Apologize, a mistake of copy and paste..

This is the output..

Specification.find(:all, :select => ‘tolerancia, sum(umbral) as total’, :group => ‘tolerancia’)
=> [#<specification tolerancia:>, #<specification tolerancia:>]

Where is my total field??

Hi to everyboy.. I need your help in order to know if I get wrong..

I’m using rails 2.2.2 with MySQL 5.0

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:>, #<specification tolerancia:>]

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’?

I have ran this situation on Heroku.com with the same sadly results..

Thanks in advanced by your help…
