I struggled a lot to learn this for days. Thank You! It's very clear now.

[@ajaysharma1560]

Please keep posting .. Your work is really very helpful.

[@litebook1951]

Where from did you learn class based view?

[@liorbm1]

Is this in Django REST Framework ? Or in Django ?

[@mujeebishaque]

Got your email recently about the new flask uploads. I haven't checked it out as I am more into Django. This video is pretty easy to follow and understand. Thanks Anthony.

Class based views are most probably awesome, but in this particular case it just doubles the amount of lines. I cant find any added value except turning it slowly into Java. I dont know a thing about class based views, it's just my first impression. I was sure improvements works other way around - reducing boilerplate instead of literally multiplying it.

[@MK-oj8ol]

This video misses most of the point of class based views. The author is using the most basic 'view' object, which requires that he repeat most of the logic from his function based view in the class based view, which provides very little benefit. The true 'magic' happens when your new class based view inherits from one of the generic views such as FormView, CreateView, UpdateView, etc. All you have to do is set a few properties within the class and eliminate the boilerplate code that is shown in this example. If you are watching this video you should really try to find another example that illustrates use of the generic views in order to better understand the true power of class based views.

in CarView class there are two functions called get and post. Those name are default by django or can i give a different name for those tow classes

Hi Team, I am using CLass based views (ListView) and want to display the list of items but at the same time need to join two tables to get the desired result. Any info where i can overwirte the method or function to use custom based query.? Looking for response... Thanks

Maybe this will help you: docs.djangoproject.com/en/2.2/topics/class-based-views/generic-display/#dynamic-filtering

[@jonathanhirschbaum6754]

Seriously? You just type random video in YT loosely similar to your job and simply ask author to solve your completely unrelated problems? While on it, Im looking for Mexican recipes, preferably beans and chili, can someone paste it here?

[@felomleron.ml101]

@@jonathanhirschbaum6754 do you still need recipes?

[@alfredglaygbo6595]

I'm finding it difficult to understand the use of class base view

[@sushant6295]

great videos dude.... why did you use pk=2 . can anyone clarify

[@prettyprinted]

As an example. Since I wasn't taking user input, I needed a way to change the data.

[@zhaoyinqin1813]

I saw people using form_class, add_form, and form. What are the differences?

[@krystianpominski5162]

It's just local variable. You can even name it "something" and the only difference is gonna be that how you named it.

[@marvinotieno2194]

How can i pass a primary key of an object to a class based view?

[@prettyprinted]

You can set up the url to accept IDs like with function based views. Then in the method inside of the class, you add the ID to the parameters after request.

[@marvinotieno2194]

[@zulfiqarabid2755]

I've a REQUEST... can you make a video on more real projects like. a small website where we login as admin and have authority to remove or add other accounts. and someone can easily make an account and start posting etc. like a mini social network? wouldn't be that great?

[@prettyprinted]

I do want to make more complicated examples that aren't in my courses. Look out for those videos.

[@webtutor1002]

in class multiple methods is there how i can pass this method in url file in is_view()

[@prettyprinted]

I'm not sure what you mean.

[@webtutor1002]

​@@prettyprinted if i created user defined method inside class how i call him in url

[@rohitbhanot7809]

Though I always like all of ur videos, but in this case, I don't really get when n why would u use class based views

[@prettyprinted]

It's just a different way of organizing the code. Class based views would be useful if you either plan to have endpoints with the same name but multiple request methods. Or if you want to use the Django generic class methods to save writing repetitive code.

[@Shadownrun2]

come on... you could make a def for rendering instead of declaring form, context and calling render for both methods! That is super usefull!! anyways thank you for the video

[@prettyprinted]

You're welcome! Thanks for watching!

[@JG-qj1xb]

This is a pretty bad way to use the class Model in django.

[@mujeebishaque]

please teach a good way then.
