我在单一资源 ( ) 中有一个嵌入式资源，并且在使用助手/profile/workout时遇到了一些问题。form_for

我已经定义了以下帮助程序，因为profile它只是基于current_user（只是重定向到正确的 url）：

def workout_path(*args)
    profile_workout_path(*args)
end

我有以下模型：

class Workout
  include Mongoid::Document
  include Mongoid::Timestamps

  field :name, type: String

  embedded_in :user
  embeds_many :movements
  accepts_nested_attributes_for :movements
end

控制器：

def new
  @workout = current_user.workouts.build
  @workout.movements.build
end

路线：

ComposerDelete::Application.routes.draw do
  authenticated :user do
    root :to => 'home#index'
  end

  root :to => "home#index"
  devise_for :users
  resources :users do
  end

  resource :profile do
    resources :workouts
  end
end

和形式

= form_for @workout do |f|
  %fieldset
    = f.label :name
    = f.text_field :name
    = f.fields_for :movements do |builder|
      = render "movement_fields", f: builder
    = link_to_add_fields "Add Movement", f, :movements
    = f.submit "Create"

当我访问 url:http://localhost:3500/profile/workouts/50b99b70f0f800cd53000002/edit时，表单具有以下标题：

<form accept-charset="UTF-8" action="/profile/workouts/50b99b70f0f800cd53000002" class="edit_workout" id="edit_workout_50b99b70f0f800cd53000002" method="post">

它得到了正确的 id ( edit_<model>_<id>)，但错误的方法 ( post, 应该是put)，而且，提交按钮说Create而不是Update. 该表格可以正常工作，并更新锻炼。

耙路线：

                    root        /                                    home#index

该方法将始终是POST，而不是PUT- 您的浏览器本身不支持PUT，因此 Rails 通过在表单中​​使用隐藏的表单字段来解决这个问题_method=PUT。有关这方面的一些文档，请参见此处。

另外，您自己的代码说= f.submit "Create"，所以难怪按钮说“创建”。
