Hi, I'm trying to change the default value of a foreignkey-formfield to set a Value of an other model depending on the logged in user. But I'm racking my brain on it...

This: Changing ForeignKey’s defaults in admin site would an option to change the empty_label, but I need the default_value.

#Now I tried the following without errors but it didn't had the desired effect:
class EmployeeAdmin(admin.ModelAdmin):
...
  def formfield_for_foreignkey(self, db_field, request=None, **kwargs):
    formfields= super(EmployeeAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs)

    if request.user.is_superuser:
        return formfields
    if db_field.name == "company":
        #This is the RELEVANT LINE
        kwargs["initial"]  = request.user.default_company

    return db_field.formfield(**kwargs)


admin.site.register(Employee, EmployeeAdmin)

from django.contrib.auth.models import User, UserManager
class CompanyUser(User):
    ...
    objects = UserManager()
    company = models.ManyToManyField(Company)
    default_company= models.ForeignKey(Company, related_name='default_company')
    #I registered the CompanyUser instead of the standard User, 
    #   thats all up and working
    ...

class Employee(models.Model):
    company = models.ForeignKey(Company)
    ...

Hint: kwargs["default"] ... doesn't exist.

Thanks in advance, Nick
