Django Allauth - Cannot retrieve profile picture from Facebook
I am trying to build a website and integrate it with Facebook to authenticate. I'm also trying to get the profile picture and show it in the website. As Django Authentication I'm using django-allauth. I managed to login in and authenticate with Facebook, however I seems to have an issue when trying to get the profile picture. I'm using this html code in my template: <img class="rounded-circle account-img center-align" src="{{ user.socialaccount_set.all.0.get_avatar_url }}" width="80" height="80"> Am I'm getting this picture. Any help please on what I'm doing wrong or maybe there is an alternative to get the profile picture of a user? Thanks -

One view for two models with redirect
I have Django app with the following model: class Author(models.Model): name = models.CharField(max_length=200) slug = models.SlugField(max_length=200, unique=True) This is now using simple generic view: class AuthorDetail(DetailView): model = Author def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) # some additional context thingies return context and with the following URL configuration: path('author/<slug:slug>/', AuthorDetail.as_view(), name='author-detail'), Now I want to introduce simple aliases for authors, so for example instead of /author/william-shakespeare I can reach the page also as /author/ws or /author/my-favourite-author. I came up with this idea (I know that destination could be key to Author, but that (I think) would not change much in the case): class AuthorAlias(models.Model): slug = models.SlugField(max_length=200, unique=True) destination = models.CharField(max_length=200) So to achieve the redirect I came up with the following in the view: def get(self, request, **kwargs): slug = kwargs['slug'] try: self.object = self.get_object() except Http404: self.object = get_object_or_404(AuthorAlias, slug=slug) return redirect(reverse('author-detail', args=[self.object.destination])) context = self.get_context_data(object=self.object) return self.render_to_response(context) Everything seems to be working fine, but I was wondering it there is a better approach and if this approach can cause any issues I'm not seeing? -

Multiple Choice with django
Im working on a quiz application with Django. Im struggling with making a form that can act as the multiple choice. I have to pull the questions and answers from the database so, i then display them on the page. I was going to just put booleanfield checkboxes beside the displayed choices, is there a better way to do this? I recently became aware of the multiple choice field, but i believe it aids in displaying the choice as well. I just want there to be 'boxes' i can customize with css. Is there anyway to have the field pull from the database or can i use the multiple choice field to display the wanted boxes by the answer choices already displayed.
