Question

I’m trying to hook up a custom helper that has a default class ‘pjax’ but also retains an ability to add classes where need be.

Example:

link_to_pjax('pagename', page_path, :class => 'current')

So the helper would add the ‘pjax’ by default, and also the class ‘current’, or whatever is passed in.

def link_to_pjax(name, path, options = {:class => 'pjax'})
    link_to(name, path, options)
end

The syntax is freaking me out. Any advice would be much appreciated.

Answer 1

def link_to_pjax(name, path, options)
  options[:class] += ' pjax'
  link_to(name, path, options)
end

edit

After test, it’s much less elegant:

 def link_to_pjax(name, path, options = {})
   options[:class] ? options[:class] += ' pjax' : options[:class] = 'pjax'
   link_to(name, path, options)
 end

My first solution works but only if you have still specified a class.

The latest works in all cases:

• link_to_pjax ‘click me’, my_super_path, class: ‘ahah’, id: ‘hello’
• link_to_pjax ‘click me’, my_super_path
• etc

My bad…
