Sequel::Model does not currently have a method for finding the first
matching instance or raising an exception. Historically, the methods that
return individual rows return nil if no rows match. I think that's a good
default, but in some cases you want an error to be raised (akin to
ActiveRecord::RecordNotFound).
I'd like this method to basically be the following code:
def (Sequel::Model).METHOD_NAME(*args)
self[*args] || raise Sequel::EXCEPTION_NAME
end
My main concern when adding this method is naming. What should the method
and exception names be?
Method naming is problematic. .find is already used and works differently,
same with .first. Using .find! or .first! is problematic as that implies
the method works just like .find or .first, and .[] operates differently.
.[]! is not valid syntax. If anyone has suggestions for the method name,
please speak up.
Exception naming I'm not very concerned with. We could be just like
ActiveRecord and use Sequel::RecordNotFound, but I'm open to suggestions
there as well.
Thanks,
Jeremy
