Hmm. Are you perhaps trying to execute this whilst myapp.forms is still
being imported? For example, something that myapp.forms imports if
running this line of code? That won't work (until a module is fully
imported, its name exists in sys.modules to prevent circular imports,
but the value (module) attached to that name is empty, so you cannot
access the internals of a module until it's been fully imported).
If that's not the case, can you import 'myapp.forms' using the above
technique (you're probably right that a list is needed at the end, btw;
I posted without actually checking too carefully)? What I'm trying to
work out is where in the dotted import path it all goes wrong.
My first thought was that you didn't have "myapp" on your Python path
(the parent directory of myapp has to be on the Python path), but that
would probably generate a message saying it couldn't import "myapp",
rather than something about "MyModelForm" (guessing; I didn't test it).
So, how far can you get down the import chain here?
(a) klass = __import__("myapp", {}, {}, [''])
(b) klass = __import__("myapp.forms", {}, {}, [''])
(c) klass = __import__("myapp.forms", {}, {}, ['MyModelForm'])
None of these are what you want, but it might give some idea as to where
the problem really lies.
