Ruby on rails 嵌套资源的Rails路由

在使用嵌套资源路由时，当尝试查看搜索结果时，我不断收到以下错误消息，如下所示。由于某些原因，我无法让rails使用以下路径和控制器中的

重定向到@search

调用显示搜索结果

路由。rb：

resources :users do
    resources :searches
end

NoMethodError in SearchesController#create

undefined method `search_url' for #<SearchesController:0x007fc68a881708>

      Extracted source (around line #19):
17 @search = current_user.searches.create(search_params)
18
19  redirect_to @search
20
21 end
22

以下是错误信息：

resources :users do
    resources :searches
end

NoMethodError in SearchesController#create

undefined method `search_url' for #<SearchesController:0x007fc68a881708>

      Extracted source (around line #19):
17 @search = current_user.searches.create(search_params)
18
19  redirect_to @search
20
21 end
22

搜索控制器中的NoMethodError#创建 未定义的方法“搜索url”# 提取的源（第19行附近）： 17@search=当前用户.search.create（搜索参数） 18 19将_重定向到@search 20 21完 22 搜索控制器：

class SearchesController < ApplicationController
  before_action :require_user

  def index
  end

  def new
    # @states = ["red","green","blue"]
    @states = State.all
    @cities = City.all
    @languages = Language.all
    @search = Search.new
  end

  def create
    @search = current_user.searches.create(search_params)
    redirect_to @search
    #Old Search
    #@search = Search.create(search_params)
  end

  def show
    #@search = Search.find(params[:id])
    #@search = @user.searches.find(params[:id])
    @search = current_user.searches.find_by(id: params[:id])
  end

  #Deleting searches, tied to the "delete link" on the view
  def destroy
    @search.destroy
    flash[:success] = "Micropost deleted"
    redirect_to request.referrer || @searches
  end

  private

  def search_params
    #:userid = @user.id
    params.require(:search).permit(:searchname, :city, :min_gpa, :max_gpa, :firstname, :state, :city, :age, :gender, :universityname, :language, :livingin, :workexperience, :monthsspentabroadLiving, :monthsspentabroadworking, :degree , :degreetype, :countryofdegree, :wantstoworkin, :hasworkexperiencein, :permissiontoworkin, :currentlyemployed, :referencesuponrequest, :worktype, :charitywork)
  end
end

 <%= bootstrap_form_for @search, url: user_searches_path(current_user), html: {class: "pure-form"} do |s| %>

          <%= s.hidden_field :userid, :value => current_user.id %>

          <div class="field">
            <%= s.text_field :searchname, label: "Search Name" %>
          </div>

class SearchesController

新搜索表单-查看：

class SearchesController < ApplicationController
  before_action :require_user

  def index
  end

  def new
    # @states = ["red","green","blue"]
    @states = State.all
    @cities = City.all
    @languages = Language.all
    @search = Search.new
  end

  def create
    @search = current_user.searches.create(search_params)
    redirect_to @search
    #Old Search
    #@search = Search.create(search_params)
  end

  def show
    #@search = Search.find(params[:id])
    #@search = @user.searches.find(params[:id])
    @search = current_user.searches.find_by(id: params[:id])
  end

  #Deleting searches, tied to the "delete link" on the view
  def destroy
    @search.destroy
    flash[:success] = "Micropost deleted"
    redirect_to request.referrer || @searches
  end

  private

  def search_params
    #:userid = @user.id
    params.require(:search).permit(:searchname, :city, :min_gpa, :max_gpa, :firstname, :state, :city, :age, :gender, :universityname, :language, :livingin, :workexperience, :monthsspentabroadLiving, :monthsspentabroadworking, :degree , :degreetype, :countryofdegree, :wantstoworkin, :hasworkexperiencein, :permissiontoworkin, :currentlyemployed, :referencesuponrequest, :worktype, :charitywork)
  end
end

 <%= bootstrap_form_for @search, url: user_searches_path(current_user), html: {class: "pure-form"} do |s| %>

          <%= s.hidden_field :userid, :value => current_user.id %>

          <div class="field">
            <%= s.text_field :searchname, label: "Search Name" %>
          </div>

当前用户id%>

如果您执行一个

bundle exec rake routes

，您将看到您有这个路由：

user_search GET    /users/:user_id/searches/:id(.:format)      searches#show

这是因为您的

搜索

资源嵌套在

用户

资源下。因此，您需要将

当前用户

和

@search

传递给

用户搜索路径

助手方法

因此，重定向到用户搜索页面的正确方法是：

redirect_to user_search_path(current_user, @search)
