How to package a Django application as an addon¶
Register the addon¶
Before your addon can be uploaded, the Divio Cloud must be ready to receive it.
- Package Name: must be unique on the system. We recommend prefixing it with your own name, for
- Name: e.g.
Susan's Django Debug Toolbar
- License: select a predefined license for your addon (or leave it blank and add your own later.)
- Organisation: select an organisation if appropriate.
When you hit Create addon, the addon will be registered on the system.
The package name must not contain underscores. See the note in the addon packaging tutorial for more information.
Add the packaging files¶
We need to work in the project’s
addons-dev directory. Create a new
directory there with the same name as the Package Name.
Select Package Information from your addon’s menu. Download the packaging files, and add them to the addon. 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
Now let’s go through the files one by one.
All the lines you need in the setup.py will be provided automatically in
the downloaded version, with the exception of the
If your addon installs an application¶
In this case, you will need to add the package to be installed to the
install_requires argument, for example
If your addon contains an application¶
If on the other hand, for example if the application is not available on PyPI, simply add it as the inner application directory.
The inner application directory, in this case
susan_example_application, should have a
name that matches the package name (
susan-example-application), with underscores
substituted for the dashes.
This will allow the Control Panel to copy the application’s templates into the project’s Git repository when the addon is first installed in a project. If the names don’t match, the project will still work, but the templates will not be made available for easy editing.
The addon will then contain some additional files:
addons-dev/ susan-example-application/ [...] susan_example_application/ __init__.py admin.py apps.py migrations/ __init__.py models.py tests.py views.py
Add any dependencies of the application to
setup.py expects to find a version number in the addon, at
For an addon that installs a package¶
We recommend providing a version number that tracks the package’s version
number - for example, if the addon installs version
1.8.3, the addon’s
__version__ numbers should be
184.108.40.206 and so on.
For an addon that includes a package¶
We recommend some form of semantic versioning.
The other packaging files¶
The other packaging files are simpler:
README.rst: If you haven’t already provided a description via the Control Panel, this will be empty. If you plan to share your addon with other users, it’s important to provide a useful README.
MANIFEST.in: The default
MANIFEST.intakes care of most non-Python files that an addon is likely to need the setup tools to take care of:
LICENSE, plus directories for LICENSE, plus directories for
LICENSE: Make sure the license terms are appropriate.
addon.json: We recommend leaving this as it is. Although you can use it to add multiple packages to
INSTALLED_APPS, it’s better to do this in
If your application requires any settings of its own, you will need to manage
aldryn_config.py, placed at the root of your application. The general form is:
from aldryn_client import forms class Form(forms.BaseForm): def to_settings(self, data, settings): settings['INSTALLED_APPS'].extend([SOME_APPLICATION]) settings['ENABLE_FLIDGETS'] = True return settings
See how to configure settings in aldryn_config.py for more details and examples.
Provide form-based configuration¶
You can use the
Form class to allow configuration via the Control Panel.
See adding form fields for user configuraion for more information.
Check the addon¶
Your addon is now ready to be tested.
Add the package name to the
adds it to the list of addons that the project will “watch”.
divio project develop <package name>
You can test that the project now works as expected.
Now make sure you’re in the
addons-dev/<package name> directory.
divio addon validate should now confirm that the addon is
➜ divio addon validate Addon is valid!
Upload the addon¶
divio addon upload.
This version of the addon will be placed into the Alpha release channel. If you visit the its Versions page, you’ll be able to change the release channel.
Your addon is now available for installation into projects via the control panel. If you make it public, other users will be able to install it too.
You can continue uploading new versions of it, as long as each has its own unique version number.
