Scanning Uploaded Files

['Aaron Wilson' via Django users]

What is the recommended method to scan uploaded files for viruses? I see a 
lot of information about pyclamd which appears to be unmaintained.

New User Authentication Guide (:

[Aaron Harris]

Hi all, pretty excited about our new guide to Django User authentication on 
the Kite Blog .
Nice to have a reference if authentication maybe isn't your *favorite* part 
of webdev.

Why does SelectDateWidget ignore empty_label when field is required?

[Aaron Scruggs]

Greetings,

I have a ModelForm with a required date field that I am using 
SelectDateWidget with. I would like to default the select fields to empty 
placeholder values and force the user to pick a specific date, rather than 
defaulting to the first possible one. However when I pass empty_label to 
the widget the values are ignored, since the field is required. I could 
probably sub-class SelectDateWidget and change it to get the behavior I'm 
looking for, but after looking at the code and documentation it's clear 
that the current behavior is a deliberate choice. My question is: Why are 
placeholders ignored when the date field is required?

My use case doesn't seem that unusual so I'm guessing there's a strong 
reason why it's not supported. I'd love to know what that reason is before 
I go making a mess of things. Any help is much appreciated.

Thanks,

Aaron

Project Setup Checklist. Found this helpful...

[Aaron Harris]

Just curious how your project setup compares here and other resources you 
might suggest. Thanks!!

*Easily Install Django: A Quick Guide*

*Installation*
Assuming you have Python setup with pip – installation is simple. This will 
install Django along with a useful command that will help you get a project 
started quickly.

pip install django
The following command creates the project directory foo/ and creates a 
basic project structure and some initial files.

django-admin startproject foo
Let’s quickly go over each file we created:

Manage.py is the command-line utility that Django provides. It comes with a 
number of commands that are supported out of the box, some of which we’ll 
see later. Some Django applications that you may install later on will add 
commands accessible through this utility, and ultimately you’ll be able to 
add your own as needed.

foo/settings.py is n initial example of a Django settings file that should 
contain all the configuration for your application. If you take a look, you 
will see the default values that set your application up for running in a 
local development environment.

foo/urls.py is the default location for your URL configuration. Essentially 
this provides Django with the rules of how to route requests your 
application receives.

foo/wsgi.py is where the actual WSGI application lives. When running Django 
in production, you’ll want to use a server like uwsgi or green unicorn, 
whose servers interface with the application that resides in this file.

Now that we’ve created the project, let’s take it for a spin. To run the 
built-in development server, run:

./manage.py runserver
You should see some output indicating the settings used and where the 
server is available. Note that by default, it makes the server available at 
http://127.0.0.1:8000. If you go to that address, a default page will load, 
letting you know that you have successfully installed Django. As the page 
indicates, the only reason you’re seeing that page is because the default 
configuration provided in the settings.py file has DEBUG = True. Otherwise, 
trying to reach that page would give you a 404 as your URL configuration in 
urls.py doesn’t route that path to anything within your application.

‍
It's not that long but a bit too much for this post*. The rest is here 
:*

Hi, a little help here.

[Aaron]

I wasn't sure where to ask this question and then I found this place. I've 
got a MacBook running mac OS High Sierra.  I've been trying to install 
Django for a while. Whenever I try, I get an error that says "Command 
"python setup.py egg_info" failed with error code 1 in 
/private/var/folders/8y/lq4gsyx97_q171qrh2q18z0hgn/T/pip-build-cZ0Fno/django/"
 
in terminal. I'm not sure what to do. Thanks.

Re: DoesNotExist behavior in db.models query.py

['Aaron C. de Bruyn' via Django users]

The difference between .filter() and .get() is definitely 'by-design'.

When you filter through a list of objects, you could end up with zero,
one, or many objects returned.

When you call .get(), you are basically saying "I want to get exactly
*one* record".  If the record is not found, it is considered an error.

One additional difference is that .filter() returns a list of zero or
more objects whereas .get() returns the object you requested or it
throws an error.

You can catch the error calling .get() like so:

try:
   Person.objects.get(pk=123)
except Person.DoesNotExist:
  print("That person did not exist")

Heroku Git Error

[Aaron Weisberg]

Hi everyone,

It's a miracle I've gotten this far with the amount of knowledge that I 
don't have with coding, hosting, django, heroku, git etc.  However, I've 
been using a heroku server to serve my website for the last couple of 
months and I've been able to do so without any issues.

However, last week I was away from my office and i tried to make some 
changes to my site via a new machine, which I knew was a bad idea.  I 
committed one change, never pushed it using "git push heroku master" and 
then deleted the change using git reset


Now that I'm back in my office at my original machine, I'm having all sorts 
of issues and I cannot commit any changes or even hookup with git on the 
same page.

