Custom Error Handling for the Substitution parameter of MedicationRequest

[Tyler Y]

Hello,

I am working on a Create MedicationRequest, using the Hapi Fhir JPA Server. For the optional parameter Substitution, I want to throw custom error exceptions when invalid input is set to it during the POST request. But it seems like whenever there is invalid input for the Substitution parameter, the MedicationRequest just pretends like there was no input for that parameter (MedicationRequest.hasSubstitution() is not true). Does anyone have any suggestions?

Thanks

What kind of invalid input do you mean? If you mean just plain invalid FHIR content, you could use the RequestValidatingInterceptor to accomplish this. If it's valid FHIR but invalid because of business rules you have, you could also write a custom interceptor to throw a PreconditionFailedException or similar.

Looking at the source for RequestValidatingInterceptor might be useful if you go that route.

Cheers,

James

Thank you for your suggestions James. The substitution field has a parameter allowedBoolean, and I was trying to thrown an exception when this parameter was missing or when a string was put instead.
