FHIR field for Plone

Project description

Egg Status Travis Build Status Test Coverage Python Versions Latest Version License https://img.shields.io/badge/code%20style-black-000000.svg

Background (plone.app.fhirfield)

FHIR (Fast Healthcare Interoperability Resources) is the industry standard for Healthcare system. Our intend to implement FHIR based system using Plone! plone.app.fhirfield will make life easier to create, manage content for FHIR resources as well search facilities for any FHIR Resources.

How It Works

This field is working as like other zope.schema field, just add and use it. You will feed the field value as either json string or python dict of FHIR resources through web form or any restapi client. This field has built-in FHIR resource validator and parser.

Example:

from plone.app.fhirfield import FhirResource
from plone.supermodel import model

class IMyContent(model.Schema):

    <resource_type>_resource = FhirResource(
        title=u'your title',
        desciption=u'your desciption',
        fhir_release='any of FHIR release name'
        resource_type='any fhir resource type[optional]'
    )

The field’s value is the instance of a specilized class FhirResourceValue inside the context, which is kind of proxy class of fhir model with additional methods and attributes.

Features

  • Plone restapi support
  • Widget: z3cform support
  • plone.supermodel support
  • plone.rfc822 marshaler field support

Available Field’s Options

This field has got all standard options (i.e title, required, desciption and so on) with additionally options for the purpose of either validation or constraint those are related to FHIR.

fhir_release

Required: Yes

Default: None

Type: String

The release version of FHIR

Example: R4, STU3

resource_type

Required: No

Default: None

Type: String

The name of FHIR resource can be used as constraint, meaning that we can restricted only accept certain resource. If FHIR json is provided that contains other resource type, would raise validation error. Example: FhirResource(….,resource_type=’Patient’)

model

Required: No

Default: None

Type: String + full python path (dotted) of the model class.

Like resource_type option, it can be used as constraint, however additionally this option enable us to use custom model class other than fhirclient’s model. Example: FhirResource(….,model=’fhirclient.models.patient.Patient’)

index_mapping

Required: No

Default: None

Type: JSON

The custom index mapping, best case is elasticsearch mapping. Default mapping would be replaced by custom.

Field’s Value API

Field’s value is a specilized class plone.app.fhirfield.value.FhirResourceValue which has reponsibilty to act as proxy of fhirclient model’s class. This class provides some powerful methods.

FhirResourceValue::json

Originally this method is derived from fhir base model, you will always have to use this method during negotiation (although our serializer doing that for you automatically). This method not takes any argument, it returns FHIR json representation of resource.

FhirResourceValue::patch

If you are familar with FHIRPath Patch, this method one of the strongest weapon of this class. Patch applying on any FHIR resources is noting but so easy. This method takes one mandatory argument patch_data and that value should be list of patch items (jsonpatch).

Example:

from plone.app.fhirfield import FhirResource
from plone.supermodel import model

class ITask(model.Schema):

    resource = FhirResource(
        title=u'your title',
        desciption=u'your desciption',
        resource_type='Task'
    )

patch_data = [
  {'op': 'replace', 'path': '/source/display', 'value': 'Patched display'},
  {'op': 'replace', 'path': '/status', 'value': 'Reopen'}
]
task_content.resource.patch(patch_data)

FhirResourceValue::stringify

This method returns string representation of fhir resource json value. Normally as_json returns python’s dict type data. This method takes optional prettify argument, by setting this argument True, method will return human/print friendly representation.

FhirResourceValue::foreground_origin

There may some situation come, where you will need just pure instance of fhir model, this method serves that purpose. This method returns current fhir resource model’s instance.

Example:

from fhirclient.models.task import Task
from plone.app.fhirfield import FhirResource
from plone.supermodel import model

class ITask(model.Schema):

    resource = FhirResource(
        title=u'your title',
        desciption=u'your desciption',
        resource_type='Task'
    )

task = task_content.resource.foreground_origin()
assert isinstance(task, Task)

Installation

Install plone.app.fhirfield by adding it to your buildout:

[buildout]

...

eggs =
    plone.app.fhirfield

and then running bin/buildout. Go to plone control and install plone.app.fhirfield or If you are creating an addon that depends on this product, you may add <dependency>profile-plone.app.fhirfield:default</dependency> in metadata.xml at profiles.

Migration

1.0.0 to 2.0.0

  1. Simply old indexes are not usable any more! as new ES server (6.x.x) is used.
  2. Do backup of your existing Data.fs (important!).
  3. From plone controlpanel, Go to elasticsearch settings page /@@elastic-controlpanel.
  4. Convert Catalog again, make sure in the Indexes for which all searches are done through ElasticSearch section your desired indexes are select.
  5. If your site is behind the proxy, we suggest make ssh tuneling to connect your site. Because next takes much times, (depends on your data size)
  6. Rebuild Catalog && wait for success, if you face any problem try again.

1.0.0rc3 to 1.0.0rc4

  1. Keep backup of existing Data.fs (nice to have)
  2. Go to plone control panel’s Addon settings
  3. Uninstall and Install again plone.app.fhirfield

1.0.0b6 to 1.0.0rc3

  1. Keep backup of existing Data.fs (important)
  2. Just Clear and Rebuild existing catalogs. Go to site management -> portal_catalog -> Advanced Tab and click the Clear and Rebuild button. Caution: this activity could take longer time.

1.0.0bx to 1.0.0b6

  1. You will need to remove all the indexes who are based on Fhir*******Index. Go to ZMI to portal catalog tool. {site url}/portal_catalog/manage_catalogIndexes.
  2. Update the plone.app.fhirfield version and run the buildout.
  3. List out any products those defined (profile/catalog.xml) indexes based on Fhir*******Index as meta type. Reninstall them all.
  4. From ZMI, portal_catalog tool, {site url}/portal_catalog/manage_catalogAdvanced Clear and Rebuild
