if you're going to use it a lot, you could create a wrapper function
that you only have to pass "request" to. For example;

def render_with_request(request, *args, **kwargs):
   return render_to_response(
   context_instance=RequestContext(request),
   *args, **kwargs)

However you might find you also have more stuff you do at the end of
every view and it might make sense to have some common "finalise"
function you call each time, instead of render_to_response().
Circumstances vary.

Malcolm

I think that every web designer should read this,

 http://www.owasp.org/index.php/OWASP_AppSec_FAQ

and to address this question specifically:

http://www.owasp.org/index.php/OWASP_AppSec_FAQ#How_can_my_.22Forgot_Password.22_feature_be_exploited.3F

and the following four questions and answers.  

In the end, it also says the same things as Russ does.

i have created a django project successfully and then create a

Don't. Ever. Do. This.

You should _never_ store passwords in cleartext, and you should
_never_ transmit passwords in cleartext. If you think I'm kidding,
read up on what happened to Reddit.

Directives are only allowed in .htaccess files if the main Apache
configuration has been set to allow them. It's possible that whoever
runs your server has not allowed the use of AddHandler in .htaccess,
so it is serving the file rather than running it.

Talk to your hosting company and see if this is the case, and if so
whether there are any alternatives that they support.

django forms - JSONRPC API - progress

2009-04-05 Thread lkcl

the basic plan is to provide a generic JSONRPC front-end to Django
forms which could conceivably become a de-facto interoperability
standard for web 2.0 applications to create, validate and store data
in "forms".

i've just added "describe" and "describe_errors".

http://pyjamas.svn.sourceforge.net/viewvc/pyjamas/trunk/pyjs/jsonrpc/django/jsonrpc.py?view=markup

the basic idea, as mentioned previously, is to allow an AJAX
application, using JSONRPC, to interact fully with Django Forms. i.e.
*without* forcing the server to generate some dumb bit of HTML which
you are forced to use, forced to perform HTTP POSTs on etc. etc.

now that "describe" has been added, the next step will be to create an
http://pyjs.org AJAX form "widget" that uses the "describe" command to
find out what fields to build into the form.

* CharField, FloatField, DecimalField etc. will result in a pyjamas
TextBox, with the option for a TextArea being a user-defined option.

* DateField, TimeField etc. will result in a calendar widget popping
up, there's one i've found at:
http://pyjamas-utils.googlecode.com/svn/trunk/examples/calendar/index.py

* FilePathField will be interesting because it implies a level of
interaction with the server: the most sensible widget to use here
would be a recursive / interactive Tree Widget that performs further
JSONRPC function calls to obtain subdirectory contents, on request.

exactly what these fields will go in to, and what CSS style names will
be attached to them, will be entirely up to the user, with sensible
defaults provided. a Grid seems the most sensible, with the names on
the left, and fields on the right, springs to mind, resulting in the
construction of something similar to the "as_table" method of Django
Forms. except pure AJAX. no HTML in sight.

interestingly, i can't find anything in Django Forms which tells you
how to specify "password" input boxes. also, RegexField's design
destroys the possibility for finding out what the regex is (in string
form), thus making it very difficult to perform client-side validation
(using the ECMAScript Regex object).

so there are a few hurdles yet to be overcome.

the above can also be implemented in GWT, using exactly the same
JSONRPC service, which is why i describe the API as being a de-facto
standard. in fact, if you were feeling particularly masochistic (i.e.
a PHP programmer) you could implement this in PHP, both client or
server.

anyone who would like to collaborate or contribute please do join the
pyjamas-dev list.

Deploying django application

Hi!

I am trying to serve my project using server-spawned processes

I created file .htaccess in my web_root directory which contains:
AddHandler fastcgi-script .fcgi
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ mysite.fcgi/$1 [QSA,L]

And also added file mysite.fcgi to same dir
#!/usr/bin/python
import sys, os

# Add a custom Python path.
sys.path.insert(0, "/home/user/python")

# Switch to the directory of your project. (Optional.)
# os.chdir("/home/user/myproject")

# Set the DJANGO_SETTINGS_MODULE environment variable.
os.environ['DJANGO_SETTINGS_MODULE'] = "myproject.settings"

from django.core.servers.fastcgi import runfastcgi
runfastcgi(method="threaded", daemonize="false")


But when trying to go to my domain http://goclub.org.ua/ I see the
contents of mysite.fcgi instead of my site...

