I am trying to create a form for my project with Django 2.0, with Python 3.6.4 in Windows 10, but when using a reference of some models of another app it tells me that it does not exist or that it is not defined, in a similar question said that a reference to the beginning using models was necessary. (models.Employee) but if I do this it tells me the following error:

and if I remove that reference the error that it tells me is the following:

When importing a model or something else by . you mean that this file is local within the same app, I explain myself better. If a Django project is made up of 2 or more example apps: RecusosHumanos, Inventory and once inside the views.py that belongs to RecursosHumanos you want to import all the models of himself, you can declare

from .models import *

In this way you import all the models belonging to the App that are found in models.py in your own Directory. The other thing is that you need in the Human Resources views.py to use one or several models of the Inventory App, then if you should verify that in your global settings.py in INSTALLED_APPS is the App that you need to use, that is the first step example:

INSTALLED_APPS = [
    'recusroshumanos',
    'inventario',
    'django.contrib.admin'
]

Once defined you can, anywhere in the Human Resources Resources App import what you need from the Inventory App. example:

RecusosHumanos / views.py

from inventario.models import *

In this way you have access from RecusrosHumanos to all the models defined in the models.py within the App Inventory. It should also be noted that this philosophy is not only applicable in the case of models, you can use it to import what you need to reuse
