Django not enforcing blank=False on a model

[Knight Samar]

Hi,

I have a model

> from django.db import models
>
> class Organization(models.Model):
> name = models.CharField(max_length=100,
> blank = False,  #mandatory
> help_text = "Name of your Organization",
> verbose_name = '',
> unique = True,
> primary_key = True,
> )
>
>
and a piece of code

> from organization.models import Organization
> o = Organization.objects.create() 
> o.save() 


which works *without raising an IntegrityError!* And the following also 
works just the same!

> from organization.models import Organization
> o = Organization() 

o.save() 


I am using SQLite3(SQLite 3.7.9 2011-11-01 00:52:41 
c7c6050ef060877ebe77b41d959e9df13f8c9b5e) as the database backend and it 
shows the following as the schema:

CREATE TABLE "organization_organization" ( "name" varchar(100) NOT NULL 
> PRIMARY KEY ); 

 
Even if SQLite3 was buggy, shouldn't Django itself enforce the constraint 
on ORM layer ?

I have deleted .pyc files and also the .sqlite3 file before testing again. 
I am using Django 1.5.1

What am I missing ? Why is Django *NOT* enforcing blank=False ?

Re: invalid literal for int() with base 10

[Nathan Knight]

Just so you know, it is bad practice to use "import * " when importing 
modules in python.
With many modules being used, you can run into conflicting definitions. 
Plus, it increases overhead - potentially an exponential decrease in 
performance!

Re: Management form in Model Formsets

[Knight Samar]

Thanks Thomas! I checked the script and tried to follow it.

It seems that for Django 1.2, *not* modifying the form-TOTAL_FORMS, 
form-INITIAL_FORMS and form-MAX_NUM_FORMS works properly!!

Management form in Model Formsets

[Knight Samar]

Hi,

I am using Django 1.2 and developing using Model formsets. Using 
JavaScript, I am allowing the user to dynamically "Add another" formset on 
the template, but I can't figure out what exactly I have to modify in the 
management forms, for all the formsets to be successfully saved.

The documentation points out to three properties in the management form - 
form-TOTAL_FORMS, form-INITIAL_FORMS and form-MAX_NUM_FORMS. But I don't 
understand, which properties I have to exactly modify and how, when a new 
formset is being added dynamically using JavaScript ?

Thanks :)

Regards,
Samar

Getting children of an ABC

[Knight Samar]

I am using Django 1.3.1 and I have the following piece of models:

class masterData(models.Model):
uid = models.CharField(max_length=20,primary_key=True)

class Meta:
abstract = True;

class Type1(masterData):
 pass;

class Type2(masterData):
 pass;

Now, I am trying to get a list of all child classes of masterData. I
have tried:

masterData.__subclasses__()

The very interesting thing that I found about the above is that it
works flawlessly in *python manage.py shell* and does NOT work at all
when running the webserver!

So how do I get the models derived from an Abstract Base Class model ?

Samar

Documentation error?

[Adam Knight]

On the description for django.contrib.auth.views.login at
http://docs.djangoproject.com/en/1.2/topics/auth/#django.contrib.auth.views.loginthe
documentation says:

If you are using alternate authentication (see Other authentication sources)
> you can pass a custom authentication form to the login view via the
> authentication_form parameter. This form must accept a request keyword
> argument in its __init__ method, and provide a get_user method which returns
> the authenticated user object (this method is only ever called after
> successful form validation).


Note the phrase "This form must accept a request keyword argument in its
__init__ method".  When I do this as it literally states and expect a
"request" keyword argument, I don't get a request.  When I looked at
django.contrib.auth.views.login on line 31 I see that it's actually setting
the keyword argument "data" instead.

Did I miss something or is this a bug I should file?

(Yes, expecting the "data" keyword works perfectly, but it's not in the
documentation that I can see.)

moving to django 1.2.1

[knight]

Hi,

I have pretty big django app running on django 1.0.2 and I want to
move it to django 1.2.1 since I want to use multiple databases.
What are the minimal changes that I need to make in order to work with
1.2.1?
I mean, what should I do regarding csrf and so on...
Is there a good place to read other than django documentation?

