How to define each model in its own file

[h@ck5t0ck]

Hi Guys,
Am very new to django and am working on a relatively large web
application which includes over 15 models.
Now I want to define each model in its own file and store them in a
folder called models, so I first created the folder "models" and
created a file "__init__.py" in that folder and defined each model in
a separate file but its not working.
Any help on this?

Cal - 

I just used Django to write a credit card processing application (as in 
internet gateway w/API for third party sites).  Zope would have simply been 
way to heavy to handle the transaction load, and frankly, most financial 
applications fit the RDBMS model much better than the object database model.  

On the SME/Enterprise statement: Just because a software package is not 
complicated does not mean that it does not fit in the enterprise space.  I've 
found that often the more simple a tool is the *better it fits* in large 
organizations.

Upgrading to 1.2.4

[vanderkerkoff]

Hi Guys

I've gone a long way to upgrade an application we wrote in ages ago in
really old django to new django, I've got stuck some way into it
though.  Front end all sorted, I can fire up the app so the admin.py
stuff is all working, but when I click on anything inside the admin,
for this example we'll use Groups, I get an error.

Caught ImportError while rendering: No module named urls

referring to

In template /Library/Python/2.6/site-packages/django/contrib/admin/
templates/admin/change_list.html, error at line 11

The line is

{% url admin:jsi18n as jsi18nurl %}


I'm using django1.2.4

I've got all this in my urlsCONF

from django.conf.urls.defaults import *
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
(r'^admin/(.*)', admin.site.root),

If I try clicking on any of the other applications in this project
they all give the same error.  It's like I'm not passing the url stuff
over to the templates, but only the admin templates.

I'm obviously doing something stupid, any help, greatly appreciated.

Re: How to know if is a update or insert??

[andmart]

In a insert or in a update, the pk is already filled in
ModelAdmin.save_model.

The creation of object in database is in ModelForm.save.

So, I think it's not the way to handle it.

I notivced googling there is a boolean parameter named change and I'm
using it.

Doesn't seem so terrible to me, but if you're likely to do it in
several places you could use a custom ModelManager [1] with a
create_game_and_teams() function to set everything up correctly.

[1] http://docs.djangoproject.com/en/1.2/topics/db/managers/

BTW, when using super, it isn't necessary to pass 'self' explicitly;
it will be prepended to the argument list automatically as with any
other method call [2].

Re: How to define each model in its own file

[Mark (Nosrednakram)]

If there isn't anything in your models/__init__.py nothing will get
loaded.  You might try somthing like the following in your models/
__init__.py:

from app.models import modelname
from app.models import anothermodelname

Where modlenames are actually individual files with model definitions.

Sorry not in a position to test but believe this should work.

Re: different length queries

[gintare]

Thanks a lot for the answers!
I did not found that it is possible to use dictionaries and lists in

In the end i used raw function to form string according form input.
Lists and Dictionaries is much better way, since i am not tied to
certain database.

File Upload

[vanderkerkoff]

Hello everyone

I'm trying to upload a file in a project, the app is called Documents,
here's the admin.py

from django.contrib import admin
from governors.documents.models import Document
import datetime

class DocumentAdmin(admin.ModelAdmin):
fields = ('title','slug','the_file','lang_code')
list_display = ('title',)
search_fields = ('title',)
prepopulated_fields = { 'slug': ('title',) }
ordering = ('title',)

admin.site.register(Document, DocumentAdmin)

I keep getting an error I don't understand

Exception Type: AttributeError at /admin/documents/document/add/
Exception Value: 'tuple' object has no attribute 'startswith'

Here's the stack trace

http://dpaste.com/391662/

Anyone got any ideas?

Again, it's more than likely my idiocy shining through again :-)

CheckboxSelectMultiple widget not ticked correctly according to loaded CharField value

[Haisheng HU]

So I have a form:
class ProjectUpdateForm(ModelForm):
products = MultipleChoiceField(label = u'Products', 
widget=CheckboxSelectMultiple)
def __init__(self, *args, **kwargs):
self.fields['products'].choices = [(x.code, x.name) for x in 
Product.objects.order_by('code')]


which was referenced from a view:
class ProjectUpdateView(UpdateView):
model = Project
form_class = ProjectUpdateForm


The products field can be created from a similar form successfully and saved 
to database CharField as a list of values. Eg. [u'A01', u'A02']. But for 
this update view, the corresponding checkboxs always keep unchecked, 
neglecting the field value of the model object.

What did I miss? Thanks in ad!

More interesting than the admin.py for this model would have been the model
definition itself.

Stack trace seems to be indicating a problem with your file field's
upload_to value. Doc for that value is here:
http://docs.djangoproject.com/en/1.2/ref/models/fields/#filefield. Traceback
seems to be saying you've got it defined as a tuple rather than a string or
callable.

Re: File Upload

[Chris Hannam]

Hi,
startswith is usually a string method. Looks like something is calling
.startwith() on a tuple rather than the expected string.

When you instantiate your model are you certain all the values are correct?
Try logging all the values before creating the model and look for a tuple
where there should be a string.

Re: handle runtime exceptions in django view functions

[Shawn Milochik]

Use Python's logging.

http://docs.python.org/library/logging

If you're using the 1.3 beta, logging config is built into settings.py.

Then, in your try/except blocks, you can log anything you want; pass the 
exception message and the traceback into your call to the logger, and 
it'll all be there when you want it.


You'll probably want to add multiple logging handlers. We use a file 
handler and an e-mail handler. Anything log.error and above is e-mailed 
in addition to being written to log files. Everything else is just 
written to log files.

