Question

I’m creating a site using a small Ruby framework, Sinatra, but I would like to be able to do something like what the Rails link_to_unless_current method does, without using Rails.

Now I have my own link_to method, which works the same as the Rails one, more or less, so how would I go about doing the _unless_current part?

Answer 1

Seeing as how you mentioned your link_to method is similar to the Rails one, give this a try:

def link_to_unless_current(text, location)
  if request.path_info == location
    text
  else
    link_to text, location
  end
end

I gave this a quick test and worked perfectly for me, however if your link_to method takes more parameters, it’s pretty simple to add more, just add them to the _unless_current(text, location, param1, param2, etc) and the link_to text, location, param1, param2, etc parts of the code.
