How to resend confirmation email in Django from a React front end, using allauth and rest-auth
I'm using Django 2.0.10 with rest framework, rest-auth and allauth, with a React front end. Rest-auth provides login and logout functionality using JWT token authentication, but I can't work out how to allow the user to request a resend of the verification email. I want a user to be able to log in and press a button saying "Resend confirmation email". If for example they accidentally deleted the email, they need to be able to request another. I've seen posts suggesting that you can use send_email_confirmation from allauth, but this expects a CSRF token which would be generated by a template. Here's my code: urls.py from users.views import EmailConfirmation urlpatterns = [ ... url(r'^/sendconfirmationemail/', EmailConfirmation.as_view(), name='send-email-confirmation') ] views.py from rest_framework.views import APIView class EmailConfirmation(APIView): def post(self): send_email_confirmation(user=self.request.user) When I post to the endpoint '/api/v1/rest-auth/sendconfirmationemail/', I get an error Forbidden: <p>You are seeing this message because this site requires a CSRF cookie when submitting forms. This cookie is required for security reasons, to ensure that your browser is not being hijacked by third parties.</p> <p>If you have configured your browser to disable cookies, please re-enable them, at least for this site, or for &#39;same-origin&#39; requests.</p> Any idea how I can request … -

Django Pivot Table Creation
Good Afternoon, I am working on a Django App. I have created a model like below. From that model I would like to create a view displaying such a table as below: As you can see I would like to create rows per country name in the model database and I would like to give counts per specification. I could create the table with the country names by adding a meta class to the model for the country field and then loop it with template injection. To do that I also created a view as below: def sum(request): country_list_unique = Project.objects.order_by().values('country_ordering').distinct() return render(request, 'project/project_sum.html', {'sumup':country_list_unique}) However, I don't have much of an idea how can I count the different specifications per country in views.py and how to inject them into html with Django. I would appreciate any help. Thank you very much in advance. -

Django - Is request.user cleared when leaving site?
I'm having this issue, I can't quite figure out.

I've tested numerous cases and it will always be accurate on /signup, yet when we get to /spotify/connect, request.user is now AnonymousUser. So my question is if you leave the site, as we do in step 6, is request.user cleared? -
