Re: NoReverseMatch Error

[Syam Palakurthy]

Hi, Can you please elaborate on how to use this block in the template code? 
 I've tried adding this into my details template code in various places and 
cannot get it to successfully work.  Also, any suggestions/examples you 
could point me to would be much appreciated.

{{ poll.question }}

{% if error_message %}{{ error_message }}{% endif %}


{% import url from future %}


{% csrf_token %}
{% for choice in poll.choice_set.all %}


{{ choice.choice_text 
}}
{% endfor %}



Thanks,
Syam

I am new to django and CSS. Will try to do this. If you could kindly 
elaborate a bit more (perhaps give an example of how to define the widths 
in extrastyle.css, and where to keep that file), I shall be grateful.

I would want different width for each field. It is not clear to me how 
would your suggestion work since that seems to be specifying a single class 
for the entire fieldset.

In admin.py you can for example ...

'field_abc',

Re: New to Django, having difficulty creating first app. PLEASE HELP!

[MattDale]

Glad you are trying out Django.

That error is telling you what's wrong  The directory that you are in does 
not include the file "manage.py".  Depending on your operating system, when 
you get this error, get the contents of the directory(windows, type dir and 
press enter) if the outputted list doesn't include "manage.py", then you 
are not in the outer mysite directory.  You most likely did not "change 
into the outer mysite directory". So from that point in the tutorial, type 
cd ..  and press enter, and that should be the outer directory. just to be 
sure, check the contents of the directory you are in by typing "dir".  

Sorry if that answer is a little too basic and you already know all that, 
but I wanted to offer the simplest troubleshooting options first. 

Good luck

Hello everyone, 

I am doing the django tutorial. 
https://docs.djangoproject.com/en/1.4/intro/tutorial01/

I am on the part where it says, "The development server". It says: Let's 
verify this worked. Change into the outer mysite directory, if you haven't 
already, and run the command python manage.py runserver.

When I type in  "python manage.py runserver" on the command prompt, 
however, it says, "python: can't open file 'manage.py': [Errno 2] no such 
file or directory. 

What should I do? Can you please tell me?

I have done everything right so far. 

Thank you all so much, Luke

Re: Not sure how to describe issue/behavior with Form -- so here's code & YouTube video

[Barry Morrison]

Serge,
Thank you.
#92 is for the crispy form.

The crispy-form is the actual form, but the form is using a WYSIWYG editor
http://redactorjs.com/ and when I go to browse for an image it calls url
'photo-uploads' which calls the function 'upload_photos' in the view.

That view is necessary for redactor.js to get the image(s) from it's API
via json, so I understand why the view creates the object, but doing so, it
creates an empty field in the database.

I had separated the models, so I had an Article model and an ArticleImage
model, but then redactor.js failed to work (unsure how to create the
relationship in the crispy form or any form for that matter).

Thanks,
Barry

 Hello Barry !
 I would like to say that your are not novice. now and  your code is
really clear.
Could you please move  string #92  up  ? super should be called before
other field initialization.
look like your prev activity is stored  after init process and  those
data is saved at the save operation.
try to print form  to log after pressing cancel button

 thanks , serge

Re: CACHE_MIDDLEWARE_ANONYMOUS_ONLY does not work if user is not printed by view or template

[Bill Freeman]

While
  u = request.user
may not be enough,
  request.user.username
should be (I don't think you even have to put it in a variable, python
will evaluate it even if the result is discarded).

Re: Not sure how to describe issue/behavior with Form -- so here's code & YouTube video

[Barry Morrison]

For ease of use, let's take the cancel out of the equation perhaps.  

Url to create a new News Event: 
### Create News Article
url(r'^account/news/add/$', login_required(CreateView.as_view(
model=NewsArticle,
form_class=NewsForm,
success_url=("/account/news"),
template_name="account/news_admin.html")),
name="admin-add-news"),


Url that gets called when I chose to insert an image into the WYSIWYG 
editor (and calls 'upload_photos' that has the NewsArticle.objects.create())

### Redactor.js WYSIWYG Editor
###
url(r"^uploads/$", "web_site.News.views.upload_photos", 
name="upload_photos"),
url(r"^recent/$", "web_site.News.views.recent_photos", 
name="recent_photos"),

and the views themselves:

@csrf_exempt
@require_POST
@login_required
def upload_photos(request):
images = []
for f in request.FILES.getlist("file"):
obj = NewsArticle.objects.create(upload=f, is_image=True)

images.append({"filelink": obj.upload.url})
return HttpResponse(json.dumps(images), mimetype="application/json")


@login_required
def recent_photos(request):
images = [
{"thumb": obj.upload.url, "image": obj.upload.url}
for obj in 
NewsArticle.objects.filter(is_image=True).order_by("-date_created")[:20]
]
return HttpResponse(json.dumps(images), mimetype="application/json")


I've tried to set a .save(commit=False) on obj -- that doesn't work. 

