Has anyone used `Flask-Security` extension for authentication? How do I get register view to work? 

<http://packages.python.org/Flask-Security/customizing.html>

I am referring to link above.

```
 @app.route('/register', methods=['GET'])
 def register():
     return render_template('security/register_user.html')

```

I don't want to extend the default class, I just want to wrap the default registration view in my site layout so I did this. 

```
{% extends "layout.html" %}
{% block title %}upload{% endblock %}
{% block body %}

{% from "security/_macros.html" import render_field_with_errors, render_field %}
{% include "security/_messages.html" %}
<h1>Register</h1>
<form action="{{ url_for_security('register') }}" method="POST" name="register_user_form">
{{ register_user_form.hidden_tag() }}
{{ render_field_with_errors(register_user_form.email) }}
{{ render_field_with_errors(register_user_form.password) }}
{% if register_user_form.password_confirm %}
   {{ render_field_with_errors(register_user_form.password_confirm) }}
{% endif %}
{{ render_field(register_user_form.submit) }}
</form>
{% include "security/_menu.html" %}

{% endblock %}

```

And I am getting the following error?

```
werkzeug.routing.BuildError
BuildError: ('security.register', {}, None)

```
