提问我正在学习django/python，并被一个问题给卡住了。我有一个视图：create_document.py，我想在其中计算模型类NameDetails中的名字细节数量。但我不知道正确的写法！这是我models.py的代码：class NameDetails(FillableModelWithLanguageVersion): user = models.ForeignKey(User) name_details_prefix_title = models.CharField(null=True, blank=True, max_length=25) name_details_first_name = models.CharField(null=False, blank=False, max_length=50) name_details_middle_name = models.CharField(null=True, blank=True, max_length=100) ....这是我create_document.py的代码，里面用到了django wizard。我想要确定的是用户在他们能够创建文档前，至少有一个名字。from app_name.core.models import NameDetails class CreateDocumentWizard(SessionWizardView): template_name = 'documents/document_create.html' form_list = [ core_forms.CreateDocumentWizardForm01, core_forms.CreateDocumentWizardForm02, core_forms.CreateDocumentWizardForm03, core_forms.CreateDocumentWizardForm04, ] def get_form_kwargs(self, step=None): kwargs = super(CreateDocumentWizard, self).get_form_kwargs(step) kwargs.setdefault('user', self.request.user) return kwargs def get_context_data(self, form, **kwargs): name_details_count = NameDetails(user=self.request.user).count() if name_details_count < 1: return redirect(settings.MENU_DETAIL_LINK_NAME_DETAILS)当我使用name_details_count = NameDetails(user=self.request.user).count()确定用户的NameDetails计数时，我得到了以下错误：NameDetails' object has no attribute 'count'我已经尝试了很多种组合，但现在还是卡住了。回答1你的get_context_data函数应该这样写：name_details_count = NameDetails.objects.filter(user=self.request.user).count()回答2眼下你正在以request.user为用户创建一个全新的NameDetails实例。相反，你应该查询数据库中当前用户已有的NameDetails，并对他们进行计数。你可以通过NameDetails.objects查询数据库：name_details_count = NameDetails.objects.filter(user=self.request.user).count()内容来源于StackOverflow, 遵循 CCBY-SA 4.0 许可协议进行翻译与使用。原文链接：django object has no attribute 'count'
