How to properly authenticate with both username and email with oauth2 toolkit
I would like to be able to login either with username or email using oauth2 toolkit - when I log with an email, I want to pass email parameter, not username to distinguish them. This is what I came up with from django.contrib.auth import get_user_model from oauth2_provider import views class TokenView(views.TokenView): def create_token_response(self, request): try: email = request.GET.copy().pop('email')[0] self.set_username_from_email(request, email) except (KeyError, get_user_model().DoesNotExist): pass return super().create_token_response(request) @staticmethod def set_username_from_email(request, email): """ Parameters used for request are for some reason stored in request.META['QUERY_STRING'] which is just url query string, we need to parse it, and replace email with username """ a = [] for pair in request.META['QUERY_STRING'].split("&"): username = get_user_model().objects.get(email=email).username items = pair.split('=') if items[0] == 'email': items[1] = username items[0] = "username" a.append('='.join(items)) request.META['QUERY_STRING'] = "&".join(a) This works, but it feels really ugly to alter the parameters like this. Is there a better way how to do it? Perhaps extend something else then TokenView? I was inspired by https://stackoverflow.com/a/44226177/4710968 but the request.POST attribute is empty and adding something to it changed nothing. I am using Django 2.1.7 and oauth2_toolkit 1.2.0 -
Paginating without model in django
this is my first post ever related to programming therefore please forgive if it is a bit silly. I'm making a website that will aggregate real estate data from some classified ads websites. I've already managed to write simple scrapers that update the website's database and now I wanted to make the actual web app using Django. The website would take data from users that can search the real estate database according to their criteria (already set up a django form and provisionary interface for that.) I'm a newbie and don't know a lot about django therefore I've been trying to use a simple function-based-view to process queries and display results based on user's choices. I've got completely stuck on pagination - as some queries might have thousands of results it's absolutely essential to implement it but django paginator seems to only be working with a predefined django model. I've tried using django paginator to no avail as it appears to require defined models. I've tried the paginate library but there is no real documentation or examples so I couldn't make it work https://pypi.org/project/paginate/ I'm thinking of writing the pagination script by myself but it will take me a very … -

How to add section titles/headers in between form fields in django?

Is there any way I can relate multiple users(different type) from my custom user model to my other models?
I am trying to make to take advantage of django's authentication system, but having difficult time with user models I tried to extend my user model using these tutorial: https://simpleisbetterthancomplex.com/tutorial/2018/01/18/how-to-implement-multiple-user-types-with-django.html. It was easy to follow and understandable until I got stuck while relating my newly extended user model to my existing models. My model has fields that relate to two types of my users at the same time, and I am using tuple within the field to differentiate my users. I searched for answers but the solutions are generic and I keep getting clash error messages when I tried to migrate. class User(AbstractUser): USER_TYPE_CHOICES = ( (1, 'Registral'), (2, 'Teacher'), (3, 'Parent'), (4, 'Admin'),) user_type = models.PositiveSmallIntegerField(choices=USER_TYPE_CHOICES) telephone = models.CharField(max_length = 50, null=True) is_active = models.BooleanField(default=False) class Registral(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE,primary_key=True) Admin_created=models.ForeignKey(get_user_model(), on_delete=models.CASCADE) class Parent(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) parent_of = models.ForeignKey('Student',on_delete=models.CASCADE) class Student(models.Model): first_name = models.CharField(max_length = 50, null=True) last_name = models.CharField(max_length = 50, null=True) grade = models.IntegerField() member_of = models.ForeignKey('communicate.Class', on_delete=models.CASCADE) contact_parent = models.ForeignKey('Parent', on_delete=models.CASCADE) registered_by = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) How to migrate without error -
LDAP connect failed: socket connection error while opening: [Errno 111]
I recently deployed my Django project on a Linux Ubuntu server using LDAP backend for user authentication. Everything was working fine, but now I am receiving the error: LDAP connect failed: socket connection error while opening: [Errno 111] Connection refused when I attempt to login. The only real change I have made since the last working version was that I switched to using Google DNS (8.8.8.8). Would this cause any issues? Additionally, the LDAP backend works fine on the localhost. -
Multiple nested inheritance in templates

Model translation in Django Rest Framework
I'm developing an API with Django Rest Framework, and I'd need some models with a few fields that should support translation in multiple languages then, of course, serializers should have to retrieve the field with the expected language. I've thought about two options: adding extra fields to the model (one field for language) or creating another model with all texts in every language. On the other hand, I've seen that there are some libraries such as django-modeltranslation that are intended to solve that issue, however, I'd like to know some opinions about them. What do you think? What would you recommend to me? Thank you very much -

Parallel stored procedure execution in MySQL
I have a web application with following setup: Django 2.1.7 web application. I'm using gunicorn as my web server. Script to startup gunicorn server: gunicorn project_config.wsgi:application --worker-class=gevent --worker-connections=1000 --workers=8 I have concurrent API requests (It does some heavy processing, but mostly it is stored procedure calls - most time spent in doing IO). So when serving multiple API calls, I'm running multiple stored procedure calls parallely. Since I'm starting up my gunicorn server using gevent worker class, it creates 8 worker processes (not green-threads). Which means there is no context switching happening between each API requests. But my stored procedure call execution time doubles with number of API calls. So essentially a API request which gets completed is 10 minutes takes 20 minutes if there is another API call getting served parallely. Similarly if there are 3 requests being served parallely, each request is taking 30mins. Initially I thought this is something to do with multi-threading and GIL lock, as python threads do not actually run parallely. But when I print the PID (using os.getpid()), each requests prints unique PID (pid of the gevent worker process). My stored procedure is a complex select statement. It does not perform any DELETE/UPDATE … -
Django: Reference to an outer query may only be used in a subquery

Django - What is the most pythonic way to update my page via AJAX?
I want someone with "manager" access to be able to view all user activity, and the page should continuously update after every couple of minutes via AJAX. Should I have both users and AJAX requests get sent to the same URL? Or should I have two separate URLs (one that renders a template and another one that only returns JSON)? Here is how I imagine this should be structured: def index(request): context = get_user_activity() if request.is_ajax(): # Process the data and only return updates they don't already have on their screen return JsonResponse(updated_data, status = 200) return render(request, 'activity.html', context) domain.com/activity/ <-- Users and AJAX requests are sent to this url OR domain.com/activity/ <-- Users get sent to this page domain.com/api/update-activity <-- AJAX requests are made to this URL -

Django error admin.E033: username is not an attribute of users.CustomUser. Why is my custom user admin not working?
I am creating a custom user model in Django. I have defined a custom user model (users.CustomUser) which subclasses AbstractBaseUser.
