'Access-Control-Allow-Origin' in Django app with Django-cors-headers
So I am getting the following error in one of my web pages. XMLHttpRequest cannot load http://coolkites.com/static/modelling/models/parented.json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.coolkites.com' is therefore not allowed access. After researching this issue I came across Django-cors-Headers. After pip installing it. I added the following to Middleware and also set CORS_ORIGIN_ALLOW_ALL to True MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', #'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] # CORS Config CORS_ORIGIN_ALLOW_ALL = True CORS_ALLOW_CREDENTIALS = True However I am still getting this issue. Any suggestions ? -

django rest framework api and angular 2 integration
I'm developing back-end API with Django Rest Framework and front-end with Angular 2. The django server runs on localhost:8000 and the angular server runs on localhost:3000. When I try to access API using angular 2, it gives me the following error: customerregister:1 XMLHttpRequest cannot load http://127.0.0.1:8000/user/signup. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. What I want to ask is how to integrate the development of Django Rest API and angular 2 project. -

Creating a Table of Old Passwords in Django 1.9
What I am trying to do: Create a database table of 2 most recently used passwords (not including current). What have I discovered so far? I have discovered the check_password('123') function To my knowledge, this compares newly entered password to the current password before running User.set_password() I have created a table to store a username with the two previously used (not including current) passwords. I have discovered two different hash numbers User.get_session_hash() Not sure if this is used for the password hashing? User.set_password.hash() Again, not sure if this is used for the password hashing? My Issue: In my python shell (under my project), I use User.set_password() and set the same current password after running User.password. Then when I run User.password again and see that there is a different hash. How do I save the previous password hashing method and re-use it to re-hash the password in order to compare it to the previously hashed password?? My research amongst this sight brought me to this post: How to implement password change form in django 1.9 -
Django Queryset Annotate function Rails equivalent
So I'm rewriting my app from Django to Rails, & I'm current stuck on this piece of code conversations = Message.objects.filter( user=user).values('conversation').annotate( last=Max('date')).order_by('-last') users = [] for conversation in conversations: users.append({ 'user': User.objects.get(pk=conversation['conversation']), 'last': conversation['last'], 'unread': Message.objects.filter(user=user, conversation__pk=conversation[ 'conversation'], is_read=False).count(), }) How would I rewrite this in Rails? More specifically, the values('conversation').annotate() part. I've tried this, but still nothing: conversations = Message.where(user: user).select(:conversation, :created_at).distinct(false).order(created_at: :desc) Thank you. -

Django DRF - ListCreateAPIView POST Failing with depth=2
I have a ListCreateAPIViewfor showing a list of contacts, as well as for creating new contacts which uses this serializer: class ContactPostSerializer(serializers.ModelSerializer): class Meta: model = Contact exclude = ('id',) For POSTing new records, I have to specifically exclude id so that DRF doesn't complain about a null id. But, for listing records with this serializer, the serializer doesn't return the objects in ForeignKey fields. To get these objects, I add depth = 2. So now the serializer looks like this: class ContactPostSerializer(serializers.ModelSerializer): class Meta: model = Contact exclude = ('id',) depth = 2 However, now, with depth = 2, I can't do POSTs anymore. It complains again of null id values. Edit: I should add that the errors that come up with I have depth=2 are specific to the models of the Foreign Key objects, not the new record I'm creating. What am I missing here? -

Django REST Framework: require login to view API
I am working through this series on the Django REST Framework and have a few videos left: https://www.youtube.com/playlist?list=PLEsfXFp6DpzTOcOVdZF-th7BS_GYGguAS Unless I missed it somehow, I haven't seen anything on how to require login to view the API. I Googled such things as "Django REST require login", but didn't see anything other than creating authorization in general using Django REST API. I imagine there is a way to do it and would like to implement it because having a wide open API wouldn't work for my project. Can someone point me in the right direction for setting login required for the API? -

Django rest framework and iOS authentication using id token from Google
I was wondering if there are any packages out there that I can use to authenticate a user based on the id token that a user receives from Google Auth on iOS. Here is the link to Google's documentation on id token based authentication. I've read about it and searched for a simple package to use for handling the authentication but I could not find one that accepts the id token. So far I have tried and implemented django-rest-auth but it requires either an access token or code both of which do not work if I pass in the id token. I believe django-rest-auth is useful if server-side access is required, which is not my case. I appreciate any help, thanks! -
Python stops working on manage.py runserver

Windows will close the program and notify you if a solution is available.

Django Ajax Return Multiple json Objects
I have a simple Ajax method: $.ajax({ type:'GET', url: '/getNotifications', success: function (data) { console.log(data); $('#event_invites li').empty(); $('#team_invites li').empty(); $.each(data, function(key, value){ var type = value.model; if(type == "prof.teaminvite"){ $('#team_invites').append("<li>" + value.fields.Invitee + "</li>"); } else if (type == "fullcalendar.eventinvite"){ $('#event_invites').append("<li>" + value.fields.Invitee + "</li>"); } }); } }); My getNotifications: def getNotifications(request): notifications = [] team_invites = serializers.serialize('json',TeamInvite.objects.filter(Invitee=request.user.id)) team_data = json.loads(team_invites) json_team_data = json.dumps(team_data) event_invites = serializers.serialize('json',EventInvite.objects.filter(Invitee_id=request.user.id)) event_data = json.loads(event_invites) json_event_data = json.dumps(event_data) notifications={ 'team_invite':json_team_data, 'event_invite': json_event_data } print(notifications) return HttpResponse(json_team_data, content_type='json') # Multiple objects, single model As you can see I want to return multiple objects from multiple models. I am able to return multiple objects from a single model so far from the above code. I return the TeamInvite objects using json but I also want to pass in the EventInvite objects as well. As you can see, I have tried creating a dict and storing the json objects with the appropriate keys. The data gets passed through, however, I don't know how to retrieve the data in the ajax function. I want something like this: data['team_invite'].model // Gets model type data[team_invite].field.Invitee // Gets the invitee data[event_invite].field.id // Gets event id Is this possible? Thanks -

But in that method I would like to access ballot address and choice options like Voter text and voter address for each voter. Is it possible to access the user entered data on the save_model method?
