ModuleNotFoundError: No module named 'MySQLdb'
My code is here
from flask import Flask, render_template, request
from flask_sqlalchemy import SQLAlchemy
from datetime import datetime
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://root:#localhost/blog'
db = SQLAlchemy(app)
class Contacts(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(80), nullable=False)
email = db.Column(db.String(255), nullable=False)
phone_number = db.Column(db.String(50), nullable=False)
message = db.Column(db.String(120), nullable=False)
date_created = db.Column(db.String(50), nullable=True )
#app.route('/contact/', methods=['GET','POST'])
def contact():
if request.method == 'POST':
name = request.form.get('name')
email = request.form.get('email')
phone_number = request.form.get('phone_number')
message = request.form.get('message')
entry = Contacts(name=name, email=email, phone_number=phone_number, message=message, date_created=datetime.now())
db.session.add(entry)
db.session.commit()
return render_template('contact.html')
app.run(debug=True)
Does anyone knows, how I get this error ?

Answer 1

Running command pip install pymysql and pip install mysqldbmodel help me to kicked this freaking(**) error.
Edit:
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql+pymysql://root:#localhost/blog'
I find this solution at ImportError: No module named MySQLdb

Answer 2

datetime.now: Does not return a String you need to convert it to String or change the type in the database to date like this
date_created = db.Column(db.DateTime, nullable=True )
I have used this and it worked very will with me
from flask import Flask, render_template, request,redirect
from flask_sqlalchemy import SQLAlchemy
import sqlite3
from datetime import *
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///database1.db'
db = SQLAlchemy(app)
class Contacts(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(80), nullable=False)
email = db.Column(db.String(255), nullable=False)
phone_number = db.Column(db.String(50), nullable=False)
message = db.Column(db.String(120), nullable=False)
date_created = db.Column(db.DateTime, nullable=True )
db.create_all()
#app.route('/contact', methods=['GET','POST'])
def contact():
if request.method == 'POST':
name = request.form.get('name')
email = request.form.get('email')
phone_number = request.form.get('phone_number')
message = request.form.get('message')
entry = Contacts(name="name", email="email", phone_number="phone_number", message="message", date_created=datetime.now())
try:
db.session.add(entry)
db.session.commit()
db.session.close()
return render_template('h.html')
except:
return "Error"
app.run(debug=True)
You need to change the things i have changed like the render_template
if it did not work please provide you github
