Ruby on rails Rails在模型中分配id

ruby-on-rails

Ruby on rails Rails在模型中分配id,ruby-on-rails,Ruby On Rails,我想为注册分配事件选项id。通过将以下内容添加到表单中，我可以在视图中轻松完成此操作： <%= f.text_field :event_option_id, value: @event_option.id %> #app/controllers/registrations_controller.rb class RegistrationsController < ApplicationController def create @order

最简单的修复方法是将其添加到表单中：

最简单的修复方法是将其添加到表单中：

<%= form_for(@registration, remote: true) do |f| %>
  <%= hidden_field_tag :id, your_event_option_id %>
  ### your other stuffs


###你的其他东西

该错误明确指出，Rails在没有

id的情况下无法找到事件选项
：
def create
   @event_option = EventOption.find params[:id] #-> :id is not passed to create action

要修复它，只需使用作为表单一部分提交的参数
：
<%= f.text_field :event_option_id, value: @event_option.id  %>

#app/controllers/registrations_controller.rb
class RegistrationsController < ApplicationController
   def create
      @order        = current_order
      @registration = @order.registrations.new registration_params
      @registration.save
   end

   private

   def registration_params
      params.require(:registration).permit(:event_option_id, :other, :params)
   end
end

这将设置事件选项\u id
作为顶级参数散列的一部分，该散列将作为参数[：事件选项\u id]
传递给控制器（正如您已经拥有的）：
该错误明确指出，Rails在没有id
的情况下无法找到EventOption
：
def create
   @event_option = EventOption.find params[:id] #-> :id is not passed to create action

要修复它，只需使用作为表单一部分提交的参数
：
<%= f.text_field :event_option_id, value: @event_option.id  %>

#app/controllers/registrations_controller.rb
class RegistrationsController < ApplicationController
   def create
      @order        = current_order
      @registration = @order.registrations.new registration_params
      @registration.save
   end

   private

   def registration_params
      params.require(:registration).permit(:event_option_id, :other, :params)
   end

你能发布更多的日志吗？你要走哪条路线？注册是事件选项的子项吗？Post routes，更多日志（包括参数），在视图中查看表单将非常棒。我已使用日志和路由更新Post。注册是事件选项的子项，但我不嵌套路由。嵌套路由，这样您就可以获得事件选项\u id
，如果您不想通过视图发送。您知道为什么我可以通过event_选项的价格设置注册的价格，但不能对id执行相同的操作吗？您是否在参数中发送价格？它不在日志中扫描你发布更多日志了吗？你要走哪条路线？注册是事件选项的子项吗？Post routes，更多日志（包括参数），在视图中查看表单将非常棒。我已使用日志和路由更新Post。注册是事件选项的子项，但我不嵌套路由。嵌套路由，这样您就可以获得事件选项\u id
