How to import a module from a different folder?

Firstly, this import statement:

from models import some_model

should be namespaced:

# in myproject/backend/backend.py or myproject/api/api.pyfrom myproject.models import some_model

Then you will need to get the directory which contains myproject, let's call this /path/to/parent, into the sys.path list. You can do this temporarily by setting an environment variable:

export PYTHONPATH=/path/to/parent

Or, preferably, you can do it by writing a setup.py file and installing your package. Follow the PyPA packaging guide. After you have written your setup.py file, from within the same directory, execute this to setup the correct entries in sys.path:

pip install --editable .

Unfortunately, Python will only find your file if your file is in the systems path. But fear not! There is a way around this!

Using python's sys module, we can add a directory to the path just while Python is running, and once Python stops running, it will remove it from the path.

You can do this by:

import syssys.path.insert(0, '/path/to/application/app/folder')import [file]

It is important to import sys and set the directory path before you import the file however.

Good luck!
