ruby on rails 3-如何在控制器中使用breadcrumbs_on_rrails

Question

我尝试使用breadcrumbs_on_rrails，但每次都会出现错误：

syntax error, unexpected '(', expecting keyword_end add_breadcrumb "City", :doctors_city_sort_path(params[:city_id])

控制器内：

def sort_by_city
  @doctors = Doctor.where('city_id = ?', params[:city_id]).
    paginate(page: params[:page], :per_page =>10)
  add_breadcrumb "City", :doctors_city_sort_path(params[:city_id])
  render 'index'
end

在路线上。rb:

get '/doctors/city/:city_id', 
    to: 'doctors#sort_by_city', as: 'doctors_city_sort'

请帮助查找此任务的决策

Answer 1

您有一个冒号add_breadcrumb调用，请尝试以下操作：

def sort_by_city
  @doctors = Doctor.where('city_id = ?', params[:city_id]).
    paginate(page: params[:page], :per_page =>10)
  add_breadcrumb "City", doctors_city_sort_path(params[:city_id])
  render 'index'
end

Answer 2

我找到了决定！它看起来像：

 @city = City.find(params[:city_id])
 add_breadcrumb "#{@city.name}", "#{@city.id}"
