我试图改变一个foreignkey-formfield的 default value，以设置一个其他模型的Value *，具体取决于 * 登录的 * 用户 *。但我在绞尽脑汁...
Changing ForeignKey’s defaults in admin site是一个可以改变empty_label的选项，但是我需要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)
    ...

提示：kwargs[“default”].没有发现
谢谢你，尼克。
