![]() I use render_template function from flask to show the view. By default http method is GET if you do not specify http method. I use http method GET for displaying view and POST method for sending data to server side. Next I need to validate user input data and save those input data into MySQL database, so I define another end-point /add. I then define the end-point /new_user for displaying a view where user will add new record. I first import required modules into the script. In this script I perform CRUD operations with user interaction, I display all records, I add new record, I update existing record and I delete record from the tabular data as I wish. This script is the perfect instance of Python Web Application CRUD Example using Flask and MySQL. It will also connect to MySQL database server and query the database to read, insert, update and delete. Next you need main.py script under python-flask-mysql-crud directory, that will define all URIs or Action paths for performing CRUD operations. ![]() from app import appĪpp.config = 'root'Īpp.config = 'roytuts'Īpp.config = 'localhost'Ĥ. I need to configure database connection with flask module and that’s why I have imported app module and setup the MySQL configuration with flask module. from flask import Flaskģ. I create the below db_config.py Python script under python-flask-mysql-crud to setup the MySQL database configurations for connecting to database. I have configured a secret key, which is required for your application’s session. This file should be created under python-flask-mysql-crud directory. Create the below app.py script(py is the extension to indicate Python script) where I import the flask module. This templates directory will contain all html template files, such as you need several HTML files for creating CRUD operations.Ģ. Inside this python-flask-mysql-crud directory create templates directory. Then inside this directory create python-flask-mysql-crud directory. The top level directory or project root directory, which is shown in the above figure under Preparing your workspace section. Please go through the following steps in order to implement Python web application CRUD example using Flask MySQL:ġ. In the below image you see I have opened a cmd prompt and navigated to the directory where I have to create Python script for implementing Python web application CRUD example using Flask MySQL. Let’s move on to the example… CRUD Example The image shows old version of module installation and this app was also tested recently with the latest version flask-mysql-1.5.2. The image shows old version of module installation and this app was also tested recently with the latest versions Babel-2.9.0, Flask-Babel-2.0.0, flask-table-0.5.0. Installation of Modules – Table and MySQL You may find below screen-shots how I installed the below required modules – table and mysql. If you find your any of the required modules does not exist then you need to install it. The module table is required to show data in tabular format on HTML view, the module flask works as a web framework and mysql module is required to establish connection with MySQL database and query the database using Python programming language. When you are working in the Python terminal, you need first navigate to the directory, where your file is located and then start up Python, i.e., you have to make sure that your file is located in the directory where you want to work from.įor this, Python Web Application CRUD Example using Flask and MySQL, you need modules, such as, table, flask, mysql. The first step is to check your working directory. Preparing your workspace is one of the first things that you can do to make sure that you start off well. Python web application CRUD example using Flask and MySQL.AngularJS Codeigniter REST CRUD Example.REST API CRUD Example in PHP and MongoDB.I will use Flask module to handle the requests and responses from end user or clients and this module will work as a web application framework for Python.īy default Flask module does not come with the Python installation and you have to install it separately using the command pip install flask from the cmd prompt (open in administrator mode) in Windows environment. I will use MySQL database as a permanent storage for performing such basic CRUD operations. In the below example I will create new record, read existing records, update the existing record and delete the existing record. The tutorial on Python web application CRUD example using Flask and MySQL will show you the basic CRUD operations.ĬRUD means Create, Read, Update and Delete operations.
