views.py

class ResumeDetialView(View):
    template_name = 'cv/resume-detial.html'
    
    def get(self, request, resume_id, resume_slug):

ResumeDetial matching query does not exist.

I am a beginner and thank you for your help

You are doing ResumeDetial.objects.get(pk=project_id, slug=projects_slug) while the ResumeDetial with these criteria doesn't exist. You can use filter to search for ResumeDetial's with the given criteria, in case no results are found, it will return an empty list.

So, you can change this part of the code:

    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})
