Step-by-step guides to some different things you might want to do with Pegasus.

Use the Django Admin UI#

Pegasus ships with a simple script to promote any user to a superuser who can access the Django admin.

After going through the sign up flow, to convert your newly-created user into an admin, run the following command, being sure to replace the email address with the one you used to sign up:


docker compose exec web python ./ promote_user_to_superuser


python ./ promote_user_to_superuser

Now you should be able to access the django admin at http://localhost:8000/admin

Migrating to auto-formatted code#

As of February, 2023 all Pegasus projects have the option to auto-format your Python code.

To migrate a project from non-formatted to formatted code, you can go through the following steps:

  1. First, do a full Pegasus upgrade to the version you want to update to, as described here. Do not check the “autoformat” checkbox yet.

  2. Next, run the formatting tools on your project’s main branch:

    1. Install black and isort: pip install black isort

    2. Run black: black --extend-exclude migrations --line-length 120 .

    3. Run isort: isort -l 120 --profile black .

  3. Commit the result:

    1. git add .

    2. git commit -m "apply formatting changes"

  4. Finally, check the “autoformat” box on your Pegasus project, and do another upgrade according to the same process.

Delete Pegasus Examples#

On versions 2023.2 and later, you can remove the Pegasus examples by unchecking the “Include Examples” checkbox on your project page and re-downloading (or upgrading) your codebase.

For earlier versions you can use the following instructions:

Remove the navigation elements#

To hide the examples, remove the link from apps/web/templates/web/components/top_nav.html linking to the Examples Gallery.

The exact code will depend on your selected CSS framework/theme, but will look something like this:

<li class="nav-item">
  <a class="nav-link {% if '/pegasus/' in request.path %}active{% endif %}" href="{% url 'pegasus_examples:examples_home' %}">
    {% translate "Examples Gallery" %}

Note that hiding the navigation won’t remove the examples. Your users could still find them by navigating to the /pegasus/ endpoint in a browser.

To remove the examples entirely, take the following additional steps:

Clean the back-end code#

  1. In, remove PEGASUS_APPS and the reference in INSTALLED_APPS.

  2. In your root, remove the lines containing include('pegasus.apps.examples.urls') and include('pegasus.apps.employees.urls').

  3. Delete the entire top-level pegasus/ directory.

  4. Delete the entire templates/pegasus/ directory.

Clean the front-end code#

  1. In webpack.config.js, delete the 'react-object-lifecycle', vue-object-lifecycle and 'pegasus' entries from module.exports.

  2. Delete the assets/javascript/pegasus/ folder.

  3. Delete assets/javascript/api-client/apis/PegasusApi.ts and remove it from assets/javascript/api-client/apis/index.ts

  4. Delete static/js/react-object-lifecycle-bundle.js, static/js/vue-object-lifecycle-bundle.js and static/js/pegasus-bundle.js
