user_id = user_id if not user_id : raise Exception ( "user id not provided" ) def find_all_kudos ( self ): kudos = self. schema import KudoSchema class Service ( object ): def _init_ ( self, user_id, repo_client = Repository ( adapter = MongoRepository )): self. repository.mongo import MongoRepository from. The difference between the incoming request payload, represented by GitHubSchema, and the object you persist in the database, represented by KudoSchema is: The first has an user_id which determines who owns the object.Ĭopy the content below to the app/kudo/service.py file:įrom. First, you need to create a service class that knows how to translate the incoming request payload to our representation KudoSchema defined in the app/kudo/schema.py. ![]() You will soon implement the endpoints of your ReST API. In order to get that done those MongoRepository’s methods will come in handy. You might recall the user story that you’re working on is that an authenticated user should able to create, delete and list all favorited GitHub open-source projects. update ( selector, kudo ) def delete ( self, selector ): return self. create ( kudo ) def update ( self, selector, kudo ): return self. find ( selector ) def create ( self, kudo ): return self. find_all ( selector ) def find ( self, selector ): return self. client = adapter () def find_all ( self, selector ): return self. To export the environment variable, run:Ĭlass Repository ( object ): def _init_ ( self, adapter = None ): self. You might have noticed that the MongoRepository class reads a environment variable MONGO_URL. Notice that all methods explicitly use the pymongo API. deleted_countĪs you can see the MongoRepository class is straightforward, it creates a database connection on its initialization then saves it to a instance variable to be use later by the methods: find_all(), find(), create(), update(), and delete(). modified_count def delete ( self, selector ): return self. insert_one ( kudo ) def update ( self, selector, kudo ): return self. find_one ( selector ) def create ( self, kudo ): return self. find ( selector ) def find ( self, selector ): return self. kudos def find_all ( self, selector ): return self. Import os from pymongo import MongoClient COLLECTION_NAME = 'kudos' class MongoRepository ( object ): def _init_ ( self ): mongo_url = os. Check the version of Python installed by running the following command: MongoDB or the Docker toolbox installed.To complete this tutorial, there are few things you will need: Learn More About Python, Flask, and React.Add Authentication to Your React App with Okta.Python ReST API Persistence with MongoDB.Our app will be a GitHub open source bookmark project (a.k.a kudo). In this tutorial you are going to build a JavaScript application using React in the front-end and we are also going to build a ReST API written in Python which is going to persist. It facilitates the creation of complex, interactive, and stateful UIs from small and isolated pieces of code called components. ![]() React is a declarative, efficient, and flexible JavaScript library developed at Facebook for building user interfaces. You’ll also use Flask to help you to quickly put together a ReST API. The language states on its core values that software should simple, readable making developers more productive and happier. Python is a dynamic language widely adopted by companies and developers. We could also define a view component to be a droppable component, where you can drop other components, with the handleDrop function we also receive from the editor.Today’s modern web applications are often built with a server-side language serving data via an API and a front-end javascript framework that presents the data in an easy-to-use manner to the end user. ![]() Here we defined a draggable view component, which means you can drag the component and drop it elsewhere. This is great because it uses one of React's main features: composition.īuild UI ships with a special hook, called useEditor, that receives the id prop that you were passed in the component and in return, delivers a bag of useful functions that you can use for your site building logic. In our View Component, we add that extra layer of logic needed for our website builder. Enter fullscreen mode Exit fullscreen modeĪs you can see, your view component will be injected with some props: an id and some props that your Alert Component will receive (Don't worry too much about this yet, we will later see more on this).
