I'm writing a ruby-on-rails library module:
module Facets
class Facet
attr_accessor :name, :display_name, :category, :group, :special
...
URI = {:controller => 'wiki', :action => 'plants'}
SEARCH = {:status => WikiLink::CURRENT}
#Parameters is an hash of {:field => "1"} values
def render_for_search(parameters)
result = link_to(display_name, URI.merge(parameters).merge({name => "1"}))
count = WikiPlant.count(:conditions => (SEARCH.merge(parameters.merge({name => "1"}))))
result << "(#{count})"
end
end
...
end
when I call render_for_search I get the error
undefined method 'link_to'
I've tried requiring url_helper directly but can't figure out what's going wrong.
