DjangoLDP reference guide

The DjangoLDP commands

The djangoldp server is built ontop of django framework. The django core commands are also available. Check python manage.py –help and [the official Django documentation](https://docs.djangoproject.com/en/2.2/)

The Initserver command

This command initiate a new server folder from a template. It has the minimal option to work out of the box.

The Configure command

This is a command meant to tell the server the settings have changed and it must run some maintenance operations and data integrity check, such as the model migration of the LDP packages.

It has options to create new administrator users during the configuration process.

The Install command

This command parses the dependencies section of the configuration file and install all python distribution required by the project. It is a wrapper around the requirements.txt file.

The runserver command

This command loads the configuration and starts the LDP server. It is a wrapper around the django-admin runserver command.

The startpackage command

This a helper command working the same way the django startpackage does command. It creates a folder with a DjangoLPD package template.

The DjangoLDP configuration file

The server comes with a default settings.yml you can customize.

It contains 3 main sections:

  • dependencies: contains a list of dependencies to install with pip during the install phase

  • ldppackages: contains a list of djangoldp packages to activate

  • server: contains all the configuration required by djangoldp server

You need to restart the server after a change in configuration.

The Dependencies section

This is not mandatory as you can install all your dependencies manually. But it is convienent to have all in one file when exchanging server configurations.

The format for dependencies is the one accepted by pip. For example:

dependencies:
  - git+https://git.startinblox.com/djangoldp-packages/djangoldp-account.git

As for any python project when you declare a dependency you have to make sure it is installed. You can use the wrapper command djangoldp install for this.

The LDP packages section

When you want to use a LDP package you need to reference it in the configuration. For example:

ldppackages:
  - djangoldp_account

The name referenced there must be the name of the python module, the one your would use with the import statement.

Some packages may require some configuration to work properly. It is a good practice to run the djangoldp configure command after adding or upgrading a LDP package.

Here you have :

If the description of the available packages is unclear, open an issue to ask for more description.

The Server section

This section contains all parameters to the server itself. All this section is loaded as a Django configuration object to initialize the server.

see https://docs.djangoproject.com/fr/2.2/topics/settings/

The extra config module

The DjangoLDP server also load a settings.py module when it exists in along with the settings.yml.

The DjangoLDP packages capabilities

Among other things, the package has a special file allowing a package to load settings when the djangoldp server starts. The djangoldp_settings.py file can reference custom variables and load extra middlewares (they are added to the ones loaded by the djangoldp server itself).

` # cat mypkg/mypkg/djangoldp_settings.py MIDDLEWARE = [] MYPACKAGE_VAR = 'MY_DEFAULT_VAR' `

As any other packages, local packages needs to be referenced in the project settings.yml: ``` ldppackages:

  • mypkg

```
