Clear and simple rescue

jqr · Feb 14, 20091 thank

noxyu3m, your code is rescuing all exceptions, not just ActiveRecord::RecordInvalid.

I think this syntax is a bit more clear than using the global variable.

def create
@model = Model.new(params[:model)
@model.save!
rescue => err                          # rescues all exceptions
logger.error(err.to_s)
end

Simple rescue

Take it easy:

def create
@model = Model.new(params[:model)
@model.save!
rescue
logger.error(!$.to_s)
end

Global variable !$ refers to the Exception object.

Using global $! to address exception

schmidt · Apr 15, 2009

@noxyu3m: Your code is actually syntactically wrong. The global is called $!

Your code should have been:

def create
@model = Model.new(params[:model)
@model.save!
rescue
logger.error($!.to_s)
end

Although I would prefer

def create
@model = Model.new(params[:model)
@model.save!
rescue ActiveRecord::RecordInvalid
logger.error($!.to_s)
end

to only catch expected exceptions, just like the documentation proposed.
