Add current_user Check, Build a Social Network with Flask

I don't think I understood how to create menus with links to these pages. Can anyone explain me what is the issue with this code?

<!doctype html>
<html>
<head>
<title>Lunch</title>
</head>
<body>

<nav>
  {% if current_user.is_authenticated %}
  <a href="{{ url_for('logout') }}" class="icon-power" title="Log out"></a>
  {% else %}
  <a href="{{ url_for('login) }}" class="icon-power" title="Sign In"></a>
  <a href="{{ url_for('register') }}" class="icon-power" title="Sign Up"></a>
  {% endif %}

<!-- Add menu here -->
</nav>

<div class="messages">
{% with messages = get_flashed_messages() %}
{% for message in messages %}
<div>{{ message }}</div>
{% endfor %}
{% endwith %}
</div>

{% block content %}{% endblock %}
</body>
</html>

The words "Sign Out", "Sign In", "Sign Up" should go in between the opening and closing anchor tags. These are the words that will appear on the screen and will be linked to the view. You were also missing a closing quote marking for 'login'. 

<nav>
  {% if current_user.is_authenticated %}
  <a href="{{ url_for('logout') }}" class="icon-power">Sign Out</a>
  {% else %}
  <a href="{{ url_for('login') }}" class="icon-power">Sign In</a>
  <a href="{{ url_for('register') }}" class="icon-power">Sign Up</a>
  {% endif %}
</nav>

You are very close. Two typos and syntax issue:

  {% if current_user.is_authenticated() %}  {# <-- add missing parens #}
  <a href="{{ url_for('logout') }}" class="icon-power" title="Log out"></a>   {# <-- Change to 'Sign Out' #}
  {% else %}
  <a href="{{ url_for('login') }}" class="icon-power" title="Sign In"></a>   {# <-- add missing quote after login #}
  <a href="{{ url_for('register') }}" class="icon-power" title="Sign Up"></a>
  {% endif %}

Like the formatting here? Surround your code block with ```html+jinja and ```

Guys, both of you were really helpful! Thank you so much. I was stuck on this bit for a while. Couldn't really move on :)
