Populate list data and other static model data on startup in clinicedc/edc projects

edc-list-data

Populate list data and other static model data on Django startup.

To install add edc_list_data.apps.AppConfig to your INSTALLED_APPS, then create a list_data.py in the root of your app.

Most commonly used to populate M2M data known here as list_data. M2M field models should use the ListModelMixin.

The list models are populated using a post_migrate signal. Once everything is configured or after changes are made, you need to run python manage.py migrate.

For example:

class Antibiotic(ListModelMixin, BaseUuidModel):

    class Meta(ListModelMixin.Meta):
        pass

An example list_data.py:

from edc_constants.constants import OTHER

list_data = {
    'my_lists_app.antibiotic': [
        ('flucloxacillin', 'Flucloxacillin'),
        ('gentamicin', 'Gentamicin'),
        ('ceftriaxone', 'Ceftriaxone'),
        ('amoxicillin_ampicillin', 'Amoxicillin/Ampicillin'),
        ('doxycycline', 'Doxycycline'),
        ('erythromycin', 'Erythromycin'),
        ('ciprofloxacin', 'Ciprofloxacin'),
        (OTHER, 'Other, specify')
    ],
}

Now run:

>>> python manage.py migrate

The list data will be populated in the order in which the list items are declared.
