Django Change继承表单元类 [英] Django Change inherited form meta class

问题描述

我想编辑一个从 ModelForm 继承其数据的表单的元类。我只想添加一个字段，我不想重复所有表格。

I want to edit the Meta Class of a form that inherits its data from a ModelForm. All I want is to add one field, I don't want to repeat all the form.

# NuevaBibliotecaCompartida is a ModelForm

class EditarBibliotecaCompartida(NuevaBibliotecaCompartida):

    class Meta:
        fields = ('nombre', 'direccion', 'imagen', 'punto_google_maps')

我收到错误 ModelForm没有指定模型类，当然，因为添加字段时我将覆盖Meta类。我该如何解决呢？

I get the error ModelForm has no model class specified, of course, because I am overriding the Meta class when I add a field. How can I solve this?

推荐答案

您需要明确地将父级的元子类化。 c> class：

You need to explicitly subclass the parent's Meta class:

class Meta(NuevaBibliotecaCompartida.Meta):
    # `model` will now be inherited
    fields = ('nombre', 'direccion', 'imagen', 'punto_google_maps')
