Ruby not iterating through an array that has one element

Question

Here is my loop

 subscriptions.each do |s|
     if s.is_active? && s.is_current?
        #do some stuff
     end
  end

subscriptions is an array that has one element. However it does not hit the if statement inside the loop.

When I step through it using rdebug I get this

(rdb:1748) p subscriptions.count
1

I am on ruby version 1.8.7

Am I missing something?

Thank you in advance for your help.

What about subscriptions.length? How are you sure that it's never stepping into the block? — Chris Heald

Put here the content of subscriptions by printing the "puts subscriptions.inspect". — megas

puts subscriptions.select{ |s| s.is_active? && s.is_current? }.length — Kyle

@ChrisHeald subscriptions.length returns 1 also. I know that it is not going into the block because I am using ruby-debug to step through the code. I see it skip the block and go on to some code that is past this loop. — kjennings.dev

@kjennings.dev You're correct. It basically filters the array to only the elements that met your conditions. — Kyle

Check if it works?

subscriptions.each { |s| puts s }

If above code prints your elements, then there is some issue with your condition i.e. below code is not proper:

if s.is_active? && s.is_current?
  #do some stuff
end

The problem ended up being Case sensitivity on some data in the DB. All is good now. It is peculiar that it seemed to have skipped the block, but I am sure it is my own ignorance of how ruby-debug works. I am after all relatively new to ruby/rails development. Thanks all!

Did you use next rather than step? next will not descend into functions, whereas step will. A block is basically an anonymous function.

I was using next. Amazing help!