When I try to push to heroku master I get:
![rejected] master --> master (non-fast forward)
error: failed to push some refs to 'https://git.heroku...
Updates were rejectred because the tip of your current batch is behind its 
remote counterpart.  Integrate the remote changes (e.g. git pull) before 
pushing again

okay- well that's all well and good, but I can't perform git pull, git 
fetch or anything along those lines either.

I get:

Permission denied (publickey) fatal could not read from repository
Please make sure you have the correct access rights and the repository 
exists

Please help!

Thanks,

Aaron

Re: Django template iterating through two dictionaries/variables

[Aaron Weisberg]

Thanks Asad. Is that why I'm getting errors saying invalid filter name?

Also I'm having a difficult time thinking my way through the workflow. I'm
defining a new function that requires scores(my URL based dictionary) and
person (my database dictionary). The function then asks to return the
scores of the corresponding game number. Then the template is looking for
the correct value in the scores dictionary that has the same Number
identification as the existing person.Number?

I think what is confusing me is the use of "player" in ludovics example

Thanks

Aaron

Re: How to set up a form from an existing view

[Aaron Weisberg]

Thanks ludovic

I'll try that. I have a very basic form question. What attribute gets
posted in the .POST? Is that value? In input?

Secondly, the default value in the function, is that a type like text or
integer or is it just a place holder like "Chicago" or "2"

Thanks

How to set up a form from an existing view

[Aaron Weisberg]

Good morning,

I have been working on an app displaying some analytics and I want to 
incorporate some user feedback and I am having trouble figuring out how:

I have a detail view:

Enter code here...

#views.py
def detail(request, game_id):
games = Game.objects.get(pk=game_id)
context = {
'games':games}
return render(request,'myapp/detail.html',context)

Very simple with no form activity as of yet.

My template currently shows a comparison between two properties set up like:

#detail.html






{{ games.roadTeam }}
{{ games.roadTeamWins}} - {{ 
games.roadTeamLosses}} 
 
   


{{games.homeTeam }}
{{ games.HomeTeamWins}} - {{ 
games.HomeTeamLosses}}
 




I would like to work backwards and turn this template into a form.  Would I 
be able to make it a form by adding a third div to each one of these that 
is a button which sends the value of the variable back to the view?  and 
then how would I be able to process that in the view?
Enter code here...


{% csrf_token %}




I am not an expert when it comes to forms, so your assistance would be 
greatly appreciated.

Thanks.

Django template iterating through two dictionaries/variables

[Aaron Weisberg]

I didn't really know how to label this question, but I think it's an 
interesting concept and I haven't seen a resolution anywhere else.

I currently have two different dictionaries as context for a template:

Enter code here...context ={
 'person':person,
 'scores':scores,
   }


Each of these dictionaries has a common key (person.Number), 
(scores.Number), however the person dictionary is based off of a model in 
my django database, while scores comes from a json feed that I parse 
through:

I currently run through a table in a template that looks like this:

Enter code here...
  
  
  Person
Person Number
First Name
Last Name 
 City  
 Score 
  
  
  
   {% for person in persons %}
  
  {{ person.Number }}
  {{ person.firstName }}
  
{{ person.lastName }}
  
{{ person.city }}
  
??'''scores.score1 goes here'''
 
 {% endfor %}

  

What I'm trying to figure out to do is figure out how to get that final 
detail loaded into the table where we would find the score specific to that 
person.Number.  In other words how to go through my scores dictionary in 
this template and find the corresponding score1 using the person.Number 
from the other dictionary as the value.


Let me know if you have any ideas.

Thanks.

Re: Python dictionaries saved to models

[Aaron Weisberg]

Thanks.  

However, when I write the function and try to run the data migration I run 
into this error:

Enter code here...NameError: name apps is not defined

That is coming from this line in the migration:

Players = apps.get_model("team","Players")

This is a copy/paste from the documentation.  Is there a typo?

Thanks.

Re: Python dictionaries saved to models

[Aaron Weisberg]

Great- thanks Tim.

I understand the Python, but what I guess where I'm fuzzy is where to 
exactly put that code.  

Do I put it in the models.py? class.py?  and how do I execute?

That is the final piece of the puzzle for me.  

Thanks so much.

Python dictionaries saved to models

[Aaron Weisberg]

Hi everyone,

I have several dictionaries that I would like to import into my django 
project database, but I can't figure out exactly how.

I have tried to implement through fixtures, through views and through 
loaddata, but I must be doing something wrong at every turn- so if someone 
could suggest a workflow, it would really help me a lot!

My data is currently in a list of dictionaries called data:

Enter code here...data = [{'pos': 'position', 'player': 'name', 'ht': 
'height', 'wt': 175, 'birth': 'September 9, 1967', 'college': 'university', 
'number': 10, 'exp': 1},


each dictionary within that list is a "player" who I'd like to input his 
data into my model "Players"

Enter code here...
#models.py
class Player(models.Model):

number = models.CharField(max_length=2)
player = models.CharField(max_length=50)
position = models.CharField(max_length=2)
height = models.CharField(max_length=50)
weight = models.CharField(max_length=50)
birth = models.DateField()
exp = models.CharField(max_length=50)
college = models.CharField(max_length=50)
def __str__(self):
return self.player


There are about 500 players in that list of dictionaries above that I would 
like to insert into this model.

