When writing a method for one of my model classes, I find that I want
to access a function from another module. The reference documentation
(http://www.djangoproject.com/documentation/model_api/#model-methods)
is plenty clear on the fact that you can't just import a module at the
top of the
I'm faced with the multiple-schema problem in MySQL, which AFAICT is a

you don't have to coordinate multiple connections. Actually, it
basically already works. I wrote

hi
what are the best practices for translating content in the database,
and storing that? I feel that for postgres, a separate schema for
each language may be good - that way, just something like
django-admin.py install new language would just duplicate the
necessary tables in a separate
In my experience, some designers used primary key to enforce logical
parent/child relationship (where the parent's pk is prefixed into one of
the child's primay key), and usually to signify the pk fields to be
"uneditable" since it actually also doubles as "foreignkey", the value

Django still supports Python 2.3, so scripts need to be able to run
with Python 2.3.

I am experimenting with Django and MS SQL and it appears that Django is
passing parameters to MS SQL in an incorrect format.
The params are being passed in as a format string style (%s), which MS
SQL chokes on.
Is anyone here using MS SQL that might be able to shed some light on
this problem?

I wouldn't recommend
Adrian,
Actually, this was the 'aha' answer to my question. Thank you. On a
different note, is there anyway to implement approach #2, having
NewsPosting have a user_id field in django-way? If not so, is there any
reason why not?

Having said that, I just remembered there's a common practice in
designing database that I could never done in any ORM (not only
django's), and that is to have a group of fields as primary key. Ie:
Company table
- company id (pk)
- name
Employee
- company id (pk)
-
My approach is, if you would often be needing to get list of news both
by company and user, for performance reason I would put both foreignkey
(one 2 many) to company and user in newsposting model. That way, the
resulting join query only need to join maximum of two tables and be
faster.

actually, i don´t really see a difference between model 1 and 2.
you have a company which you assign users to.
Thanks Patrick,
So, you are voting for the second model. I think Django should have
such relationship builtin where I can avoid defining user_id as a field
in my news table.
I maybe wrong but I don't think (news.get_user.username) works in
templates. I have to double check.
Regards,
Mike
within a view you could use
news_list = news.get_list(user__id__exact=request.user.id)
for the logged-in user
to get the user within the template use
news.get_user.username

Hi,
I have a model with multiple companies (Basecamp Style), where each
have multiple users and multiple company news. Which of the two way is
more appropriate:
1: Company -one-to-many> User one-to-many> NewsPosting
2: Company -one-to-many> User

we´re working on a basecamp-like project management system which we´ll

therefore, we´re having custom views (based on Add- and

Hello. Is there an elegant way of passing more than one arguments to a
custom filter? What I do now is pass a tuple from the view to the
template that contains these arguments, and in the template, pass this
tuple to the custom filter (which in the filter is seen as the "arg"
parameter).
Thanks