The issue is that in a template, you can't call any method or function
that requires an argument. There are two ways of dealing with this:
create a custom template tag or filter, or create a method that
doesn't need arguments.

In this case, I'd go with the second option. Just create a method on
the Scientist model that returns a queryset of conferences at which
they are a presenter.

class Scientist(models.Model):
 blah 

def presenting_conferences(self):
return self.conferences_set.filter(presenter=True)
#or whatever the filter is

and in the template:

{% for conference in scientists.presenting_conferences %}
etc.

Re: Best JS Library compatibility for Django

2009-04-05 Thread Florian Strzelecki

Hm... look at this :
http://docs.djangoproject.com/en/dev/ref/request-response/#django.http.HttpRequest.is_ajax

HttpRequest.is_ajax()¶
New
in Django 1.0: *Please, see the release
notes*

Returns True if the request was made via an XMLHttpRequest, by checking the
HTTP_X_REQUESTED_WITH header for the string 'XMLHttpRequest'. The following
major JavaScript libraries all send this header:

   - jQuery
   - Dojo
   - MochiKit
   - MooTools
   - Prototype
   - YUI

If you write your own XMLHttpRequest call (on the browser side), you'll have
to set this header manually if you want is_ajax() to work.

Re: How can I filter query sets in a django template?

2009-04-05 Thread Florian Strzelecki

Did you try to look at Inclusion Tag ?
http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#inclusion-tags

In template you are not allowed to use some python code... but with an
inclusion tag, you will be able to write this :

{% load related_conferences %}
{% related_conferences scientist %}

And your inclusion tag may be this :

@register.inclusion_tag('path/to/tag/related_conferences.html')
def related_conferences(scientist):
# define here list_of_conferences
return {'list': list_of_conferences}

The inclusion tag have been created for this : move python code into python
file ! Not into template files.

I hope this will help you.
And sorry for my English, I'm french. :)

Django will work perfectly fine with any javascript library you choose to
use.  That being said I personally like jQuery because of its simple API.

It depends how you mean combine really. You can have them both running on
the same server, you can have them share the same database (then you can
still manage it with django)

Re: Form wizard - previous step


Do you have one view for each form or do you use one view with a large
amount of conditional logic (e.g. if stepone then show this form
elseif steptwo show this form)?

How can I filter query sets in a django template?


I posted a question earlier today about circular imports (http://
groups.google.com/group/django-users/t/6119e979131c8c25).  I now have
a follow question to that.  I've got the following view logic.

def portal(request):
scientist_id = 1
s = get_object_or_404(Scientist, pk=scientist_id)
return render_to_response('scientists/portal.html',
{'scientist':s})

Now, Scientists are related (many-to-many) to Conferences through
ConferenceAttendee.  Both of these models are created in a different
app.  I won't paste them in unless someone needs to see them in order
to answer my question.

I only want to loop through conferences that this scientist is
presenting.  (ConferenceAttendee.presenter=True).  I have tried
following the docs (http://docs.djangoproject.com/en/dev/topics/db/
queries/#field-lookups-intro), but it seems that you can only call the
filter method in python files like views.py or models.py.  I've tried
replacing the loop code below with "for ...conference._set.filter(...)
but python gives me errors when I do that.  Here is my template logic.

Your Presentations


{% for conference in scientist.conference_set.all %}

{{ conference.title }}
{% endfor %}



I've been stuck on this one for days now so any help would be greatly
appreciated.  Please do point me to any articles that I may have
missed that already answer this post.

Thank you,

Guy

Re: More beginner questions : model data in public view


Thanks again. Thats pretty much clear to every programmer i guess
(which im not - im just trying to figure out wtf are the programmers
at my work talking about).

