How to update an existing Aldryn addon

Addons will need to be updated now and then. The basic process for updating an addon is to:

Choose a local application to work with​

Ideally, select an application that already works with an existing version of the addon. This way, you can check that the new version continues to work as expected, and that migrations for example run correctly.

If you don't have such an application, the next best thing is to create a new application on the Control Panel containing the addon, and then set that up locally.

Uninstall the addon locally if necessary​

You will find the addon listed in requirements.in - remove it from there, so that when you build the local container it will no longer try to install the old version.

You will also find it listed in INSTALLED_ADDONS in settings.py - leave it there.

Clone the addon repository to addons-dev​

In addons-dev, clone the addon from its VCS repository. It should look something like this:

addons-dev/
    susan-example-application/
        addon.json
        LICENSE
        MANIFEST.in
        README.rst
        setup.py
        susan_example_application/
            __init__.py

Check that you have the appropriate version cloned.

Placing the addon into addons-dev will override any version that has been installed into the application using the requirements file.

Run divio app develop​

If the new version is different from the previously installed version and includes changed dependencies, or you want to check exactly what it will do when when the application is built, you should run:

divio app develop <package name>

This processes the addon, adding:

-e /app/addons-dev/<package name>

to the requirements.in.

You will need to run this again if you make any changes in the addon that involve dependencies or installation of components.

Work on the code​

Restart the runserver (docker compose up), and check that the addon continues to work as expected (or fails to work, if that is what previously happened).

Make and test any changes you want to make.

Push your changes​

When you're satisfied, you're ready to update the addon.

Don't forget to bump the version number in the __init__.py.

When you have finished all your updates, commit and push your changes to the addon's repository (or make a pull request if it's not your own).

Remember that if your addon is a wrapper for installing a reusable application, its version number should track the version number of the application, in an additional dotted increment - for example, the addon version 1.5.4.2 tracking application version 1.5.4 should become 1.5.4.3.

Upload the new addon version​

Finally, in the addon directory, run:

divio addon validate

to check it, and:

divio addon upload

to push it to the addons system.

Test it on the Control Panel​

For completeness, check that the new version of your addon can be installed and deployed in an application.

Place the new version in the appropriate channel​

By default, your newly-uploaded addon version will be placed in the Alpha channel. In the Addons section of the Control Panel, put it in the Beta or Stable channels if appropriate.
