got it .. and it's running well , may be not the best coding , but it
runs ....
in my config/initializers/custom_exceptions.rb
Module Exceptions
class RemoteContainerDenied < StandardError
def initialize(msg, remote_container_id, request_id , user_id)
super(msg)
@message = msg
@request_id = request_id
@remote_container_id = remote_container_id
@user_id = user_id
end
def message; @message + "remote_container_id:
#{@remote_container_id} , requestId: #{@request_id}"; end
def remote_container_id; @remote_container_id; end
def request_id; @request_id; end
def user_id; @user_id; end
end
end
raised with :
raise(RemoteContainerDenied.new("Access denied",
remote_container_id[:id], request[:id], user[:id] ) if response.nil?
et voilà ...
then I can trap these exceptions in delayed_job ( error hook) and act
according to the exception :
def error(job, exception)
case exception
when RemoteLockerDenied
AdminMailer.....
very awesome