1) Can i run a function in the model above to insert the data into its 
appropriate field?  If so, how do I execute that function?
2) If it's a view that I need to execute-  do I just put the function in 
views.py?  How then is the dictionary imported into the database?

or... How would you go about getting that data into your database?  Please 
note that the data is coming from a url that might change from time to 
time.  But I think once i get the first iteration of data into these models 
I can figure out how to update.  But the only way I can figure out is to 
create them one by one in the shell or create a form and input them one by 
one.

If you have a solution, please share and be as detailed as possible since I 
am a complete beginner with django.    

Peace and love,

Aaron

Re: Storing data before committing to data base, wait for approval of admin

[Aaron Cannon]

I'd probably just keep a seperate table for all the edits, with a
foreign key pointing back to the record to be updated.  Seems like the
simplest layout to me, unless there's some complicating factor I'm
overlooking.

It would have a field for each field that edits can be suggested for,
a foreign key pointing to the person who suggested the edit, and
perhaps a flag for approved, rejected, or pending.  You might also
want to allow the data fields to be blankable and nullable, so you can
distinguish between a field where no edit was suggested, and one that
was suggested to be emptied, provided that there's a way for the user
to make that distinction in the user interface.

Not sure if this is what you were looking for or not.

I fear doing this efficiently is beyond my limited abilities.  Will

Re: Querying a model with a ForeignKey

[Aaron Cannon]

Does

pModel = PostModel.objects.filter(topicid_id=pk).order_by('-pub_date')[0]

work for you?

Also, I believe it would be more conventional if you named your
topicid field simply topic, your post field as body, and your topic
field as name.

Luck.

Re: Complex content type

[Aaron Cannon]

To your Answer class, you could just add a field like:

question = models.ForeignKey(Question, on_delete=models.CASCADE)

It may be as simple as that.

Does that help?

Re: Is it good idea to transition from MS Access to a webapp? And if so, is Django a good tool to do it?

[Aaron Cannon]

On the other hand, if you don't anticipate hundreds of users, then a
cheaper option like Digital Ocean may meet your needs better.  There
minimal servers start at $5/month.

Don't get me wrong, I love Aws, and I use it all the time.  It just
sounded like your needs were modest, so thought that might be a better
fit.

Aws may have a bit better stability than DO in the long run, but for
the apps I run there, uptime has not posed a problem so far.

Good luck with your app, and have fun.  I know I certainly have with
this framework.

Migration bug in 1.9.5?

[Aaron C. de Bruyn]

* My project has been around since the Django 1.2 days.
* Some time around 1.8.x I ran squashmigrations and everything worked
perfectly.
* I've done lots of migrations since then.
* I updated the app to Python 3.
* Everything was working perfectly

I just did my first makemigration under python 3.  Specifically I added a
Boolean 'enabled' field to a model.

The migration appears to have been created properly, but when I try to run
the 'migrate' command, it tries to apply
0001_squashed_0009_auto_20150109_1447.

I tried to fake it by running 'manage.py migrate myapp 0001 --fake' and it
says it applied (faked).
Running 'manage.py migrate' shows it trying to apply the 0001_squashed...
migration again.

I also tried using the --fake-initial flag with no luck.

'showmigrations' show every migration since the squash has been applied,
just not the squashed migration or the most recent one I just created:

myapp
 [ ] 0001_squashed_0009_auto_20150109_1447 (9 squashed migrations)
 [X] 0010_auto_20150109_1824
 [X] 0011_auto_20150818_1946
 [X] 0012_auto_20150829_1610
 [X] 0013_auto_20150829_1610
 [X] 0014_auto_20150829_1618
 [X] 0015_auto_20150829_1618
 [X] 0016_remove_internetprovider_old_phone
 [X] 0017_office_linked_location
 [X] 0018_auto_20150829_2345
 [X] 0019_office_pib_version
 [X] 0020_auto_20150908_1643
 [X] 0021_internetservice_notes
 [X] 0022_office_last_router_backup_alert
 [ ] 0023_auto_20160412_1433

How can I get the system to recognize that 0001_squashed... has been
applied already?

Thanks,

-A

Re: Fabric - Someone has a fabfile to build a Sentry server?

[Aaron C. de Bruyn]

Another fun way to deploy it is to a dokku (or Heroku) server.

Create a git repo with a requirements.txt that includes:
sentry[postgres]
psycopg2

Create a Procfile:
web: sentry --config=sentry.conf.py start
workers: sentry --config=sentry.conf.py celery worker -B

And finally a sentry.conf.py with the appropriate settings.

