2. 与大宗大宗大宗大宗古通式的关系的对立面
原标题:Edit the opposite side of a many to many relationship with django generic form

我有两个模式:

 class Actor(models.Model):
     name = models.CharField(max_length=30, unique = True)
     event = models.ManyToManyField(Event, blank=True, null=True)

 class Event(models.Model):
     name = models.CharField(max_length=30, unique = True)
     long_description = models.TextField(blank=True, null=True)

在前一个问题: Django表格将2个模型与许多领域连接起来:

class EventForm(forms.ModelForm):
      class Meta:
            model = Event

      def save(self, commit=True):
            instance = forms.ModelForm.save(self)
            instance.actors_set.clear()
            for actor in self.cleaned_data[ actors ]:
                instance.actors_set.add(actors)
            return instance

这使我能够从界定的平方米连接的另一方中增加m2的链接。

现在,我要ed开这一句子。 一、使用一般功能:

def generic_edit(request, modelname, object_id):
       modelname = modelname.lower()
       form_class = form_dict[modelname]
       return update_object(request,
            form_class = form_class,
            object_id = object_id,
            template_name =  createdit.html 
       )

但是,这一节奏已全部从S.C.R.C.R.C.C.C.C.R.C.R.C.C.C.R.C.C.R.C.C.R.C.C.C.R.C.C.R.C.C.R.C.C.R.C.C.R.C.C.C.R.C.C.R.C.R.C.C.R.R.C.R.C.R.C.R.C.R.R.C.R.C.R.R.C.R.R.S.R.R.R.R.R.R.R.S.S.R.R.R.S.S.S.R.R.R.S.R.R.R.R.R.R.S.S.R.R.S.S.S.S.S.S.S.S.S.S.S.S.S.S.S.S.S.R.R.S.R.R.R.S.S.R.

我认为,我需要做一些类似的事情:。 编辑M2M的两边:,但我有点照此。

我如何使用通用的更新——取决于许多到许多链接的另一方是否愿意?
