嘿，我正在使用Rails 4 Ruby 2构建一个应用程序。
我最近嵌套了一个表单在我的Calls Show页面的一侧，我添加了Ping（更新）功能。
因为我已经完成了嵌套...我可以在show字段中看到Ping创建新Ping的按钮，但是我已经失去了一起创建新调用的能力。
我得到的错误是：
ActionController::UrlGenerationError in Calls#new
Showing /Users/TaurenLTD1/Desktop/TaurenLabs/PatrolProCAD/PatProCadApp/app/views/calls/_form.html.erb where line #459 raised:

我不知道我哪里出错了，因为我之前和之后都没有嵌套过去通过一些关于嵌套的教程我仍然卡住了。
非常感谢任何帮助！

我会尝试从命令行运行rake routes，看看routes.rb生成的路由是否符合您的错误。
发布运行rake routes的相关信息可能很有用。
编辑：
在第459行尝试new_call_ping_path，而不是new_call_ping_path(@call)。
编辑2：
试试new_call_ping_path(call_id: @call.id)。这里的问题是网址生成器期待call_id，因为在routes.rb中声明格式如下：new_call_ping GET /calls/:call_id/pings/new(.:format)。

如果更新呼叫控制器中的呼叫，则必须执行以下操作： -
模型Call.rb
has_many :pings
accepts_nested_attributes_for :pings
允许call_params方法中的嵌套属性，并在calls_contoller.rb中更改new和create方法，如： -
def new
@call = Call.new
@unit_2 = @call.unit_2
@unit_3 = @call.unit_3
@unit_4 = @call.unit_4
@pings = @call.pings.build
end
def create
@call = Call.new(call_params)
respond_to do |format|
if @call.save
format.html { redirect_to @call, notice: 'Call was successfully created.' }
format.json { render :show, status: :created, location: @call }
else
format.html { render :new }
format.json { render json: @call.errors, status: :unprocessable_entity }
end
end
private
def call_params
params.require(:call).permit(:call_time, :status, :primary_type, :secondary_type, :site, :address, :unit_1, :unit_2, :unit_3, :unit_4, :call_details, :unit_on_scene, :unit_clear, :call_num, :site_id, :user_id, :unit2_os, :unit2_cl, :unit3_os, :unit3_cl, :unit4_os, :unit4_cl,
pings_attributes: [:id, :priority, :msg, :received])
end
如果你想通过ping控制器为呼叫添加ping，那么你可以这样做： -
def new
@call = Call.find(params[:call_id])
@pings = @call.pings.build
end
def create
@call = Call.find(params[:call_id])
respond_to do |format|
if @call.update_attributes(call_params)
format.html { redirect_to @call, notice: 'Call update has been successfully added to call.' }
format.json { render :show, status: :created, location: @call }
else
format.html { render :new }
format.json { render json: @call.errors, status: :unprocessable_entity }
end
end
end
private
def call_params
params.require(:call).permit(pings_attributes: [:id, :priority, :msg, :received])
end
答案 2 :(得分：0)
所以我解决了这个小问题..这实际上是一个非常荒谬的问题..当我创建嵌套控制器时，我将控制器打开，当我将文件拖放到控制器下的调用文件夹中时..
发生了什么事虽然我指的是呼叫/ ping控制器，即使rake路线显示了相应的路线，rails还是看着原来的ping控制器..
一旦我删除了重复的控制器，所有都落到了位置并开始正常工作。
感谢大家努力解决这个问题！