Can you clarify me why these do not work :

def index(request):
lpl = lang.objects.get(id=1)
return render_to_response('front/index.html', {'lang': lpl })

def index(request):
lpl = get_object_or_404(lang, id=1)
return render_to_response('front/index.html', {'lang': lpl})

and this does

def index(request):
lpl = lang.objects.get(id=1)
t = loader.get_template('front/index.html')
c = Context({
'lpl': lpl
})
return HttpResponse(t.render(c))

since i get crap in public view, it seems there is something wrong
with getting the value of lpl..

You can run under Apache using either mod_python or mod_wsgi, start by
taking a look at their documentation:
http://docs.djangoproject.com/en/dev/howto/deployment/modpython/

What you want to do is combine these into one urlpattern:

from django.conf.urls.defaults import *

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
(r'^polls/$', 'mysite.polls.views.index'),
(r'^polls/(?P\d+)/$', 'mysite.polls.views.detail'),
(r'^polls/(?P\d+)/results/$', 'mysite.polls.views.results'),
(r'^polls/(?P\d+)/vote/$', 'mysite.polls.views.vote'),
(r'^admin/(.*)', admin.site.root),
)

Would be the end result.

Re: More beginner questions : model data in public view


Okay.. the problem was what i suspected, but i thought, that if i
filter the results and get object by its id, then it would be ok,
since im getting single object.

Your issue here is `lpl` is a QuerySet, not a lang object, when you want
more than one object you use .filter and then iterate over it using the for
tag.  However, when you want a single item you should ues .get(), so
lang.objects.get(id=1).

Absolutely.  Without seeing  your code I'd guess the problem is that you
only have the patterns from part 2 in your URLconf.  You need to make sure
you have the URLs from both parts in your URLconf.

Multiple Database in 1.0.2 with custom manager

2009-04-05 Thread Justin


I am trying to setup a custom manager to connect to another database
on the same server as my default mysql connection.  I have tried
following the examples here
http://groups.google.com/group/django-developers/browse_thread/thread/5d8c73eb483029af/19b19ed79bbbfa0d
and here 
http://www.djangrrl.com/view/multiple-database-connection-a-simple-use-case/
but have had no luck.  I get an empty tuple when returning
MyCustomModel.objects.all().

Here is what I have in manager.py
from django.db import models
from django.db.backends.mysql.base import DatabaseWrapper
from django.conf import settings

class CustomManager(models.Manager):
"""
This Manager lets you set the DATABASE_NAME on a per-model basis.
"""
def __init__(self, database_name, *args, **kwargs):
models.Manager.__init__(self, *args, **kwargs)
self.database_name = database_name

def get_query_set(self):
qs = models.Manager.get_query_set(self)
qs.query.connection = self.get_db_wrapper()
return qs

def get_db_wrapper(self):
# Monkeypatch the settings file. This is not thread-safe!
old_db_name = settings.DATABASE_NAME
settings.DATABASE_NAME = self.database_name
wrapper = DatabaseWrapper()
wrapper._cursor(settings)
settings.DATABASE_NAME = old_db_name
return wrapper

and here is what I have in models.py:

from django.db import models
from myproject.myapp.manager import CustomManager
class MyCustomModel(models.Model):
field1  = models.CharField(max_length=765)
attribute = models.CharField(max_length=765)

objects = CustomManager('custom_database_name')

class Meta:
abstract = True

But if I run MyCustomModel.objects.all() I get an empty list.

I am pretty new at this stuff so I am not sure if this works with
1.0.2, I am going to look into the Manager code to see if I can figure
it out but I am just wondering if I am doing something wrong here.

Thanks,
Justin

Re: Model A imports Model B imports Model A - I'm completely lost as to how to get around circular imports


Doug,

Thank you so much.  I completely missed that detail while ripping
through the django docs.  I've got it all working now.  Ramiro, thanks
again for your help.

For anyone else who is trying to do this and stumbles upon this
thread, here is my full final solution.

