Mail account used by django for password reset?
I am deploying my django project. Having secured a domain name, i am now at the stage of Implementing a proper password reset mechanism on the deployed site. I need to use an email service in order to do this, and having looked around, there seem to be many options for an email provider. I could use mailgun, or gmail, or even the people who sold my domain offer a couple of email addresses along with it. I was thinking i should maybe just go with gmail, as its free and forever, and probably pretty secure, probably reliable. Can someone who knows about these matters, please advise me on what email provider i should use, or any issues i may have overlooked. I glanced at mailgun, and it seems there is a limitation on amount of emails, so maybe that is a bad idea, i dont think gmail has a limitation. If so why do people use mailgun in the first place. Surely i must be missing something. Thanks in advance. -

Django leaflet map url
Hello guys I am creating a map and I would like to set up a dynamic url so that lets say when I run 127.0.0.1:8000/20.123, 42.123 and the map to pan in that certain location. I have certain workorders for certain layers and I would like that the user doesn't pan manually to map but the map pans itself by getting the coordinates of the layer. In order to achieve this I should set a url that consists the coordinates. It would be great if I can also display a certain zoom in the url lets say 13. index.html {% extends 'workorders/base.html' %} {% block jumbotron2 %} <div class="jumbotron"> <h1>Navbar example</h1> <p class="lead">This example is a quick exercise to illustrate how the top-aligned navbar works.

Django-Filters with class-based views: Apply Django FilterSet dynamically

How JWT works with django-phonenumber-field
I have used django-phonenumber-field as my Phone number model field and serializer. It worked and everything was okay. Now, I am trying to implement Json Web Token in Django Rest Framework of these two package, djsoer and djangorestframework-jwt. I am managing and migrating an old (django 1.11) codebase to Django2. Right now, whenever I am trying to create a new auth token, I am getting an internal server error. Error message: TypeError: Object of type 'PhoneNumber' is not JSON serializable I know PhoneNumber object from Django-phonenumber-field package is responsible for this. However, The error stack is in djangorestframework-jwt. How can I add/pass PhoneNumber serializer on JWT? [ I don't get which codebase is necessary, so I have not added any. Ask me, I will describe/add later.] TIA. -
Django Custom Auth Backend is_authenticated always false
Im writing an app where a user can login with 3 different informations: customerkey, username, password. Every customerkey leads to a seperate database. so i wrote a customauthbackend for it but run into a problem i cant really solve. The Authentication works fine as long as i hardcode the customerkey into the get_user function with return User.objects.using('505473').get(pk=user_id) but when i dont do that i always get false in my templates when i call {% if user.is_authenticated %}. Is there an option to say which db he needs to call when you call {% if user.is_authenticated %}? customAuthBackend: class CustomAuthBackend(ModelBackend): def authenticate(self, request, username=None, password=None, **kwargs): user = User.objects.using(request.POST['customerkey']).get(username=username) if user is not None: return user def get_user(self, user_id): try: return User.objects.using('505473').get(pk=user_id) except User.DoesNotExist: return None -

How can I list the group names that only the authenticated user belongs to while editing a user on the Django's admin panel?
I am trying to find out to restrict the group names for an admin user on Django. There are two groups in the system; "School One" and School "Two". The picture below shows the users belonging only to the "School Two" group (including me as John Doe). For example, if I click the user "Josh Doe", I am directed to this page: What I want is to display the groups that the current authenticated user (John Doe) belongs only. That way I can assign a group (or groups) to a particular user. So, here I want to see only "School Two" option as I (John Doe) belong only to that group (added by superuser).

Django creating model instances - Validation before creation? In manager class? What is manager class for?
Say I have a class "Book" and I want to hit an API to verify the book exists before creating my model. Do I create my "BookManager" class, override create, hit the api, and throw an exception if not valid or create if valid? Then in Book I'd write objects = BookManager() And create a book with. new_book = Book.objects.create(name)? Basically, this feels like a good way to organize my code, but I'm not sure if this is intended use for the Manager class as opposed to only modifying the queryset. Additionally, does anyone have a good reference on how to structure your django rest framework app? Folder structure etc -

Chained Select/Dependent Drop-down in Django Admin
I have a model in Django, Model A. Very typical, it has various fields, some choice fields, some boolean, some character fields. I have another model, Model B, in this model, the intended functionality is that in Django Admin the first field is a select, where the user can choose from any field that exists in Model A. This is implemented already. What I need help figuring out is how to make the second field of Model B Mimic the options of Model A. If Model A has a choice field named 'Meat', and it's choices are 'Beef, Turkey, and Chicken', If the user adding an entry to Model B selects 'Meat' in field 1, field 2 will be a choice field with 'Beef, Turkey, and Chicken'. If Model A has a character field named 'Anything Goes', If the user adding an entry to Model B selects 'Anything Goes' in field 1, field 2 will be a standard text-input field. If Model A is a boolean field named 'Yes/No', If the user adding an entry to Model B selects 'Yes/No' in field 1, field 2 will be a standard boolean select field. I believe the main thing I'm looking for … -
Django Graphene - Pass info.context to a decorator on a Query or a Mutation
I am trying to pass a resolve function in a Query to a custom decorator. While **kwargs are getting passed to the decorator function, it looks like the info object is not getting passed. When I try to read the info in the decorator I get a value of None. Without the decorator, I am able to read the info object, directly in the resolve function. Please note the decorator shown below is a test code to read the info object and does not serve any other purpose. I understand there are defined decorators available in the django/graphene framework, but I'd like to understand how to pass the info object correctly to a decorator, for custom code. Thanks!

Use of Global queryset in Django REST ViewSet Views/Actions
