Question

I’ve passed a field from my database, into my controller, so @download has a value of /link1, /link2, link3 I need to display all three links in my view. I’ve tried the following code:

%ul.pdf
  - ["#{@download}"]. each do|li|
    %li= link_to "title", "#{ li }"

but this just shows one hyperlink with the value of all three links in one. Is there any way i can get it to split at each comma or something?

Answer 1

Yes, you can split at the comma (this accounts for whitespace following the comma too).

@download.split(/,\s+/)

or, as a whole

%ul.pdf
  - @download.split(/,\s+/).each do|li|
    %li= link_to "title", "#{ li }"

though you might consider doing the split in the controller on @download depending on the context.
