我有一个简单的ModelForm:

class MyForm(ModelForm):

    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        del self.fields['name']

正如您所看到的,我尝试从表单的字段列表中删除一个字段(该字段明确存在于模型中),但我得到一个例外:

TemplateSyntaxError at [..]

Caught an exception while rendering: "Key 'name' not found in Form"

我没有写自定义表单,因此发生错误的模板是:

/templates/admin/includes/fieldset.html, error at line 4

有任何想法吗？
