Hi Florian,
I have been working on the problem the whole weekend and after trying
all the mog_wsgi debugging method I still do not have a solution. I do
know that the error does not lie in my django code or my apache
configuration as I did the exact setup on a ubuntu machine and it
works 100%. It

Hi Martin,
Thanks for the tip. The thing is that I store my class names in the
database. So

form_class = models.CharField(...)

I should add that in the B class function get_a_class I only have a

Hi,
I am constantly running in a brick wall when it comes to deleting
records in Django. If you have one or two foreign keys it is easy to
check if they are in use, but once an application starts getting big
you can not remember which models are making use of a foreign key and
if a specific foreig
Typically I simply want to do a left join but have it as an object in
django rather than a sql raw query.
The queryset would look like.

b.code as 'customer_description',

Hi,
I have a tricky one, I don't have an error but rather trying to avoid
many database hits.
I am trying to build a product database which can have different field
values per customer.
So the model would look something like this.
class Customer(models.Model):
name = models.CharField(max_le
Ok, I think I have sorted out my queryset problem, I wrote a custom
manager:
class UserBranchModelManager(models.Manager):
def for_request(self, request):
if settings.DO_BRANCH_FILTER:
return super(UserBranchModelManager,
self).get_query_set().filter(branch__pk = request.us
Just as a suggestion, if you don't need to customize the get_user()
method then simply don't have a get_user() method in your custom
authentication class.

Sorry one more thing, the above filters my querysets but then comes

Hi Shawn,
I use Managers often to limit my querysets and add additional fields
that I want dynamically calculated using sql. I just don't see how I

I know I could do a filter in each view

Hi,
I am not sure if this is a really stupid question but how can you
filter a model by comparing two of it's own fields?
for example:
class X(models.Model):
id = models.IntegerField()
new_id = models.IntegerField()
now I want to say X.objects.filter(id = new_id)

Thank you for your help. I guess I will have to create temp table etc
and do it that way. It's a pity django does not provide this kind of

Thanks for you reply Mikhail,
I do use model managers but more often to get a certain defined

implement your suggestion?
I imagine it looking something like this.

Sorry I would also like to add that I would like to sort by this field
in generic views. So results = Person.objects.filter
(compare_to_others__gte = 1).order_by('compare_to_others')

Hi all,
I keep running into a problem. Often when creating models for existing
databases which you can not modify, I find myself in need of quite a
few model methods. That all works fine but then when I run a view I
would like to be able to use the object mapper to filter by the method

Hi,
I am not sure if truncating the data is a good solution as the user
will be under the impression that all the text was saved whereas only
the first 255 was really saved.
You can add a max_length to your form or modelform field which will
block the user from typing more then the max length.
Hi,
Could you provide the code of your model and why you would want to use
a custom sql instead of the django model object.
Regards
Pbzrpa
