ruby-on-rails - 表单数据未通过 POST 以参数形式发送

Question

当我提交表单时，数据不会在帖子中发送并通过参数设置。我一生都无法弄清楚为什么。该表单位于计划/显示操作中，因此您会看到我在那里设置 @action 变量。它是通过JS发送的。

routes.rb

resources :plans do 
    resources :actions
end

action.rb

belongs_to :plan

计划.rb

has_many :actions

plans_controller.rb

def show
    @plan = current_user.plans.includes(:actions).find(params[:id])
    @action = Action.new

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @plan }
    end
end

actions_controller.rb

before_filter :get_plan    

def create
    @action = @plan.actions.new(params[:action])
    @action.user_id = current_user.id
    @action.save
end

private

def get_plan
    @plan = current_user.plans.find(params[:plan_id])
end

在views/actions文件夹中创建.js.erb

$('div#actions').prepend("<%= escape_javascript(render @action) %>");
$('div#<%= dom_id(@action) %>').effect('highlight');

_form.html.erb部分

<%= form_for ([@plan, @action]), remote: true do |f| %>
  <%= f.text_field :desc %>
  <%= f.number_field :days %>
  <%= f.submit %>
<% end %>

通过 POST 发送的参数(缺少操作哈希 - 为什么？)

Started POST "/plans/1/actions"
Parameters: {"utf8"=>"✓", "authenticity_token"=>"**removed**", "commit"=>"Create Action", "plan_id"=>"1"}

数据库架构

create_table "plans", :force => true do |t|
  t.string   "name"
  t.integer  "user_id"
  t.datetime "created_at", :null => false
  t.datetime "updated_at", :null => false
end

create_table "actions", :force => true do |t|
    t.string   "desc"
    t.integer  "plan_id"
    t.integer  "days"
    t.datetime "created_at", :null => false
    t.datetime "updated_at", :null => false
end

操作是保留字。如果您将其称为其他任何名称( Controller 除外，这也是保留的)，那么它将起作用。

http://guides.rubyonrails.org/action_controller_overview.html#routing-parameters

The params hash will always contain the :controller and :action keys, but you should use the methods controller_name and action_name instead to access these values.
