Authentication to my app does not work when I deploy on heroku
Here is my code def connexion(request): if request.method == "POST": form = LoginForm(request.POST) if form.is_valid(): email = form.cleaned_data["email"] password = form.cleaned_data["password"] matricule = form.cleaned_data["matricule"] user = authenticate(email=email, password=password) if user is not None: user = User.objects.get(email=email) if Agent.objects.filter(user=user, matricule=matricule).exists(): agent = get_object_or_404(Agent, user=user) profile = agent.profile if user.is_active: login(request, user) request.session["profile"] = profile return redirect(reverse("elec_meter:home")) else: messages.add_message(request,messages.WARNING,"Votre profile n'est pas " "encore activé! Veuillez contacter l'administrateur.") return render(request, "elec_meter/login.html", {"form": form}) else: messages.add_message(request,messages.ERROR,"Utilisateur non existant !") return render(request, "elec_meter/login.html", {"form": form}) else: messages.add_message(request,messages.ERROR,"Utilisateur non existant !") return render(request, "elec_meter/login.html", {"form": form}) else: form = LoginForm() return render(request, "elec_meter/login.html", {"form": form}) This is the code that allows authentication to my app. It works very well locally. But when I deploy the application on heroku it doesn't work anymore. It always sends me back to the login page without any messages. Sometimes it sends me a 403 forbidden while I have {% csrf_token%} in the form. Are there any configurations to add ? How can I solve this problem ? -
Many-to-many relationship between 3 tables in Django
I have the following models: class Project(models.Model): project_name = models.CharField(max_length=50) project_users = models.ManyToManyField('Users.UserAccount', related_name='project_users', blank=True) .... class UserAccount(AbstractBaseUser, PermissionsMixin): username = models.CharField(max_length=30, unique=True) .... class Discipline(models.Model): name = models.CharField(unique=True, max_length=27, choices=discipline_choices) The DB table for project_users looks like this: *--------*----------------*---------------------* | ID | project_id | user_account_id | *--------*----------------*---------------------* I want to have an extra relationship in project_users field/table with the Discipline model. Is that possible in Django? I have been looking at intermediary-manytomany relationships in Django, but that's not exactly what I want. In my application, there are a set amount of disciplines, and what I'm trying to achieve is to give each user multiple disciplines in a single project. So something like this: *--------*----------------*---------------------*-------------------* | ID | project_id | user_account_id | discipline_id | *--------*----------------*---------------------*-------------------* Is this possible? -
Python (Django) how to assign a default value in case of error
Hey I'm using django in a project, using a POST method, the view in Django receives data, it works fine if the data is received but if no data is received I want to assign a default value instead of getting an error here is my code.

How to create a table using raw sql but manage it using django's ORM?
I am using django for my backend, and I want to use table partitioning and composite primary key for postgresql, but, django's ORM does not support these features yet (or at least I couldn't find them). So, I have decided to use raw sql code in django, but I would like to manage it using django's ORM (only the creation would be in raw sql, and this table would have many-to-many relationships with other tables). I would like to know if this is possible and if yes, what would be the best way to do it? Thank you in advance for your time. -
Django. How to return error 500 without sending mail to admins
I am using standard error handling in production - if there are server errors I am getting mails. However, on certain APIs I want to have a response with HTTP code 500 as part of the "valid flow". (It's done for some learning purposes) So my view for that looks like this: from rest_framework.response import Response from rest_framework import status def give_me_error(request): return Response("This is expected error", status=status.HTTP_500_INTERNAL_SERVER_ERROR) And what I want is not to get email of this particular response (because I wanted it to be 500) I've also tried this way: from django.http import JsonResponse def give_me_error(request): return JsonResponse({'error': 'expected error'}, status=status.HTTP_500_INTERNAL_SERVER_ERROR) But it also generates mail. Is there a way to have a view returning error 500 that will not trigger e-mail send? (without disabling the e-mail functionality system-wide) -
Invalid block tag on line 1: 'overextends'. Did you forget to register or load this tag?
I'm upgrading mezzanine/django application form python 2.7/Mezzanine 4.3.1 to python 3.7/mezzanine 5.0.0. When when running the application in 3.7/mezzanine 5.0.0. I get the error django.template.exceptions.TemplateSyntaxError: Invalid block tag on line 1: 'overextends'. Did you forget to register or load this tag? I guess it must come from the file myProject/myProject/templates/admin/base_site.html: {% overextends "admin/base_site.html" %} {% block extrahead %} {{block.super}} <style type="text/css"> div.cke_chrome { margin-left: 130px; } </style> <link rel="stylesheet" href="{{ STATIC_URL }}css/statfi-editor.css" /> <script src="{{ STATIC_URL }}js/statfi_csrf.js"></script> {% endblock %} since if I remove the 1st line {% overextends "admin/base_site.html" %} the borwser shows empty admin/-page. I tried to fix by adding buildins key into TEMPLATES setting: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'APP_DIRS': True, 'OPTIONS': { 'builtins': ['overextends.templatetags.overextends_tags'], } }, ] but that would require installing overextends-module. When installing it I got: django-overextends 0.4.3 requires django<2.0,>=1.8, but you have django 2.2 which is incompatible. Are there any other means to solve the problem than just downgrading both mezzanine and django version in order to get that overextends module into use ? -

How to get imagefield path in models?

I wrote a func which changing upload path for Imagefield, i'd like to get an url to that file and past it in imagekit generator for resize.

Async Request with OpenAPI Generator Python
Happy New Year EveryOne I have a particular Case in which i am using OpenAPI generator for calling the api in another Microservice. I have two microservices ie User and Customer so in Customer im am getting the information of the multiple users from User below is the example code from user.api_clients import User user_id = [1, 2, 3, 4, 5, 6, 7, 8, 9] user_list = [User.api.get(id=i) for i in user_id] and the above code will give me the user_data from User. In short it will hit user api from User 9 times one by one. So is there any way to hit this in a single shot with asyncio. I am new to this async thing in python. So ill really appreciate if anyone can give me an idea about how to do this. There is also a similar case like i want to get object from User model in oneshot for these user_id list. Yes i can use id__in=user_id but is ther anyway to hit the below code in oneshot like below code user_id = [1, 2, 3, 4, 5, 6, 7, 8, 9] user_obj = [User.objects.get(id=i) for i in user_id] Thanks for helping -
