Basic CRUD with Python Flask & MySQL Database

Basic CRUD: Flask & MySQL

1. Activate MySQL server:

   $ cd C:\Program Files\MySQL\MySQL Server 8.0\bin
   $ mysql.exe -u <username> -p<password>
   $ mysql -u <username> -p

   On my case:

   $ mysql.exe -u lintang -p12345
   $ mysql -u lintang -p   

2. Create a database & table on MySQL. I'll use a database called "lin_flask" & a table called "users":

   mysql>  CREATE DATABASE lin_flask;
   mysql>  USE lin_flask;
   mysql>  CREATE TABLE users (
               id int auto_increment,
               name varchar(100) not null,
               age tinyint,
               primary key (id)
           );

3. Clone this repo. Edit database.yaml file according to your database configuration, then install all the packages needed. In this project I'm using flask, flask_cors & flask_mysqldb:

   $ git clone https://github.com/LintangWisesa/CRUD_Flask_MySQL.git
   $ cd CRUD_Flask_MySQL

   Install dependencies:

   $ pip install flask flask_cors flask_mysqldb
   $ py -m pip install flask flask_cors flask_mysqldb

4. Run the server file. Make sure your MySQL server is still running. Your application server will run locally at http://localhost:5000/ :

   $ py app.py
   $ python app.py
   $ python3 app.py

5. Give a request to the server. You can use Postman app:

   See the opening screen (home.html)

   GET /

   Post a data to database:

   POST /data
   body request: {name:"x", age:"y"}

   Get all data & specific data by id:

   GET /data
   GET /data/{:id}

   Update a data by id:

   PUT /data/{:id}
   body request: {name:"x", age:"y"}

   Delete a data by id:

   DELETE /data/{:id}

6. Enjoy your code! 😎👌
