Django views.py: Add to favorites page

Question

I am trying to edit an html page so a logged in user can favorite a video.id

Here is the .html file

<td>
    <form method='POST' action="{% url 'foobar:favourite_post' video.id %}">
        {% csrf_token %}
        <input type='hidden' name='video' value={{ video.id }}>
        <button type='submit'>Bookmark</button>
    </form>
</td>

Here is the urls.py file

app_name = 'foobar'

urlpatterns = [
    path('', views.f_ListView.as_view(), name='overview'),
    path('<int:pk>/', views.f_DetailView.as_view(), name='detailview'),
    path('<int:fav_id>/favourite_post/', views.favourite_post, name='favourite_post'),
]

Here is the view.py file

def favourite_post(request, fav_id):
    video = get_object_or_404(Video, id=fav_id)
    if request.method == 'POST': #Then add this video to users' favourite
        video.

   return render(request, 'foobar/%s' % fav_id)

How to edit the views.py file so it is registered in the database that the user has favorited this video ?

Here is the models.py file

from django.contrib.auth.models import AbstractUser

class ProjectUser(AbstractUser):

    def __str__(self):
        return self.email

class Video(models.Model):
    name = models.CharField(max_length=255),
    videofile = models.FileField(upload_to="static/videos/"),
    favourite = models.ManyToManyField(ProjectUser, related_name="fav_videos", blank=True)

Is ProjectUser the auth user model? If not how are they related? — Daniel Roseman, Mar 28 '19 at 12:58
@DanielRoseman yes Daniel you are right and I updated the question to include that — Joseph Adam, Mar 28 '19 at 12:59

def favourite_post(request, fav_id):
video = get_object_or_404(Video, id=fav_id)
    if request.method == 'POST':
        video.favourite.add(request.user)
        # Rest code
    return render(request, 'foobar/%s' % fav_id)

Or `request.user.fav_videos.add(video)`, which is exactly equivalent but might express the intent a bit more clearly. – Daniel Roseman Mar 28 '19 at 13:04
That doesn't seem to have anything to do with this answer. You should ask a new question showing the full error traceback. – Daniel Roseman Mar 28 '19 at 13:31

It might not be so obvious, you need to first get the current logged in user by

request.user

if your view function does not require a user to be logged in so you will need to check

if request.user is not None

then add it to the list of favorites to the video

video.favorite.add(request.user)
