Versions < 0.9.8 expect a fully compliant (read: very simple) WSGI behaviour.

Actually the world is a bit more complex than this so in 0.9.8 i added a more 
"tolerant"
wsgi.input object. (pratically it is the same technic of mod_wsgi for apache 
with some addition)

Upgrading to 0.9.8.1 can bypass the issue or eventually throw an error pointing 
to what it is wrong
in django code.

giving download links

[raj]

I allow a user to upload a file, how do I now allow them to download
this file? I looked at the "serving static files" thing in the
djangoproject, but they said it causes security flaws or something.
Can someone help me? I couldn't find good information on google. Thank
you.

Re: How to add CSRF to context when using test client???

[andres ledesma]

Hi Matteius, I stumbled across the same problem.
I wanted to carry out a test case using CSRF, and I failed.
I managed to add the csrf_token to my post request, but
apparently this is not enough. Here I will show you the code,
perhaps you will have better luck then...

c = Client(enforce_csrf_checks=True)
response = c.get('/auction/add/') # get a fresh form
print(response.content) # just to have a look
csrf_token = response.context['csrf_token'] # get the token
print('the token is: %s' % csrf_token) # show me the token

# now, we add the token value to the key csrfmiddlewaretoken
# as this is where django CSRF will check it

post_data = {
'csrfmiddlewaretoken': csrf_token,
'item': 'test item',
'price': '154.78',
'end_date': '2011-08-05 19:30:00',
}
# now we can send the post
response = c.post('/auction/add/', post_data)
# now we test the assert
self.assertEqual(response.status_code, 200)

As I said, this still does not work, I get a 403: which refers
to an invalid CSRF token key. If you managed to overcome this
problem, please let us know. So far, I decided
not to use c = Client(enforce_csrf_checks=True) but this is not
a nice solution, is it?
Best!

Then I strongly suggest you take some time learning Python. I mean,
pure Python, without Django.

Knowledge comes from experience, and experience comes from practice.
Until you get some hands-on experience with both Python and Django,
your "research" is mostly a waste of time. FWIW, Django is pretty well
documented, and if you

1/ have some working experience with web programming (say, raw PHP /
MySQL, or CGI, or whatever) and
2/ do the tutorial

then you should know enough to start writing your app. Possibly not
the best way, but it still should work, and you'll learn how to
rewrite your app in better way in the process.

> Is the only way I am able to display a table from the

> to the template?

You don't even need a template - you can build the response content
how you see fit. Templates are just handy for most text (including
HTML) formatting, but that's all. And you (usually) don't "import data
to the template", you *pass* data (well, actually, python objects,
which is not quite the same thing) to the template, render it and
build a response from the result.


> Is there a another/better approach towards displaying
> a MySQL table in the Django app?

Django is not server page, it's a Model/Presentation framework. The
request/response cycle goes like:

1/ the framework finds an view matching the url pattern
2/ it calls the view with the request and possibly a couple arguments
computed from the url and the pattern
3/ the view returns a response

And that's it. The templating system is just here to help you
formatting your response's body.

Ok, it's half truth and half lie - using custom tags and context
processors you can do much more than "formatting data" with Django's
template system -, but still, Django is NOTHING like server page
systems (PHP, ASP 1.x etc), and the very core of Django is url
patterns matching, views, requests and responses. If you hope to make
the best use of Django, first learn to do things the Django way
instead of fighting against it. Trying to write PHP / ASP / whatever
server page system in Django will  be at best a very frustrating
experience.

This being said: template-driven code is *sometimes* just the
RightThing to do, and this is something you can indeed do in Django
(if you know how to) - but I don't think it's how you will better
solve your problem. FWIW, Django already has some support foer very
generic "table display / filter / search" features in the admin app,
and this is NOT template-driven code (but it's OSS so you can read the
source - but beware, serious Python knowledge required).

ModelAdmin, custom field: default value?

[momo2k]

Hello,

Is there a way to set dynamic default values for custom fields in the
admin?

