我们从Python开源项目中，提取了以下21个代码示例，用于说明如何使用django.forms.forms.DeclarativeFieldsMetaclass()。
def obj_as_dict(o): if isinstance(o, DeclarativeFieldsMetaclass): o = FormSerializer(form=o).data if isinstance(o, forms.Field): o = FormFieldSerializer(field=o).data if isinstance(o, forms.Widget): o = FormWidgetSerializer(widget=o).data if isinstance(o, (list, tuple)): o = [obj_as_dict(x) for x in o] if isinstance(o, Promise): try: o = force_unicode(o) except: # Item could be a lazy tuple or list try: o = [obj_as_dict(x) for x in o] except: raise Exception('Unable to resolve lazy object %s' % o) if callable(o): o = o() if isinstance(o, dict): for k, v in o.items(): o[k] = obj_as_dict(v) return o
def get_widget_params_form(self, wizard): data = wizard.get_cleaned_data_for_step(wizard.steps.first) widget_type = data['widget_type'] widget = widget_manager.get(widget_type) fields = copy.deepcopy(widget.base_fields) if 'id' in fields: del fields['id'] return DeclarativeFieldsMetaclass("WidgetParamsForm", (forms.Form,), fields)
def test_valid_results_get_request(self): client = Client(enforce_csrf_checks=True) response = client.get('/results/', {'query': 'Frozen'}) self.assertEqual(response.status_code, 200) self.assertTrue(isinstance(response.context['form'], DeclarativeFieldsMetaclass))
