Django Admin - get_form覆盖

Question

我想在admin.py中覆盖get_form方法。我写了这段代码：

def get_form(self, request, obj=None, **kwargs):
    form = super(InactiveSiteAdmin, self).get_form(request, obj, **kwargs)
    form.base_fields['category'].widget.can_add_related = False
    form.base_fields['subcategory'].widget.can_add_related = False
    form.base_fields['category1'].widget.can_add_related = False
    ...
    ...
    form.base_fields['category'].widget.can_change_related = False
    return form

是否可以覆盖一行中的所有字段？：

form.base_fields[ALL_FIELDS].widget.can_add_related = False

Answer 1

看看循环是否有效，例如：

def get_form(self, request, obj=None, **kwargs):
    form = super(InactiveSiteAdmin, self).get_form(request, obj, **kwargs)
    for field in form.base_fields.keys():
        form.base_fields[field].widget.can_add_related = False
    return form
