Override save method in Django not working
My goal with the following code is to create an athlete object and override the save method to automatically set the category for a given athlete based on the born_date. The Category class will be inherited in other models too. The list within the class serves as validation purposes for the save method and the tuples for choice fields (used in other models). Although everything seems right, I ran some test in the shell and the code is saving whatever born_date is inputed. Why is that the case? Can someone shed some light on the problem? Thanks from django.db import models from datetime import datetime class Category: list_categories = [ 'u12', 'u13', 'u14', 'u15', 'u16', 'u17', 'u18', 'u19', 'u20', 'u21', ] CATEGORIES = [ ('U12', 'u12'), ('U13', 'u13'), ('U14', 'u14'), ('U15', 'u15'), ('U17', 'u17'), ('U19', 'u19'), ('U21', 'u21'), ] class Athlete(models.Model, Category): name = models.CharField(max_length=120) born_date = models.DateField() category = models.CharField(max_length=3) def save(self, *args, **kwargs): year_now = datetime.date.today().year year_born_obj = datetime.datetime.strptime(self.data_nascimento, "%Y-%m-%d") self.category = 'u{}'.format(year_now - year_born_obj.year) if self.category in Category.list_categories: try: super(Athlete, self).save(*args, **kwargs) except ValueError: print('Category does not exist.

Django rest deferred task
I want to write an API method that will do a specific task (e.g task/create) But this task takes a long time. I want the user to run the task (task/create) and then polled the service until it was executed (task/status). As soon as the task is completed, the user can request the result (e.g task/result). What tools can I use to implement such a pattern? Can I put the task on a separate thread? -

Django Ajax div not reloading/disappearing after posting comment
I am trying to resolve the problem for few days. I want to post the comment without refreshing page. The problem is the div in which comments are is not reloading or disappearing after hitting post button. It depends on how i "catch" it: when I use the id like: $('#comments').append('<p>' + data.comment.content + '</p><small>' + data.comment.author + '/' + data.comment.date_of_create + '</small>'); it is not reloading and if i use class it disappears. When i refresh the page, comment is being add properly.

Modify login view to use simple JWT
I am using Django REST framework with SimpleJWT. I am trying to let me user log in form use simpleJWT authentication. Roughly, I think my log in view should: Retrieve the username/password from the form, send a POST request to the TokenObtainPairView.as_view() view, collect the returned token and store it in local storage. How do I do that in my django code? Currently I only have a standard log in form that does not use JWT. Settings.py REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES' : ('rest_framework.permissions.IsAuthenticated',), 'DEFAULT_AUTHENTICATION_CLASSES': ('rest_framework_simplejwt.authentication.JWTAuthentication',),} My project urls: urlpatterns = [ path('admin/', admin.site.urls), path("", include("my_api.urls")), path('api-auth/', include('rest_framework.urls')), path('api/token', TokenObtainPairView.as_view()), path('api/token/refresh', TokenRefreshView.as_view()), ] This is the user login view. I think I should make a POST request to the 'api/token' with my username and password as my payload, get the returned token, and store it in local storage, but I dont know how to do that in Django. def login_view(request): if request.method == "POST": # Attempt to sign user in email = request.POST["email"] password = request.POST["password"] user = User.objects.get(email=email) if user.check_password(password): username = user.username user = authenticate(username=username, password=password) print("Login successful") login(request, user) return HttpResponseRedirect(reverse("welcome"))``` -
GDPR compliance for a web app (Vue.js, Django, Heroku)
I have build a web application using Django, Vue.js and deployed it on Heroku. It is a web application made for a big charity where you can win prizes by donating to the charity. The following information is collected: Name Username Email Password Which is pretty basic, I guess. The reason no payment information is stored is because, upon clicking 'Donate', the user is redirected to JustGiving (implemented the JustGiving API) where they enter their payment information and such and are then redirected back to our website. A few emails are sent: An email when somebody wins a prize An email if you are the winner of the prize An email when a new prize draw is taking place A receipt of your donation This will be the first time I properly publish a web application so wanted to ask what steps I need to ensure to make sure the web app is legal. I know I have to probably have a 'cookies' alert and a section where users choose to receive emails or not. What other steps must I take to make sure I am not breaking any rules? -

Django - changing value from db in place and save it to db
I have table on my page like that: And models.py like that: models.py class Book(models.Model): title = models.CharField(max_length=100) author = models.CharField(max_length=30) category = models.IntegerField() offset_pages = models.IntegerField() read_pages = models.IntegerField() total_pages = models.IntegerField() book_path = models.CharField(max_length=200, default='') status = models.BooleanField(default=False) def __str__(self): return f'{self.category} | {self.title} | {self.author}' I would like to click on value in "Read pages" column (404 in this case) and then modify it and save to database. The only way I see it for now is to make an html input there with assigned value of 404, then change it within an input and submit it with additional button. I know how to do so, but it seems to me like there has to be way better solution. Does any onemay present me another solution? -
Creating a navigation menu custom tag in Django
Please accept my apology if this is answered somewhere in the Django docs or stackoverflow, but I couldn't track it down myself! I'm creating a portfolio app - mainly as a project to learn Django, but also potentially as a gift to a relative to promote their illustration work and save them some money. I'm creating a custom tag to render a main navigation menu. I've tested django-treebeard and django-mptt, but they feel excessive for a project on this scale, so I'm relying on ForeignKey relationships in my Page model to define parent-child pages. At the moment, I can render a list of all parent pages and all child pages, but of course I want to filter child pages by their parent. Would really appreciate any guidance, whether I do the filter in the templatetags file or in the template itself. My menu_tags.py (in 'Templatetags' dir for the app): from django import template from django.views.generic import ListView from pages.models import Page register = template.Library() @register.inclusion_tag('menus/main_menu.html') def main_menu(): parent = Page.objects.filter(is_parent=True) child = Page.objects.filter(is_parent=False) return { 'parent': parent, 'child': child, } And my template: {% for parent in parent %} <p><strong>{{ parent.title }}</strong></p> {% for children in children %} <p>{{ children.title … -

Redirecting from the login page to signup page back to login page with the same parameters in the url in django
I may not have been descriptive in the title but what I want is that for example When a new user opens a page where login is required --> he is redirected to login page with the login url having a next parameter to the previous page.But as he is a new user he chooses to signup by clicking on a link on the login page which takes him to signup page ,now this is where the problem comes - The signup url gets no parameter and once user signs up he is automatically redirected to login page and after he logs in he is redirected to the index page instead of the page where login was required. This is my login view for my customer user model: def login(request): if request.user.is_authenticated: return redirect('/') else: if request.method == "POST": email=request.POST['email'] password=request.POST['password'] user=auth.authenticate(email=email,password=password) if user is not None: auth.login(request, user) next_page = request.POST['next'] if next_page != '': return redirect(next_page) else: return redirect('/') else: messages.info(request,"Email Password didn't match") next = request.POST['next'] if next != '': login_url = reverse('login') query_string = urlencode({'next': next}) url = '{}?{}'.format(login_url, query_string) # create the url return redirect(url) else: return redirect('login') else: return render(request,"login.html") And this is my … -
