Using link_to in a class in a Rails helper
Try using this:
self.class.helpers.link_toBecause link_to is not defined in your current scope.
The above will work for a controller, but I'm guessing it will work inside another helper as well. If not then try:
include ActionView::Helpers::UrlHelperAt the top of your helper.
This is because within the Class Facet you don't have access to the template binding.In order to call the render_for_search method you probably do something like
<%= Facet.new.render_for_search %>Just override your initialize method to take the current context as argument.The same applies to the params hash.
class Facet def initialize(context) @context = context end def render_for_search @context.link_to("Value", @context.params) endendThen call
<%= Facet.new(self).render_for_search %>Otherwise, define the render_for_search method directly within the MyHelper module and don't wrap it into a class.
