Question

I think I will want to use combine a model level finder with a lambda.

named_scope :recent_snaps, lambda {|since_when| {:conditions=>{:created_at >= since_when}}}

but I am not sure and also if I have the syntax correct, espcially for the parameter piece and can’t run the app right now to check at console.

I do not want to use a find_by_sql or a controller find, I want my finder at the model level for rspec testing.

If you’re on Rails 3 (as you presumably are, given the question’s tags) you should be using scope rather than named_scope and where rather than conditions. Additionally, you can’t use >= in a hash.

Your finished scope should look something like this:

scope :recent_snaps, lambda { |since_when| where("created_at >= ?", since_when) }
