A little help required regarding FHIR DSTU2

[abdulazizibrahim]

Hi fellows,

I am new to the whole health-tech world and I had to work FHIR DSTU2 version. I was using this library to test out stuff and I faced some issues which I will addressing below and I hope you guys can help me out here.

`
from fhir.resources.DSTU2.subscription import Subscription

data = {

"resourceType": "Subscription",

"id": "1882f571-520c-4c07-ba41-9b83fdb4eb3d",

"criteria": "ReferralRequest?_practitioner=Beck,Rachel MD&_encounter=Encounter/27300-AM0000120709",

"reason": "callback",

"channel": {

    "type": "rest-hook",

    "endpoint": "TBD",

    "payload": "application/json"

}

}

sub = Subscription(**data)
When I receive a subscription request (json), I want to create an FHIR Subscription object but when I try to do that I get the following error.
ValidationError Traceback (most recent call last)
in
----> 1 sub = Subscription(**data)

~/.local/lib/python3.9/site-packages/fhir/resources/DSTU2/fhirabstractmodel.py in init(pydantic_self, **data)
134 )
135 if errors:
--> 136 raise ValidationError(errors, pydantic_self.class)
137
138 BaseModel.init(pydantic_self, **data)

ValidationError: 1 validation error for Subscription
resource_type
Wrong ResourceType: fhir.resources.DSTU2.subscription.Subscription expects resource type Substance, but got Subscription. Make sure resource type name is correct and right ModelClass has been chosen. (type=value_error.wrong.resource_type; error=fhir.resources.DSTU2.subscription.Subscription expects resource type Substance, but got Subscription. Make sure resource type name is correct and right ModelClass has been chosen.)

I would really appreciate if you could help me out here. @nazrulworld

@abdulazizibrahim I see it's not your fault in any way, it's a bug. Please open an issue, we will look into it.
For now, you could make a simple override/patch to continue.

from fhir.resources.DSTU2.subscription import Subscription as OrgSubscription
class Subscription(OrgSubscription):
     resource_type = Field("Subscription", const=True)

Actuality DTU2 package is not properly tested. If possible You can check other classes as well.

@nazrulworld Yes, i will do that. Also I was looking through the repo and I think if you go to file fhir.resources/fhir/resources/DSTU2/subscription.py you will find resourse_type = Field("Substance", const=True ) on line 27. I think it may have something to do with it.