'git push' and wait a few minutes.

Re: NAS using Django

[Aaron C. de Bruyn]

That's still pretty vague.  What 'file sharing protocols' are you talking
about specifically?  And what do you mean by wanting to 'connect' the file
sharing protocols to the application?

There is a PySMB library that will allow your Django application to pretend
to be a Windows client.

If you're just talking about having the Django application display existing
files/mounts, there are various built-in tools for that.

You might want to take a look at the FreeNAS project.  They have a Django
application running as a front-end to their FreeNAS appliance.

[no subject]

[Aaron C. de Bruyn]

A simple annotation broke when I migrated by app from Django 1.8.x to
1.9.2, and I can't figure out why for the life of me.

Calling Company.objects.all().annotate(ticketcount=Count('srservice'))

throws an error "ProgrammingError: column "company.owner_id" must appear in
the GROUP BY clause or be used in an aggregate function"

Rolling back to Django 1.8.5 fixes the problem.
The DB backend is Postgres.

Please ignore the horrible DB schema.  It's not mine.  It's an
introspection of a horrible Windows ticketing app.

Models and traceback here:

Re: Concatenate complex views

[Aaron C. de Bruyn]

I may be missing something, but couldn't you use a generic ListView and
something like:

{% for car in car_list %}
  Car Make: 
  ...etc
{% endfor %}

Don't include a  tag or a submit button and you should get something
that looks like a form, but is read-only.
Maybe even disable the input box so it still looks like a normal input box,
but you can't click/type in it.

Re: How to display a image which is generated in the backend with Django

[Aaron C. de Bruyn]

If I recall correctly, the 'wc' object would need to be a file object.  You
could assign it similar to this:

from django.core.files import File
wc = File(open('/path/to/image', 'r'))
user.userprofile.tagcloud = wc
user.userprofile.save()

If the 'wc' variable returned by your program is already a file-like
object, you don't have to perform the 'open' step.

MEDIA_ROOT and MEDIA_URL can be whatever you want.  The ROOT is where the
files will be stored on disk, and the URL is where they should be
accessible via URL.  For example, most of my projects have:

MEDIA_URL = '/media/'
MEDIA_ROOT = 'media'

To display it in a template, try something like:


It's been a while since I've used ImageFields, hopefully someone can
correct me if I missed something.

Re: Password protect content

[Aaron C. de Bruyn]

You might want to check out Apache .htaccess files for securing the files.
Django sounds like it might be overkill for password protecting files.

Re: Team project via Git repo

[Aaron C. de Bruyn]

Without knowing too much about your environment, I figured I'd tell
you how I do it on my Debian-derivative systems.

* Install python-virtualenv and virtualenvwrapper - These tools help
you create isolated python environments under your home folder under
'.virtualenv'.
* Create a virtualenv for the project.  If my project name is CarSite
I run 'mkvirtualenv carsite'.  (After the virtualenv is created it
should leave you *inside* the virtual environment)
* Install the latest version of Django into your virtual env by
running 'pip install django'
* Create your project by going in to your code folder (this is
different than your virtualenv) "cd ~/code" and then creating the
project "django-admin startproject carsite"
* Go in to the carsite directory "cd ~/code/carsite"
* Create a requirements.txt file for other developers ('pip freeze >
requirements.txt')
* Turn it into a git repo "git init ."
* Commit your new project (or make changes, then commit) "git commit
-m 'My first commit'"
* Connect it to github by following their directions (something like
'git remote add origin g...@github.com:username/carsite.git' and then
'git push -u origin master')

Now other developers should be able to start working on the project by
doing the following:
* cd ~/code
* git clone g...@github.com:username/carsite.git carsite
* cd ~/code/carsite
* mkvirtualenv -r requirements.txt

Re: Platform.sh alternative for Django?

[Aaron C. de Bruyn]

Heroku is another paid alternative.

For myself, I purchase a $5/mo digital ocean server and install
'dokku' (https://github.com/progrium/dokku) so I can 'git push'.

For automated builds I use Drone CI (https://github.com/drone/drone)
which can also be installed on the same (or a separate) server.

If you need more and more resources as things grow (Redis, Postgres,
MySQL, etc...) you can either spin up additional cheap servers, or
'grow' your existing servers.

Re: Security News?

[Aaron C. de Bruyn]

I personally follow a few:
* The security mailing list for the distos I use (mainly ubuntu-security)
* FullDisclosure mailing list
* Slashdot ;)
* SoylentNews
* Listen to TechSNAP on Fridays (http://www.jupiterbroadcasting.com/)

If you're really hard-core you can get the CVE feeds:

Hope that helps.

That's not really a question about the language.  Developers can do
all sorts of amazing stuff with Django.  I was surprised to find
Disqus was written in Django.  Could I do it?  No.

