Class Method Details

.annotate_exception(exc, options = {}) ⇒ Object Also known as: annotateException, annotate

Provides extra context to the exception prior to it being handled by Raven. An exception can have multiple annotations, which are merged together.

The options (annotation) is treated the same as the “options“ parameter to “capture_exception“ or “Event.from_exception“, and can contain the same “:user“, “:tags“, etc. options as these methods.

These will be merged with the “options“ parameter to “Event.from_exception“ at the top of execution.

Examples:

begin
  raise "Hello"
rescue => exc
  Raven.annotate_exception(exc, :user => { 'id' => 1,
                           'email' => '[email protected]' })
end

  notes = exc.instance_variable_get(:@__raven_context) || {}
  notes.merge!(options)
  exc.instance_variable_set(:@__raven_context, notes)
  exc
end

.capture(options = {}, &block) ⇒ Object

Capture and process any exceptions from the given block, or globally if no block is given

Examples:

Raven.capture do
  MyApp.run
end
