Rails - how to move view logic into a helper when iterating through an array of objects

Question

So in my view, I am displaying the prices for Shirts, which belong to a Products category. In my view, I am currently looking through an array of shirts like so:

<% @shirts.get_shirts("red", "small").each do |shirt| %>
  <%= shirt.price ">
<% end %>

This works just like I want, displaying only the prices for shirts that are red and small.

However, when I try to move this logic into the corresponding helper, it displays the full object data instead of just the prices. My helper code is below:

def show_prices(color, size)
@shirts.get_shirts(color, size).each do |shirt|
  shirt.price
end
end

and I calling it in the view like so:

<%= show_prices("red","small") %>

What am I doing wrong in the helper? It seems like it should just do the same thing but it is not.

Result of each method is collection. Probably you want next helper method

def show_prices(color, size)
  @shirts.get_shirts(color, size).map(&:price).join
end
