Instance Method Details

#cli_context(definition = nil) ⇒ Object

Set the cliContext used as part of each validation request. Fields may be passed as either a Hash or block. Note that all fields included here will be sent directly in requests, there is no check that the fields are correct.

Examples:

fhir_resource_validator do
  url 'http://example.com/validator'
  cli_context do
    noExtensibleBindingMessages true
    txServer nil
  end
end
fhir_resource_validator do
  url 'http://example.org/validator'
  cli_context({
    noExtensibleBindingMessages: true,
    txServer: nil
  })
end

Parameters:

  • definition (Hash) (defaults to: nil) —

    raw fields to set, optional

      @cli_context.instance_eval(&)
    end
  else
    @cli_context = CliContext.new(definition || {}, &)
  end
  @cli_context
end

#exclude_message {|message| ... } ⇒ Object

Filter out unwanted validation messages. Any messages for which the block evalutates to a truthy value will be excluded.

Examples:

validator do
  exclude_message { |message| message.type == 'info' }
end

  @exclude_message
end

#igs(*validator_igs) ⇒ Object

Set the IGs that the validator will need to load

Examples:

igs "hl7.fhir.us.core#4.0.0"
igs("hl7.fhir.us.core#3.1.1", "hl7.fhir.us.core#6.0.0")

Parameters:

  • validator_igs (Array<String>)

def igs(*validator_igs)
  cli_context(igs: validator_igs) if validator_igs

  cli_context.igs
end

#perform_additional_validation {|resource, profile_url| ... } ⇒ Object

Perform validation steps in addition to FHIR validation.

Examples:

perform_additional_validation do |resource, profile_url|
  if something_is_wrong
    { type: 'error', message: 'something is wrong' }
  else
    { type: 'info', message: 'everything is ok' }
  end
end

Yield Parameters:

  • resource (FHIR::Model) —

    the resource being validated

  • profile_url (String) —

    the profile the resource is being validated against

Yield Returns:

  • (Array<Hash<Symbol, String>>, Hash<Symbol, String>) —

    The block should return a Hash or an Array of Hashes if any validation messages should be added. The Hash must contain two keys: :type and :message. :type can have a value of 'info', 'warning', or 'error'. A type of 'error' means the resource is invalid. :message contains the message string itself.
