Question

我收到以下错误：

undefined method `recommendations_path' for  #<#<Class:0x0078>>

我有推荐模型

class Recommendation < ActiveRecord::Base
    belongs_to :user
    belongs_to :recommended_user, class_name: "User", foreign_key: :recommended_user_id
end

我有用户模型

class User < ActiveRecord::Base
   has_many :recommendations
   ................
end

在推荐控制器中

def new
    @recommendation = current_user.recommendations.new
end

在new.html.erb

<%= form_for @recommendation do |f| %>
    <%= f.text_field :relationship %>
    <%= f.text_field :comment %>
    <%= f.submit %>
<% end %>

我的路线，我认为问题在于：

  devise_for :users
  resources :users, only: [:show] do
    collection do
      get :customer_signup
      get :employee_signup
    end
    member do
      get :choose_role
      get :become_a_customer
      get :become_a_employee
    end
  end

  resources :users do
    resources :recommendations
  end

实际上，当表单试图识别@recommendation的路径时。

根据您的routes.rb，您的表单必须是：

<%= form_for [:user, @recommendation] do |f| %>

NoMethodError包含嵌套资源的用户路径
