Specifically, what's the equivalent of this block:



def vote(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
try:
selected_choice = p.choice_set.get(pk=request.POST['choice'])

return render_to_response('polls/detail.html', {
'poll': p,

}, context_instance=RequestContext(request))
else:
selected_choice.votes += 1
selected_choice.save()
# Always return an HttpResponseRedirect after successfully dealing

return HttpResponseRedirect(reverse('polls.views.results',
args=(p.id,)))

Re: Question about threading a view[REPOSTED]

[Jani Tiainen]

Hi,

Basic idea is to send a message to message broker from your view to tell "I
want to run this long running task X".

After that your view can return (with task id). After that your client can
start asking from second view for long running response.

In the background you have to have some means to query message broker for
requested tasks and execute them. For example
using a cron job.

That's where django-celery comes in. It can create tasks and it can run
tasks within Django framework using various message
brokers - rabbitmq being probably most popular.

So first you define task with django-celery. Then in your view you send
message to message broker that "execute that task".
And then you must have some background running process to read messages
from broker and execute them.

What comes to testing usually you mock responses in these kind of tests. Of
course you can still test your long running process but
in unit tests you don't test that communication between broker and running
system.

HTH,

Jani Tiainen

Re: Question about threading a view[REPOSTED]

[Arruda]

Some one also gave me that tip. 
I was reading it, but I couldn't see much clear how to use this in this 
case.
I saw that to execute a task I should run it by using ./manage.py ... and 
how can I do that in a view?
Another thing is that it seems to me a bit overkill isn't it, and a little 
to complicated to setup.
To test it in development I need to prepare a huge scenario so that it can 
work out, and also I can't imagine how to use this in tests. 

Did I understood it wrong? Ins't it a lot complicated to use?

Thanks

Django 1.4 => [ Python2.5, Python2.6, Python2.7 ]
Django 1.5 maybe=>  [Python2.5+,  Python3.3]

Actually python2.7 is the best solution to begin, if you like the syntax of
python 3x you can use import __future__

Re: calculated form field

[Tim Ney]

Rajeesh,

Following your advice, Im think I've about solved the problem.
I've got one last exception, I hope.

Here is the new iteration of views.py, all other files remain the same.
In short the page renders to the screen, the problem arises when values are
submitted
to the view.

I get an exception  "can't multiply sequence by non-int of type 'tuple".
I've created a new
function that describes the multiplication operation, that is used within
the render function, this
is where the error occcrs. I'm not referencing the variables properly, I
guess.

def calculation(request):
 """function that computes submission"""
if request.method == 'POST':
 form = FinanceTable(request.POST)
 if form.is_valid():
   cd =form.cleaned_data
   capital = cd['capital'],
   tax_rate = cd['tax_rate'],
   useage = projfin(request, capital, tax_rate)
   response_dict = {'capital' : capital, 'tax_rate' : tax_rate,
'useage' : useage}
   return render_to_response('textplusnumbers.html' , response_dict)
   else:
 form = FinanceTable(
  initial={'capital' : 1000, 'tax_rate' : .07}
  )

   return render_to_response('textplusnumbers.html' , {'form' : form})

def projfin(request, capital, tax_rate):
 useage = capital * tax_rate
 return useage

Need advice on admin models

[django_noob]

Hello all, 

I am just starting learning Django and managed to get a basic website 
working with a nice admin section. I am now facing a problem which I am not 
sure how to resolve. 

So I basically have 2 tables in my database: 
- Flat 
- PendingFlat 

The PendingFlat would be a subset of the Flat table. 

The website will offer the ability to a user to sell his flat. The website 
will ask only a few questions to the user such as the price and the 
location and store this information within the PendingFlat table. The admin 
can then go the admin section of the website, view all pending flats from 
the PendingFlat table and approve them as he wish. So I'd like to have an 
approve button next to each line of the records of the PendingFlat table. 
This button should then get the admin to the add view page of the Flat 
table with some prepopulated fields such as the location and the price. 

My first attempt was to do the following in the admin.py file: 
class PendingFlatAdmin(admin.ModelAdmin): 
def button(self, obj): 
return mark_safe('Approve'.format(obj=obj)) 
button.short_description = 'Approve' 
button.allow_tags = True 
list_display = ('id', 'button') 
admin.site.register(PendingFlat, PendingFlatAdmin) 

This will successfully get the admin to the add flat page with the rent 
being prepopulated. Unfortunately, this won't delete the PendingFlat entry 
once the admin has successfully added this flat to the database and it also 
makes it difficult to maintain when new attributes are being added to the 
table. Is there a nice way to achieve this? 