--- Overview ---
I've got two applications within the scinet project.
scinet.conferences and scinet.scientists  There are 4 files in all
that I need for this to work.  scinet.conferences.models.py,
scinet.scientists.models.py, scinet.scientists.views.py and
scinet.templates.scientists.portal.html

--- scinet.conferences.models (DjangoProjects/scinet/conferences/
models.py) ---

I define the many-to-many relationship between conferences and
scientists here.  A conference can be attended by multiple scientists
and a scientist can attend multiple conferences.  Do note that I have
arbitrarily chosen to use the Conference model to specify the
relationship between Conferences and Scientists.  I could have done
this in my scientist model just as well.  It is important to not that
I had to import the Scientist model here since I must reference it in
order to specify the relationship in the following line: scientists =
models.ManyToManyField(Scientist, through='ConferenceAttendee').

from django.db import models
from scinet.scientists.models import Scientist

class Conference(models.Model):
title = models.CharField(max_length=200)
description = models.TextField()
date = models.DateTimeField()
scientists = models.ManyToManyField(Scientist,
through='ConferenceAttendee')
created = models.DateTimeField()
modified = models.DateTimeField()

def __unicode__(self):
return self.name

class ConferenceAttendee(models.Model):
conference = models.ForeignKey(Conference)
scientist = models.ForeignKey(Scientist)
rsvp_date = models.DateTimeField()
presenter = models.BooleanField()

--- scinet.scientists.models (DjangoProjects/scinet/scientists/
models.py) ---

Here is where I define my Scientist model.  The point to note here is
that I do NOT need to reference the conference model because in
Django, I only need to define a relationship between two models in one
of the two models.  In fact, you must ONLY define the relationship
between two models in ONE of the two models.  DO NOT SPECIFY A
RELATIONSHIP BETWEEN TWO MODELS IN BOTH MODELS.

from django.db import models

class Scientist(models.Model):
user = models.ForeignKey('auth.User')
summary = models.TextField()
undergrad = models.CharField(max_length=50)
graduate = models.CharField(max_length=50)
post_doctorate = models.CharField(max_length=50)
current_employer = models.CharField(max_length=50)
zipcode = models.CharField(max_length=5)
city = models.CharField(max_length=50)
state = models.CharField(max_length=2)
country = models.CharField(max_length=200, blank=False)
created = models.DateTimeField()
modified = models.DateTimeField()

--- scinet.scientists.views (DjangoProjects/scinet/scientists/
views.py) ---

There is nothing special to note here other than that I am simply
getting a scientist.  The following line grabs a scientist and all
related conferences.  s = get_object_or_404(Scientist,
pk=scientist_id).  In the template file which I will show next, you
will see how I access the conferences that are associated with this
particular scientist.  Do note once again that there is no need to
explicitly import the Conference model.  Django (or Python) does this
magically (which I am curious about if anyone is up for explaining
that to me).

from django.shortcuts import render_to_response, get_object_or_404
from django.template import Context, loader
from scinet.scientists.models import Scientist
from django.http import HttpResponse, HttpResponseRedirect

def portal(request):
scientist_id = 1
s = get_object_or_404(Scientist, pk=scientist_id)
return render_to_response('scientists/portal.html',
{'scientist':s})

--- scinet.templates.scientists.portal (DjangoProjects/scinet/
templates/scientists/portal.html) ---

The key here is to understand how to traverse related models in
reverse.  Check out the link that Doug posted above.  In short,
because I chose to indicate a relationship between Conferences and
Scientists in the Conference model, Scientist must access conferences
in reverse.  I used Django's default naming of a reverse model
reference in my loop below.  In case you don't know, here is the loop
for traversing scientists that belong to a conference.

{% for scientist in 
conference.scientists.all %}
{{ 
scientist.user.get_full_name }}
{% endfor %}

In order to traverse the conferences that a scientist will attend you
must use scientists.conference_set.all.  The key differnece being
"_set".  Anyways, the template code that I used is below.

{{ scientist.user.get_full_name }}

Thank you for your answer.
I think it will be a problem, beacuse I am already using postgresql

But, how I tried to resolve my problem:

By googling found and added this one:
import os
os.environ["NLS_LANG"] = "Russian_Russia.UTF8"

So, there is no message about unicode decode problems, but I get
oracle error "ORA-12638".
Again, by googling I found how to resolve this:
comment out string SQLNET.AUTHENTICATION_SERVICES in file sqlnet.ora.

