我正在编写一个 ruby-on-rails 库模块:
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
当我调用 render_for_search 时出现错误
undefined method 'link_to'
我尝试直接要求 url_helper 但无法弄清楚出了什么问题。
尝试这个:
ActionController::Base.helpers.link_to
