fields = ['first_name', 'last_name', 'birth_date']
user__first_name, user__last_name, birth_date = self.fields.get(fields)

由于self.fields是词典，因此无法执行此操作。如何修改它使其起作用？

    198     def check_user__first_name_user__last_name_birth_date(self):
    199         import ipdb; ipdb.set_trace()
    200
--> 201         fields = ['first_name', 'last_name', 'birth_date']
    202         user__first_name, user__last_name, birth_date = self.fields.get(fields)
    203         for m in self._check(CustomerProfile, user__first_name=user__first_name,
    204                              user__last_name=user__last_name,
    205                              birth_date=birth_date):
    206             self._match(m.user, _('Same first name, last name and birth date.'),
    207                         fields, ', '.join(map(str, self.fields.get(fields))))

最佳答案

由于self.fields是字典，因此您需要的内容等同于：

user__first_name, user__last_name, birth_date = (self.fields.get("first_name"),
                                                 self.fields.get("last_name"),
                                                 self.fields.get("birth_date"))

因此，例如，使用列表推导：

fields = ['first_name', 'last_name', 'birth_date']
user__first_name, user__last_name, birth_date = [self.fields.get(x) for x in fields]