Thanks, Arshavski Alexander.

uploading file in 2 steps

[knight]

Hi,

I want to upload a file in 2 steps.
First I want to upload it and show the errors and on the second step I
want actually to save the file data in the database.
So I made a simple form and my problem is how to pass the same file to
the form on the second step.
I mean how to insert request.FILES data in the same form again. Or
maybe there is a better way?

forms question in django 1.1

[knight]

I have the following form:

class ModuleItemForm2(forms.ModelForm):
class Meta:
model = Module_item
fields = ('title', 'media', 'thumb', 'desc', 'default',
'player_option')

The model is:

class Module_item(models.Model):
title = models.CharField(max_length=100)
layout = models.CharField(max_length=5, choices=LAYOUTS_CHOICE)
media = models.CharField(help_text='Media url', max_length=500,
blank=True, null=True)
conserv = models.ForeignKey(Conserv, help_text= 'Redirect to
Conserv', blank=True, null=True)
conserve_section = models.CharField(max_length=100, help_text=
'Section within the redirected Conserv', blank=True, null=True)
parent = models.ForeignKey('self', help_text='Upper menu.',
blank=True, null=True)
module = models.ForeignKey(Module, blank=True, null=True)
thumb = models.FileField(upload_to='sms/module_items/thumbs',
blank=True, null=True)
desc = models.CharField(max_length=500, blank=True, null=True)
auto_play = models.IntegerField(help_text='Auto start play
(miliseconds)', blank=True, null=True)
order = models.IntegerField(help_text='Display order', blank=True,
null=True)
depth = models.IntegerField(help_text='The layout depth',
blank=True, null=True)
flow_replace = models.IntegerField(blank=True, null=True)
default = models.IntegerField(help_text='The selected sub item
(Note: Starting from 0)', blank=True, null=True)
player_options = models.CharField(max_length=1000, null=True,
blank=True)

In my view I build form:

module_item_form2 = ModuleItemForm2()
print module_item_form2

And I get the following error on the print line:

'NoneType' object has no attribute 'label'

It works fine with django 1.0.2. I see the error only in django 1.1.

Do you have an idea what am I doing wrong?

search and filtering in app engine

[knight]

Hi,

I'm trying to add filter and search to my site.
It's exactly the same code as in another working django project. The
difference is that this time I do it with app engine.

my views: http://slexy.org/view/s21GMw2sh1
my forms: http://slexy.org/view/s21XX8bquM
my search function: http://slexy.org/view/s2NOalh2uC

I have 2 problems:

1.) I get error: "'Query' object has no attribute 'all'" on line 59 in
views.
As I understand it's something to do with the fact that GAE queryset
is different from django queryset.
How can I fix that?

2.) If I have 'search' in my request.GET I also fall on line 54 in my
views.
This is because I can't search by Q object in GAE, I guess.
How can I fix that?

Thanks, Alex A.

more than 1 foreign key

I have the following models: http://slexy.org/view/s20T8yOiKZ.
When I try to click add button for worlds in admin page it shows me
the following error:

I think it's something to do with inline.
What can it be?

moving to Django 1.1 problem

[knight]

Hi,

I'm trying to move from django 1.0.2 to 1.1 and I am getting the
following error in one of my templates:

Request Method: GET
Request URL:http://localhost:8000/conserv/media_assets/vod/
Exception Type: TemplateSyntaxError
Exception Value:Caught an exception while rendering: 'NoneType'
object has no attribute 'label'
Exception Location: /opt/local/Library/Frameworks/Python.framework/
Versions/2.6/lib/python2.6/site-packages/django/template/debug.py in
render_node, line 81
Python Executable:  /opt/local/Library/Frameworks/Python.framework/
Versions/2.6/Resources/Python.app/Contents/MacOS/Python
Python Version: 2.6.2

The error is on the line with the "for" tag.
My template:

{% for field in upload_image_form %}


{{field.name}}


{{field}}


{% endfor %}

My form:

class UploadImageForm(ModelForm):
class Meta:
model = ImageUpload
fields = ('thumb')

My model:

class ImageUpload(models.Model):
thumb = models.FileField(upload_to='thumbs', blank=True,
null=True)


Does anyone know how can I solve it?

Thanks,
Arshavski Alexander.

I mean, I can load the fixtures with loaddata and I'm importing from

django running xp problem

[knight]

I have OSX machine running django app with appengine launcher and a
wirtual machine with windows XP running the same app.
The problem is that I have 2 XP machines where I get: "No module named
urls". What can be the problem? Maybe some system variables?
The code is exactly the same.

mod_wsgi configure problem

[knight]

Hi,

I need my django app to listen to port 80 and port .

