Adding custom constraint to a GeoDjango table?

Question

I wish to add a custom constraint to a GeoDjango table.

This is the corresponding sql-statement:

ALTER TABLE my_table
   ADD CONSTRAINT enforce_valid_geom CHECK (ST_IsValid(geom));

Do I really have to inject the sql directly?

That seems like a frequently occurring constraint to me.

Answer 1

I would add the constraint in a migration. Or, in something more pretty: a custom field