Now it is working, but I think it is bad way.
So, will try to learn this

Re: django.contrib.auth user password decryption

2009-04-05 Thread Adam N

A good solution is to reset the password through the screen.

1. Validate the user through some sort of test (secret question or
something).
2. Then send them to a screen where they can reset the password
themselves to whatever they want.
3. Initiate an email to the stored email address notifying of the
password reset (in case an imposter made the change).

It's a little less secure (because of social engineering attacks), but
it's fine for a low security site while still maintaining fundamental
security at the password data level.

Keep in mind the requirement to reset an unknown password really is
for your own good.  Two way encryption of passwords is unsafe both
because somebody can get and use them without the owner even knowing
that they've been compromised and because anybody with the decryption
key (often anybody with access to the codebase) can get passwords.

Instead of importing cx_oracle directly you should do `from django.db import
connection` which gets you a normal PEP-249 database cursor, but Django
wraps a few of the methods to make it play nice with Unicode and such.

cx_Oracle django and "dumb" connect

2009-04-05 Thread Mike RA9FTM


Hi. I need direct connection to oracle for import some information
sometimes.
Here is what I do for first test:


def orcl_test(request):
connstr='scott/ti...@orcl'
conn = cx_Oracle.connect(connstr)
curs = conn.cursor()
curs.execute('select * from dept')
rows = [row[2] for row in curs.fetchall()]
conn.close()
return render_to_response('DekanatImport/test.html', {'rows':
rows})


This django view work, when I first load it in browser. But after
pressing F5 I have following error.
By debugging it using PyDev, I found, that it appears after conn =
cx_Oracle.connect(connstr) string.

Getting errors like that means you have Django installed to the
site-packages dir of that python version, to figure out which python version
to run all you should need to do is go to each python interpretter and do
import django, and whichever one doesn't give an error is the right one to
use.

Hi,

has python2.5 installed together with the older version).
I want to run dumpdata from my application and I have the following

If I call: "python manage.py dumpdata" the second server won't work.
If I call: "python2.5 manage.py dumpdata" the first server won't
work.
I mean, I will get the following error:

Traceback (most recent call last):

How can I find the right python version to call? Maybe I can take it
from PYTHONPATH? If yes, where can I find it?

Best way to add a custom Admin form inline

2009-04-05 Thread Oni


Hi all. After a lot of pondering and reading around, I am somewhat
stuck with this problem. I have a model that requires the creation of
both an image and an initial thumbnail. The thumbnail needs user
intervention as some images will require different approaches to get
the best result.

My aim was to create a default thumbnail and allow the user to edit it
later. I have found some AJAX code written for Django that allows the
user to drag around a box shape over the top of an image and create
the required co-ordinates for thumbnails.

Now, I have manged to create a custom admin view, complete with a
customform and widget to do this. However, getting this back into the
model proved tricky.

It seems that one can have the parent class in the admin site, and
have a set of subclasses as inlines. Added an inline to the default
admin seems a create idea. However, the default settings for the
inline dont include my fancy ajax. I need to get this included.

Istarted looking at the form and formset variables within the admin
form documentation. However, I came across this bug:
http://code.djangoproject.com/ticket/8071

This seems to limit inline overriding. Is there any other way to
attempt this? Does anyone have any suggestions?

Cheers :)

Yes, you can absolutely create a views.py that isn't in a application, views
are just python functions, so they can live wherever they want, likewise so
long as your index.html is in your TEMPLATE_DIRS folder then it can be used
from wherever you like.

Re: Easy way to create pretty pages with nav?


Im just as new and i ran into exactly the same problem.

As it seems, some people suggest to create new app for just font page
(or generic public view) and create index.html as this apps front page
template.

I think it is possible to create views.py and index.html for the
project too.

Im sure someone will clear all this for us soon enough :).

