Instance Method Details

#error(name, options) ⇒ Object

Describe an error.

name

The error name - the bit after the “.” in the code, e.g. invalid_parameters.

options

Options hash. See below.

The options hash contains symbol keys named as follows, with values as described:

:status

The integer or string HTTP status code to be associated with this error

message

The en-nz language human-readable error message used for developers.

reference

Optional array of required named references. When errors are added (via Hoodoo::Errors#add_error) to a collection, required reference(s) from this array must be provided by the error-adding caller else an exception will be raised. This ensures correct, fully qualified error data is logged and sent to clients.
