Tables with same schema

Hi, I want to create several tables with same schema. This is to partition the data into different tables. Apart from having model classes with same definition, is there another way to do it? Here is a trivial example that duplicates the class definition- class Person(models.Model): first =

After sending HttpResponse

automatically generated field in admin

Hi, I have a model in which a field should be generated automatically. So it shouldn't be shown in the admin add page. Also in the change page it should be shown but should be non-editable. As an example- class Student(models.Model): first = models.CharField(max_length=64) last = models.

Admin and ManyToManyField

Hi, I have a model that has a ManyToManyField. When I try to add/edit an object of this model in admin, it says that the ManyToManyField is required i.e. I can not leave it out. While, from the shell I can easily create an object without adding anything in the ManyToManyField. The same happens fo

How to delete a session

Hi, How can I delete the session of a request? The docs speak about using session as a dict and setting and removing specific keys on that, but I want to remove the session itself, something like del request.session Any ideas? Thanks in advance, Ram --~--~-~--~~~--

Restricting q QuerySet based on ManyToManyField

Hi, I would like to restrict a QuerySet based on its ManyToManyField. In particular, based on what the ManyToManyField contains. Consider this trivial and a bit non-sense example- class User: name = models.CharField(maxlength=24) related = models.ManyToManyField('self', symmetric=False