I understand that my choice of database structure might be wrong. It might 
be better to have a single table Flat which has a pending boolean field. 
But if I do this how can I mark certain felds as being optional (blank = 
True) when the pending field is set to True? 

Thanks, 
a noob who hopes to lose his noob status as soon as possible [image: :)]

Question about threading a view[REPOSTED]

[Arruda]

*(I've created a topic like this a few minutes ago, but was using the old 
google groups, and now it's broken. So I created a new one using the new 
google groups).*
Hi, I'll try to explain the best I can my problem, and I don't know if
what I'm trying to archive is the best way to get where I want, but
here is it:
I want that a specific view to run in a new thread, ex:
* def foo(request):
   do_something_slow()
  return httpResponse*

But I DON'T want that a new thread is run inside the view, the view it
self should be runned in another thread, ex:
*
 def foo(request):
   t = thread(target=do_something_slow())
   t.daemon = True
   t.start()

  return httpResponse
*
This way when a user A access any page the site will load, even if a
user B is accessing the 'foo' view.
But the B user when access the view 'foo' will load it just a if if
was a normal view( will be slow and will render the response just
after do_something_slow() finished running).

I don't know if this is what I want, but I believe that there is
another way around:
when user B calls foo view, it will render to him a page with a JS(I
don't know JS either, so correct me if I'm talking nonsense) that say
its "Loading..."
And after the do_someting_slow() finished running if will change the
content of the page to whatever the result of "do_something_slow" was.

Thanks for the attention.

Custom template tag - share data

[mikegolf]

Hi,
lets say I want my templatetag to collect menu items from all the
rendered template pieces.

I thought of writing custom templatetag which would work as following:

this would be called in "sub-template"
{% register_menu_item "some item" "/someItem/view" %}

and finally the "main" template would call {% render_menu %}

the first command would simply add the (label, url) to the collection,
the second one would render all the collected items.

The problem is - where to keep the collected data? the RequestContext
passed is not always the same, even during processing the same request.

[Rajeesh Nair]

Add a field on your model to identify the user who created each instance & 
then extend your model_admin's queryset method to filter queryset by the 
user.

Re: Problem with tuncated Admin pages in apache + mod_fcgid

[Jani Tiainen]

Hi,

Since we use same setup except one part: we use mod_wsgi instead of
mod_fcgi.

(Since wsgi is considered to be defacto protocol). Could you try to use it?

Re: starting django

[Willy]

If you're learning Django and Python I think you're missing some
prerequisite knowledge. I would really suggest you learn how to
install both Python and Django on your own as well as working through
this tutorial on Python so that you have at least a basic
understanding of the language. http://docs.python.org/tutorial/index.html

That way you're better prepared to learn Django as Django is just
Python code.

Roberto,

Thank you for cheering me up : ) Like I said gevent-fastcgi is not
suitable for every project and I don't expect people switching to it
en masse but those who needs what it provides should benefit from
using it. I know that mainstream Web-servers do not support FastCGI
multiplexing or support for it is buggy. That is sad since it doesn't
cost much to implement and it could be a big deal in fight against
C10K problem. I saw something like "there are not many FastCGI servers
that support multiplexing so why bother to implement that in our Web
server" while I was looking for Web-servers that do multiplexing.
Hopefully, Web-server developers will have little less excuses to not
implement it.

I haven't tested FastCGI multiplexing feature because I couldn't find
Web-server that supports it out-of-the-box. However, I found reference
to alternative Nginx FastCGI module that supposedly designed to
support multiplexing (https://github.com/rsms/afcgi). Also Cherokee
Web-server had another version of FastCGI module with connection
multiplexing (http://code.google.com/p/cherokee/issues/detail?id=714).
Rumors have it Zeus Web-server has FastCGI multiplexing feature but
it's not available for free.

Caching and module import question

[Jeff Heard]

Question 1: Would this work with views, or for that matter, anything else
in Django, assuming you're using a WSGI server like gunicorn?
http://code.activestate.com/recipes/578078/  Specifically, will it cache
across HTTP requests, or not?

I guess the one thing I don't understand well in Django is when modules are
re-loaded.  I know it's different in a "full-fledged" setup vs. the test
server, but is there a rule one can follow? Is it different on WSGI vs.
FastCGI? And finally, if I delete a module from sys.modules, does that
effectively delete it from the cache or is there something else I need to
do to make sure it's reloaded the next time someone makes a request?  I
would assume that deleting the module from sys.modules would only delete it
from one worker process.

