django-admin formfield_for_* change default value per/depending on instance
- by Nick Ma.
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
