Hello, everyone!
I’m trying to use Cloud 9 to put together a demo project that has two text fields. One is for the user’s name and the other for their age. There are two buttons, ‘add’ and ‘retrieve’ that add the name/age to the database and retrieve a name/age from the database randomly.
I have my project routed to /, so it appears at the default project-username.c9users.io:8080 directory. When I type something in and hit submit/add, it redirects to project-username.c9users.io:8080/localhost/?name=blah&age=2398&submit=add for inputs 'blah' and 2398. Thus, it goes to a 404 page. I don’t understand why it is doing this.
Here is my code in its entirety.
import os
import sqlite3
from flask import Flask
from flask import request
from flask import render_template
from flask import g
app = Flask(__name__)
@app.route('/', methods=['POST', 'GET'])
def people():
error = None
if request.form.get('submit', None) == "add":
if request.method == 'POST':
if request.form['name'] and request.form['age']:
name = request.form['name']
age = request.form['age']
database = connect_db()
cursor = database.cursor()
sql = "INSERT INTO person (name, age) VALUES ({0}, {1});".format(name, age)
cursor.execute(sql)
database.commit()
return render_template("index.html")
else:
error = "Name or age not provided."
return render_template('index.html', error=error)
elif request.form.get('submit', None) == "retrieve":
if request.method == 'GET':
database = connect_db()
cursor = database.cursor()
sql = "SELECT * FROM person ORDER BY RANDOM() LIMIT 1;"
cursor.execute(sql)
result = cursor.fetchone()
return render_template("index.html")
return render_template("index.html")
def connect_db():
db = getattr(g, '_database', None)
if db is None:
connection = sqlite3.connect("./people.db")
db = g._database = connection
return db
@app.teardown_appcontext
def close_connection(exception):
db = getattr(g, '_database', None)
if db is not None:
return db.close()
if __name__ == "__main__":
app.run(host=os.getenv('IP', '0.0.0.0'),port=int(os.getenv('PORT', 8080)))
It’s SUPPOSED to enter this information into the database and then return back to this page to allow the user to do it again. How do I do that?
Thank you very much!