Re: calculated form field

[Rajeesh Nair]

Your FormClass expects all 3 fields to be optional (*required=False*). But 
your code in view always expects them to have integer values. And you end 
up multiplying values from two blank fields! Either you provide some 
default value to the fields or rewrite view to use *form.cleaned_data.get*with 
a default value as 2nd argument to it.

Re: calculated form field

[Tim Ney]

Thank you for responding, this is a vexing problem.
I know the urs.py is fine, as the the form html code I posted
is part of an .html, largely static html, which renders to the screen fine.
The form fields are also showing up in the rendered page, and numbers can be
entered, when the submit button is clicked I get the exception

Did I not understand your question, I am new at this.

Re: Models, field like a list

[Jani Tiainen]

Hi,

All depends on a few factors will simple foreign key or many to many be
correct solution.

If single model B can be assigned only on a single model A then foreign key
from B to A is right choice. But if
requirement is that model B can be assigned multiple times to model A then
it's definitely many to many.

And that's pretty much how far you can get with traditional RDBMS. You can
easily write convenience
methods/properties on a model class to cut out few corners if needed.

Of course you can go in many other ways, for example storing primary key
values as a string list, and then parsing it.
It's just not good thing to do. You can easily end up with data integrity
problems like what should happen if you delete
entity from model B? or your list in model A doesn't find all entities in
model B.

What does your urls.py file look like.  If you are getting 404 then it
may not be finding your view.

So your other choice is whether to go with django 1.3 or the new 1.4
being released some time in the coming days.  Probably best to go with
1.4 since they keep making it better, but there are differences
between the new version and the old version's way of setting up
directories, so beware that third party tutorials will have to be
tweeked with to get going in 1.4

Re: New way to run your Django projects

[Kurtis Mullins]

Sorry, I didn't mean to sound like I was putting down your application. I
think it's a great thing to develop more applications. I can't wait to see
the progress you make :)

I was just trying to clarify that these days, stock Nginx does provide WSGI
in its default configuration. Of course, I didn't think about specific
distributions offering alternative or older configurations of Nginx.
Running 'sudo apt-get install nginx' is a bit easier than './configure;
make; sudo make install' -- especially with the distribution's
initialization scripts -- but I'm a bit old school when it comes to that.

One thing I can say about FastCGI (the reason I don't develop with it) is
that it's licensed under the OpenMarket License which is, to my knowledge,
not compatible with GPL. However, that's the libraries and not the raw
protocol itself.

Good luck and happy hacking!

calculated form field

[bolivar4]

Want to present users a form in which numbers are entered, then manipulated 
in a view and a calculated value is returned to the screen.
After looking in the the Django book around the net this is what I have 
come, (it doesn't work) shows below.  So far, the three fields setup in 
forms.py render to the secreen, that is all I'm getting. 

 

I am getting this error in the django 404 exception page: "unsupported operand 
type(s) for *: 'NoneType' and 'NoneType'"

 
It is purposely a  simple exercise, more interested  in technique of doing 
this so, I know this can be done in javascript, but I want to do this with 
python/django.
Thank you to anyone who can help me out, this has been a problem all 
weekend.
 
forms.py:
 
from django import forms
 
class FinanceTable(forms.Form):
   capital = forms.IntegerField(required=False)
   tax_rate = forms.DecimalField(required=False)
   useage = forms.IntegerField(required=False)
 
views.py:
 
from django.shortcuts import render_to_response
 
def  calculation(request):
   """view that sets up form calculation"""
   if request.method == 'POST':
form  = FinanceTable(request.POST)
if form.is_valid():
 capital = form.cleaned_data['capital']
  tax_rate = form.cleaned_data['tax_rate']
  useage = form.cleaned_data['capital'] * 
form.cleaned_data['tax_rate']  
  response_dict = {'capital' : capital, 'tax_rate'  : 
tax_rate, 'useage' : useage}
  return render_to_response('focus_areas.html', 
response_dict)
else:
  form = FinanceTable(
 initial={'capital' : 1000, tax_rate : .07}
   )
return render_to_response('focus_areas.html', {'form' : form})

Django/Python version compatibility

[Chiproller]

I am just learning Python and plan to use it for web development so I
will be using Django.  Python version 2.7 was pre-installed on my
macbook and I'm wondering if I installed the latest 3.* version would
Django not work at all when I get to the point of learning Django?