Give your model metadata by using an inner class Meta, like so:

class Ox(models.Model):
horn_length = models.IntegerField()

class Meta:
ordering = ["horn_length"]
verbose_name_plural = "oxen"

I cut and pasted that model definition, plus the model admin shown earlier,
into a test project, and I'm able to add Documents in the admin with no
error. It seems that somehow you are running code other than what you have

Database per user

[Giilp]

Hi,

I am a starting in Django, working on the architecture of my future
application.
My application involves users creating a large amount of points. In
the old application (php), there was significant perf. issues because
of the large amout of points in the database.
I was wondering if it would be possible to have a database/user
(sqlite) using Django.

Thanks.
Gillesp

Re: File Upload

[vanderkerkoff]

Hi Karen

I promise you I'm changing the code that I'm displaying, I've been
updating the app all day,  just tying off some loose ends now.

I've tried copying and pasting all the variables but it looks like
garbage in dpaste.

One thing that I'm not sure if right is the value of the the_file
variable in the output

VariableValue
the_file


Not sure if that is correct

I seem to remember hearing about a situation where you had to save the
file to the filesystem and the record of the file to the  database in
a certain order

hmm

will keep digging

this is a brand new mac install if that's anything to go by

thanks for helping, it is really appreciated

Re: File Upload

[vanderkerkoff]

I got it :-)

import os
PROJECT_PATH = os.path.abspath(os.path.dirname(__file__))

# MEDIA_ROOT = (
#   os.path.join(PROJECT_PATH, 'static/media/'),
# )

MEDIA_ROOT = '/Users/mjdavies/Sites/django/governors/static/media/'

statically pointing the media root works


I use the same method above to grab templates, and that works ok

at least we got it sorted

thanks again

You rather threw out the baby with the bathwater there. The problem with
your original setting was that you made MEDIA_ROOT a tuple, not a string.
Just fixing it to be the right type, but still dynamically computed based on
your project's location, would have been sufficient.

Note TEMPLATE_DIRS is supposed to be a tuple:
http://docs.djangoproject.com/en/1.2/ref/settings/#template-dirs

while MEDIA_ROOT is supposed to be a string:
http://docs.djangoproject.com/en/1.2/ref/settings/#media-root

You need to adjust your method when cribbing from one setting to another and
ensure you give each setting a value of the appropriate type.

Note also this is why I suggested taking a look at (not necessarily posting
to the list) the values of the local variables on the debug page. The code
you were focused on (model and model admin defs) was correct, and the
problem was elsewhere. Seeing the actual value of s that was being used
(presumably the tuple MEDIA_ROOT had been set to) might have given you a
clue as to where the problem was.

If you have difficulty understanding all that is presented by the debug page
and how to make use of it, there is a book linked from the page in my sig
that may be helpful to you in improving your debugging skills.

Hi,

http://docs.djangoproject.com/en/1.2/topics/db/multi-db/ contain

idea how this would scale to may users.
If you are looking to store large amounts of data I would look at an
alternative to SQLite. I have found http://www.postgresql.org/ to work
very well with large datasets.

Re: Use development server database with production server

[Cal Leeming [Simplicity Media Ltd]]

Hi,

Here is the the way that we have done it for the last 18 months, and has
proven very useful and almost human error free.

I've posted all the concept inside:
http://djangosnippets.org/snippets/2349/

This method allows you to separate the settings.py based on the local server
hostname, and/or the environment variable specified.

For example:

DJANGO_ENVIRONMENT=dev /path/to/manage.py shellDJANGO_ENVIRONMENT=prod
/path/to/manage.py runfcgi

Re: Amazing work

[Cal Leeming [Simplicity Media Ltd]]

Interesting. See, when I compared Zope to Django, I found Django's extensive
documentation and feature set to be perfect for prototyping, and then
optimizing bottlenecks at a later date, either via C extensions, raw SQL
replacement etc. However, as 'cliché' as this may sound, most large
enterprises tend to steer towards the most complicated, most bloated, most
difficult to use "technologies" there are around. Take Microsoft CRM, Java
and *anything* RHEL based as a clear example (others may disagree, this is
just my opinion as I'm a hard headed debian/python guy ;p)

How can I show a list of values in a text input field?

[Nate Reed]

I posted this question on StackOverflow, too.  I have defined a Model
with a ManyToManyField, and I want the field to show the values joined
by spaces, for example:



I have defined the form to use CharField to represent the multiple values:

class MyForm(ModelForm):
foo = CharField(label='Foo')
class Meta:
model = MyModel

Instead of showing the values separated by spaces, the input field
shows this instead:

[u'val1', u'val2', u'val3']

How can I override this behavior?  My understanding is that widgets
are responsible for rendering the input.  Is there an example of a
custom widget that does something like this?

5 GET request after one AJAX request

Hi,

title may be confusing, I explain myself.
Using Django, I recently put in place AJAX request handling in my
views.

Before, no problem :
- one adress typing on client side <-> one GET request on server side
- one click on Submit button on a form (client-side) <-> one POST
request on server side


After :
- one adress typing on client side <-> one GET request on server side
- one click on Submit button on a form (client-side) <-> one POST
request on server side
but
- one input modification (which calls $.getJSON, what I call AJAX
REQUEST) <-> one AJAX handling by my view (GET request on specific
url) and then 5 GET request on server side ...


Here is the code preparing my AJAX request on client side :
[...]
$.getJSON('',dict)
[...]

with dict something like :
dict['foo'] = 0

which results in calling : url?foo=0

And here is how I handle this on server side :
[...]
if request.GET.keys():
return
HttpResponse(simplejson.dumps(AJAX_answer),mimetype='application/
javascript')
[...]

with AJAX_answer another dict to be read by javascript on client side.

Any clue concerning the origin of those 5 GET requests ?

Thanks !

Large organizations can screw anything up. With Django, they can screw it up 
while hitting all the deadlines.
