django - 如何通过额外的 kwargs 在 django 模型集工厂中形成？

Question

我如何将额外的 kwargs 传递给 modelformset 工厂中的 django modelform

例如，我想在详细 View 中禁用所有表单字段。

表格.py:

class ConceptForm(forms.ModelForm):

  class Meta:
    model = app_models.Concept
    fields = '__all__'

  def __init__(self, *args, **kwargs):

    self.action = kwargs.pop('action', None)

    super(ConceptForm, self).__init__(*args, **kwargs)

    if self.action is not None:
      if self.action == 'detail':
        for field in self.fields:
          self.fields[field].widget.attrs['readonly'] = True

View .py

modelformset = modelformset_factory(
  model = model,
  fields = show_fields,
  form = ConceptForm(kwargs={'action': 'detail'), <-- I would like something like this
)

错误是:

'ConceptForm' object is not callable

没有调用 init 未显示错误，但未禁用表单字段

modelformset = modelformset_factory(
  model = model,
  fields = show_fields,
  form = ConceptForm
)

正如 Passing custom parameters to formset forms section of the documentation 中指定的那样，您可以使用 form_kwargs=… FormSet 的参数:

ConceptFormSet = modelformset_factory(
    model = Concept,
    form = ConceptForm,
    fields = show_fields
)
formset = ConceptFormSet(form_kwargs={'action': 'detail'})