Reason I ask, is that I'm using a number of resources to learn Python
(Learning Python, Programming Python, Learn Python the Hard Way) and
some of these books use 3.0 code.

Hi Alexander,
Thanks for your long response, really apreciate it.
Actually, i'm just django & python beginner, although already have a few 
simple sites in production.


And actually i'm not really understand wsgi, uwsgi, etc.
I use nginx because AFAIK it great on serving static files and as a proxy.
I use gunicorn when i need multiple process.

When will i need your gevent-fastcgi? Or which types of applications 
that really need your gevent-fastcgi. From your answer, one of them is 
long-polling webapp and webapp with thousand of simultaneous connections.

As a newbie, i think i will not build that kind of advanced apps now.

Thanks



As to comparing Gunicorn to gevent-fastcgi Gunocorn is HTTP server and
gevent-fastcg is FastCGI one. FastCGI can run over UNIX domain
sockets, it can multiplex requests using single connection. That could
be deal-breaker when application is using long-polling requests and
there are thousands of clients that can be accessing it
simultaneously. Beside HTTP is not well suited for communication
between frontend and backend (just recall famous need to fix
hostname:port in backend server responses because backend server has
no way to get access to original HTTP-request and it might not even
know that there is something that makes request on behalf of client
browser). There is no such problems in FastCGI protocol because it was
specifically designed for frontend/backend communication.

Gevent-fastcgi is not well suited for any type of applications. The
application should not block since everything is run in the same
thread (there are greenlets that are used in place of thread to avoid
GIL). Not all databases and other external resources can be used in
non-blocking mode. Luckily PostgreSQL, MySQL, Memcache are those that
have adapters/hooks for making them work well in non-blocking manner.

Re: New way to run your Django projects

[Carlos Daniel Ruvalcaba Valenzuela]

I think it is an interesting project, many may say its pointless given
the "wealth" of wsgi servers, but I think there is always space to
explore more, who says this project can't be faster than many of
today's servers?, or who says there wont be anything useful out of
this project even if is not really popular as gunicorn or uwsgi? I
imagine uwsgi started this way against the "mainstream" apache
mod_wsgi, but now uwsgi has more features, its fast and it has been
adopted as a sort of defacto wsgi module by nginx, who says a new
project can't be done?

Keep it up, I will personally give it a try!

Re: Models, field like a list

[Dmitry Zimnukhov]

Hi,
If you want to retrieve list of related models with one to many
relation, you can do it with related manager, without adding a field
to model A.
So, if you have model B like this:

class B(models.Model):
 a = models.ForeignKey(A)

you can get related B objects like this: a_instance.b_set.all()

But if you want to have an array field in your model (so that array
data will be stored in the same table that stores model data), your db
backend must support it and you must extend Django to support this
functionality. That's probably not what you want.

Yes, but when you release a software, be prepared to answer the most useless, 
provocative
and rageous questions :) Expecially if your project is pretty 'unique'.

You are lucky (for now), the questions you got are all 'gentle' :)

Your project is really funny, but you will need to fight with two factors:

few users/developers understand non-blocking/async programming (albeit a lot of 
them use, and blindly suggest, such technologies)

webservers support for multipexing fastcgi requests is practically non-existent 
or buggy, on which webserver you have tested your project ?

In addition to this, Django is not the kind of framework/platform you can - 
easily - adapt to non-blocking/async paradigm :(

Kurtis,

There is nothing wrong with using uwsgi protocol instead of FastCGI
but you still have to run uWSGI server and it doesn't fit "simply
using nginx" description. And I wouldn't call it "out of the box"
either if I'd have to rebuild Nginx instead of using one shipped with
my Linux distro (Debian Squeeze has Nginx with uwsgi module in

I didn't say gevent-fastcgi is best way to run WSGI application.

I use Nginx w/ WSGI (Django running under uWSGI, communicating w/ WSGI

Re: Combining two model fields into one

[Kurtis Mullins]

Sorry, I kind of left you some misleading information.

The LocalFlavor stuff are *Form* fields (not Model Fields). And, they are
specific to certain countries so it may not work for you if your
application supports multiple countries. It could be a good starting point
for your own custom form field, though. They do include telephone numbers.
Judging by the django developer's choice to put that logic in Form Fields
instead of Model Fields, it may be a good idea (or at least easier) to
follow their lead on doing it that way.

