![]() For example, the following Python program creates a new database file pythonsqlite.db in the c:\sqlite\db folder. ![]() Return render_template( "result. To create a database, first, you have to create a Connection object that represents the database using the connect () function of the sqlite3 module. 1įrom flask import Flask, render_template, request The following is the complete code for the Flask-SQLite application. import sqlite3 Create a SQL connection to our SQLite database con nnect (dbfile) cur con.cursor () The result of a 'cursor.execute' can be iterated over by row for row in cur.execute ('SELECT FROM '): print (row) Be sure to close the connection con. Return render_template( "list.html",rows = rows)įinally, the ‘/‘ URL rule renders ‘home.html’, which is the entry point of the application. The application contains another list () function represented by the ‘/list’ URL.It populates’rows’ as a Multidict object that contains all records in the student table.This object is passed to the list.html template. The HTML script for result.html contains an escape statement, which displays the result of the Insert operation. Return render_template( "result.html",msg = msg) = )Ĭur.execute( "INSERT INTO students (name,addr,city,pin) The addrec () function retrieves the form’s data through the POST method and inserts the student table.The message corresponding to the success or error in the insert operation will be rendered as ‘result.html’. new_student ():Īs can be seen, the form data is published to the ‘/addrec’ URL of the binding addrec () function. The first new_student() function is bound to a URL rule ( '/enternew').It presents an HTML file that contains a student information form. In this guide, well see how to connect to a database, create. Our Flask application has three View functions. Instead, we only need to import the built-in Python library sqlite3 to use this database. 1Ĭonn.execute( 'CREATE TABLE students (name TEXT, addr TEXT, city TEXT, pin TEXT)') The program creates a SQLite database ‘database.db ‘ where the student tables are created. To create a database, first, you have to create a Connection object that represents the database using the connect() function of the sqlite3 module. You can create an SQLite database from Python code. The SQLite database storse all data in a single file. ![]() Related course: Python Flask: Create Web Apps with Flask Create database and table Each database can have tables and each table can have records. SQLite is a relational database system that uses the SQL query language to interact with the database. ![]() W the Flask application interacts with SQLite.
