  如果您的实例是现有的，而不是内联形式，则可以在模型表单中执行以下操作：

  def __init__(self,*args,**kwargs):
      super (AppointmentForm,self ).__init__(*args,**kwargs) # populates the post
      #filter appointments based on status
      if self.instance.pk:
          # the location filter below is a guess. i don't know your models.
          locations = Location.objects.filter(status_id=self.instance.status_id)
          self.fields['location'].queryset = locations
  

  另一种方法是使用Callbacks变得更加棘手......
