If we observe carefully, we have both CURD Operation can be performed in viewset
As per example in docs
...ANSWER
Answered 2021-Jun-11 at 18:02It depends on our requirements.
CRUD operations are handled in viewsets. This is the one sentance answer.
In the code you have given :
class CommentSerializer(serializers.Serializer):
since this is a normal serializer you have to write create and update method here. You can use ModelSerializer which saves you from writing definition for create and update .like this.

QUESTION
I am new to Django and API creation. I am trying to figure out if it is better to use djangorestframework
or just use JsonResponse
. I got the suggestion of djangorestframework
from Digital Ocean's tutorial but also found out about JsonResponse
, which seems simpler given that I don't have to install another package.
Goal: I would like to be able to provide user information for both web and mobile applications.
I see that there are some reasons provided on this post for djangorestframework
, which I pasted below for posteriority.
...The common cases for using DRF are:
1)You're creating a public-facing external API for third-party developers to access the data in your site, and you want to output JSON they can use in their apps rather than HTML.
2)You're doing mobile development and you want your mobile app to make GET/PUT/POST requests to a Django backend, and then have your backend output data (usually as JSON) to the mobile app. Since you don't want to pass back HTML to the mobile app, you use DRF to effectively create a REST API that your mobile app can call.
3)You're creating a web app, but you don't want to use the Django templating language. Instead you want to use the Django ORM but output everything as JSON and have your frontend created by a JavaScript MVC framework such as React, Backbone, AngularJS, etc. In those cases, you can use DRF to output JSON that the JavaScript framework can process.
ANSWER
Answered 2021-Jun-04 at 14:44DRF basically provides you many features to make APIs that you don't have in raw django.
for example:
Serializers: a declarative way(django style like declaring models) of making serializers, when you use
JsonResponse
you have to tell everywhere what to serialize, with the serializer you have to import it and just use it, also this serializers can be able to save/update objects too. Also support ORM source to connect yours models(think how difficult would be serialize a model with nested relations with JsonResponse).The Web browsable API, you can see all the availables endpoints.
Third party packages to install and use: https://www.django-rest-framework.org/community/third-party-packages/#existing-third-party-packages.

QUESTION
I am trying to deploy my Python app on Heroku, but have been unsuccessful. It seems that a problem is occurring with the PyICU
package, which I'm unsure how to correct. I've confirmed that this is the only issue with my deployment; when I remove PyICU
from my requirements file, everything works. But of course my site can't work without it.
Can anyone please guide me in how to correctly install this package on Heroku? I've tried various methods, including downloading the .whl file and then adding that to my requirements file, but then I get another error:
ERROR: PyICU-2.7.3-cp38-cp38m-win_amd64.whl is not a supported wheel on this platform.
I don't understand why - it's the correct Python and os version.
Here are the relevant excerpts from the build log:

wheel.
You can also try pyicu-binary

Let's say I have a queryset like this

Answered 2021-May-20 at 13:28The queryset
is a class variable and you are altering the value of queryset
inside the viewers_sum(...)
method.
As a result, the value of queryset
is not getting changed once the viewers_sum(...)
called, and there is the side-effect.
You can override the get_queryset(...)
method as,