Description of the problem:

# models.py
# there are two models
class Meal(models.Model):
name = ...

def check_new_price(self, price):
# checks if the price is new and creates a new price if
neccessary

class Price(models.Model):
meal = models.ForeignKey(Meal, )
valid_to = models.DateField() # None for current price
amount = CurrencyField() # nearly identical to IntegerField

# admin.py
# I extended the Admin with a custom form:
class MealModelForm(forms.ModelForm):
price = CurrencyFormField() # Nearly identical to Decimalfield
class Meta:
model = Meal

class MealAdmin(admin.ModelAdmin):
form = MealModelForm

def save_model(self, request, obj, form, change):
super(MealAdmin, self).save_model(request, obj, form, change)
obj.check_new_price(form.cleaned_data['price'])


My question is: How do i tell the django admin to display the current
price in the form field? I already tried to add an "price"-attribute
in the ModelAdmin.get_object() method, but that doesn't work. If I
call the Admin page for a meal, the price is blank instead of
displaying the current price.

So, repeating my first question: Is there a way to set dynamic default
values for custom fields in the admin?

OMG :(

Ok, you firts have to learn what a *relational* database is all
about.  The poll tutorial migh be a good starting point : a "poll" is
a question with a set of possible answers, and your "questionnaire" is
a set of questions with each a set of possible answers (do you notice
some pattern here ?)

You model should look something  like this:

class Questionnaire(models.Model):
title = models.CharField(verbose_name="Title", max_length=50)
description = models.TextField(verbose_name="Description",
blank=True, default="")
date_created = models.DateTimeField(auto_now_add=True)

class Question(models.Model):
questionnaire = models.ForeignKey(Questionnaire)
question = models.CharField(verbose_name="Question",
max_length="255")
help = models.TextField(verbose_name="Help", blank=True,
default="")

class Choice(models.Model):
question = models.ForeignKey(Question)
text = model.CharField(verbose_name="Text", max_length="255")

class Answer(models.Model):
user = models.ForeignKey(User) # or IP address or any other
session identifier
choice = models.ForeignKey(Question)


Notice how I didn't hard-code anything. All questionnaires /
questions / choices / answers are stored in the database, which means
you can create has many different questionnaires as you want without
having to write a single line of code.

Question about Displaying a Table

[Kyle Latham]

Hello,

I am pretty new to Django and Python.

I'm wanting to create a Django app that displays different tables in
my MySQL database, and the user can search through the tables for info
they want.

I haven't written any code yet, I'm doing research on the approach I
have to take.  Is the only way I am able to display a table from the
MySQL database in Django by creating a template and importing the data
to the template? Is there a another/better approach towards displaying
a MySQL table in the Django app?

Thank you,

Kyle

Re: Serving static/dynamic files under same suburl

[Mick]

Nginx can test to see if a file is available, and if it exist load that instead 
of proxying the request to django.


location / {
alias /var/www/static/;
if (!-f $request_filename) {
proxy_pass http://127.0.0.1:8000;
}
}


Now if /var/www/static/foo.js exists, but /var/www/static/bar.js does not 
foo.js will be served as a static file by nginx and the bar.js request will be 
passed to django where you can use a template to dynamically serve it.

Re: Serving static/dynamic files under same suburl

[Jani Tiainen]

Apparently I didn't made myself clear enough.

So let me clarify:

I have two files that must be accessed using following urls:

/myapp/views/foo.js
/myapp/views/bar.js

foo.js is a static file and can (and should) be served by using static
serving, like webserver.

bar.js instead is a file that contains django template directives and
must be served through django template rendering mechanism.

Re: Serving static/dynamic files under same suburl

[Shawn Milochik]

This can (and probably should) be handled by your Web server.

