Simple form submit python

Question

I have simple python app which gets name and phone from html form submit using post method. I have this in my index.html:

<form action="http://127.0.0.1:5000/get_phone/" method = "POST">
First name:
<input type="text" name="firstname" >
Phone:
<input type="text" name="lastname" >
<input type="submit" value="Submit">
</form>

And have my getPhone.py:

from flask import Flask
app = Flask(__name__)
@app.route('/get_phone/', methods=['POST', 'GET'])
def get_phone():
 if request.method == 'POST':
 print ('First name:', request.form['firstname'])
 print ('Phone:', request.form['lastname'])
 return 'Take a look at your terminal!'
if __name__ == '__main__':
 app.run()

But when I submit my form with I get the following message in my browser:

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

In my console I have this:

> * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
127.0.0.1 - - [04/Feb/2015 22:20:04] "GET /get_phone/ HTTP/1.1" 500 -

127.0.0.1 - - [04/Feb/2015 22:26:22] "GET /get_phone/ HTTP/1.1" 500 -

How to fix this?

UPD: consoleLog with debug = true:

 * Restarting with stat

• Sevanteri: Replace app.run() with app.run(debug=True) to get more information about what is going wrong. Though it seems the issue is that you haven't imported request.
• Joran Beasley: to clarify your likely issue that @Sevanteri referenced from flask import Flask,request
• user2950593: thanks it works=) import request i mean, can any of you write it as an answer so I can accept it?)

Answer 1

The issue is that you haven't imported request. Like this:

from flask import Flask, request

Answer 2

All variables that you put in a route you have to make sure that they are imported at the top of your flask route page.
