Clear and simple rescue
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
@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.
