Sending email using flask

I am using flask to send emails to user who submits a form in a contact page.

I have tried to test it myself but even If i fill the whole form. Every time I hit submit, I get a validation error saying that I must fill in the form. In my log it says I get a 200, which means the post was a success.

Here is the code:

routes.py

from flask import Flask, render_template, request, flash
from forms import ContactForm
from flask.ext.mail import Message, Mail


mail = Mail()

app = Flask(__name__)

app.secret_key = 'development key'

app.config["MAIL_SERVER"] = "smtp.gmail.com"
app.config["MAIL_PORT"] = 465
app.config["MAIL_USE_SSL"] = True
app.config["MAIL_USERNAME"] = 'contact@gmail.com'
app.config["MAIL_PASSWORD"] = '*********'

mail.init_app(app)


app = Flask(__name__)
app.secret_key = 'development key'

@app.route('/contact', methods=['GET', 'POST'])
def contact():
  form = ContactForm()

  if request.method == 'POST':
    if form.validate() == False:
      flash('All fields are required.')
      return render_template('contact.html', form=form)
    else:
      msg = Message(form.subject.data, sender="contact@gmail.com")
      msg.body = """
      From: %s <%s>
      %s
      """ % (form.name.data, form.email.data, form.message.data)
      mail.send(msg)

      return 'Form posted.'

  elif request.method == 'GET':
    return render_template('contact.html', form=form)

Forms.py

from flask.ext.wtf import Form
from wtforms import Form, TextField, TextAreaField, SubmitField, validators, ValidationError

class ContactForm(Form):
  name = TextField("Name", [validators.Required("Please Enter Your Name")])
  email = TextField("Email",[validators.Required("Please enter your email address"), validators.email("Please enter your email address")])
  subject = TextField("Subject", [validators.Required("Please enter a subject.")])
  message = TextAreaField("Message", [validators.Required("Please enter a message.")])
  submit = SubmitField("Send")
