edc-mnsi

Django classes for the Michigan Neuropathy Screening Instrument (MNSI).

MNSI scores are calculated in signals.py through a call to the MnsiCalculator and stored in two calculated fields on the model. The two calculated fields can also be viewed as read only on the form in Admin.

edc_mnsi has an Mnsi model. If the default model does not meet your needs, you can use the Mnsi model mixin, MnsiModelMixin, and declare a custom Mnsi model in your app.

.. code-block:: python

# models.py
from edc_mnsi.model_mixins import MnsiModelMixin
from edc_model import models as edc_models
# a custom mixin
from ..model_mixins import CrfModelMixin


class Mnsi(
    MnsiModelMixin,
    CrfModelMixin,
    edc_models.BaseUuidModel,
):
    class Meta(MnsiModelMixin.Meta, CrfModelMixin.Meta, edc_models.BaseUuidModel.Meta):
        pass

Add the following to settings if using a custom Mnsi model::

EDC_MNSI_MODEL = "my_app.mnsi"

Note: settings.EDC_MNSI_MODEL is needed by edc_mnsi.auths.py to find the Mnsi model. This is applicable if you are using edc_auth.

A custom admin class will be needed for your custom Mnsi model. Here is an example of a custom admin class that refers to fields added to the custom Mnsi model and adds a custom modeladmin mixin.

Note: In your custom admin you should unregister the default admin class before registering your custom admin class.

.. code-block:: python

# admin.py
from django.contrib import admin
from django_audit_fields import audit_fieldset_tuple
from edc_crf.admin import crf_status_fieldset_tuple
from edc_mnsi.admin_site import edc_mnsi_admin
from edc_mnsi.fieldsets import calculated_values_fieldset
from edc_mnsi.fieldsets import get_fieldsets as get_mnsi_fieldsets
from edc_mnsi.model_admin_mixin import MnsiModelAdminMixin, radio_fields
from edc_mnsi.models import Mnsi as DefaultMnsi
from edc_model_admin.history import SimpleHistoryAdmin

# your app's admin site
from ..admin_site import my_app_admin
# your custom form
from ..forms import MnsiForm
# your custom model
from ..models import Mnsi
# a custom mixin
from .modeladmin import CrfModelAdmin

# customize the fieldsets as needed
def get_fieldsets():
    fieldset = (
        None,
        {
            "fields": (
                "subject_visit",
                "report_datetime",
                "mnsi_performed",
                "mnsi_not_performed_reason",
            )
        },
    )

    fieldsets = (fieldset,) + get_mnsi_fieldsets()
    fieldsets += (crf_status_fieldset_tuple,)
    fieldsets += (calculated_values_fieldset,)
    fieldsets += (audit_fieldset_tuple,)
    return fieldsets

# customize radio_fields
radio_fields.update(crf_status=admin.VERTICAL)
# unregister the default model
edc_mnsi_admin.unregister(DefaultMnsi)

@admin.register(Mnsi, site=meta_subject_admin)
class MnsiAdmin(
    MnsiModelAdminMixin,
    CrfModelAdmin,
    SimpleHistoryAdmin,
):
    form = MnsiForm
    fieldsets = get_fieldsets()
    radio_fields = radio_fields
