Indention Error?

When I attempt to use the console to run python app.py it sends me an error saying I have an indention error with line 61, please help!

Here is the error: treehouse:~/workspace$ python app.py
File "app.py", line 62
models.initialize()
^
IndentationError: expected an indented block

Here is the app.py file:

from flask import Flask, g, render_template, flash, redirect, url_for
from flask.ext.login import LoginManager

import forms
import models

DEBUG = True
PORT = 8000
HOST = '0.0.0.0'


app = Flask(__name__)
app.secret_key = 'b3478tohfre87fvsd87fqw78nf378nc~!'

login_manager = LoginManager()
login_manager.init_app(app)
login_manager.login_view = 'login'


@login_manager.user_loader
def load_user(userid):
  try:
    return models.User.get(models.User.id == userid)
  except models.DosNotExist:
    return None



@app.before_request
def before_request():
  g.db = models.DATABASE
  g.db.connect()



@app.after_request
def after_request(responce):
  g.db.close()
  return responce



@app.route('/register', methods=('GET', 'POST'))
def register():
  form = forms.RegisterForm()
  if form.validate_on_submit():
    flash("Yay, you registered!", "success")
    models.User.create_user(
      username=form.username.data,
      email=form.email.data,
      password=form.password.data
    )
    return redirect(url_for('index'))
  return render_template('register.html', form=form)

@app.route('/')
def index():
  return 'Hey'


if __name__ == '__main__':
models.initialize()
models.User.create_user(
  username='trent',
  email='taylor@coldcodr.com',
  password='password',
  admin=True
)

app.run(debug=DEBUG, host=HOST, port=PORT)

The indentation in your final if statement is off. Fix the indentation in the following block of code:

if __name__ == '__main__':
models.initialize()
models.User.create_user(
  username='trent',
  email='taylor@coldcodr.com',
  password='password',
  admin=True
)

edit:

Also make sure this line has the proper indentation:

app.run(debug=DEBUG, host=HOST, port=PORT)

app.run is supposed to be indented one level as well so that it belongs to the if statement.

Fixed! Thanks. Now, can you tell me how to start the app/server so that I can preview my work

Trenton,

Are you still having an issue with running it?
