I have a issue about execute in python flask

I am new in build python api. I want to get the data depend on date.


I am following this link to code my api but I don’t know what can I do in execute.

This is my python code:

# -*- coding: utf-8 -*-
from flask import Flask, render_template, request
from flask_mysqldb import MySQL

app = Flask(__name__)
app.config["DEBUG"] = True

app.config['MYSQL_HOST'] = 'localhost'
app.config['MYSQL_USER'] = 'root'
app.config['MYSQL_PASSWORD'] = 'root'
app.config['MYSQL_DB'] = 'MyDB'
app.config['MYSQL_charset'] ='utf8'

mysql = MySQL(app)

@app.route('/',methods = ['GET','POST'])
def index():
    if request.method == "POST":
        details = request.form
        firstday = details['firstday']
        lastday = details['lastday']
        cur = mysql.connection.cursor()
        cur.execute("select * from transaction join transaction_item on transaction.id = transaction_item.transaction_id join customer on customer.id = transaction.customer_id where transaction_datetime <= lastday and transaction_datetime >= firstday VALUES (%s, %s)", (firstday, lastday))
        return 'success'
    return render_template('index.html')

if __name__ == '__main__':

This is my HTML code:

    <BODY bgcolor="cyan">
    <form method="POST" action="">
        <H1>Enter your details </H1> <br>
        first_transaction_datetime <input type = "text" name= "firstday" /> <br>
        last_transaction_datetime <input type = "text" name= "lastday" /> <br>
        <input type = "submit">

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

When you are sending requests to a back-end it does not fill out the form an easy way to do it would be to add the query values in the URL<firstName>&lastName=<lastName>

then your python code would look something like this.

@app.route('/',methods = ['GET','POST'])
def index():
    firstName = request.args.get('firstName')
    lastName = request.args.get('lastName')
    if request.method == "POST":
        # Do stuff here

Note: Use and implement solution 1 because this method fully tested our system.
