGIScriptAlias /foobar/ "/var/www/html/foobar/wsgi_handler.py"
 WSGIDaemonProcess foobar user=apache group=apache processes=1  
threads=10
 WSGIProcessGroup foobar
 
 Order allow,deny
 Allow from all
 

This isn't in a virtual host. My domain is geophile.com and I want my  
foobar application to be reachable at geophile.com/foobar.

When I go to geophile.com/foobar I get a 404 page:

 Page not found (404)
 Request Method:GET
 Request URL:   http://geophile.com/
 Using the URLconf defined in foobar.urls, Django tried these URL  
patterns, in this order:
 ^foobar/
 The current URL, , didn't match any of these.

What am I doing wrong?

Re: Location of files that are part of my application

[Jack Orenstein]

Sorry, I was unclear. I don't mean that these files contain python  
source code. They contain text that I want to read from certain  
requests to my app. So the question is where to put the files (under  
the app directory I assume), and how to refer to them using a  
relative path, or how I can discover the context to specify an  
absolute path.

Location of files that are part of my application

[Jack Orenstein]

I have a small number of files that need to be accessible to my  
Django application. These are part of the application, and so should  
be treated as source code. The question is where to put them? Putting  
them under MEDIA_ROOT doesn't seem right. They go with the  
application so they should be somewhere under the application  
directory. Suppose I put them in APPLICATION_NAME/resources -- how  
would I then refer to these files? I obviously don't want to code an  
absolute path into my application.

That would be nice. Do you know when this is expected to materialize?

But that includes the default formatting I'm trying to get rid of.  
E.g., for the radio example:


 male
 female


I want to get rid of the ul and li tags, and just put a  between  
the two inputs.

I'm going to try subclassing RadioSelect and overriding render.

Customizing HTML

[Jack Orenstein]

I'm new to Django, and making good progress rewriting a Struts-based  
website. (It started rotting because I found Struts so painful and  
non-intuitive. Django is so much easier.)

The major problems I'm running into have to do with HTML generation,  
first with error messages, and then with RadioSelect. In general, I  
don't like the, default, as_p or as_ul options. I'm also finding that  
the documentation on how to change the HTML is kind of thin, so I'm  
reading code and guessing. For errors, I ended up doing something  
like this:

 form.errors # Force creation of _errors
 errors = form._errors.items()

I now have a list of unformatted items which I can format anyway I want.

I'm running into a similar problem with RadioSelect. I found  
widgets.RadioFieldRender, but I can't extend it (it isn't exported).

So I have a question and a suggestion.

Question: How do I control HTML generation, ideally at field- or  
widget-level? I feel I must be overlooking something easy.

Suggestion: Instead of hardwiring formatting into Django, allow  
attributes to specify formatting. E.g., here is the minimal HTML for  
radio buttons for selecting gender:

 Male
 Female

I might want to generate some HTML before the first input, after the  
last, and between adjacent inputs. RadioFieldRenderer does this in a  
hardcoded way. How about providing, through the API, widget  
attributes such as 'before', 'after', and 'in_between'? These could  
default to what RadioFieldRendered does, but I could also substitute  
my own.

Django database connections

[Jack Orenstein]

I'm trying to understand how Django 1.0 handles connections. This is  
from the django docs, on the subject of raw SQL:

 from django.db import connection
 cursor = connection.cursor()
 cursor.execute("select ...")
 row = cursor.fetchone()

If I have a Django app running lots of requests, then how are  
connections handled? Is connection the same in each request, even  
requests running concurrently? That can't possibly be the case,  
(could it)? So does each request get its own? When are connections  
closed? When closed are they really closed, or just returned to a  
pool? Can the pool be configured, (e.g. to set the postgres  
search_path)?

Sorry to ask such basic questions, but I've been unable to find this  
information documented.

Adding fields to model objects that don't correspond to database state

[Jack Orenstein]

I have a model object that looks something like this:

   class Foo(models.Model)
   foo_id = models.IntegerField(primary_key = True)
   xyz = models.CharField(max_length = 20)

In my application, I'd like to add a list of Bar objects. It's like a  
foreign key, except that Bar objects don't exist in my databases. So  
I want a Foo.bars field.

- If I just create the field:

   class Foo(models.Model)
   foo_id = models.IntegerField(primary_key = True)
   xyz = models.CharField(max_length = 20)
   bars = []

Then the list belongs to the class, not instances.

- If I try creating the field lazily, e.g.

   class Foo(models.Model)
   foo_id = models.IntegerField(primary_key = True)
   xyz = models.CharField(max_length = 20)

   def attach_bar(self, bar):
   if self.bars is None:
   self.bars = []
   self.bars.append(bar)

Then calling attach_bar from the application results in an  
AttributeError, 'Foo' object has no attribute 'bars'.

- Specifying Foo.__init__ to initialize bars doesn't work, because it  
interferes with creation of Foo objects from database queries.

I played around with subclassing, e.g. class FooBase 
(models.Model) ... class Foo(FooBase) but couldn't get that to work.

How can I add a field to the Foo class that doesn't come from the  
database?

This is pretty simple, I agree. I came up with this exact code, but  
then ran into the FK problem, at which point I started wondering if I  
was just going about things the wrong way.

