pip install Flask Flask-MySQLdb
Install dulu modul TextBlob:
pip install textblob
2. Buat Database MySQL
CREATE DATABASE sentiment_db;
USE sentiment_db;
CREATE TABLE sentiment_log (
id INT AUTO_INCREMENT PRIMARY KEY,
text TEXT NOT NULL,
sentiment VARCHAR(20),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
3. app.py dengan MySQL
from flask import Flask, render_template, request
from flask_mysqldb import MySQL
from textblob import TextBlob
app = Flask(__name__)
# Konfigurasi MySQL
app.config['MYSQL_HOST'] = 'localhost'
app.config['MYSQL_USER'] = 'root' # Ganti sesuai user MySQL kamu
app.config['MYSQL_PASSWORD'] = '' # Ganti jika ada password
app.config['MYSQL_DB'] = 'sentiment_db'
mysql = MySQL(app)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/analyze', methods=['GET', 'POST'])
def analyze():
result = None
if request.method == 'POST':
text = request.form['text']
blob = TextBlob(text)
polarity = blob.sentiment.polarity
if polarity > 0:
result = 'Positif'
elif polarity < 0:
result = 'Negatif'
else:
result = 'Netral'
# Simpan ke database
cur = mysql.connection.cursor()
cur.execute("INSERT INTO sentiment_log (text, sentiment) VALUES (%s, %s)", (text, result))
mysql.connection.commit()
cur.close()
return render_template('analyze.html', result=result)
@app.route('/about')
def about():
return render_template('about.html')
if __name__ == '__main__':
app.run(debug=True)
@app.route('/history')
def history():
cur = mysql.connection.cursor()
cur.execute("SELECT * FROM sentiment_log ORDER BY created_at DESC")
logs = cur.fetchall()
cur.close()
return render_template('history.html', logs=logs)
