User groups in relation to categories

Question

I am building a community website that currently have two user groups but it might increase so I am trying to automate everything. The current groups are: 'teachers' & 'candidates'.

I have a channel section named 'Community' and for this channel I have setup a category group called 'Community' that has two categories named as the user groups: 'teachers' & 'candidates'.

I am trying to display a list of all the registered users in a specific group as you are loading the category template.

This is the template that is being loaded:

{% extends "community/index" %}

{% set title = category.title %}

{% block main %}

    <h1>{{ category.title }}</h1>

    {% set group = craft.users.group('{{ category.slug }}') %}

    {% for user in group %}
        <li>{{ user.name }}</li>
    {% endfor %}

{% endblock %} 

I was thinking that since the {{ category.slug }} has the same name as the user group, it can work but apparently not...

Can someone help me to understand how to relate the two?

Answer 1

I believe your problem lies in the parameter for user group. In Twig, you don't need the brackets if you're already in brackets. You just reference the variable and fields directly. So instead of:

{% set group = craft.users.group('{{ category.slug }}') %}

Try this:

{% set group = craft.users.group(category.slug) %}

You see, the ElementCriteriaModel that's parsing the parameter for group doesn't run all its function arguments through Twig. So you're confusing it by throwing braces in there. Just give it the variable and field without quotes or braces and it should work smashingly, provided that category.slug is the same as a group slug.