Integrating raw SQL and model objects

[Jack Orenstein]

Hello, I am new to Django, and trying to figure out how best to use  
it. My immediate problem is that I'm trying to figure out how to use  
raw SQL in combination with the model layer. Here are the issues I've  
run into:

1) How do I turn a row into a model object? There is some discussion  
of writing raw SQL in the docs (http://docs.djangoproject.com/en/dev/ 
topics/db/sql/#topics-db-sql), but I didn't see anything on turning  
the row into a model object. Do I need to create a dict from the row  
values and then call the model object's __init__ method? Or is there  
something simpler that I'm missing?

2) If the model object as a ForeignKey, then the construction of a  
model object is trickier. From playing around, it appears to be the  
case that the dict must have an object of the referenced type, not  
the value of the foreign key. This could make manual construction of  
model objects difficult. I must be doing something wrong -- forcing  
creation of the related objects seems wasteful, especially as it  
could propagate, (if the referenced object has its own FKs).

Re: Users getting logged out/cookie issues?

[Jack M.]

I'm fairly new to django, and I don't know it's intricacies very well,
but common sense says:

1.  Are they changing domains?  Maybe logging in on mydomain.com and
being redirected to www.mydomain.com ?

2.  Are they hopping IP addresses in the middle of their session?
Common for larger corporations with big honking proxies to the outside
world.

3.  Failing that, can you paste the information out of the cookie, as
it may provide more information?

i18n issues.

[Jack M.]

Hello, all.  Forgive me as I'm still fairly new to django, but I'm
having some issues getting i18n running, and I can't seem to find any
help in the online docs.

I've read chapter 18 (i18n) of djangobook.com, and chapter 10 relating
to RequestContext.  I've also read the docs on djangoproject.com for
the same subjects.

Basic problem description:  No matter what language I select, I get
English output.

My setup:
  OSX.5.3
  manually compiled gettext from source because xgettext was missing
from OSX.
  django from svn revision 7565 (did an update this morning).
  brand new project just for testing this functionality.
  mysql database (ran manage.py syncdb after getting the middle ware
setup).

What I've written:
  url r'^i18n/$' mapped to:  include('django.conf.urls.i18n') per
djangobook.com and djangoproject.com
  url r'^lang/' mapped to dolang from my views, which displays the
example code from djangobook.com on how to switch languages.  Changed
method="get" to POST so that it'll actually work.
  url r'^$' to hello_world from my views, which displays a template
say_hello.html with a simple string as output and a link to /lang/.

Hurtles I've already crossed:
  Made sure to use RequestContext in every (or both, whatever :)
request.
  Used make-message.py -l sp to generate the Spanish language files.
  Translated the two tokens (views.py:10, and templates/say_hello.html:
7) in the locale/sp/LC_MESSAGES_django.po file.
  Used compile-messages.py to compile the language into the django.mo
file.
  Ensured that the cookie is being set in my browser for the session,
and that the language is being saved to the session.
  Ensured that the language is in fact being saved to
request.LANGUAGE_CODE.
  Tried simply printing the string and bypassing the templates all
together.  Always outputs English.
  Pounded head into wall multiple times.

Any help is greatly appreciated.  I'm really excited about pitching
django to upper management and ridding myself of the perl hell I've
been tossed into.  ^_^

Below is the code, I'll leave out obvious things like import
statements.

-- views.py --
def dolang(request):
return render_to_response('dolang.html', {},
context_instance=RequestContext(request))

def hello_world(request):
string = _("Hello %(lang)s world!") % {'lang':
request.LANGUAGE_CODE}
print request.session['django_language']
print string
return render_to_response('say_hello.html', {'string': string},
context_instance=RequestContext(request))
-- / views.py --

-- urls.py --
urlpatterns = patterns('',
(r'^i18n/', include('django.conf.urls.i18n')),
(r'^lang/', dolang),
(r'^$', hello_world),
)
-- / urls.py --

-- templates/say_hello.html --
{% load i18n %}



{{ string }}

{% trans "Choose a language" %}


-- / templates/say_hello.html --

Re: Database Migration Question

[jack]

Russ - We had a few back and forths about this several weeks ago, if
you recall.  I now am much better versed in Django and so maybe a bit
more capable of making intelligent comments.

It would seem to me that with the primitives that I am seeking (which
is basically a continuation of hiding the SQL specifics of each DMBS
using Python code) all kinds of migration capabilities can easily be
implemented.  In fact, I can see several options, all valid, that each
developer can choose for their project.  That way Django would not
have to decide in advance how to do migrations.   Some may prefer
whole frameworks and specific methodologies, others will prefer to
roll their own.  For all intents and purposes, many of these
primitives already exist, at least for the initial creation of tables
from model class definitions, why not extend it to the next level and
provide the same toosl for Django developers to create tables and
modify them?  Seems like a natural to me.  I would write it myself,
but I am too rusty with SQL and the different syntaxes across
databases to be able to really dive in at this point.  But I would
enjoy collaborating on design and proposed implementation with anyone
who was willing and capable of tackling this task.

Database Migration Question

[jack]

Are there any Python/Django methods that represent generic database
commands such as creating a new table, renaming or dropping a column,
etc.?  My thinking is that if these generic methods existed, so that
all I needed to do was specifiy the correct info abt my DBMS in the
Settings file, I could create my own migrations as custom Views.  I
could invoke these via the web as well after having copied my latest
code to my production server.

If these methods do not exist, how difficult would it be to create
them?