For example, in nginx you may be serving the Django app with something 
like this:


location / {
proxy_pass http://127.0.0.1:8400;
}

And for static content nginx may direct the request elsewhere. This 
example directs

any requests ending in '.html' to a static folder.

location ~ ^/.*\.html{
root /var/www/my_static_content;
}

Django-utils @async decorator and gunicorn

[Anton Pirker]

Hello! 

I use djutils [1] @async decorator for calling a function asynchronous. This 
works well when i start my server with the standard ./manage.py runserver 
command. But when i run my django app under gunicorn and i call the function 
with the @async decorator nothing happens at all... 

Do i have to configure djutils or gunicorn in a special way so i can run 
function asynchronous? 

Any hints are greatly appreciated! 

Thank's

Serving static/dynamic files under same suburl

[Jani Tiainen]

For example ExtJS 4 introduced new MVC app model. One of the features
and slight drawback is quite strict directory structure.

Now in most cases I can put files as static but there are occassions
when I would like to leverage power of Django templates, namely some
translations and urls

So for example in following structure:

/myapp/
/myapp/model/
/myapp/view/
/myapp/store/
/myapp/controller/

There is some (but not necessarily all) (javascript) files inside /
myapp/store/ and /myapp/view/ that I would like to load through
template rendering, specially "stores" part since it contains urls
that should point to views in my Django app and url config.

Same applies for some other files since I would like to use
translation facilities of Django.

In pseudo code I would like to do something like this:

Load static file from given url. (this would be handled by frontend
webserver in production)
If load failed:
Load dynamic file from templates dir
If load failed:
Raise error

Re: Importing file to Models - Temporary store to allow confirming?

[Victor Hooi]

Shawn,

Thanks for the quick reply =).

If we go with the third approach, what advantages are there to persisting
the models in MongoDB (or something similar like Redid.or Cassandra), as
opposed to a traditional RDBMS? (I just want to get a good handle on the
issues).

Furthermore, is there a particular reason you picked MongoDB over the other
NoSQL solutions?

Also, in terms of actually persisting the temporary models to MongoDB, I can
just use PyMongo and store the dicts themselves - and just user a nested
dict to represent all the model instances from a given import file. Any
issues with that approach?

Thanks for the tip about using asynchronous processing for the import file -
I didn't think the file would be that big/complex to process, but I suppose
it's probably the better approach to do it all asynchronously, instead of
just hoping it won't grow larger I the future. In this case, I suppose I can
just use Ajax on the page itself to check on the status of the queue?

Cheers,
Victor

Info and warning messages in admin

[Daniele Procida]

I need to be able to distinguish between info and warning messages that get 
passed to the user in admin.

I do this, and it works:

# import the admin messages framework
from django.contrib import admin, messages

class SomeForm(forms.ModelForm):
...
def clean(self):
# create a pair of empty lists for warning and information messages
SomeForm.warnings = []
SomeForm.info = []
... # do some things that add messages to the lists, based on
# things in cleaned_data
return self.cleaned_data

class SomeAdmin(admin.ModelAdmin):
...
def save_model(self, request, obj, form, change):
# loop over the lists of messages, and pass them to the messages system
for message in self.form.warnings:
messages.warning(request, message)
for message in self.form.info:
messages.info(request, message)
return super(SomeAdmin, self).save_model(request, obj, form, change)

This way yellow info messges get a little tick icon, while warnings have a 
warning sign (and really, ought to come up in orange, not yellow).

Is this a good or correct way of doing it?

Thanks for any advice or suggestions.

Daniele

... and I've just re-read your original message, and realized that
you've already done this.

/me looks sheepish

So, If DEBUG = False, and SEND_BROKEN_LINK_EMAILS = True, then you
should be getting emails on 404s.

Trying to think of some other reasons you might not be getting error emails...

You wont be getting 500 emails if:
 * you have a custom 500 handler, or
 * if DEBUG_PROPAGATE_EXCEPTIONS is enabled

You won't be getting 404 messages if
 * the common middleware isn't enabled
 * the URLs you're hitting match the values in IGNORABLE_404_STARTS,
IGNORABLE_404_ENDS or IGNORABLE_404_URLS
 * Your user agent isn't settings a HTTP_REFERER header
 * Your user agent hasn't got a HTTP_REFERER header that matches the
domain of your server

Hope this is slightly more helpful than my last two attempts...

