Python, Django: foreignkey apps accross ne fonctionne pas

Question

Python: Django 3.6.2: 1.11.4

Nous essayons d'utiliser foreignkey dans des applications. L'adresse est consommée par le client et l'agent. Nous utilisons également un jeu de cadres en ligne. Si je mets tout cela dans une application, cela fonctionne bien, y compris en frameset inline. Si je me divise en plusieurs applications, j'ai cette erreur. S'il vous plaît voir les images ci-dessous.

Foreignkey error

File "C:/Users/palak/Desktop/mergemodels\apps\sharedmodels\models.py", line   15, in <module> 
class Address(models.Model): 
File "C:/Users/palak/Desktop/mergemodels\apps\sharedmodels\models.py", line 16, in Address 
    agent = models.Foreignkey('apps.agent.Agent') 
TypeError: object() takes no parameters

Set clé étrangère en tant que chaîne foreignkey

agent = models.Foreignkey('agent.Agent') 
#       ^^^^^^^
