Question

I’m stuck trying to get this helper to work properly. This is what I have but it assuredly does not work.

def registration_link step, step_number
  path = registration_path step
  classes = []
  classes << 'current' if current_step?(step)
  # how do I add the following line to appear before the link ?
  step_icon = "<span class='step_number'>#{step_number}</span>"
  link_to step_icon + t("registration.menu.#{step}"), path, :class => classes.join(' ')
end

I am trying to get step_icon to appear within the link_to and before the word generated by t("registration.menu.#{step}")

It seems I can sometimes get in there, but the tags <> are sanitized as well..

Any ideas?

Answer 1

link_to can accept a block to link to, normally like so:

link_to @account do
  image_tag @account.image.url
end

So you could (probably needs refactoring):

link_to path, :class => classes.join(' ') do
  "<span class='step_number'>#{step_number}</span>" + t("registration.menu.#{step}")
end

to render your strings as html, rather than escaped strings, you add .html_safe after.

Alternatively, you could create a tag like so

content_tag(:span, step_number, :class=>"step_number")
