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

Here is the .html file

<td>
 <form method='POST' action="% url 'researcher_view_app: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

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':
 video.

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

• First you modify the models.py that has the user models

class ProjectUser(AbstractUser):
 images = models.ManyToManyField(Images)

 def __str__(self):
 return self.email

• In the .html file add the following:

% for image in available_images %
/* show image */
<form method='post' action="% url 'user-image-add' %">
 % csrf_token %
 <input type='hidden' name='image' value=image.id>
 <button type='submit'>bookmark</button>
</form>
% endfor %

• In your views.py add the following method

def user_image_add(request):
 user_image_form = ImageForm(request.POST or None)
 if request.method == 'POST' and user_image_form.is_valid(): 
 request.user.images.add(user_image_form.cleaned_data['image'])
 return JsonResponse(status=200)
 raise Http404()

• Create a forms.py file in your add and add the following:

class ImageForm(forms.Form):
 image = forms.ModelChoiceField(queryset=Images.objects.all())

To show those bookmarked images you can just iterate over request.user.images (it gives you a QS of Images) similar to code above.

• In the urls.py add the following:

path('user-image-add/', views.user_image_add, 'user-image-add')

• In models.py add a method in User model for getting bool if video is bookmarked

def is_bookmarked(self, video_id): 
 return self.bookmarked_videos.filter(id=video_id).exists()

simirlarly is_bookmarked can be added to Video model accepting user_id and checking video.projectuser_set.

And add the following to your .html file where users bookmarked a video

`% if video.is_bookmarked %`

• Delete the UserProfile as you do not need it. Just make sure to have needed instance in context of view.
