I'm pretty sure that classify actually returns the constant (not just the string name of the constant), so you shouldn't need the eval.

Looking into it, classify returns a string, but the singularize is unnecessary. I'll update the snippet.

Maybe this one is easier to read (and to understand):

def model_for_table(table_name)
table_name.to_s.classify.constantize
end

I posted a more versatile version of this a while back, as well as the opposite method for turning a model into a string akin to the table name. See http://www.bigbold.com/snippets/posts/show/2135

Er, not 'versatile', but 'verbose'.
