flask - Display database from python to html

Question

I have code like this to retrieve data from database and I want to display it in html.

This is app.py

@app.route(\'/news\')
def news():
         


        

Answer 1

Suppose you have table_name = user_info and let's visualize it:

id| name | email | phone | 1 | Eltac | eltac@gmail.com | +99421112 |

You can do something like this:

app_name.py

from flask import Flask, render_template
import mysql.connector

mydatabase = mysql.connector.connect(
    host = 'localhost(or any other host)', user = 'name_of_user',
    passwd = 'db_password', database = 'database_name')


mycursor = mydatabase.cursor()

#There you can add home page and others. It is completely depends on you

@app.route('/example.html')
def example():
   mycursor.execute('SELECT * FROM user_info')
   data = mycursor.fetchall()
   return render_template('example.html', output_data = data)

In the above code we use fetchall() method that's why ID is also included automatically

(Header html tag and others are ignored. I write only inside of body) example.html

        {% for row in output_data %} <-- Using these '{%' and '%}' we can write our python code -->
            
        {% endfor %}        <-- Because it is flask framework there would be other keywords like 'endfor'   -->
    

    

    

        
ID
        
Name
        
Email
        
Phone
    
    
    

                
{{row[0]}}
                
{{row[1]}}
                
{{row[2]}}
                
{{row[3]}}
            


--snip--

And finally you get expected result
