Problem extending a model with ManyToMany field

[jjgod]

Currently, syncdb command will only create ManyToMany tables for a field if the model that field belongs to are newly created. For example, if I first have:

class A(models.Model):
      foo = ...

Then I run python manage.py syncdb, it will create a table for A model.

Then I add a new field to this model, say:

class B(models.Model):
    ...

class A(models.Model):
      foo = ...
      bar = models.ManyToManyField(B)

Then I run python manage.py syncdb again, it won't create the needed ManyToMany table for me, the only way to have this table created is to drop the previously created table for A first, then let syncdb to create them for me again. I think it is inconvenient and need to be fixed.

There's another ticket for schema migration somewhere, but long story short, this has been discussed 101 times, schema evolution will come to Djanog eventually, for now use an external project.
