我正在尝试创建一个更新 2 个表的表单——commission_type 和 Commission_tier。

我创建了模型、控制器和表单，但是当我提交它时，我的commission_tier 表没有更新。只有我的commission_type 表更新。

有人可以看看我的代码并告诉我我做错了什么吗？我已经梳理了我的代码试图找到错误，但我找不到它。

我的模型

class CommissionType < ApplicationRecord
  has_many :commission_tiers
  accepts_nested_attributes_for :commission_tiers
end

class CommissionTier < ApplicationRecord
  belongs_to :commission_types, optional: true
end

我的控制器

class Admin::CommissionTypesController < Admin::BaseController


  def index
    @commission_types = CommissionType.all
  end

  def new
    @commission_type = CommissionType.new
    @commission_type.commission_tiers.build
  end

def create
    @commission_type = CommissionType.new(commission_type_params)
    if @commission_type.save
      redirect_to admin_commission_types_index_path
    else
      render "new"
    end
  private

  def commission_type_params
    params.require(:commission_type).permit(:name, :active, :allow_mass_update, :plan,
                                               commission_tiers_attributes: [:id, :increment_value, :rate, :commission_type_id])
  end
end

我的表格

<%= simple_form_for @commission_type, url: admin_commission_types_index_path, wrapper: :bootstrap2, :html => { :class => 'form-horizontal' } do |f| %>
      <fieldset>
        <legend>Properties</legend>
        <%= f.input :name, label: 'Commission Name' %>

        <%= f.input :active, as: :boolean, label: 'Active?', label_html: { class: 'padding-top' } %>
        <%= f.input :allow_mass_update, as: :boolean,  label: 'Allow mass update?', label_html: { class: 'padding-top' } %>
        <%= f.input :plan, input_html: {id: 'dropdown'},
                    label: 'Commission Type', 
                    collection: [ ['Select One..', 'select'], ['Flat', 'flat'], ['Flat +', 'flat_plus' ], ['Promotional', 'promotional'], ['Straight', 'straight'], ['Waterfall', 'waterfall'],  ['Sliding Scale', 'sliding_scale'] ],
                    selected: 'select'
                    %>
      </fieldset>
     
        
      <fieldset id="flat">
        <legend>Flat Commission</legend>
        <%= f.simple_fields_for :commission_tiers do |builder| %>
          <%= builder.input :rate %>
          <%= builder.input :increment_value %>
        <% end %>
      </fieldset>

我的表格正在显示和工作 html表单

更新

一些额外的细节

CommissionType column values = [:name, :active, :allow_mass_update, :plan]

CommissionTier column values = [:id, :increment_value, :rate, :commission_type_id]

另外，当我提交表单时，这是我的params示例

<ActionController::Parameters {"name"=>"asdf", "active"=>"1", "allow_mass_update"=>"1", "plan"=>"flat", "commission_tiers_attributes"=><ActionController::Parameters {"0"=><ActionController::Parameters {"rate"=>"45"} permitted: true>} permitted: true>} permitted: true>
