I have started just learning Flask and tried to find an answer how to post to SQLite DB from webform. So far haven't managed to get it work and bit lost with this. I manage to print values from DB based on code sample from simplypython but don't know how to add new ones from webform.
I would need to be able to address elements, open connection to the database, Insert values, save and close the connection. As far as I am aware I should add the POST method to the app.py and use request.form statement to pull the elements when submit button is pressed.
then the code should automatically display all the values on index html, which already works. could you please help me with the code I need to add to app.py file to get values added to DB and what to add to form action webform-section on html file?
index.html

posts = [dict(title=row[0], description=row[1]) for row in cur.fetchall()]
g.db.close()
return render_template("index.html", posts=posts)
if __name__=='__main__':
app.run(debug=True)
sql.py
import sqlite3
with sqlite3.connect("sample.db") as connection:
c = connection.cursor()
c.execute("DROP TABLE posts")
c.execute("CREATE TABLE posts(title TEXT, description TEXT)")
c.execute('INSERT INTO posts VALUES("well", "no luck.")')
