Question

I am developing a Python App Engine app, where I want to split the content of a source code file Models.py into separate files for each model, but I want to put it all in a folder called Models. The problem is that when I do that, my app can’t find the classes anymore. What should I do?

This question is not about MVC but another question with the same title is.

Answer 1

Put an empty __init__.py file in the Models directory.

Then, in your app; presumably one level up, you reference modules in the Models directory like this:

import Models

and do something with it like this:

Models.my_model.MyClassName

You can also use the from keyword like this:

from Models import my_model

and reference like this:

my_model.MyClassName

If you only need one method from a module, you could also do this:

from Models.my_model import my_method_name
my_method_name()
