Hi to everyboy.. I need your help in order to know if I get wrong..
I have this migration file:
class CreateSpecifications < ActiveRecord::Migration
def self.up
create_table :specifications do |t|
t.string :tolerancia
t.integer :umbral
t.timestamps
end
end
def self.down
drop_table :specifications
end
end
I put some data by mean of script/console
Specification.create(:umbral => 33, :tolerancia => 'alta')
Specification.create(:umbral => 23, :tolerancia => 'alta')
Specification.create(:umbral => 12, :tolerancia => 'baja')
Specification.create(:umbral => 33, :tolerancia => 'baja')
Then when I run the following statement
Specification.find(:all, :select => 'tolerancia, sum(umbral) as
total', :group => 'tolerancia')
I get the following:
[#<Specification tolerancia: "alta">, #<Specification tolerancia:
"baja">]
Where is my total field??? How could I get it???
Besides, whit the following statement:
>> Specification.find(:first, :select => 'now() as ahora')
=> #<Specification >
Where is my field 'ahora'?
Thanks in advanced by your help...