I have 2 servers. One is listening to both ports and one is not
listening to .
The first one's apache conf is:

Listen 
WSGIRestrictStdout Off
WSGIPassAuthorization On
LoadModule wsgi_module modules/mod-wsgi.so
WSGIScriptAlias /peergw /home/user/mx30/django.wsgi


Order deny,allow
allow from all


Alias /media/ "/var/www/media/"
Alias /peergw/site_media/ "/var/www/site_media/"


Order deny,allow
Allow from all


WSGIScriptAlias /peergw_test /home/user/test/mx30/django.wsgi
Alias /peergw_test/site_media/ "/var/www/site_media_test/"



The second one is (The one that doesn't listen to ):

Listen 
WSGIRestrictStdout Off
WSGIPassAuthorization On
LoadModule wsgi_module modules/mod-wsgi.so
WSGIScriptAlias /peergw /home/reeptv/mx30/django.wsgi


Order deny,allow
allow from all


Alias /media/ "/var/www/media/"
Alias /peergw/site_media/ "/var/www/site_media/"


Order deny,allow
Allow from all



The main difference are the last 2 lines. Does anybody has an idea how
can I make the last one listen to  and 80?

Regards,
Arshavski Alexander.

App engine launcher on windows problem

[knight]

I'm trying to install app engine with django 1.1 on windows.

When launching the app engine I'm getting the following error:
http://slexy.org/view/s21oLrbkHh
The steps I do are:
1.) Create new app via launcher
2.) Copy my code (Which is empty django project)

My main.py code: http://slexy.org/view/s21oxoNqVv
I'm falling on line: "import django.db" which I can do successfully
from cmd. Do you have an idea what I'm doing wrong?

http://docs.djangoproject.com/en/dev/topics/db/aggregation/#generating-aggregates-over-a-queryset

prices = StockPrice.objects.filter(stock__market=SomeMarket,  ... and so on
avg = prices.aggregate(Avg('price'))

Or something like that.  Basically, you approach it from the other end.  You 
want the market's aggregate, but the answer to that is an average of StockPrice 
objects, so you search for them with the conditions you want and then apply the 
aggregate operation to that.

Drupal migration

[Adam Knight]

Has anyone migrated a Drupal 6 site before?  I have all the nodes, comments, 
and URLs coming across but now that I start on the taxonomy bits I'm running 
into some problems with how they did their tables versus what would have been 
sane (lack of a primary key column and, instead, a joint unique column in 
termnode).

So, has anyone done a migration before (that included taxonomy) and have some 
code (preferably some models) laying around that I could poke around with?

Re: Help with manage.py syncdb

[Adam Knight]

What everyone else said.  But, also, Snow Leopard made Python complicated.  It 
ships with 2.4, 2.5, and 2.6.  There's an easy_install for each version.  If 
you easy_install the MySQLdb module without specifying which easy_install 
you're using, it will use whatever the default version of Python is (defaults 
to 2.6 unless you changed it).  The backtrace indicates you're using Py 2.6, so 
you should be okay, unless you ran easy_install-2.5 to install the MySQL 
module, in which case the wrong version of Python received the module, in which 
case 2.6 won't find it.

Yay, something to make it more complicated!  Woo!

wsgi config

[knight]

Hi. I have a problem with configuring my django site with mod_wsgi.
My httpd.conf is:


LoadModule wsgi_module modules/mod-wsgi.so
WSGIScriptAlias /peergw C:/mxhw/mx30/django.wsgi


Order deny,allow
allow from all


Alias /media/ "C:\Program Files\Apache Software Foundation
\Apache2.2\htdocs\media"
Alias /peergw/site_media/ "C:\Program Files\Apache Software Foundation
\Apache2.2\htdocs\site_media"


Order deny,allow
Allow from all



I want my site to run on /peergw since I have many instances on the
server and each one running with the different prefix.
Everything works fine except all the images - I can't see static media
files both in admin and my site.
When I go to "/site_media//image" and not "/peergw/site_media//
image", I do see the image.
What am I doing wrong?
By the way, I'm running on Vista, but I have the same problem on XP.

Thanks, Arshavski Alexander.

extends tag in template

[knight]

Hi,

I have override 2 admin templates: index.html and base_site.html.
The first line of index.html is: {% extends "admin/base_site.html" %}
Everything works fine, but if I insert {{ MEDIA_URL }} in
base_site.html, I get the following error when going to my admin page:

TemplateSyntaxError at /admin/
 must be the first tag in the
template.

Is anybody have an idea why can't I put {{ MEDIA_URL }} in
base_site.html?

Thanks, Arshavski Alexander.

Disable apache directory browsing

[knight]

Hi,

I have installed django app with wsgi. I see that by default I have
directory browsing enabled in my static files and I want to turn it
off.
My httpd.conf:

LoadModule python_module modules/mod-wsgi.so

WSGIScriptAlias /peergw /home/alex/mx30/django.wsgi

Alias /media/ /var/www/media/
Alias /peergw/site_media/ /var/www/site_media/

How can I turn off directory browsing from /peergw/site_media? (It's
my static files)
I tried "Options -Indexes", but without luck.

