How to bookmark a page in Django? - django

Question

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)

Answer 1

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.
