Create Login View using Django simpleJWT
I'm trying to implement a login API using JWT Authentication. I used the simpleJWT in Django. my setting.py 'DEFAULT_PERMISSION_CLASSES': ('rest_framework.permissions.IsAuthenticated',), 'DEFAULT_AUTHENTICATION_CLASSES': ('rest_framework_simplejwt.authentication.JWTAuthentication',) SIMPLE_JWT = { 'ACCESS_TOKEN_LIFETIME': timedelta(minutes=5),} } my urls.py urlpatterns = [ path('admin/', admin.site.urls), path('', include('apartments.urls')), path('api-auth/', include('rest_framework.urls')), path('api/token/', TokenObtainPairView.as_view()), path('api/token/refresh/', TokenRefreshView.as_view()) ] I want to use the default user model for the login.Also the login must be done only if the user is authenticated. And I need get a POST request and to return the users credentials and the two tokens in my response body. How can I adjust my loginview accordingly? def login_view(APIrequest): if request.method == "POST": username = request.POST["username"] password = request.POST["password"] user = User.objects.get(username=username) if user.check_password(password): username = user.username user = authenticate(username=username, password=password) print("Login successful") login(request, user) ``` -

Django admin calling the ```.save()``` method when trying to log in to the admin site
The auth user model extends AbstractUser and overrides the .save() method. The model contains two mandatory and unique fields. It also calls .full_clean() in the .save() method. The problem arises when an admin tries to log in. Django throws a validation error saying those two fields can't be blank. The error goes away when .full_clean() is commented out. Why does Django admin call the .save() method while trying to log in to the admin site? -

Django REST app returns 502 Bad Gateway on HTTP requests containing data once hosted on GAE
I created simple Django REST app and allowed all of the hosts for CORS in my settings.py using: ALLOWED_HOSTS = ['*'] CORS_ALLOW_CREDENTIALS = True CORS_ORIGIN_ALLOW_ALL=True I use Postman for faking requests from client-side and one of the request I am attempting is rest-auth/registration/ request. When do a registration for locally hosted Django REST app all works fine and it responses with 200 but once I deploy it to GAE the following thing happens: If I send the empty request (that is without username, password, password_confirmation) I receive normal response that the fields are mandatory, but once I add those strings to my request the response takes long time and the outcome is 502 Bad Gateway and in my GAE logs I can only see "POST /rest-auth/registration/ HTTP/1.1" 502 [CRITICAL] WORKER TIMEOUT (pid:17) What can be the issue here? What am I doing wrong? -

Pass python list from context to JS function
I have a view that renders a dictionary of data for each country like below: def InvoicingDashboardView(request): # For reference - "c" is the context dictionary, and it's already initialized by this point for client in Client.objects.all(): fte = frame.fte(c['start_date'], c['end_date'], time = 'external', client = client.id) if fte > 0: c['countrys'][client] = { 'name': client.name, 'fte': fte, 'var_fte': fte - frame.fte(c['var_start_date'], c['var_end_date'], client = client.id), 'daily_ftes': [frame.fte(day, day) for day in c['label_days']], } return render(request, 'dashboards/invoicing.html', context = c) As you can see, for example, if i call {{countrys.client.fte}} i'll get the fte for that client. Everything good till now, but i'll need the daily_ftes for a JS function, like below: <div class="dash_countrys_ftes"> {% for country, items in countrys.items %} <div class="dash_country_block"> {% with name=items.name fte=items.fte variation=items.var_fte flag=country.flag.url %} {% include 'dashboards/charts/country_block.html' %} {% endwith %} </div> <script> countryFteVariation("{{items.daily_ftes|escapejs}}") // HERE </script> {% endfor %} </div> The problem is that daily_ftes is a python list. What can i do here in order to javascript read it as list instead of a string? -
