edc-sites 0.1.21

Simple classes related to the django sites framework for clinicedc projects.

edc-sites

Site definitions to work with Django’s Sites Framework and django_multisite.

Define a sites.py. This is usually in a separate project module. For example, for project meta there is a module meta_sites that contains a sites.py.

    # sites.py
from edc_sites.single_site import SingleSite

    fqdn = "example.clinicedc.org"

    meta_sites = (
        SingleSite(
            10,
            "hindu_mandal",
            title="Hindu Mandal Hospital",
            country="tanzania",
            country_code="tz",
            domain=f"hindu_mandal.tz.{fqdn}",
        ),
        SingleSite(
            20,
            "amana",
            title="Amana Hospital",
            country="tanzania",
            country_code="tz",
            domain=f"hindu_mandal.tz.{fqdn}",
        ),
    )

Register a post_migrate signal in apps.py to update the django model Site and the EDC model SiteProfile on the next migration:

# apps.py

from .sites import meta_sites, fqdn

def post_migrate_update_sites(sender=None, **kwargs):
    from edc_sites.add_or_update_django_sites import add_or_update_django_sites

    sys.stdout.write(style.MIGRATE_HEADING("Updating sites:\n"))
    add_or_update_django_sites(
        apps=django_apps, sites=meta_sites, fqdn=fqdn, verbose=True
    )
    sys.stdout.write("Done.\n")
    sys.stdout.flush()

For another deployment, we have alot of sites spread out over a few countries. In this case we pass a dictionary and separate the lists of sites by country.

For example:

fqdn = "inte.clinicedc.org"

all_sites = {
    "tanzania":(
        SingleSite(
            101,
            "hindu_mandal",
            title="Hindu Mandal Hospital",
            country="tanzania",
            country_code="tz",
            domain=f"hindu_mandal.tz.{fqdn}",
        ),
        SingleSite(
            102,
            "amana",
            title="Amana Hospital",
            country="tanzania",
            country_code="tz",
            domain=f"hindu_mandal.tz.{fqdn}",
        ),
    ),
    "uganda":(
        SingleSite(
            201,
            "kojja",
            country="uganda",
            country_code="ug",
            domain=f"kojja.ug.{fqdn}",
        ),
        SingleSite(
            202,
            "mbarara",
            country="uganda",
            country_code="ug",
            domain=f"mbarara.ug.{fqdn}",
        ),
    ),
}

In a multisite, multi-country deployment, managing the SITE_ID is complicated. We use django_multisite which nicely reads the SITE_ID from the url. django_multisite will extract kojja from https://kojja.ug.example.clinicedc.org to do a model lookup to get the SITE_ID.