Thanks in advance, Alex Arshavski

apache write permissions

[knight]

Hi,

I have a django project with the following apache configuration:

LoadModule python_module modules/mod_python.so

SetHandler python-program
PythonPath "['/home/alex'] + sys.path"
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE mx30.settings
PythonOption django.root /peergw
PythonDebug Off

Alias "/peergw/site_media" "/var/www/site_media"

SetHandler None

Alias "/media" "/var/www/media"

SetHandler None

Listen 


I have added backup and restore buttons on admin page. They use
dumpdata and loaddata.
Backup data should save the backup in /home/alex/mx30/backups
directory.
I succeed to backup the data with django development server but can
not do it with apache.
Can anyone give me a suggestion how to give apache write permissions
to my /home/alex/mx30/backups directory?
Tried to give all permission to directory and change owner to www-data
and it didn't help.

Thanks, Arshavski Alexander.

encoding question

[knight]

Hi,

I have html page with inline editing. (I have text, that when I click
on it, it changes to edit box, and I can change the text)
I do it with some java scripts. (http://www.yvoschaap.com/index.php/
weblog/ajax_inline_instant_update_text_20/)
The problem is that I should save the text that I change in the
database of my django application and what I get after text change is
unicode.
I mean, something like: %u05D9%u05D2.

Maybe someone has an idea how can I save the hebrew letters, for
example, correctly in the database?

python version

[knight]

Hi,

I have 2 servers with my django app:
The first one has python2.5 as default python and the second don't (It
has python2.5 installed together with the older version).
I want to run dumpdata from my application and I have the following
problem:
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):
  File "manage.py", line 2, in 
from django.core.management import execute_manager
ImportError: No module named django.core.management

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

Could not import settings

[knight]

Hi,

I'm trying to install my django application on CentOS 5 and I'm
getting the following error:

ImportError: Could not import settings 'mx30.settings' (Is it on
sys.path? Does it have syntax errors?): No module named mx30.settings

My httpd.conf looks as follows:

Listen 80

SetHandler python-program
PythonPath "['/home/peertv', '/home/peertv/mx30', '/usr/lib/
python2.5'] + sys.path"
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE mx30.settings
PythonOption django.root /peergw
PythonDebug On
PythonInterpreter mx30


I can do python settings.py, so I don't have spelling errors.
I can import settings from shell.
I have all the permissions to mx30 directory where the settings are
located.
I tried all the things in the similar threads here.

Can you please give me the directions where else I can look for a
solution?

Thanks, Arshavski Alex.

Languages problem

[knight]

Hi,

I have the following class in my models.py:

class MainCategory(models.Model):
title = models.CharField(max_length=50)
value = models.DecimalField(default=0, max_digits=5,
decimal_places=3)
secid = models.SlugField(max_length=1000, editable=False)
def save(self):
if not self.pk:
self.secid = slugify(self.title).replace("-", "_")
if MainCategory.objects.filter(secid = self.secid):
super(MainCategory, self).save()
self.secid = "%s__%s" %(self.secid, self.pk)
return super(MainCategory, self).save()
def __unicode__(self):
return self.title

I have the following problem:
If I create new object with title on Russian or Arabic or any other
language, I see it in admin with the empty string instead of it's
title.
My database is postgres and its utf-8.
I guess it's something to do with unicode but I can't understand what
exactly.
Do you have any ideas?

Thanks, Arshavski Alexander.

default value for foreign key

[knight]

Hi,

I have models.py like this:

class Media_biz(models.Model):
---
default = models.BooleanField("Default", blank=True, null=True)
---

def get_default_Media_biz():
if Media_biz.objects.filter(default=True).count() != 0:
return Media_biz.objects.filter(default=True)[0]
else:
return None

class Metadata(models.Model):
---
media_biz = models.ForeignKey('Media_biz',
default=get_default_Media_biz)
---

What I want is to set the default value of Media_biz in Metadata. The
problem is:
When I create a new database and run syncdb, I get:
psycopg2.ProgrammingError: relation "cms_sample_media_biz" does not
exist

How can I check that the Media_biz table exist in the database?

Re: default value for foreign key and CharField

[knight]

Thanks,

My Media_biz is edited inline in another class. So I have:
class MetadataInline(admin.StackedInline) and
class MetadataAdmin(admin.ModelAdmin)

Can you tell what method I should override and in which class in order
to set the initial value while editing inline?

Regards, Alex Arshavski.

