Example

users = [{'name': 'Michael'}, {'name': 'Ivan'}]


class UserPostSchema(Model):
    name = StringType(required=True)


@resource('/users')
class Users:
    async def get(self, request):
        return users

    @validate(user_data=UserPostSchema)

        users.append({'name': user_data.name})
        return '', 204

Guide

• resource(uri='') - return decorator for classes that will be considered RESTful resources. This decorator automatically extends HTTPMethodView (refer to sanic documentation for details). You can provide resource URI through decorator or by class attribute uri. You can provide decorators for all the methods through class attribute decorators.

  Examples of possible return values for handlers:

  return "data", 200, {"X-Custom-Header": "Value"}
  return "data", 200
  return "data"
  return {"arg": "val"}
  return ["val1", "val2"]
  return "", 201
  
  return sanic.response.json # .text, .html, e.t.c.
  

• Api(name='API', url_prefix) - class for aggregating resources and registrating them in the sanic application. Internally it uses blueprints. Basic workflow:

  from sanic import Sanic
  from resources import User, Users
  
  app = Sanic()
  
  api = Api(url_prefix='/api/v1')
  api.add_resource(User)
  api.add_resource(Users)
  api.init_app(app)
  
  # ...
  

• validate(**models) - decorator for methods, that will validate incoming data with provided models from Schematics library. Successfully validated and parsed models will be passed as keyword arguments to the handler method. If any model fails to validate - handler will not be called.

• error(description=None, details=None, status=400, **kwargs - method for returning errors from handlers.

• collect_args(request) - method for getting data from all possible sources of data in the request.
