Importing a module into a custom command

Suppose I have the following Django project:

/ # Project dir
/myapp # App dir
/myapp/views.py # views file
/myapp/mymodule.py # a Python module
/myapp/management/commands/mycommand.py # command file

In the views file, I can import mymodule.py by simply writing import mymodule in views.py. However, if I do the same in mycommand.py, I get the error: ImportError: no module named mymodule. I know that to import a model, I can write from myapp.models import mymodel, but mymodule is not a model, it is a separate Python module. So, how do I import this moduel into my command file?

The fact that you are unable to do this means your myapp folder is not in the python's sys.path. The reason it worked in views.py is because mymodule.py is in the current directory of views.py Assuming your Project dir (/) is in the python's sys.path:

  1. Add a file __init__.py in myapp directory. This file can be blank.
  2. Then you can do import myapp.mymodule or from myapp import mymodule

The same logic applies for n levels deep. If you have myapp/myappdir1/myappdir2/myfile.py you can do import myapp.myappdir1.myappdir2.myfile assuming each of these have __init__.py file in them.

Check https://docs.python.org/2/tutorial/modules.html#the-module-search-path for python's module search path

Thats because of where mymodule is in relation to all of your other files.

If you type

from myapp import mymodule

In mycommand.py as long as you have set up your __init__.py files correctly in myapp and are using a setup.py file you should be fine. The modules documentation has more information on this
