Custom Views that Require User Login

If you need to reach out to Globus Services, such as Transfer, users will need to be pre-authenticated so the portal can use their tokens. Django has built-in functions to check this, but needs some tuning to work with Python-Social-Auth.

Make sure you have a working portal with Globus Auth. If not, checkout the quick start here.

Add these additional settings to your settings.py. This will set the Django default, and allow the Django @login_required decorator to be used.

LOGIN_URL = '/login/globus'

Now, you can define your views like this:

from django.shortcuts import render
from django.contrib.auth.decorators import login_required
from globus_portal_framework.gclients import load_transfer_client


@login_required
def my_view(request, index):
    tc = load_transfer_client(request.user)
    mypaths = tc.operation_ls('ddb59aef-6d04-11e5-ba46-22000b92c6ec', path='/share/godata')
    context = {'mypaths': mypaths}
    return render(request, 'mypaths.html', context)

If your user encounters my_view above, the @login_required decorator will redirect them to the LOGIN_URL defined in your settings.py

If you want to prevent unauthenticated users from even navigating to your views in the first place, you can disable links in templates.

<nav>
  <ul class="nav nav-tabs">
    <li class="nav-item">
      <a class="nav-link" href="{% url 'my-landing-page' globus_portal_framework.index %}">About {{project_title}}</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="{% url 'my-projects-page' globus_portal_framework.index %}">Projects</a>
    </li>
    <li class="nav-item">
      <a class="nav-link" href="{% url 'my-search' globus_portal_framework.index %}">Search</a>
    </li>
    <li class="nav-item">
      <a class="nav-link
        {% if not request.user.is_authenticated %}
        disabled
        {% endif %}
      " href="{% url 'my-files' globus_portal_framework.index %}">View My Files</a>
    </li>
  </ul>
</nav>

In this example using Bootstrap, the "View My Files" link will be disabled.