I realize the behavior is call 'upload_photos' and it'll create the object 
in the database, but on any other event other than submission of the form, 
I want that object to no longer exist.  I guess I want it to ONLY get 
created upon form submission.

Django by Example: error with to do app; global name 'escape' is not defined

[koiwai]

Hi,

I'm currently working through Django by Examples and 
I am getting an error when attempting to have the user automatically go 
back to the listing of 'todo items'  after entering new 'to do items' 
through creating a new date. The 
siteasks us to 
copy a function from a template provided by django, and alter a 
couple of things. The code example and the template are a bit different 
post altering though (I guess this is because I am using 1.4;s default 
packages and presumably the author was using 1.2), but I don't think these 
are relevant to my problem (I use in rather than has.key etc)

Re: After form validation, need to post and call a perl program to display to a log file

[Nick Santos]

Obligatory followup (though the docs I believe cover this pretty well) - be 
*very* careful calling subprocess with anything related to a form 
submission. Read the documents that Melvyn linked to carefully because you 
can be opening a massive security hole. If this is just temporary to check 
some output, that's fine, but if you plan on going into production, make 
sure to know the risks and consider alternatives.

If you make that column a regular Column does it render properly? If not then 
confirm that you define the column exactly as it is spelled in your 
models.py(case and all). Once it renders properly as a regular Column, then try 
changing to a LinkColumn.

Re: Why is my groundwork in django show up in 404 page?

Hi there,

I have never worked with groundwork before, but it seems like you need the
newly created app URLs in your urls.py file. Something like this at the end
of your urls.py file may work.

urlpatterns += patterns('bookapp.views',
url(r'^book/list/$', 'VIEW_NAME', name='list'),
)

Ah, right it's not properly covered in the tutorial. Within the fields
member of the dictionary you can group them. Details are here:

Assunto: Re: Django-tables2

 

Here's an example of one of my tables.

 

class NeedsTable(tables.Table):

needQuantity = tables.Column()

prod_id = tables.Column()

description = tables.LinkColumn('needsdetail', args=[A('pk')])

department = tables.Column()

order = tables.Column()

priority = tables.Column(accessor='order.event.priority')

show = tables.Column(accessor='order.event.name')

preppedQuantity = tables.Column()

prepdate = tables.Column()



class Meta:

order_by = 'priority'

attrs = {'class': 'general_table'}

 

URLS.py - 

url(r'^qcarea/needs/detail/(?P\d+)/$', 'needs.views.needsdetail',
name='needsdetail') 

 

LinkColumn uses reverse() to get its view and you use the Accessor(A) to
pass the pk to the args of the reverse call.  This means that you must name
your URL in your urls.py.  

 

In your example, I can't quite figure out what you are attempting with the
TemplateColumn.  To me it seems like you need to create two link columns.  

Good Luck

Re: Django-tables2

[MattDale]

Here's an example of one of my tables.

class NeedsTable(tables.Table):
needQuantity = tables.Column()
prod_id = tables.Column()
description = tables.LinkColumn('needsdetail', args=[A('pk')])
department = tables.Column()
order = tables.Column()
priority = tables.Column(accessor='order.event.priority')
show = tables.Column(accessor='order.event.name')
preppedQuantity = tables.Column()
prepdate = tables.Column()

class Meta:
order_by = 'priority'
attrs = {'class': 'general_table'}

URLS.py - 
url(r'^qcarea/needs/detail/(?P\d+)/$', 'needs.views.needsdetail', 
name='needsdetail') 

LinkColumn uses reverse() to get its view and you use the Accessor(A) to 
pass the pk to the args of the reverse call.  This means that you must name 
your URL in your urls.py.  

In your example, I can't quite figure out what you are attempting with the 
TemplateColumn.  To me it seems like you need to create two link columns.  
Good Luck

The examples shown for fieldsets seem to divide the fields into
different groups. But in all the examples, fields still appear, within
each group, one after another, vertically.

Re: Django-tables2

[MattDale]

It is just a very easy way to create html tables with one simple template 
tag that have features like sorting by column, easy, quick css etc. without 
using javascript at all.  There are times when this is easier than creating 
a table and customizing it.  I use it for general tables that don't need 
any ajax features.  Although I've lately been creating manual tables and 
using the "tablesorter.js" to handle quick sorting.

Re: Context Help

[Gregory Strydom]

Thanks for taking the time to help out i really appreciate it :)

Im still a little confused so i think the best thing to do would be to 
start from scratch, going through the tutorial again, and again and taking 
things really slowly (slower thanks snails pace lol), and work through it 
step by step until i get a better understanding.

