django-allauth; how to just redirect to a page if the user's email is invalid
I'm trying to limit the email to a specific domain. My custom adapter is like this class CustomSocialAccountAdapter(DefaultSocialAccountAdapter): def pre_social_login(self, request, sociallogin): user = sociallogin.user if not user.email.split('@')[1] == "example.com": what I want to do is just to redirect to home page without allowing the user to log in. But seems like when I use redirect method, the user who has invalid domain is also logged in. Anyone who can give me tips? -

How to get someone up to speed in Django template language with no programming background
I've been struggling with this issue for a while and after some searches, I've decided to ask here for help or any tips or advices. I am creating a Website (in future, Web API using ReST for Mobile apps) with Django and I have someone who has been doing UI and Graphics for a couple of websites, android apps and games, etc. The guy does not know any programming language, and his background is Graphics/3D modeling, but knows HTML/CSS and a bit of JS. Using Dreamweaver and Maya, he can create good-looking websites and useful UI without writing a single line of code. I tried to show him how Django Template language works but he gets confused here and there. I tried looking for resources on how Django template system works or some useful tutorials for its front-end, but the problem is, the documentation on Django website is for version 1.7 and we are using Django 2.1 and it needs some understanding of Python and Django. Also, I want to give him something solid to learn and work with, so in the future he can handle web front-end templates in Django easily. Are there any resources (Website, documentation, tutorial, etc.) β¦ -

Django Rest Framework what is the meaning of arguments being passed to the ModelSerializer?
I am trying to understand the arguments which are being passed into the serializers.ListUserSerializer(). I understand that last_five is the data to be returned through the serializer. Where I fail to understand is where this model has a to-many relationship. From reading the DRF documentation, many=True is passed when the model has a to-many relationship. However, I do not understand how this is specifying the to-many relationship. I see a couple of possibilities . . . one to many between current user and all other users one to many between current user and last_five Users query Also I am not quite understanding the context argument. I think that it is simply the request call to the api being included in the payload to the client. The code base for this is here class ExploreUsers(APIView): def get(self, request, format=None): # the "-date_joined" specifies descending order vs "date_joined" last_five = models.User.objects.all().order_by('-date_joined')[:5] # many=True provides to-many relationship from one user to many users serializer = serializers.ListUserSerializer( last_five, many=True, context={"request": request}) return Response(data=serializer.data, status=status.HTTP_200_OK) -

requesting a url from clients ip
Is there any way that without rendering template I make a request from python module and that request is made from client ip When ajax calls are made in django templates the requests hit are hit by clients ip but when I make request via method below import requests x = requests.get("http://ip-api.com/json/") When I get the response from x it always gives the ip on which django website is hosted. for e.g if my website is hosted on 139.12.3.245 when i print ip it always gives (139.12.3.245) but I want to hit the api from clients side as we are able to do in ajax I want to hit an api from clients ip without rendering a template.How can I do that?or is it not possible? -

Django; canot load static files

Using a Custom User the Password Validation from settings are ignored on registration
In Django I created a custom User. My issues is that the default validators are not working, any password is accepted.

Django Serializer - Decide which fields are serialized at runtime
I am using DRF and have a model which is serialized. There are times when I want to include all the fields in the data that is sent to the api end point, and times when I want just a sub-set of the properties (for instance list view vs edit view). Is it possible to declare all the fields in one serializer, and then specify only a subset when calling the serializer. Here is an example of what I would like to do: queryset = Foo.objects.filter(active=True) FooSerializer(queryset, many=True, fields=["id", "title"]) I could then use this output to populate a the options of an HTML select element. Meanwhile FooSerializer looks like this: class FooSerializer(serializers.ModelSerializer): id = serializers.ReadOnlyField() class Meta: model = ProgressNoteCustomType fields = ( 'id', 'title', 'modified', 'active', 'user' ) read_only_fields = ['id'] While I could write another serializer, that just has the id and title field in the Meta definition, it's not DRY. Then I have another scenario where I want to display a list view where the user can click on an item and edit it - here I want to display just title, modified, and active. Writing something like FooSerializer(queryset, many=True, fields=["id", "title", "active"]) seems like the β¦ -
