The file swagger.py offers access to a Swagger user interface, which is used to For example, blueprint_x.py may containĪll API functions associated with functionality x. blueprints: Blueprints are a way to structure a collection of API endpoints.Here, all other modules are loaded and the application is defined. app.py: This is the main file of your application.This is the entry point to your application, which must be configured via app.ini. wsgi.py: WSGI stands for web service gateway interface.Most importantly, it configures how your application should be served through app.ini: This ini-file configures your application.requirements.txt: Tracks the dependencies of your application such that they can be installed via python -m pip install -r requirements.txt.The file structure for a minimal Flask application that offers only a REST API should look something like this: flask_app/ How to Structure a RESTful Flask Application In this post, I want to show you what I find to be helpful patterns for the development of RESTful Flask applications. How to document your API, and how to test the functionality. While Flask is surprisingly easy to work with, it takes some time to learn about best practices, such as how to structure your code, Therefore, you should particularly choose Flask over Django if you want to be flexible about the libraries you utilize or want to build a lightweight application. In contrast to Django, Flask follows a minimal approach. To check routes you can print the app.Flask is a lightweight Python web development framework that is becoming more and more popular, as you can see from this comparison You can set the url_prefix on register blueprint (it has priority) or when you create it. If you would import the api from main application _init_ then you can't register each blueprint with it's own params like url_prefix. You dont even need to add a "main" application blueprint. Then in main application _init_.py just import modules blueprints and register it. In routes import foo_api and add resources to itįoo/routes.py from flask_restful import Resourceįoo_api.add_resource(TodoItem, '/todos/') Create new Api instance in each module and pass to it a blueprint.įoo/_init_.py from flask import Blueprintįoo_bp = Blueprint('foo', _name_, url_prefix='/foo') and register their blueprints with url_prefix to not repeat the common part in each added resource. If you want to have submodules (like your /api) based on resources. blogs import main as blogs_blueprintĪlso note, you don't need to register api.init_app(app) anymore. users import main as users_blueprintįrom. Lastly, make sure to register the flask-restful api blueprint within your create_app function: app.register_blueprint(api_bp) from flask import Flask, Blueprintįrom. The key points here are to create a Flask Blueprint instance & pass it to a new instance of flask-restfuls's Api class. I keep getting the following error messageĪttributeError: 'Blueprint' object has no attribute 'add_resource'Īpp.om_object(config)Īpi/_init_.py from flask import BlueprintĪpi/routes.py from flask_restful import Resource I am trying to use Flask restful as a Blueprint in a pattern that works for other blueprints.