For now i went for creating app for site. This app will hold stuff
like website title, meta words, language parameters and website
encoding - you'll declare them in your index html anyway, so why not
store them in your database, so you can change them from admin,
whenever  you want.

Not sure I fully understand your use case, but it sounds like this change
may have introduced an unanticipated backwards incompatibility, and one that
could lead to unexpected data deletion, which seems bad.  I suggest you
re-post this on django-developers to make all the right people see it.  It's
appropriate for there since you're discussing the effects of some recent dev
changes.  Also you might want to take a look at ticket #10711 [1] and see if
what's being proposed there would be of any use to you.

Do you need to have two, parallel, many to many relationships between Scientist
and Conference?. If the answer is no then yo don't need to define that
relationship in both models. This alone almost solves your circular reference
problem.

The technique of using a string with the name of the model instead of tthe Model
class onject iself to indicate the target of a relationship is only needed (and
accepted) when:

* The target model hasn't yet been defined (It comes after in the same
  application models.py file).

* or when you have two mutually referencing relationships between
  two models located in diferent applications (actually, this second use case
  isn't clearly explained in our documentation)

Using these guidelines and simplifying you example to the relevant bits,
something like this could be a start of a solution to your problem:

-- scinet.scientists.models ---
from django.db import models

class Scientist(models.Model):
# ...
# no many to many field needed here

-- scinet.conferences.models ---
from django.db import models
from scinet.scientists.models import Scientist

class ConferenceAttendee(models.Model):
# ...
conference = models.ForeignKey('Conference')
scientist = models.ForeignKey(Scientist)

class Conference(models.Model):
# ...
scientists = models.ManyToManyField(Scientist, through=ConferenceAttendee)


Relevant documentation links worth reading:

http://docs.djangoproject.com/en/dev/topics/db/models/#many-to-many-relationships
http://docs.djangoproject.com/en/dev/topics/db/models/#models-across-files

Easy way to create pretty pages with nav?

2009-04-05 Thread dartdog1


Ok I'm super new, skimmed the doc & tutorial but I just can't figure
out how to go about really building the Public view side? I don't see
how to apply simple css. how to set up simple stuff like navigation
tabs and links...

I'm implementing on GAE with the AEP and have gotten the sample app up
and going, have more docs to read there. But it seems to me that I'm
missing something basic, and when I search for stuff like css and page
layout I don't get much help..

For instance the sample AEP poll app has no style, I was trying to
figure out how to apply some,, but at a larger level how to do that
for a site, with navigation, and being able to take advantage of the
ability to add new apps later?

I notice that I see a number of people raving about how much they love
Django on their WP or Blogger blogs,, Which tells me that even
designing a simple Bog is not that easy in Django. Yes I have seen a
few Django blogs, but not much discussion of how they did it, and how
they apply design. For some they seem to use a mix of other tools and
some undisclosed black magic?

AEP has two sample blogs but truthfully they look pretty primitive.

What am I missing?

How to get session data from template

2009-04-05 Thread Joshua Partogi


Dear all,

I'd like to get session object because I would like to figure out
whether a user is still logged in or not. I tried searching the
documents but could not find a way to do it.
Using {% if user.is_authenticated %}, the user object is only
available in one request but will be dissapeared in the next request.

Does anyone has any suggestion on how to get the auth info from the template?

Thank you in advance.

Using form validation to prevent deletion no longer works (after rev 10206/ticket #9587)

2009-04-05 Thread Dan Tallis


In my application I have a formset with can_delete.  Some custom
validation is performed on submit, to determine whether the forms
selected by the user for deletion can be deleted -- i.e. I have a
custom clean() method on the form to decide whether deletion is
permitted (based on various bits of dynamic state), which may raise a
ValidationError to prevent it.

Up to rev 10206 (which relates to ticket #9587), this worked nicely,
giving me exactly the user interface I want.  But rev 10206 has
changed things: the formset is_valid now returns True for deleted
forms even if they have validation errors, on the grounds that (to
quote) "formset with can_delete shouldn't require deleted forms to
validate".

This means that the formset is treated as valid by my view code, so it
goes ahead and tries to save the formset, whereas what I want (and
what happened prior to rev 10206) was that the form was re-displayed
to the user with a nice error message.

