Counting and grouping at the same time

Question

I have a Mail model with the following schema:

t.string   \"mail\"
t.integer  \"country\"
t.boolean  \"validated\"
t.datetime \"created_at\"
t.d         


        

Answer 1

Try:

Mail.count(:group => 'country', :conditions => ['validated = ?', 't'])

I'm not sure count accepts :limit though.

EDIT:

I think this is more readable:

Mail.count(:group => :country, :conditions => {:validated => true})
