How to return more than one value from a function?

Rails
1

Hi

In an action in admin_controller, I called a method in the model ci.rb
The code is shown below:

In controller:
can_delete = Ci.is_ci_class_in_use(ci_type, @ci_classes)

Then in model:

 class Ci < ActiveRecord::Base

   def self.is_ci_class_in_use(ci_type,ci_classes)
     @cis=self.find_all_by_citype(ci_type.to_s)
     for ci in @cis
       for ci_class in ci_classes
         if ci.content.ci_class.to_i == ci_class.id.to_i
           can_delete = 0
           ci_number = ci.ci_number
           break
         else
           can_delete = 1
         end
       break if can_delete==0
      end
      break if can_delete==0
     end
    return   # I have to return two variables can_delete and

ci_number here.
end
end

 How can I return the two variables can_delete and ci_number?
 Please help.

Thanks
Regards

Why dont you return it as an Array? - return [can_delete,ci_number]

Hi

Thank you for your help. I tried returning it as an array. Then I
printed it in the console to see how it is returned.

can_delete = Ci.is_ci_class_in_use(ci_type, @ci_classes)
puts "the value returned is: " +can_delete.to_s

It printed:
the value returned is: 0CI15

The value of can_delete = 0 and ci_number = CI15

How can I retrieve these values from the returned array?

Thanks

return as hash or array
return {:can_delete => 0, :ci_number => what_ever_the_number}

You can also just use more than one variable on the receiving end and
send each value back independently (not in an array).

var_1, var_2 = some_method

def some_method
return ‘hi’, ‘there’
end

Peace,
