A Comprehensive Tutorial to Swagger

Procedures:

We will be initially installing multiple libraries

In the terminal of the IDE you are using, write the following commands one by one
pip install pyyaml

pip install uritemplate

Go to urls.py in the API folder

add the following line

from rest_framework.schemas import get_schema_view

Add the following line in urlpatterns

path('api_schema',get_schema_view(title = 'API Schema', description = 'API documentation'), name = 'api_schema'),

Check the documentation after running the server

Use the link http://127.0.0.1:8000/api/api_schema

Install Swagger using the command

pip install django-rest-swagger

Go to the settings.py file

In the TEMPLATES list, insert the following line into DIR os.path.join(BASE_DIR, 'templates')

Under the API directory, create a new folder. Call it templates

In the templates folder, create the file docs.html

Copy the code in the link "Check the third step."

Back to the URL.py, add the following lines in urlpatterns

from django.views.generic import TemplateView
path('docs/', TemplateView.as_view( template_name='docs.html', extra_context={'schema_url':'api_schema'}), name='swagger-ui'),

Check the documentation after running the server

Use the link http://127.0.0.1:8000/api/docs/