Re: What Did I Do Right? (url and domain name change)

[Aaron C. de Bruyn]

1. DNS doesn't really work that way in most situations.  Your browser
should cache it, your computer should cache it (especially Windows),
and your upstream DNS (usually your router) should cache it.  Your
computer literally stores 'mysite.com' = '1.2.3.4'.  It doesn't store
it per-page, but for the whole domain name.

2. How are the URLs generated in your application?  If your HTML
template literally has:  http://mysite.herokuapp.com/{% url
'home' %}">Home pagethen the only way to update the URLs for
your app would be to edit the template and fix them.  If you are
relying on django-sites to 'know' the base URL for your site, go into
the admin section and click on 'Sites'.  I think it's best practice to
not prefix my URLs with http://whatever...  Just use {% url 'home' %}
as it should return something like '/' for the URL (without
http://mysite.com).

A. Your ALLOWED_HOSTS setting should probably have both domains if you
want your transition to be smooth.  (i.e. the site works through both
URLs).  ALLOWED_HOSTS has no affect on what URLs you application
displays.

B. Definitely not.  Tweak, break, learn.  ;)

Hope that helps.

Re: Help me develop a Job Tracker (?)

[Aaron C. de Bruyn]

You might be looking for the FormWizard.

In the latest version of Django, it has been moved to an external
application 
(https://github.com/django/django-formtools/blob/master/docs/wizard.rst).
In older version of Django, it is part of the corp app
(https://docs.djangoproject.com/en/1.7/ref/contrib/formtools/form-wizard/).

Re: Python & Django.

[Aaron C. de Bruyn]

I have a django project running under Python 3.4, so I don't think
it's a problem with Django.

If you can provide us with *any* information that might clue us in to
what is going on, it would be helpful.

At the moment, all we know is that something doesn't work.

Can you provide information on what version of Linux, Windows, or Mac
you are using?
Commands you are typing in and the responses you are getting?
Does 'python manage.py runserver' produce any output?

Thanks,

Real time and Django - approaches

[Aaron Reabow]

Hi.

I wanted to see what the Django community thought about realtime circa 2015.

My impression (and I could be very wrong) is that if you want real time, 
you should build your own stack up from scratch.  There are frameworks - 
like swampdragon/socketio - that promise to do the hard yards for you, but 
ultimately are either based on older versions of the underlying tech, or 
too green to be in production.

So which stack to build?  There is the gevent route which looks promising 
as it keeps it all in the python family.  (Stack would be something like - 
django/redis/gevent/gunicorn)

>From what I have read, gevent becomes opaque and throws up hard to 
understand errors.  Without a strong community behind this, debugging is 
either for the advanced, or extremely dedicated.

Another stack option is to use Node.  I quite like this, despite the 
challenges.  The stack would be django/apache +redis/socetio/node/celery. 
 I think the hardest part would be managing oauth2 between the two servers. 
 On the upside, django can do all the regular web stuff, with node handling 
realtime components.

So I have just stated my own views from what I could glean from blog posts. 
 I was interested if people had alternate understandings.

What I am building definitely does need pubsub at the least, and to be as 
near to realtime as possible would be an advantage.

many thanks,

Aaron

Okay great, thanks.

I wrote a basic view, and it seems to do the job.  So far so good :)

I know (of) DRF, but not tastypie - will have a look.

ajax philosophy

[Aaron Reabow]

I would like to separate out my ajax requests into their own views (one per 
page, is what I am thinking)

This allows me to keep a very generic base view that applies to multiple 
pages.  This have a number of advantages for me, such as building a bullet 
proof view that never gives any trouble :)

Really what I am asking is - from a conceptual level, are their any serious 
reasons why this approach would be a bad idea?

(I am just taking my first steps into the world of ajax, hence the beginner 
question)

Re: Django development running on 127.0.0.1:8000 not accessible from same machine

[Aaron C. de Bruyn]

If it still doesn't work after doing what James suggested, you can look to
see if python is actually 'listening' on port 8000.

>From an 'elevated' command prompt (start->type 'cmd', right-click 'cmd' and
hit 'run as administrator') type 'netstat -abno > netstat.txt' and hit
enter.  Then type 'notepad netstat.txt' and you will see a list of all the
ports and programs that are using them.

Use the 'find' feature in notepad to look for a program running on '8000'.
If you don't see Python, something is not working correctly.

Occasionally you might see another app that is using the port.  A few years
back, Windows Small Business Server would occasionally seize random ports
used by other applications for use for DNS queries.

Re: Deploying Django on Docker

[Aaron C. de Bruyn]

My docker setup is pretty easy:

wget -qO- https://raw.github.com/progrium/dokku/v0.3.13/bootstrap.sh |
sudo DOKKU_TAG=v0.3.13 bash

cat ~/.ssh/id_rsa.pub | ssh r...@mynewhost.mydomain.tld "sudo
sshcommand acl-add dokku myproject"

git remote add production do...@mynewhost.mydomain.tld:myproject

git push production master


Dokku is awesome.  ;)

Re: Swampdragon, the realtime framework for Django seems interesting. But will it scale ?

