edc-locator

Base classes for participant locator form and processes

Other edc modules will use get_locator_model and get_locator_model_cls to access the subject locator model class. get_locator_model defaults to edc_locator.subject_locator. If you declare a custom locator model, add the name of the model to settings in label_lower format:

# settings.py
SUBJECT_LOCATOR_MODEL="myapp.subject_locator"

When declaring a custom locator model, you may only need to declare a proxy model class.

For example:

# models.py
from edc_locator.models import SubjectLocator as BaseModel


class SubjectLocator(BaseModel):
    class Meta:
        proxy = True
        verbose_name = "Subject Locator"
        verbose_name_plural = "Subject Locators"

# forms.py
# use the form class from edc_locator

Use the modeladmin mixin class SubjectLocatorModelAdminMixin. Since you only want one subject locator model accessible through admin in your EDC, unregister the default subject locator before registering your custom modeladmin class.

# admin.py
edc_locator_admin.unregister(DefaultSubjectLocator)

@admin.register(SubjectLocator, site=intecomm_prn_admin)
class SubjectLocatorAdmin(
    SubjectLocatorModelAdminMixin,
    SiteModelAdminMixin,
    ModelAdminSubjectDashboardMixin,
    SimpleHistoryAdmin,
):
    pass
