Error when displaying follow/unfollow button

I am getting errors when I try to display follower counts and follow/unfollow buttons.

If I remove the if/else statement then the counts display as follows: https://www.dropbox.com/s/napzcmrxzmwmwet/Screenshot.png?dl=0

Then, I add in the logic for the follow/unfollow buttons, i get this: https://www.dropbox.com/s/1goq80coikp8qg6/Screenshot1.png?dl=0

or this, if I add the ending parentheses on current_user.following: https://www.dropbox.com/s/o45ibp0txmjyzg4/Screenshot2.png?dl=0

My models.py file is identical to that given in the course download (I even tried copy and pasting to see if I was missing something that wasn't obvious).

user_stream.html

{% extends "stream.html" %}

{% block content %}
<div class="row">
    <div class="grid-25">
        <h1>{{ user.username }}</h1>
    </div>
    <div class="grid-50">
        <div class="grid-33">
            <h5>Posts</h5>
            <p>{{ user.posts.count() }}</p>
        </div>
        <div class="grid-33">
            <h5>Followers</h5>
            <p>{{ user.followers.count }}</p>
        </div>
        <div class="grid-33">
            <h5>Following</h5>
            <p>{{ user.following.count }}</p>
        </div>
    </div>
    <div class="grid-25">
        <!-- Follow/unfollow button -->
        {% if current_user.is_authenticated %}
            {% if user != current_user %}
                {% if not user in current_user.following %}
                    <a href="{{ url_for('follow', username=user.username) }}" class="small">Follow</a>
                {% else %}
                    <a href="{{ url_for('unfollow', username=user.username) }}" class="small">Unfollow</a>
                {% endif %}
            {% endif %}
        {% endif %}
    </div>
</div>

{{ super() }}
{% endblock %}

I got it working! Apparently, my followers and following methods in models.py needed @property decorators. Can anyone explain why that is? Kenneth Love ???

That's a good question, especially on a course I'm no longer really familiar with. Let me do some searching and I'll get back to you.

Hmm, my only guess ATM is that something changed in Peewee. But based on what you have up there, would {{ user.following().count() }} work?