[Aaron Reabow]

the thing i am trying to figure out is how this works with my existing 
setup.

I get that you need to install redis. but how does the rest of the stack 
change

mine is through the good people at webfaction:

apache tomcat
nginx (static)
postgres
python2.7
django1,6
html/css/js

how much of this can i leave alone, while installing redis?

Re: Obtaining content from Git

[Aaron C. de Bruyn]

I'm not aware of any such module, but there are a few python 'git'
modules for reading/writing, etc...

As for how much trouble it would be, that all depends on how familiar
you are with git, python, Django, and the template system.

One way you might be able to achieve what you want is to create your
own template tag.  (The documentation is here:
https://docs.djangoproject.com/en/dev/howto/custom-template-tags/#writing-custom-template-tags)

You could pass a few parameters to your tag--I'm not sure what you're
looking for, but maybe:

{% gitfile "myfolder/myfile.txt" "d4ea4eea799" %}

And your tag could load data from "myfolder/myfile.txt" at revision
"d4ea4eea799".

There are a few exampled in the Django code itself
(https://github.com/django/django/tree/master/django/templatetags) as
well as plenty of samples on the internet for writing your own
template tag.

Re: Is there anything similar to phpmyadmin

[Aaron C. de Bruyn]

You might consider setting up your database connection string, then doing a
'python manage.py inspectdb'.

This will spit out a bunch of model definitions.  Paste them into your
models.py, and add them in admin.py, and you have an interface for managing
a database.

Re: Updating Django project from 1.4 (if not older) to 1.7

[Aaron C. de Bruyn]

It depends on a lot of things.

1. You can try running:
python
from django import get_version
print get_version()


2. If you don't see manage.py in the root directory, you are probably using
a very old version of django.  I would start by creating a virtualenv
running an early version of Django (maybe 1.2) and get the application
running.  Then slowly upgrade (1.3, then 1.4, etc...) until you get up to
1.7.  Follow the upgrade instructions here:
https://docs.djangoproject.com/en/1.7/releases/

If there isn't much code to the app, I would start with a clean project and
slowly move the required apps over to the new project.  But it all depends
on the time you have available and the amount of code to work with.

3. Follow the steps in the release notes.  Possibly use a tool like 'grep'
if you are in a Linux environment to search through the code for deprecated
modules.  If the application has a good set of tests, they should tell you
what's broken.

4. Depends on how much code, how much time, and how efficient you are as a
programmer.  If you've got four weeks, but only need 90 minutes of sleep
every night, most projects can be re-written from scratch.  ;)

If it seems too daunting, you can always post specific questions herep--or
even find someone (https://www.djangojobs.net/jobs/) to help you
professionally.

Comments in real time

[Aaron Reabow]

Hi all,

I use a proprietary application that let people on multiple browsers 
comment.

In real time their comments are displayed for everyone to see.

What is quite nice, is that you can then order and group these comments.

I have looked through the Django apps, but am unsure if any of them will 
give me similar capabilities (or parts thereof).

Would anyone have a suggestion on where to start looking.  My alternative 
would be to then build the interactivity in javascript.

many thanks in advance,

Aaron

Should I use generic foreign key, and how?

[Aaron Law]

Hi all,

I have php web programming background, and new to Django. I am helping my
brother to build an online system to manage inventory, and I've got a
database design & coding problem recently. Needing help!

That is, I have a set of tables of "possible products", "inventory",
"suppiler", etc. I want to attach a "comment" to each of them. Therefore, I
think I should make a generic "comment" table to hold all the comments of
products, inventory, suppiler.

--
possible_products
id: int (pk)
name: varchar
url: varchar
price: decimal
created_at: datetime
updated_at: datetime
--
comments
id: int (pk)
parent_id: int (fk)
content: text
author: int (fk)
table: char (which the table this comment belongs to)
created_at: datetime
updated_at: datatime
--

My problem is, when "possible_products" table is the parent of "comment",
then a foreign key of the parent (id number) is stored in the "comment"
table in order to link up them.

However, how about the fk of the "inventory" table and the "suppiler"
table? It should not be that: I create 2 more columns of "inventory_id" nor
"suppiler_id" in "comments" table. (That is, I should not create the 4th
column when I want to link up the 4th parent table.)

So, Should I use generic forgien key of Django? (so that, my "comment"
table design is right.) And how to use/implement it?

P.S I mainly develop the system in the Admin section of Django.

Regards,
Aaron Law Ho hon

Re: Simple History - Field Change

[Aaron Reabow]

You are totally right.

There is a historical table that required deletion.

This is why you shouldn't debug late on friday afternoon.  I had actually 
looked for that table but somehow missed it.

I will pick up the broader problems with simple history separately.

thanks for taking the time to look through this Cal.