Yours,
Russ Magee %-)

I think you've identified the problem. You have
'question.views.details' as your view function, but you haven't
supplied the source for it. Which I believe means you _have_ to write
it, and the template that goes with it.

One thing I would add: from a user-friendliness point of view, it
might be better to have the questions in one page, or at most 5.
Hitting "Next" 21 times is a turn off for most people. But you know
your needs best.

Best regards,
Peter

My apologies -- I didn't register that you were using connecting
directly to GMail's servers to send mail.

You haven't provided your mail settings, so it's impossible to know
exactly what is going wrong, but my best guess would be that you don't
have the EMAIL_USE_TLS setting enabled. GMail's servers use TLS to
provide on-the-wire security, but Django has this turned off by
default (since most mail servers don't enable TLS by default).

As far as debugging this problem goes -- my advice would be to start
lower in the stack. I can guarantee that if your email configuration
is right, then 404 mails will be sent -- the real issue is whether the
email configuration is correct. To verify this, use the mail APIs
directly. From a Python prompt on your sever:

>>> from django.core import mail
>>> mail.send_mail("A subject", "This is the message", "m...@example.com", 
>>> ["recipi...@example.com"])

substituting "m...@example.com" with your own address, and
"recipi...@example.com" with another email address you can test with.
This call should return 1, indicating that 1 email was sent. If it
doesn't, or it raises an error, you should get some indication of what
has gone wrong.

Re: questionnaire

[Cal Leeming [Simplicity Media Ltd]]

Hi Coulson,

Okay, I'll give you some feedback as to the code you have written below:

   - The design below means that the actual questions are assigned to a
   fixed column in the database, this is *NOT* good. You want to be using a
   'normalized' approach, by having the questions for the poll in
   a separate table, then the answers/session stored in another.

   By using the above, the code then becomes "reusable" and easily
   maintainable.

   - Good use of string formatting (using %s rather than string concat).


Hope this helps.

Cal

Re: Sidebars

[Cal Leeming [Simplicity Media Ltd]]

Can I just clarify what you mean by sidebar?

I assume you are talking about a html element with some options inside it,
to allow you to navigate through the site?

This is (personally) how I'd do it, although others may prefer a different
style (you could probably go as far to make this whole thing "classy").

(hand typed code, may need re-writing)

--- views.py ---
page = "dashboard/help/users"

RequestContext(request, {
'section' : page.split("/")
}

--- layout.html ---
{% if section.0 = 'dashboard' %}
display stuff relating to dashboard only
{% if section.1 = 'help' %}
display stuff relating to dashboard/help only
{% endif %}
{% endif %}

Django-utils @async decorator and gunicorn

[Anton Pirker]

Hello!

I use djutils [1] @async decorator for calling a function asynchronous. 
This works well when i start my server with the standard ./manage.py 
runserver command. But when i run my django app under gunicorn and i 
call the function with the @async decorator nothing happens at all...


Do i have to configure djutils or gunicorn in a special way so i can run 
function asynchronous?


Any hints are greatly appreciated!

Thank's
Anton

parametric class-based form views

[omat]

Hi all,

I am trying to use generic CreateView class to handle forms for a set
of models inherited from the same base class.

class BaseContent(models.Model):
...

class XContent(BaseContent):
...

class YContent(BaseContent):
...

To keep things DRY, I want to define one CreateView class that will
handle all inherited classes from BaseContent.