I think im getting frustrated as well because i kind of rushed through the 
tutorial as i am currently on a deadline with my company to get this 
project completed. I will just need to explain it is going to take a little 
longer than i expected and as i said take things very slowly and make sure 
i understand each step before moving on to the next.

What you guys said does make a lot more sense though, thanks again!

Contexts are used when rendering templates. All function calls that
render templates also take two additional arguments, which can be used
to populate a context. Eg:

render_to_string(template_name, dictionary=None, context_instance=None)

The context_instance here is the Context you wish to use to render the
template. The key-value-pairs in the dictionary are merged into a
supplied context_instance, or used to create a new Context if none is
supplied.

Finally, there is a sub-class of Context called RequestContext. This
is a context that is created with a request object. It will step
through each context processor defined in
settings.TEMPLATE_CONTEXT_PROCESSORS, and call the functioned
specified there, passing the request as the only argument. The
dictionary returned from this function is then merged into the
context.

All of this is documented on a single page here:

https://docs.djangoproject.com/en/1.4/ref/templates/api/

So, what does this mean? Well, typically on a "full fat" web page,
you'll want to use a RequestContext, so that common variables - like
the currently logged in user - are automatically available in your
template. Therefore, in a view, you will commonly have a pattern like
this:

def myview(request):
  ctxt = RequestContext(request)
  return render_to_response("myapp/myview.html", {
'hello': 'world',
'testing': '123', }, context_instance=ctxt)

Inside the template itself, the context is now the global scope.
Therefore, you don't refer to the 'name' of the context, eg in your
example, "{{ P.Name }}" is incorrect; the context has a variable
called 'Name' in it, so "{{ Name }}" is the correct usage.

Cheers

Tom

Layout of widgets in admin form

I am new to django. I am trying to develop an application where I need to

Because save complains loudly if it didn't work. It's kind of like
crossing the street: if you make it without feeling pain, you can be
sure you weren't hit by a car. There's no need to check your clothes for
any evidence of the contrary.

The reason database files do not grow in size on every new record is
because some space is pre-allocated and space previously occupied by
deleted records is reused if it fits to prevent large holes (meaning
more seeks).

Just a "heads up". This works as long as you only have factories. If you
add other entities like "exporters" and "wholesalers" you're going to
need generic relations:

I've not watched your video. I also have no idea what crispy forms
are, or what django form attributes are created using that syntax.
However…

Your model definition allows an empty form to be valid - none of those
fields are required AFAICT. Therefore, submitting an empty form using
the cancel button is being allowed to proceed. Therefore your check on
whether "cancel" was submitted is not working.

Put some debug here:

http://dpaste.org/az8Nb/#l28

Output what "submit" is, and all values in request.POST.

Why would you call an external script instead of importing a module
and calling a function? This seems sub-optimal.

If there is some really really good reason why you are doing this,
then the standard way to get output from an external script is to have
the script write to stdout, not a file, and have your view function
read the input. Something like this in your view:

import subprocess
content = subprocess.check_output(["python", "/path/to/script", arg1, arg2 ])
return HttpResponse(content)

I still think there is no valid reason to call an external python
script, simply import and call the function you want.

I agree that it's a POLA-violation and you should probably file a bug
report. I would expect that setting CACHE_MIDDLEWARE_ANONYMOUS_ONLY
would call request.user.is_anonymous() and as such load the lazy object.
For this to work, the cache middleware should probably be later in the
sequence then the authentication middleware.

httpresponse from stand alone script

[Blaxton]

Hi

I am calling a stand alone script from within views.py and 
was able to generate a html 
file with render_to_string in a stand alone script
by include followng line:
from django.template.loader 
import render_to_string

now , need to use "httpresponse" to generate a response.
is it possible ? tried importing httpresponse and then use
"return httpresponse" but got error from "return" as it is a stand alone
script and not a funtion. 


currently, I am writing the result of stand alone script to a file and then 
render it
in views.py.

If I could pass some variables to views.py , or if I could use httpresponse in
stand alone script , then there was no need of writing to a file and then 

render the file.

Thanks for help

but you see now an empty news event has been created
next action, I hit + again, add a new image, hit submit. success_url takes 
me go the view of all events, this time it created the form I submitted and 
created another empty one

The function in views.py "add_news_item" is not set up in the URL, but it 
does support the cancel on the form action. The video posted is using that 
view for the URL.  With the 'CreateView' in the URL, canceling the form 
will create an empty field in the database.  

Any help/guidance would be greatly appreciated!! 

Thanks!

database file doesn't increase in size

[heni yemun]

Hi,
When i create a user account, fill the fields with some value and save() it 
in the database file *myfile.db* for example, the file doesn't show any 
change in size. So how do i know if i'm actually saving it and can later 
access the values?  Or is there another problem i should deal with first? 
THANK YOU!!
