Why @api.doc decorator python flask restplus not update the changes I make?

Question

I using Flask-Restplus to develop my API. I wanna to ask,why the @api.doc decorator not update my changes in the Swagger UI?

Here is the endpoint I define

@api.route('/create_user')
class User(Resource):
    @api.response(201, 'User successfully created.')
    @api.doc('create a new user')
    @api.expect(_user, validate=True)
    @api.marshal_list_with(_user, envelope='data')
    def post(self):
        """Creates a new User """
        data = request.json
        return create_user(data=data)


@api.route('/get_user_list')
class UserList(Resource):
    @api.doc('list_of_registered') //even I change here,in Swagger is still not update
    @api.marshal_list_with(_user, envelope='data')
    def get(self):
        """List all registered users"""
        return get_all_users()

@api.route('/create_product')
class Product(Resource):
    @api.response(201, 'Product successfully created.')
    @api.doc('12345678') //here I state to this
    @api.expect(_product, validate=True)
    def post(self):
        """Creates a new User """
        data = request.json
        return create_product(data=data)

So here is the result in my browser:

As you can see here,the doc is not updating according the string I define in @api.doc decorator.

So anyone can let me know why is this happen? And how to solve this?

Answer 1

in fact the documentation that it generates first of the comment which follows directly the declaration of your function

change that:

@api.route('/create_product')
class Product(Resource):
    @api.response(201, 'Product successfully created.')
    @api.doc('12345678') //here I state to this
    @api.expect(_product, validate=True)
    def post(self):
        """Creates a new User """
        data = request.json
        return create_product(data=data)

To that:

@api.route('/create_product')
class Product(Resource):
    @api.response(201, 'Product successfully created.')
    @api.doc('12345678') //here I state to this
    @api.expect(_product, validate=True)
    def post(self):
        """Creates a new Product """
        data = request.json
        return create_product(data=data)
