Dependencies between two Django projects
PyCharm adds only source folders automatically to the python path. So I marked app1 as a source folder and everything works.
I have a question concerning dependencies between two Django projects.
I have two Django Projects, P1 and P2. I want to import a form model from P2 > apps > app1 > forms > form.py. I marked P1 as depending on P2 (using Pycharm) and tried to use from app1.forms import form.py inside my model.py file of an app in P1. PyCharm now says that app1 is an unresolved reference. Is there any step I missed? 
Thank you for your help.
