Create A REST API with Python Flask and Flask-RestX -Project Tutorial

Flask Restx is a Flask extension that helps you build REST APIs with Flask so fast. In this video, we go into building a simple REST API that serves the book data. I walk you through how to use Flask Restx from setting up a virtual environment to implementing Swagger U to document the API.

This video is made for both beginners and advanced Python programmers who want to build REST APIs with Flask, Flask-Restx and Python.

The Swagger error at 49:21 is fixed by using

for example.

@api.expect(recipeModel)
def post(self):
pass

Thanks

Thanks a lot man. Learned a lot on the documentation. But the audio was hard to understand. Although you've already mentioned in the comments that you're sleepy.

I started to doing my project using restful, but as swagger was needed, i had to switch over to restx. What i have notice is that people in restx prefer to use api.route over api.add_resources to add a CRUD method. As i said previously, i started using api.add_resouces, therefore, my class of resources are in different files. But to use swagger, i have to import the object api over to another file. But i simplely can't do it. Could you help?

Try it something like below.. @api.doc is for query parameters, wont work for payload.
There's another thing I think instead of using request.get_json(), api.payload is used. Let me know if you have any idea about that :)

@api.expect(book_model)
@api.marshal_with(book_model)
def post(self):
''' Create a new book '''
data=request.get_json()

title=data.get('title')
author=data.get('author')

new_book=Book(title=title, author=author)

db.session.add(new_book)

db.session.commit()

return new_book #{'result' : 'Book Added'}, 201
