Documents that ActiveRecord's find by id uses to_i to coerce its argu…
…ments to integers
Just a couple of details: First the coercion is done only if the type of the primary key is integer. Second, if you don't mind, since we need to revise that previous one, instead of #to_i you would write to_i without hash and in fixed-width font (between plus signs).
mention that coercion only happens when the primary key is an integer…

Fantastic, thanks very much :).
