Blog API with Django Rest Framework 14 of 33 - Hyperlinked Identity Field for URL

** Blog API with Django Rest Framework ** is a project to build a RESTful API service for the blog we created in Advancing the Blog and Try Django 1.9.

RESTful API services allow our applications to connect with other applications using JSON-formatted data. An strong API can enhance our applications ability to provide value to other services and end users. This type of API is very common in modern web application development.

Generally the topics will include:
- Django Project Setup
- Class Based Views (& some Function Based Views)
- Models, Model Forms, Forms, Form Validation
- Integrate Bootstrap front-end framework.
- Django Registration Redux for Authentication/Registration
- And More

Just in case if someone comes back for reference here, if you are getting error as "Could not resolve URL for hyperlinked relationship using view name "posts-api:detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.
"
and you are using django 2+ then change your url from

path('posts/<slug:slug>/', PostDetailAPIView.as_view(), name='post_detail') to
path('posts/<slug>/', PostDetailAPIView.as_view(), name='post_detail')

and it will work, realized it after spending 2 hour on it 🤷

Adding url using hyperlinkedidentityfield requires lookup properly in view class and serializer class look_up field should be same and and if you do not have that field(look_up) use pk otherwise it will show you error. Model(Tweet) has no obj (tweet_id).
And dont pass name of include url as well as app_specific url, say if you have

in project file
path('api/tweet/', include('tweet.urls'), name='tweet'),
in app.urls file
path('api/tweet/<int:pk>/', TweetDetailView.as_view(), name='detail'),
then in view_name of HyperlinkedIdentityField pass
url = serializers.HyperlinkedIdentityField(view_name='detail', lookup_field='pk')

"Could not resolve URL for hyperlinked relationship using view name "posts-api:detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.
"

removed the posts-api:

view_name='delete',
view_name='detail',

this worked for me

my project is using python 3.8.10 ... django 4.0 .. drf 3.13.1

What is the use of that lookup_field? And you included slug in that field. can we use any other field of model?

i have a error if a click to the next page it says:
Could not resolve URL for hyperlinked relationship using view name "post-api:postdetail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.
