Comment:
I t is not completely clear to me what is the behavior you expect here.
If what you are suggesting is that Django flags the divergence between the
model design and its corresponding database table structure as soon as
possible (e.g. at Python model field population time) it would be a waste
of resources (it would need to introspect the DB table every time). IMHO
current behavior is a good compromise: Let the DB-API driver/database
engine to flag the error when actual interaction with the DB is performed.
Remember, we are using a RDBMS plus an ORM, not a OODB, there are two
separate realms, the model objects one and the database one.
If what you are asking for is database schema evolution so it follows the
model design, it is a feature that hopefully will be added in a future
version and there are third party tools that implement that now (but AFAIK
none of them perform ''automatic'' schema evolution so they won't be of
help in cases where the developer wants to get away with changing the
model design at will and hoping the software will take care of the
database changes).
