我有一个表格，对于带有Many2Many的模型有一个选择多个选项。这似乎有效但在实际使用表单时，如果我选择多个内容并单击“保存”，则只保存其中一个项目。
他在views.py中的相关信息显示了这种情况发生的位置。
此外，事务的输出也在这里，看起来每次都在进行插入。我想我想要创造一个？虽然不确定我是否这样做（或如何）如果每次更改提供者所属的组时也会这样做。
输出：
(0.000) BEGIN; args=None
(0.001) DELETE FROM "ipaswdb_providerlocations" WHERE "ipaswdb_providerlocations"."provider_id" = 1; args=(1,)
here!IPANM
Made a location!
here!IPAABQ
Made a location!
(0.000) BEGIN; args=None
(0.000) INSERT INTO "ipaswdb_providerlocations" ("provider_id", "group_location_id", "created_at", "updated_at") VALUES (1, 2, '2016-10-04', '2016-10-04'); args=[1, 2, u'2016-10-04', u'2016-10-04']

您可以尝试从views.py
中的for循环中取出return语句def form_valid(self, form):
self.object = form.save(commit=False)
ProviderLocations.objects.filter(provider=self.object).delete()
for group_location in form.cleaned_data['group_locations']:
print("here!" + group_location.doing_business_as)
location = ProviderLocations()
print("Made a location!") #executes twice
location.provider = self.object
location.group_location = group_location
location.save()
print("Id: " + str(location.id)) #executes once
return super(ModelFormMixin, self).form_valid(form)
