Django中的-success_url配置不正确 [英] Improperly Configured -success_url in Django

问题描述

我对success_url遇到了问题，而不是站点，我看到配置不正确的TemplateResponseMixin需要定义"template_name"或实现"get_template_names()".这是我的views.py:

I've got problem with success_url, rather then site I see an ImproperlyConfigured TemplateResponseMixin requires either a definition of 'template_name' or an implementation of 'get_template_names()'. Here is my views.py:

class CarRentView(SuccessMessageMixin, CreateView):
    form_class = CarRentForm
    success_url = reverse_lazy('cars')
    success_message = "You rent a car"

我的models.py:

my models.py:

class Rental(models.Model):
    rentus = models.ForeignKey(User, null=True)
    rentcar = models.ForeignKey(Car, null=True)

和forms.py:

CarRentForm类(forms.ModelForm):

class CarRentForm(forms.ModelForm):

class Meta:
    model = Rental
    fields = '__all__'

和我的网址:

url(r'^car/rent$', CarRentView.as_view(), name = 'rent'),

我想要租房后用户在车位上看到成功消息.

I want to after rent user will see sucess message on carsite.

推荐答案

成功提交表单后，您将重定向到名为 cars 的URL.您尚未显示此视图，但是错误消息告诉您尚未为其设置 template_name .您应该添加如下内容.

After the form is successfully submitted, you are redirecting to the url named cars. You haven't shown this view, but the error message is telling you that you haven't set template_name for it. You should add something like the following.

class CarView(...):
    template_name = 'cars.html'
