Question

嗨，这是我的项目，我需要在我的项目中定义两个 get_absolute_url get_absolute_url一个

models.py

def get_absolute_url(self):
    return reverse("cv:resume_detial", args={self.id, self.slug})

urls.py

path('resume-detial/<int:resume_id>/<slug:resume_slug>', views.ResumeDetialView.as_view(), name="resume_detial"),

views.py

class ResumeDetialView(View):
    template_name = 'cv/resume-detial.html'
    
    def get(self, request, resume_id, resume_slug):
        resumes = ResumeDetial.objects.get(pk=resume_id, slug=resume_slug)
        return render(request, self.template_name, {'resumes':resumes})

这是一部作品但是其他的get_absolute_url是不行的

models.py

def get_absolute_url(self):
    return reverse("cv:project_detial", args={self.id, self.project_slug})

urls.py

path('project-detial/<int:project_id>/<slug:projects_slug>', views.ProjectDetialView.as_view(), name="project_detial"),

views.py

class ProjectDetialView(View):
    template_name = 'cv/project-detial.html'
    
    def get(self, request, project_id, projects_slug):
        projects = ResumeDetial.objects.get(pk=project_id, slug=projects_slug)
        return render(request, self.template_name, {"projects":projects})

django 消息

DoesNotExist at /project-detial/1/todo-django
ResumeDetial matching query does not exist.

我是初学者，感谢您的帮助

你正在做ResumeDetial.objects.get(pk=project_id, slug=projects_slug) 而具有这些条件的 ResumeDetial 不存在。您可以使用 filter 来搜索符合给定条件的 ResumeDetial，如果没有找到结果，它将 return 一个空列表。

因此，您可以更改这部分代码：

    def get(self, request, project_id, projects_slug):
        projects = ResumeDetial.objects.filter(pk=project_id, slug=projects_slug)
        return render(request, self.template_name, {"projects":projects})
