Can this gem instantiate a new Patient object from json about fhir_client HOT 3 CLOSED

Here you go:

> patient_data = {resourceType: "Patient", id: "123"}
=> {:resourceType=>"Patient", :id=>"123"}
> patient = FHIR.from_contents(patient_data.to_json)
=> #<FHIR::Patient:0x00007f9a10f20ba0

I really appreciate the help. On a similar note, I'd like to be able to trap when an attempt to instantiate invalid data is made.
For instance, FHIR.from_contents '{"asdf":"asdf"}' returns the following ERROR -- : Failed to deserialize JSON:

But it doesn't raise an rescuable exception. Is there a way I can handle this? I might just be looking at it wrong. Thanks again

begin 
   FHIR.from_contents '{"asdf":"asdf"}'
rescue
   puts "error"
end

this doesn't rescue

from fhir_client.

The current API does not raise exceptions on parse errors. Instead, it will return nil.

asdf_resource = FHIR.from_contents '{"asdf": "asdf"}'

puts 'parse problem' if asdf_resource.nil?

If you would like it to behave that way, you could do something like this:

begin
   asdf_resource = FHIR.from_contents('{"asdf": "asdf"}') || raise
rescue
   puts 'error'
end

I think raising exceptions on invalid resources by default instead of returning nil would probably make more sense, and it would probably fix a whole class of problems in some of our test tools, but that's not how it is done right now.
