Django - Is it better to store user information by customising the default User model, or should I create a separate Model for this?
This is for a practice project I am building to learn Django. The site will need to track certain data about the user. Should I customise the default User model? Or create a new model like - class UserData(models.Model): '''holds user info''' owner = models.ForeignKey(User) # data I couldn't find a clear answer. -
How to delete a django object from multi-form button submission?
Im working on a django app and im fairly sure ive got this wrong but i cant workout how to delete a django object from a form button. Ive got the edit/update fields working but im not sure how to use the same form (or the one below it) to also process a delete. my experience with django is limited and i havent setup the logging yet properly. Ive tried the below. What am i doing wrong? the Model: class Tier(models.Model): number = models.PositiveSmallIntegerField(default=0) description = models.TextField(max_length=800, verbose_name='Description') price = models.IntegerField(verbose_name='Price') can_message = models.BooleanField(default=False) user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='tier_user') def __str__(self): return 'Tier ' + str(self.number) def save(self, *args, **kwargs): amount = Tier.objects.filter(user=self.user).count() self.number = amount + 1 return super().save(*args, **kwargs) def delete(sender, instance, *args, **kwargs): tier = instance tier.delete() EditTierForm: <div> <form method="post" action="" role="form" class="col s12"> <h4>Edit Tier</h4> {% csrf_token %} <div class="input-field col s12"> ... </div> <div class="input-field col s12>"> <button class="btn waves-effect waves-light" type="submit" name="action">Save <i class="material-icons right">add</i> </button> </div> </form> <form action="{% url 'tier_delete' tier_id=tier.number %}" method="delete" role="form" class="col s12"> {% csrf_token %} <div class="input-field col s12>"> <button class="btn waves-effect waves-light btn red" type="submit" name="action">Delete Tier <i class="material-icons left">delete</i> </button> </div> </form> </div> urls: path('mytiers/', … -
TypeError when trying to create a model instance
I have a project where I need to create a Django command to upload multiple images at a time. I have a base class Image that defines the file, and subclass Icon that associates a word and a description to the icon. My issue is that I get an error when I call Icon.objects.create().

Accessing profile info through user model Django
Hello I am a beginner with the django python framework. I need to display a user's image and bio on a file named user_posts.html in my blog app. I have it where I can access the user's image and bio by looping over the posts for the user. However, I need it so it only displays the bio and the image once. I have a separate profile.html in a users app. In that file, I can do just src="{{ user.profile.image.url }}" and {{ user.profile.bio }} to access the users information but that does not seem to work in my user_posts.html because of the structure of my project. I can't figure out how to tell the for loop to just go over once to access the users information. users_post.html {% extends "blog/base.html" %} {% block content %} <hr size="30"> <div class="row"> <div class="column left"> {% for post in posts %} <img style= "float:left" src="{{ post.author.profile.image.url}}" width="125" height="125"> <h5 style="text-align: left;">{{ post.author.profile.bio }}</h5> {% endfor %} </div> views.py class UserPostListView(ListView): model = Post template_name = 'blog/user_posts.html' # <app>/<model>_<viewtype>.html context_object_name = 'posts' ordering = ['-date_posted'] paginate_by = 5 def get_queryset(self): user = get_object_or_404(User, username=self.kwargs.get('username')) return Post.objects.filter(author=user).order_by('-date_posted') models.py from django.db import models from django.contrib.auth.models … -

Very slow django with "large" database (< 1M rows)
I'm trying to build an app with django. When I work with a small database (around 10k rows), the app works perfectly. However, in some views, I need to calculate some data of my classes, so I need to call all of my database. It is very slow (more than 30s), and according to Django Debug Toolbar, most part of the time is consumed by CPU. Here's an example of a (very) simplified code I try to launch: def test_view(request): queryset_articles = Articles.objects.all() total_count = sum([a.words_count for a in queryset_articles]) response = 'Total words : ' + str(count) return HttpResponse(response) How should I do to get a reasonable waiting time? I think about doing another table, which I would update frequently with these historical stats, then call them directly in my view. Thank you, Pierre -

How to add error messages in login and registration form in Django
I am creating a website with Django. I want to add an error message to the login and registration form, so if I click on the login / register button and have some fields filled in incorrectly or the username is already in use, a message will appear below each form field. I've already tried form.errors, but I couldn't style it with CSS and I also couldn't edit the text that showed up when I filled in some field wrong.