I understand the thinking behind #9587, but I wonder whether this
consequence -- that it's no longer (straightforwardly) possible to use
the validation mechanism to prevent deletion -- was intended.  (There
isn't much discussion in #9587 for me to tell.)

If it was intended, any suggestions on how I can best alter my
application to achieve what I want?

Regards

Dan

Django's auth is pretty good, however, I need some row-level

Novice. - _unicode_(self) not working. :(

2009-04-05 Thread Nandha


Hi,

I just started trying out Django. I am new to python too.!!

I started with poll app in the tutorial.

Adding _unicode_(self):  does not seem to change anything. I saw that
it could be because i am using older version so i followed the
installation guide and installed the development version.

Did not help!!

This is the models.py
class Poll(models.Model):
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date_published')
def  _unicode_(self):
return self.question
def was_published_today(self):
return self.pub_date.date() == datetime.date.today()


The Poll.objects.all()
gives

>>> Poll.objects.all()
[]

What am i missing??

I cannot recreate what you are describing.  My own DB is similar to what you
describe -- model instances are added not via admin but but by other code
that uses the ORM directly.  I just tried, and when I went to the change
page for one of these model instances in admin and selected "Change History"
I first got a note that the object did not have a change history, which
makes sense because it had never been changed in admin.  I then went back,
made no change to the model fields, and selected "Save and continue
editing".  When I now check the change history it has one item, with an
"Action" of "No fields changed."

So in general the admin behaves as you are asking it to.  Since you've
gotten as far as finding the code where this is done, it might be simplest
to start printing some initial/submitted values for what it is listing as
changed, then perhaps you can spot what the differences it is seeing are.

Thanks to both of you. Yeah i noticed the part about alter table and

update the model. Just python manage.py sql appname did not work - it
showed the new additions i did to model, but they did not end up in
database after syncdb.

Actually, that doc is now contradicted by the new mod_wsgi
documentation, which says WSGI is the recommended setup:
http://docs.djangoproject.com/en/dev/howto/deployment/modwsgi/

Personally, I'd go with WSGI every time - easier to set up and
configure, less memory-hungry, and more well-supported.

But that same FAQ gives you the alternative solution - run ALTER TABLE
statements on your database manually. Or you can investigate one of
the existing projects that help with this - django-evolution, south,
or dmigrations.

Why is mod_python the preferred setup for Django?

2009-04-05 Thread Continuation


According to this 
http://docs.djangoproject.com/en/1.0/howto/deployment/modpython/
"Apache with mod_python currently is the preferred setup for using
Django on a production server."

What is the advantage of mod_python over mod_wsgi and mod_fcgi?

Wouldn't WSGI, as something designed specifically for python, be a
better choice?
Also, wouldn't FCGI consume less memory than mod_python, which embeds
Python within Apache?

I'm looking for a way to deploy django that is the least resource
intensive. My original plan was to use Nginx + FCGI. Now after reading
the doc I'm not so sure.

How does Nginx + FCGI compare to Apache + mod_python?

Would love to hear your thoughts and experiences.

Yes ,i cann't see the debug on screen, but in the console
> As you've got DEBUG off, you won't see the traceback on screen. You

the expected error should be page-not-found error/404,not 500 error,
a 500 eroor will trig django send a mail to the admin,

There's no way to do this, because the model hasn't been saved yet, so
it doesn't have an ID. You will have to think of a different naming
scheme for your images, that doesn't depend on the autogenerated ID.

here, i have a function that used as a upload_to parameter in my
model. But i records my pic as screenshot_None.gif. Becouse id is
appearing when it is recorded. How can i record my images as
screenshot_id.gif ?? thanks for your response

from os.path import join, exists
from os import remove

def screenshot_path(instance = None, filename = None):
filepath = join("products",  "images", instance.product.type,
instance.product.slug, "screenshot_" + str(instance.id) + ".gif")
if exists(join(MEDIA_ROOT,filepath)):
remove(join(MEDIA_ROOT, filepath))
return filepath