Simple History - Field Change

[Aaron Reabow]

Hi all,

I am getting this error on a modelform

smallint out of range



But the form is actually submitting just fine and being stored in the DB.  I 
used to have a positive small int, but have changed it  (dropped the offending 
table, resync'ed, restarted the server...)

I have history = HistoricalRecords() as one of the fields  (ie am tracking 
changes with django-simple-history), and I wonder if this is effecting my 
ability to make changes to the model.


My other thought is that it is a caching problem somewhere.


has anyone come across this problem and have any idea how to fix?


many thanks,


Aaron

Re: Using session data to populate multiple forms

[Aaron Reabow]

haha - okay

*model_instance.participant = request.session.get('participant')*

works perfectly.

I thought the incorrect use of objects was just the start :)

Thanks Daniel, much appreciated.

Re: Using session data to populate multiple forms

Perhaps I should be more specific.

How do i populate some fields in a table from a form, and other fields from 
session variables in the view  (or the template or the model if that was 
more appropriate)

many thanks,

aaron

Re: Using session data to populate multiple forms

[Aaron Reabow]

Hi Daniel,

Thanks for the response. 

What I am trying to get right is the ability to save session data across 
multiple forms.

In an initial form, people can tell me some generic information about their 
department, role etc.

It is then useful for me to save that information alongside their answers 
in subsequent forms that they complete within a session.  (It helps me to 
know who is who when I analyse their responses)

I save a little session dictionary of their core information in URL1 and am 
looking to add that information to the models that they complete in 
URL2,3,4...

I hope that makes some sense.

warm regards,

Aaron

Using session data to populate multiple forms

[Aaron Reabow]

Hi All,

I have been scratching around this for a bit now.

Sometimes I *don't want people to have to register* on my site, but I do 
want to *capture some information* about them and *reuse it across multiple 
mini questionnaires/forms*.

I can happily set and get a session variable using the session 'dictionary'

What I am trying to figure out is how to then use this information to 
populate fields so I can know who is giving which answers.

I could take the session variable and write this to the template, grab this 
information in the template and write it to the input using jquery.  This 
doesn't seem the most efficient way.

I assume writing this information in the view would be optional, 
alternatively is there a way to foreignkey type of approach.

Also I am pretty new to django so i might be way off the mark..

many thanks in advance,

Aaron

my view:

def sessionStoreView(request):
if request.method == "POST":
form = sessionStoreForm(request.POST)
if form.is_valid():
model_instance = form.save(commit=False)
*model_instance['participant'] 
= request.session.get('participant') #something like that would be great if 
it worked*
model_instance.save()
return HttpResponseRedirect('sessionStore')
else:
form = sessionStoreForm()
return render(request, "sessionStore.html", {'form': form})

Re: Development SaaS with Django

[Aaron C. de Bruyn]

The best way to find out would be to download django-cms and django-shop
and test them out for yourself to make sure they meet your requirements.
 Or hire a developer to research your requirements for you.

My guess would be 'no', because their goal isn't to be multi-tenant apps.

Re: Avoid Django s3-urls stripping

[Aaron Cannon]

I'd like to try to reproduce this locally.  If you can send me the URL
(feel free to mangle the signature parameter for security), that will
help.  Alternatively, you might cut the URL into pieces, to see if
it's some specific characters that it's choking on, and then just send
me that bit.

Otherwise, if you'd like to create a small example project that
demonstrates this issue, and upload it to github, that would work as
well.

Re: Avoid Django s3-urls stripping

[Aaron Cannon]

Is the url a bytestring?  A quick check of the code for HttpResponse
shows that that class is expecting a byte string.  Perhaps the URL
contains unicode characters that aren't being escaped properly?

Re: Avoid Django s3-urls stripping

[Aaron Cannon]

Other things I'd probably try to debug this issue would be:

* Hard coding the string into the call to HttpResponse,
* printing the variable that contains the URL to the console.

If the URL was still bad after trying the first item, and the second
item printed the expected result, then you could completely take S3
out of the picture.  From there, I would start narrowing it down, to
see if it was a specific character that was causing the problem.

Narrowing things down a bit more might make it easier for folks to
help you figure out your issue.

Luck.

Re: Avoid Django s3-urls stripping

Try clicking view source in your browser when you view it.  Perhaps

Re: Displaying HTML forms through AJAX

[Aaron Decker]

Arun, 

Do yourself some favors.

1. use jQuery for Ajax (or some other lib). You are doing it the very hard 
and not cross-browser compatible way.
2. use Django's template system for HTML generation.
3. if you do number 2 you can embed the CSRF token in the template render 
like you are supposed to.