Re: Combining two model fields into one

[BGMaster]

That looks like it could work. The problem I'm having is tying into a
ModelForm. I want to create something basically to the effect of:

 phoneNumber = phoneNumber1+phoneNumber2

Here, phoneNumber1 and phoneNumber2 are the first 3 and last 4 digits
of a user's phone number. I want them input as separate fields for
sake of readability and then want to combine them into one model for
searchability in the database. Do you have an example of
MultiValueField? The django documentation isn't very clear on it.
Here's what I've been trying:

  class launchForm(ModelForm):
  phoneNumber = forms.MultiValueField(fields=[phoneNumber1(),
phoneNumber2()])

  class Meta:
model = potentialUser

Re: Trouble setting up website with mysql as backend

[Swaroop Shankar V]

Hello Clifford,
It was really nice of you to provide an insight into the non strict mode. I
agree to what you said regarding the length of the field. I was developing
the project using sqlite and since it was ready to go live i wanted to test
it using mysql in my local system. When i ran syncdb i was getting the
above said error and just for the sake of testing i changed the mode to non
strict. Am not planning the same for my production server. Once again
thanks a lot for your input. Cheers.

Thanks and Regards,

Swaroop Shankar V

Re: New way to run your Django projects

[Alexander]

Hi Bolang,

I'm not sure what you meant by "simply using nginx" since as far as I
know it doesn't have standard WSGI module. I hope you're not talking
about running WSGI application as CGI script, do you?

As to comparing Gunicorn to gevent-fastcgi Gunocorn is HTTP server and
gevent-fastcg is FastCGI one. FastCGI can run over UNIX domain
sockets, it can multiplex requests using single connection. That could
be deal-breaker when application is using long-polling requests and
there are thousands of clients that can be accessing it
simultaneously. Beside HTTP is not well suited for communication
between frontend and backend (just recall famous need to fix
hostname:port in backend server responses because backend server has
no way to get access to original HTTP-request and it might not even
know that there is something that makes request on behalf of client
browser). There is no such problems in FastCGI protocol because it was
specifically designed for frontend/backend communication.

Gevent-fastcgi is not well suited for any type of applications. The
application should not block since everything is run in the same
thread (there are greenlets that are used in place of thread to avoid
GIL). Not all databases and other external resources can be used in
non-blocking mode. Luckily PostgreSQL, MySQL, Memcache are those that
have adapters/hooks for making them work well in non-blocking manner.

Re: starting django

[Raphael Reumayr]

hello Kikozzza,

if you say ubuntu 10 I give a shot into the dark and tip on ubuntu
version 10_04 LTS (long term support).
After installation you can open a terminal an type:
python

the python console will open and responding with version Python 2.6.5 as
this is the default version on ubuntu 10.04

After your friend has installed django on your system - the version is
system independent, do the following:
again run the command "python" in terminal:
python
and then type
import django 
print django.VERSION

this could look similar to this approach:
Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41) 
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> print django.VERSION
(1, 2, 3, 'final', 0)
>>> 

so you see on this machine I am running Django version 1.2.3 final

Good luck on improving your skills!

from the shell just type python and you will enter they interactive
python shell.  The first thing it shows is the version of python

then type import django

then type help(django0) and look down through the information it
shows.  the version is near the bottom

It sounds to me like you might be looking for a django.forms.MultiValueField. 

The SplitDateTimeField is one example of a MultiValueField in action -- it uses 
two CharField inputs to capture the date and the time, then combines them into 
a single datetime object for the database. 

Yours,
Russ Magee %-)

Combining two model fields into one

[BGMaster]

Hi,

I'm trying to combine the values from two separate fields into one
field for my database model. I've tried this both in the view function
with the values passed back through POST as well as trying to write a
method for my model. Any suggestions on the best way to do this?
Basically, I just want to add a field to my model that combines a
phone number and area code field into one field for the database.

Thanks

Re: Running manage.py commands in Windows Power Shell

[orschiro]

After testing the Python distribution of ActiveState I have to confirm
that with that version I smoothly can run .\test.py in PowerShell
without having the cmd window to pop up.

Overall I can only recommend all Windows users to prefer this one over
the default one.

Re: VERY strange unicode encode error on internet connection

[ionic drive]

hello django friends,

issue found and solved.
The code which was causing the trouble:
log.debug('Using "%s" as title for "%s"' % (title, url))

as url is having a '/u' in the link this was causing the following error
message:
Caught UnicodeDecodeError while rendering: 'ascii' codec can't decode
byte 0xe2 in position 31: ordinal not in range(128)

I fixed this by doing a force to string conversion on url:
log.debug('Using "%s" as title for "%s"' % (title, str(url)))

I am not sure if this is a clean solution to the problem.

Kind regards,
ionic
