Question

I would like to set a before filter in a rails app as follows:

before_filter :set_instance_variables, :unless => :active_pages?

def active_pages?
  params[:controller] == "admin/*"
end

where I would like it to have the * represent any word so that the method is checking against any of the controllers that start with ‘admin/’. I thought the asterisk might be a wild card and work, but it doesn’t seem to be working. How can I accomplish this?

Answer 1

def active_pages?
  %r{^admin/.*} =~ params[:controller]
end

It uses =~ to match a String to a regular expression, and %r{} for the regular expression because your pattern contains a / (the // notation would be harder to read).