The url pattern for that view is:

url(r'^content/add/(?P\w+)/$',
ContentCreateView.as_view(), name='content_add')

Something like this should work:

class ContentCreateView(CreateView):
template_name = 'content_form.html'

def get_model(self, request):
# 'content' is the name of the application; model_name is
'xcontent', 'ycontent', ...
return ContentType.objects.get_by_natural_key('content',
self.model_name)

But I am getting this exception:

ContentCreateView is missing a queryset. Define
ContentCreateView.model, ContentCreateView.queryset, or override
ContentCreateView.get_object().

This suggestion does not seem to hold as I am not willing to set a
class attribute like `model` or `queryset` to keep the model form
generated dynamic. Overriding the `get_object` does not seem relevant
for creating an object.

I tried overriding `get_queryset()` but this method does not accept
the `request` parameter, nor have access to `self.model_name` which
comes from the url pattern.

So, (how) can I make a CreateView use a dynamic form based on a
parameter passed from the url?

Thanks,
oMat

Coulson,

That's probably the best advice you are going to get. You're going to
have to do it yourself - dive into HTML and get cracking. This list is
about Django, a Web framework written in Python. You're question is so
broad that it sounds like you're asking people to _design_ the whole
website for you. That may not be what you intended to convey, but
that's what it feels like.

If you intent to do your website through Django, please try to
research it as much as possible yourself. Then if your come across an
issue than you can't resolve, please have a read of this before
replying to the list:

http://www.mikeash.com/getting_answers.html

I'd also give some personal advice. It's harder to understand people
when they leave out punctuation. Periods and commas make your meaning
more clear, which makes other people more able to help you.

Best regards,
Peter

It looks to me like form.is_valid() is returning False, so you're seeing the

You can debug the cause by putting

import pdb;pdb.set_trace()

just above the "if form.is_valid():" line and then stepping through the
validation code in the debugger.

How to link custom search with a view in a different app ?

[Satyajit Sarangi]

# Create your views here.

from shapes.models import *
from openmaps.models import *


from django.shortcuts import render_to_response
from django.contrib.gis.shortcuts import render_to_kml
from openmaps.models import Open_Layers
from django import forms
from openmaps.forms import GeoForm
from django.contrib.gis.geos import  GeometryCollection,
MultiPolygon,  Polygon
from openmaps.forms import ReadOnlyForm
from django.shortcuts import get_object_or_404, render_to_response
from django.http import HttpResponseRedirect, HttpResponse
from mapsearch.forms import SearchForm
from OsmMap.models import OsmLayers
from maps.models import Sdr_Layer

def map_search(request):
 lcount = Open_Layers.objects.all()

 form = SearchForm()
 if request.method == 'POST':
form = SearchForm(request.POST)
if form.is_valid():
data = form.cleaned_data
val=form.cleaned_data['LayerName']

a=OsmLayers()
b=Open_Layers()
c=Sdr_Layer()
data = []
data1=[]
data2=[]
data3=[]
data1 = 
OsmLayers.objects.filter(Layername__icontains=val)
data2 = 
Open_Layers.objects.filter(Layer_name__icontains=val)
data3 = 
Sdr_Layer.objects.filter(layer_name__icontains=val)
data.append(data1)
data.append(data2)
data.append(data3)

return render_to_response('searchresult.html', 
{'data':data})



else:
form = SearchForm()
 else:
return render_to_response('mapsearch.html', {'form':form})


This is my view that returns the search data to searchresult.html .
>From searchresult.html , all the returned data , when clicked on
should take it to a view called map_disp directly from the template .

I have read through the documentation , and this is what I inferred .

1. Pass the primary key id as a number to the map_disp view and then
use it to retrieve the date .
2. Change the urls.py so that the number is captured .

Where my doubt is this , what changes needs to be done in the view
code that I have shown here so that the number is sent .

Custom Admin Login Page

[Thomas Guettler]

Hi,

settings.LOGIN_URL get's ignored by the admin app.

I don't want two login forms, but only one.

But I couldn't find a way to redirect to my custom login form
from the admin pages.

The only solution I found was a HTML redirect like this
  http://redirect-url;>

Anyone else who has this problem, or a solution?

  Thomas
