How to compare multiple lists in order in django template
I have an "Educate" class model, which consists of fields such as class name, class description, and the teacher in charge of the class. And I have a "History" class model, which is written to the database whenever the contents of the "Educate" class change. Every time the teacher in charge of Educate changes, it is tracked in the "History" class model, and what I want to get is the duration of each teacher. The "History" class model has a "summary" field, in which the contents of the changed fields are stored. If I check in DB, it is as below, and you have to load json format from template to output as string. DB: {"field_summary": {"teacher": "\ub...json...9bc -> \ub...json...9c", "contact": "010-1111-1111-> 010-0000-0000"}, "file_summary": {}} [educate/models.py] class Educate(models.Model): educate_name = models.CharField(max_length=2000, null=True) educate_explanation = models.CharField(max_length=2000, null=True) teacher = models.ManyToManyField(Contact, related_name="teacher") @property def history(self): history = self.history_set.all().order_by('-create_date') for h in history: setattr(h, 'summary_json', json.loads(h.summary)) return history class History(models.Model): educate = models.ForeignKey(Educate, on_delete=models.SET_NULL, null=True, blank=True) summary = models.TextField(blank=True, null=True) create_date = models.DateTimeField(auto_now_add=True) def json(self): return { 'id': self.id, 'educate': { 'id': self.educate.id, 'educate_name': self.educate.educate_name, 'educate_explanation': self.educate.educate_explanation, }, 'summary': self.summary, 'create_date': self.create_date } [educate/views.py] def statistic(request): educate = Educate.objects.get(id='117') return render(request, 'statistic.html', {'educate': … -

Django - Left Click on the link not working but right click with new tab works
I have a DropDown Menu in my Navbar which shows the recent Notifications for the user.

database does not exist postgresql

Is there a way to use both UserPassesTestMixin and PermissionRequiredMixin?
I'm trying to create a moderator using Django class-based views in my blog app. It uses the UserPassesTestMixin to prevent other users from editing content that's not theirs. What I'm trying to implement is a group called Manager that has change_blog permissions and I am using PermissionsRequiredMixin in views.py Here is my code so far class UserAccessMixin(PermissionRequiredMixin): def dispatch(self, request, *args, **kwargs): if (not self.request.user.is_authenticated): return redirect_to_login(self.request.get_full_path(), self.get_login_url(), self.get_redirect_field_name()) if not self.has_permission(): return redirect('/') return super(UserAccessMixin, self).dispatch(request, *args, **kwargs) class IssueUpdateView(LoginRequiredMixin, UserPassesTestMixin, UserAccessMixin, UpdateView): raise_exception = False permission_required = 'issues.change_issue' model = Issue fields = ['title', 'content', 'mark_as', 'assignee'] def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) def test_func(self): issue = self.get_object() if self.request.user == issue.author: return True return False When I test this code out as written, the permissions don't work and I get a 403 error page, but everything else functions normally. However, if I delete UserPassesTestMixin and leave PermissionRequiredMixin in, it works but then new problems arise. The original poster can no longer update their own post but when a mod user updates the post, it completely overwrites everything as if the mod user was the original poster. Is there a way to tweak either UserPassesTestMixin or …
