python - 动态更新ModelForm的Meta类模型字段

Question

def SiteAdminForm(model_cls, *args, **kwargs):
    class MerchantAdminForm(forms.ModelForm):
        class Meta:
            exclude = ('external_links', 'published', 'logo','image_zip_file',)
            model = model_cls

        def __init__(self, *args, **kwargs):
            super(MerchantAdminForm, self).__init__(*args, **kwargs)

    return MerchantAdminForm()

# In use...
merchant_form = SiteAdminForm(merchant.__class__, instance=merchant)

无论传入 model_cls 的内容是什么，模型始终会被忽略。

Meta.exclude设置正确，如何动态更新Meta.model？

Answer 1

def get_form(model_class):
    class DynamoForm(forms.ModelForm):
        class Meta:
            model = model_class

    return DynamoForm


form_set = get_form(ActualModel)(request.POST)

这就是你想要的吗？
