Using Teams

Teams are designed to provide sandboxes for groups of users collaborating on single project. Users can join one or more teams, invite other users to their teams, and give different team members different roles.

Pegasus provides the building blocks to setup a team-based application. Some of those building blocks are documented here.

Note: all of the following examples assume you have setup Pegasus with teams enabled.


Teams use three primary models - apps.users.CustomUser, apps.teams.Team, and apps.teams.Membership.

The Membership model uses Django’s “through” support to extend the User/Team relationship with additional fields.

By default, a role field is added to represent the User’s role in the Team (admin or member).

Team-based Views

At its core, all Team-based views need the following:


See apps.web.urls for an example of these. The convention Pegasus uses is to make all team-based URLs of the form<team_slug>/. The team_slug is a human-readable, URL-friendly version of the team name that is auto-generated for you.


See apps.web.views for example team views. The most important elements of a team-based view are permissions.

Team permissions are not managed for you but have to be explicitly set on your views (and data models).

Permission Decorators

Pegasus includes two convenience decorators for use in team views. These can be found in apps.teams.decorators.

The login_and_team_required decorator

This decorator can be used to ensure that the logged in user has access to the team in the view. It requires your view’s first argument be team_slug, as in the example views. It can be used like this:

def a_team_view(request, team_slug):
    # other view logic here
    return render(request, 'web/my_template.html', context={

Note that will automatically be populated. If the current user does not have access to the team they will see a 404 page. If no user is logged in they’ll be redirected to a login view, just like the login_required decorator.

The team_admin_required decorator

The team_admin_required decorator works just like the login_and_team_required decorator, except in addition to checking team membership the role is also checked and if the user doesn’t have “admin” access they will not be able to access the view.


The above decorators offer special exemptions for Django superusers, who are allowed to access all teams and all pages by default.

Template tags

In addition to the decorators, you can also use template tags to check user / team access from a template.

This can be useful for hiding/showing certain content based on a user’s team role. The is_member_of filter can be used to check team membership, and the is_admin_of filter can be used to check if a user is a team admin. For example, the following will show only if the logged in user is an admin of the associated team:

{% load team_tags %}
{% if team and request.user|is_admin_of:team %}
  <p>You're an admin of {{}}.</p>
{% elif team and request.user|is_member_of:team %}
  <p>You're a member of {{}}.</p>
{% else %}
  <p>Sorry you don't have access to {{}}.</p>
{% endif %}
