问题
I've installed the flask-mysqldb module with pip package management system on my Windows machine and I don't know how to run it.
I have tried to add the path to the MySQLdb in System properties and still nothing.
回答1:
When I work with Flask and MySQL in Windows, I use XAMPP that includes MariaDB, PHP, and Perl. I run the XAMPP server and start MySQL service.
I use Flask-MySQL which can be installed using pip install Flask-MySQL.
Then I create database from phpMyAdmin which comes with XAMPP. In Flask app, I declare the connection and manipulate the database.
Here is a demonstration of how to use Flask with MySQL in this Python file:
from flask import Flask
from flask import request
from flask import render_template
from flaskext.mysql import MySQL
app = Flask(__name__)
mysql = MySQL()
app.config['MYSQL_DATABASE_USER'] = 'root'
app.config['MYSQL_DATABASE_PASSWORD'] = ''
app.config['MYSQL_DATABASE_DB'] = 'matrimony'
app.config['MYSQL_DATABASE_HOST'] = 'localhost'
mysql.init_app(app)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/create_table', methods=['POST'])
def create_table():
if request.method=="POST":
try:
table_name = request.form.get('table_name')
field_name_list = request.form.getlist('fields[]')
field_list = []
for field in field_name_list:
field_list.append(field+ " VARCHAR(50) DEFAULT NULL")
field_query = " ( " + ", ".join(field_list) + " ) "
create_table_query = 'CREATE TABLE `'+table_name+'`' + field_query
conn = mysql.connect()
cursor = conn.cursor()
cursor.execute(create_table_query)
return "Table: "+table_name+" created successfully"
except Exception as e:
return str(e)
if __name__ == '__main__':
app.run(debug = True)
In this example, I created MySQL table from user input with user mentioned column names.