Re: default value for foreign key and CharField

[knight]

Hi,
Thanks for the fast reply.
Each Default instance provide default value for one of the fields:
I want to take the default value of rental_period to rental_period and
default value of currency to currency.
The value of the currency should be the name of Currency object for
foreign key.

Thanks, Alex A.

default value for foreign key and CharField

[knight]

Hi,

I have the following classes in my models.py:

class Default(models.Model):
name = models.CharField(max_length=50, choices =
(('rental_period', 'rental_period'), ('currency', 'currency')),
unique=True)
value = models.CharField(max_length=50)

class Media_biz(models.Model):
name = models.CharField(max_length=50)
currency = models.ForeignKey(Currency)
rental_period = models.CharField(max_length=5, blank=True,
null=True)

What I want is:
When I add new Media_biz in my admin page, I want to check if there is
a Default object with the name "currency" or "rental_period" and take
it's value as default.

I tried to use "default" field option for this, but I can't insert
logic that checks Default objects in models.py, because it fails on
syncdb if my db is empty.

Does anybody have a solution how can I do that?

Thanks,
Arshavski Alexander.

Re: Overriding admin template: index.html

[knight]

My problem is that I want to pass additional variables to index.html.
So I thought I can do it if I add these variables to view that renders
index.html.

Re: Changing default app url in development server

My production version is running on different computer with apache

I want them both to run on http:///peergw.
The port has no difference.

Changing default app url in development server

Hi,

My question is:

Is there a way to change my default app url in development server

If it's a problem, maybe someone have a good reference for configuring
apache server on MAC.

Re: Filtering parents by child attributes

[knight]

Try something like:

students = Student.objects.all()
absences = Absences.objects.all()
for absence in absences:
students.remove(absence.fk)

Maybe I'm wrong somewhere in the syntax, but the idea should be clear.

Re: Templates dir exception

I think you can try accessing books/publisher_list.html instead of

ManyToMany problem

[knight]

Hi,

I have the following problem:
I have models.py with the following class:

class Section(Feed):
parent = models.ManyToManyField('self', blank=True, null=True)
depth = models.IntegerField(editable=False)
def save(self):
self.depth = 1
if self.parent:
self.depth = self.parent.depth + 1
return super(Section, self).save()
def __unicode__(self):
return "Section_%s" %(self.title)

and admin.py with the following classes:

class SectionInline(admin.TabularInline):
model = Section
extra = 2
verbose_name_plural = "Sub Sections"

class SectionAdmin(admin.ModelAdmin):
inlines = [
SectionInline, ItemInline
]


When I try to save new Section from the admin page, I get the
following error:

'Section' instance needs to have a primary key value before a many-to-
many relationship can be used.

There are 2 things that I don't understand:

1.) Why am I getting this error, if my ManyToMany relation is optional
2.) I tried many things including defining id of the Section with
AutoField but still without luck.

Does anyone have an idea what is my problem/mistake here?

Thanks, Arshavski Alexander.

Re: Problem with loading fixture xml to Postgres database

[knight]

I'm not sure, but I think it's a problem with the psycopg backend
under Python 2.3.5.
When I loaded fixtures with Python 2.3.5 I got no errors and the
fixtures haven't been loaded.
When I loaded fixtures with Python 2.5 I got an error and when I fixed
it the fixtures were loaded.
I used the same fixtures data.
I'm sorry, but I don't have Python 2.3.5 environment anymore, so I can
not check it.

If I put the objects in my fixture in the right order, I can see them

Do you have any other suggestions?

Problem with loading fixture xml to Postgres database

[knight]

Hi,

I have a large fixture initial_data.xml and I'm trying to syncdb on
new Postgres database, & though it says it imported 764 objects, I see
none in the db.
After a little investigation, I think it is related to dependencies
between classes (foreign keys), which aren't handled in the right
order.
I'm using Python 2.3.5, Postgres 8.1.2 & Django dev version.
The fixture was generated from a database of the same type and
version

Is this a known issue? Is it related to Postgres or its DB API?
I need urgent help, and any idea/direction would be highly
appreciated!

Thanks in advance,
Alex.

Problem with loading fixture xml to Postgres database

[knight]

Hi,

I have a large fixture initial_data.xml and I'm trying to syncdb on
new Postgres database, & though it says it imported 764 objects, I see
none in the db.
After a little investigation, I think it is related to dependencies
between classes (foreign keys), which aren't handled in the right
order.
I'm using Python 2.3.5, Postgres 8.1.2 & Django dev version.
Is this a known issue? Is it related to Postgres or its DB API?

Thanks in advance,
Alex.

No, I neve touched any of those

I guess it has to do with the fact that I do not have article.id
property.

What did I do wrong in models this time around