Expected Behavior with Proxy Models

[Aaron Spike]

I experienced some obscure test failures after integrating Zinnia with my 
application. I've tracked it down to the behavior of Proxy Models and I'm 
unable
to rationalize the documentation with the behavior I see. Here's what I've 
done
to understand the issue:

If I create an app with a Proxy Model for auth.User (using get_user_model):

# pm/models.py
# a stripped down copy of Zinnia's Author
from django.db import models
from django.contrib.auth import get_user_model

class MyUser(get_user_model()):
objects = get_user_model()._default_manager

def __str__(self):
return self.get_full_name() or self.get_username()

class Meta:
app_label = 'pm'
proxy = True

I see the following behavior in the shell:

$ ./manage.py shell
Python 2.7.4 (default, Apr 19 2013, 18:28:01) 
[GCC 4.7.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from django.contrib.auth import get_user_model
>>> get_user_model()

>>> get_user_model().objects.model

>>> get_user_model().objects.get(pk=1)

>>> 

This seems to be contrary to the claim made in the documentation:

"QuerySets still return the model that was requested

There is no way to have Django return, say, a MyPerson object whenever 
you 
query for Person objects. A queryset for Person objects will return 
those 
types of objects. The whole point of proxy objects is that code relying 
on 
the original Person will use those and your own code can use the 
extensions 
you included (that no other code is relying on anyway). It is not a way 
to 
replace the Person (or any other) model everywhere with something of 
your 
own creation."


https://docs.djangoproject.com/en/dev/topics/db/models/#querysets-still-return-the-model-that-was-requested


If I create a second app and model with a Proxy for auth.User:

# pm2/models.py
from django.db import models
from django.contrib.auth import get_user_model

class MyUser2(get_user_model()):
objects = get_user_model()._default_manager

def __str__(self):
return self.get_full_name() or self.get_username()

class Meta:
app_label = 'pm2'
proxy = True

Then I get an AssertionError with the following traceback:

$ ./manage.py shell --traceback

AssertionError

After the first Proxy Model is registered, self.model points at the Proxy 
Model 
instead of the original Model. The second Proxy Model is not a subclass of 
the 
first.

Is there a contradiction between the behavior I observe and the 
documentation? 
Or am I simply misunderstanding

Re: Django Gunicorn with Two Django App

[Aaron C. de Bruyn]

Just a stab in the dark, but are both projects using the same port?

Using gunicorn, you can set the IP and port the server runs on, then in
Nginx you need to tell each app to use the correct port.

Example from memory:

/home/aaron/app1 $ python manage.py gunicorn 127.0.0.1:8000

/home/aaron/app2 $ python manage.py gunicorn 127.0.0.1:8001

Then in the nginx config for app1 you need to point it to
127.0.0.1:8000and app2 needs to be pointed to
127.0.0.1:8001.

Re: broken packages

[Aaron C. de Bruyn]

This isn't a django issue, but rather an issue with the package management
system in your Linux distribution.

This can happen if someone publishes a broken package, or you add on PPA's
that have conflicting requirements.

Basically it's saying that geonode depends on a version of Django greater
than 1.5.1 but version 1.4.1 is installed.  It may be that 1.5.1 is not
available in your distro yet.

You might try the Debian or Ubuntu forums for further assistance.

There's lots to know.
My personal opinion is that you shouldn't take on too much at the start.
 If you know how to develop and market your app--stick to that.  Let
someone else host your site and deal with all the server stuff.

When your site starts getting wildly popular and you need to scale (or
hopefully a little bit before), start playing around on a test machine and
see what it takes to manage it appropriately.

Most of the servers I manage are Debian (or Ubuntu) based.  So the majority
of what I need to know is 'apt-get update && apt-get dist-upgrade' to keep
packages up-to-date, followed by a decent knowledge of Nginx (web server),
uwsgi (a WSGI...host?...that runs your Django app), MySQL or Postgresql for
your database,  followed by some basic SSH/SCP knowledge.  For Windows
users I recommend two tools:  PuTTY and WinSCP.  PuTTY will give you
command-line access via SSH on your server.  WinSCP is a nice
file-management GUI.

Not to say there isn't deeper knowledge required for tuning, caching,
firewalling, etc...but that's the majority of it.

If you ever have specific systems-management questions that aren't
particularly applicable to Django, Google is your friend--or shoot me an
e-mail.

Re: django windows user

[Aaron C. de Bruyn]

Google is your friend.

The first tutorial that came up when I searched for 'ssh for windows users'
was this site:
http://support.suso.com/supki/SSH_Tutorial_for_Windows

Do you have an existing Linux server at your house or with a hosting
provider?

If managing a Linux server is too steep of a learning curve, there are
several providers out there that will do that for you and provide you a
simple way to deploy your application.

A good resource is Django Hosting: http://djangohosting.com/

Each provider has different requirements for 'automagically' deploying your
site.  Some use 'requirements.txt' file or a 'Procfile'.

Some people find Heroku easy and cheap for deploying small test
applications: https://www.heroku.com/

If you have specific questions, please ask them and the community would be
glad to assist.
