Question

I have a very simple Ruby question. Is there a way to refactor this:

<%= some_array.length if some_array.length > 1 %>

into something like

<%= some_array.length if self > 1 %>

where ‘self’ (for example) is references the initially calculated value – i.e. some_array.length?

Answer 1

I like to keep the main templates simple and pull logic into helpers. The erb can contain:

<%= display_length(some_array) %>

where the helper contains:

def display_length(array)
  array.length if array.length > 1
end

Of course, adjust the names to best represent your business logic.
