基于多个泛型类的DetailView's表示相同型号

Question

我正试图使用两个细节视图，它们将在不同的URL上为同一模型呈现不同的模板。同一个模型是否可以有不同的通用局部视图？如果没有，我想我只能自己写了。我所有的细节视图都会路由到absoluteur，但在这种情况下，我希望每个细节视图都路由到我在类中定义的模板。

我使用下面的方法成功地创建了多个列表视图和更新视图，但它对细节视图不起作用，我总是以"course_detail"；尽管我宣称"；课程细节制作者视图">

class Course(models.Model):
class Meta:
verbose_name = "Course"
verbose_name_plural = "Courses"
ordering = ['start_time']
pub_partner_choices = [
("company1", "company1"),
('company2', 'company2'),
]
status_choices = [
('hold', 'Hold'),
('editorial', 'Editorial'),
('approved', 'Approved'),
('cancelled', 'Cancelled'),
]
title = models.CharField(max_length=200)
slug = AutoSlugField(max_length=100, help_text="course title",
populate_from=['title', 'date'], unique=True, )
start_time = models.TimeField(blank=True, null=True)

def get_absolute_url(self):
"""Return URL to detail page of a Course"""
return reverse(

我的问题是由使用reverse_lazy获取absolute_url的UpdateView引起的。事实证明，DetailViews没有问题，只是我试图访问它们的方式(哇！(解决方案是覆盖get_success_url((。现在更正的UpdateView如下所示：

class CourseUpdateProducerView(LoginRequiredMixin, UpdateView):
form_class = CourseFormProducerView
model = Course
template_name = 'lots_app/course_form_producer_view.html'
extra_context = {"update": True}
def get_success_url(self, **kwargs):
"""Return the URL to redirect to after processing a valid form."""
url = reverse_lazy('course_detail_producer_view',
kwargs={"slug": self.object.slug})
return url