How can I configure Flask to behave like Django?

Django to return a view with TokenAuthentication for WebView
I am trying to create a flutter app which will use webview to display authenticated data from my Django App. Steps Involved: Flutter app sends authentication request Django validates the user credentials (user id & Password) and returns authtoken Flutter then sends a request via a webview to a url (which requires login). I would like to login the user in webapp using this token and return the webview. If the url does not require authentcation, it works like a charm. When the url requires authentication, I am redirected to the login page and I want users to bypass that using token authentication which is already aquired in Step 1 here is my Django view. class QuizTake(FormView): permission_classes = (IsAuthenticated,) form_class = QuestionForm template_name = 'question.html' result_template_name = 'result.html' single_complete_template_name = 'single_complete.html' login_template_name='login.html' def dispatch(self, request, *args, **kwargs): self.quiz = get_object_or_404(Quiz, url=self.kwargs['quiz_name']) print(self.kwargs['quiz_name']) """ Authenticate if the request has token authentication """ if self.quiz.draft and not request.user.has_perm('quiz.change_quiz'): raise PermissionDenied try: self.logged_in_user = self.request.user.is_authenticated() except TypeError: self.logged_in_user = self.request.user.is_authenticated if self.logged_in_user: self.sitting = Sitting.objects.user_sitting(request.user, self.quiz) else: self.sitting = self.anon_load_sitting() if self.sitting is False: print("sitting false") if self.logged_in_user: return render(request, self.single_complete_template_name) else: redirecturl = "/login/?next=/quiz/"+self.kwargs['quiz_name']+"/take/" return redirect(redirecturl) return super(QuizTake, self).dispatch(request, *args, **kwargs) … -
Django sqlite3 migration for trigger failing with "OperationalError: incomplete input" despite functional SQL code
I wanted to implement a trigger in a hobby project of mine which uses an sqlite3 database. For this purpose I wrote a custom-migration that runs custom-sql code. When trying to execute this specific trigger, the migration fails with the stacktrace below. What is odd however is that at the same time: The SQL Code for the trigger on its own works fine. When I execute it directly on the database (through sqlitebrowser), there is no error (see the specific query in migration file below) and the trigger shows up as expected. The migration process on its own works fine. I was able to migrate with the migration file shown below as long as I swapped out the migration.RunSQL code for that of a much simpler trigger also shown below. It is only when I use the two together that I get an error. Given that the code of the migrations.RunSQL call itself (as the only variable left) also looks perfectly fine to me, I am at a bit of a loss. What am I doing wrong? SIDENOTE: If there are ways of writing triggers inside of Django, I would welcome them, but still rather get this way to work … -

Prevent superuser account from logging into django website
I have encountered a problem in Django. When I login into Django admin using the superuser account and reload the actual website the superuser also gets logged in into the website rather than only admin page (I guess its a normal behavior as superuser is also a user). How do I prevent the superuser from being logged in into website. def user_login(request): resp = dict() if request.method == "POST": login_username = request.POST.get('uname') login_password = request.POST.get('password') user = authenticate(username=login_username, password=login_password) if user is not None and login_username != 'ruturajK': login(request, user) resp['invaliduser'] = False resp['redirect'] = True resp['message'] = "" else: resp['invaliduser'] = True resp['redirect'] = False resp['message'] = "Invalid Credentials" return HttpResponse(json.dumps(resp), content_type="application/json") return HttpResponse("404 not found") The account ruturajK is a superuser account Superuser also logged in into website This function is called by the url in urls.py path('login', views.user_login, name='login') I have also seen that when I login using any other account(nonstaff) I cant login into backend Nonstaff user I see this after reloading admin page -

Django get True/False if field has data
In a Django queryset I have the following: class Address(models.Model): building town geo_lat geo_lng queryset = Address.objects.all() What i want to do is return True or False field if both geo fields are set.

I dont want to filter out any, but add an extra field I can use to test if true or false) -
Django gives errors when running the server
