 from suap.models import Employee from hr.models import WorkJourney class WorkJourneyResource(ModelResource): class Meta: queryset = WorkJourney.objects.all() resource_name = 'work_journey' authentication = BasicAuthentication() class EmployeeResource(ModelResource): journey = fields.ForeignKey(WorkJourney, 'work_journey') class Meta: queryset = Employee.objects.all() resource_name = 'employee' authentication = BasicAuthentication() 

Answer 1

1 / When you define your attitude in ressoure.py

you need WorkJourneyResource , not WorkJourney

2 / To enable null, just add null=True, blank=True

Here is the corrected code:

 class EmployeeResource(ModelResource): journey = fields.ForeignKey(WorkJourneyResource, 'work_journey', null=True, blank=True) ....
