The concepts in the video help shed more light on most parts of the channels project.

Why is the video getting 30 unlike? Unlike most tutorials about channels the just repeat what's on the documentation and a serious bad job at explaining anything. The most viewed django channels tutorials was the most confusing done by just django.

This is regarding the Notifications, I have a question. for suppose i am adding credentials and submitted after doing this operation a notification has to come in to a bell icon, after we want to do changes in the page and submitted the form. i want to get the notification for the changes i made in the page. create, delete, update. How can we do this all in django.

Hi Arun . This was a brilliant video. Congrats . I have a query on the capability of Channels. Can we run a timer in the background and then take an action when that timer expires ? . The user in the front end can do whatever he likes during that time. I want to put a timer for Interview where Candidate is taking an exam while a timer is being run . He might move onto next question but clock is ticking .

Firefox: Error Failed to load the <script> with origin <script src="{% static %}" ReferenceError: channels is not defined

Thanks, that was so great. But I have still a misunderstanding. how can I send notification to just 2 consumer out of 5 consumer that was already registered and open the page for example. in the last application you teach how to filter notifications based on a specific task but I want filter it by registered user. thanks
