Django - Sorting posts by categories
I have two models -BlogPost and PostTopic. I would like to be able to filter by topic and see all the posts for that topic. This is working when I load up each url directly (i.e blog/cat/1), however when linking to this from the main blog post list view, I have tried the below template code: {% for topic in object_list %} <li><a href="{% url 'blog:BlogPostTopic_list' pk=topic.pk %}">{{ topic.topic }}</a></li> {% endfor %} However this doesn't work as it iterates over each topic mapped to the post (resulting in duplicates), rather than each unique topic. How do I link just to the unique topic page? models.py class PostTopic(models.Model): top_name = models.CharField(max_length=264, unique=True) def __str__(self): return self.top_name class BlogPost(models.Model): title = models.CharField(max_length=200) snippet = models.CharField(max_length=400, null=True) blog_pic = models.ImageField(upload_to='blog_pics', default='placeholder.jpg') hero_pic = models.ImageField(upload_to='blog_pics',blank=True) content = models.TextField() topic = models.ForeignKey(PostTopic, on_delete=models.CASCADE) create_date = models.DateTimeField(default=timezone.now) published_date = models.DateTimeField(blank=True, null=True) def get_absolute_url(self): return reverse("BlogPost_detail",kwargs={'pk':self.pk}) def __str__(self): return self.title views.py class BlogPostListView(ListView): model = BlogPost paginate_by = 4 def get_queryset(self): return BlogPost.objects.all().order_by('-published_date') class BlogPostDetailView(DetailView): model = BlogPost class BlogPostTopicListView(ListView): model = BlogPost template_name = 'blog/post_category.html' def get_queryset(self): return BlogPost.objects.filter(topic=self.kwargs['pk'] ) url url(r'^$',views.BlogPostListView.as_view(),name='BlogPost_list'), url(r'^(?P<pk>\d+)$',views.BlogPostDetailView.as_view(),name='BlogPost_detail'), url(r'^cat/(?P<pk>\d+)$',views.BlogPostTopicListView.as_view(), name='BlogPostTopic_list'), -
Who to display image in Django
I'm very new to Django so I saved an image into the database inside my models.py class Article(models.Model): title = models.CharField(max_length=120) content = models.TextField() active = models.BooleanField(default=True) picture = models.ImageField(upload_to='documents/pictures', null=True) now I want to display this image and I used the get_absolute_url method to get the current data from a row inside the db: def get_absolute_url(self): return f'/blog/{self.id}' In the views.py I return a renderfun with the params 'article':get_object_or_404(Article, id=my_id). Now in my template index.html I have this {% block content %} {{ article.content }} <img src="{{ article.picture }}" style="width: 200px; height: 200px;" /> {% endblock %} But if I open the developer console in chrome the img path is the same I set in models.py. The document/pictures folder is at the root of the django app. I tried to move it into the current app (Blog) but this also doesnt work. Do I have to set the media path in the settings.py ? I use django 3 and sqlite3 as db -
customize registration form in django
I created a registration form in django with blow codes forms.py: class UserFormRegistration(UserCreationForm): username = forms.CharField(label = 'نام کاربری') email = forms.EmailField(required=True, label = 'ایمیل') password1 = forms.CharField(label= 'رمزعبور', widget = forms.PasswordInput, strip = False) password2 = forms.CharField(label= 'تکرار رمز عبور', widget = forms.PasswordInput, strip = False) class Meta: model = User fields = ["username", "email", "password1", "password2"] views.py: def register(request): if request.method == "POST": form = UserFormRegistration(request.POST) if form.is_valid(): user =form.save() username = form.cleaned_data.get("username") login(request, user) messages.success(request, f"تبریک! اکانت شما با نام {username} با موفقیت ساخته شد") return redirect ("/") else: form = UserFormRegistration() return render(request, "accounts/registration.html", {"form":form}) So now, when i try to register with this form in the website i get some error like: The two password fields didn’t match. Enter a valid email address. The password is too similar to the username. How can i change these errors? For example i want to change the language and i don't want third error at all -

Django prefetch_related() in ListView class based view
I have a simple blog with 2 models: one for Post and one for Comment, like so: class Post(models.Model): title = models.CharField(max_length=100) # content = models.TextField() content = RichTextUploadingField(blank=True, null=True, config_name='claudiu_cfg') date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.title def get_absolute_url(self): return reverse('post-detail', kwargs={'pk': self.pk}) class Comment(models.Model): author = models.CharField(max_length=20) text = models.TextField(max_length=350) date_posted = models.DateTimeField(default=timezone.now) post = models.ForeignKey(Post, on_delete=models.CASCADE) def __str__(self): return self.author I want to display all posts (paginated) and how many comments each have. My views.py: class PostListView(ListView): model = Post template_name = 'blog/home.html' context_object_name = 'posts' ordering = ['-date_posted'] paginate_by = 5 Just like this i was getting all posts, but now i want to access the Comment table with as little selects as possible. I know one way to do this is define a queryset and did it like this: class PostListView(ListView): model = Post template_name = 'blog/home.html' # <app>/<model>_<viewtype>.html context_object_name = 'posts' ordering = ['-date_posted'] paginate_by = 5 querryset = Post.objects.all().prefetch_related() However that does not access the Comment data. Then i tried to overrite the get_queryset() function hopping to get the desired result. Still no success. def get_queryset(self): posts = Post.objects.all().prefetch_related('pk__comment').all() comments = Comment.objects.all().prefetch_related('post') print(dir(posts)) print('---------------------') print(posts._prefetch_done) return posts.order_by('-date_posted') That still … -
iterating over <class 'django.http.request.QueryDict'>?
i am sending a post request via ajax to the django's backend.

