Question

I have an object named Puzzle and I’m calling .map on it in order to isolate the ‘title’ values. I then use ‘puts’ in order to print them neatly but nothing is returned.

def puzzle_find
  title_array = self.puzzles.map { |s| s.title }
  puts title_array
end
#=> " "

If I don’t use ‘puts’ then I get the array like this:

def puzzle_find
  title_array = self.puzzles.map { |s| s.title }
end  

#=> ["title 1", "title 2", "title 3"]

I’m trying to make the output look like this in my view:

title 1
title 2
title 3

thanks

Answer 1

The collection of titles should be prepared in the controller (or exposed by the controller and retrieved in the model, or etc., as long as there’s a collection of titles at the end of it all):

def controller_method
  @puzzles = ... whatever ...
  @titles = @puzzles.collect(&:title)
end 

View:

<% @titles.each do |t| %>
  <%= t %><br/>
<% end %>

(Or wrap it up in a partial, or use a helper. Above assumes scrubbed of HTML badness.)