Extending a ModelForm with a ForeignKey field that was previously excluded
I have the following model: class Watchman(models.Model): group = models.ForeignKey('groups.Group') name = models.CharField(max_length=64) And the following model form: class NewWatchmanForm(forms.ModelForm): class Meta: model = Watchman fields = ['name'] At the time the new Watchman is created, I do not know which group it belongs to, hence name is the only model field defined in NewWatchmanForm. However, once I do figure out the correct group it belongs to, I use this form to update the object with the appropriate group: class UpdateWatchmanForm(NewWatchmanForm): group = forms.ModelChoiceField(queryset=Group.objects.all()) class Meta(NewWatchmanForm.Meta): fields = NewWatchmanForm.Meta.fields + ("group",) I was curious if there might be a better way to reuse my NewWatchmanForm. Ideally, I'd like to avoid having to declare the group explicitly, something like this: class UpdateWatchmanForm(NewWatchmanForm): # group = forms.ModelChoiceField(queryset=Group.objects.all()) class Meta(NewWatchmanForm.Meta): fields = NewWatchmanForm.Meta.fields + ("group",) However, if I do that, I get this error: fields = NewWatchmanForm.Meta.fields + ("group",) TypeError: can only concatenate list (not "tuple") to list What is the correct way to subclass an existing ModelForm and include a ForeignKey field (without redefining forms.ModelChoiceField(...))? -

Django ORM: adding counter for all subclasses to (abstract) parent class
I am working on a restaurant app. I have different dish type classes (Pizza, Platter, etc) and in order to pass a dict or list (JSON-format) of ALL dishes to the JS-client, I was thinking of adding an (abstract) parent class Dish that would contain a counter or ID that identifies every dish (the aim being I can then use those ID's to access a large number of input fields and respective IDs in the html-form from the menu-page). Any ideas on the best way to do this? I tried using InheritanceManager(), but that doesn't work if my Dish class is abstract. If it is not abstract (which it should be, I'd say), I get a You are trying to add a non-nullable field 'dish_ptr' error. Not sure my whole approach even makes sense, but can't think of a better way to work with large HTML-forms with 50-100 input fields (menu items). -

Implementing Vue RESTful API calls in Django within Django Templates with Session Authentication
I have a Django project that requires page refreshes any time I want to update the content. Currently it uses the built in Django Class Based Views, which in turn use Templates. I want to start implementing some javascript calls to refresh tables/forms/modal windows with new data, mostly in response to button clicks. I'm trying to use Vue to accomplish this, and I have created a Django REST Framework backend to facilitate this. I got a simple 'Hello world' vue class working where the data is hard coded into the data field of the Vue class. I can't seem to make the jump to getting data from the API though. I am getting an Unauthorized response. I have unit tests where I call the API from the DRF APITestCase using the self.client.get('api/path') and they work as expected (unauthorized when there is no authenticated user attached to request, authorized when there is). I have debugged into the DRF Permission class to see why the request is being refused and it is because there is no authenticated User attached to the request. I have added SessionAuthentication to the DEFAULT_AUTHENTICATION_CLASSES in settings. My question is, how do I add an authenticated user to … -
Route to different databases depending on the group of users in Django Rest Framework
I have a project with Django rest framework as backend and Vue as frontend and everything works well. Now, I have to extend my project. I want to bring the same product, but to a new group of users, who will have 0 interaction with the first group of users. No data will be shared among the two groups of users. Like if I created a copy of my backend with a new database and directed the new group of users to this new backend. So, I am looking for a solution not to have to build another backend for each new independent group of users (which is obviously less than ideal). I could create permissions where users could only access data about their own group and change every querysets. But I think it is not optimal to keep everyone on the same table as the number of groups of users will grow. I guess the ideal would be to have 1 database per group of users, 1 backend in total, and to route users to their own group specified by the api call they make with a /groupID/rest-of-endpoint Is that possible in Django ? Do you see any solution … -

duplicated lines are fetched by filter
I have a little bit complex combination of | & filter like this. objs = objs.annotate(num_line=Count("lns")).filter(Q(lns__id__in=lnIds) | (Q(sts__id__in=oIds) & (Q(lns__id__in=lnIds) | Q(num_ln__lte=0)))) It looks like work, but results are sometimes deplicated (has same id). id 1 2 3 3 4 5 I thought filter is assured to return unique id though ,am I wrong?? Or is it possible to omit duplicated rows?? class Obj(models.Model): created_at = models.DateTimeField(null=True) lns = models.ManyToManyField(Ln) sts = models.ManyToManyField(St) is = models.ManyToManyField(Is) pub_date = models.DateTimeField('date published') -

How to connect websocket after set up with NGINX and Supervisor?
I created a Django Channel beside my wsgi application. Everything works fine if I run: daphne -b 0.0.0.0 -p 8001 myapp.asgi:application I can connect to the websocekt but after I created supervisor with nginx I can not connect and I don't see any useful log that could solve the problem. When I check the supervisor status it has no error: asgi:asgi0 RUNNING pid 23981, uptime 0:10:22 asgi:asgi1 RUNNING pid 23980, uptime 0:10:22 asgi:asgi2 RUNNING pid 23983, uptime 0:10:22 asgi:asgi3 RUNNING pid 23982, uptime 0:10:22 The socket was originally localhost:8001 and I also allowed UFW to use that port but it didn't work so I changed to my server IP.
