Rails 5 - 作为 Taggable On - 特定标签列表的不允许参数

Question

我正在尝试让行为在设置时可标记以与我的 Rails 5 应用程序一起使用。

我有一个名为 Randd::Field.rb 的模型，其中有一个名为 :title 的属性。我想将这些标题用作我的提案模型的标签。

我的 Proposal.rb 有：

class 提案 < 申请记录包括 Statesman::Adapters::ActiveRecordQueries

  acts_as_taggable
  acts_as_taggable_on :randd_maturities, :randd_fields, :randd_purposes, :randd_activities

我的提案 form.html.erb 有：

<%= f.collection_select :randd_field_list, Randd::Field.order(:title), :id, :title, {}, {multiple: true} %>

我的提案控制器将 randd_field_list 列入白名单：

  def proposal_params
      params.require(:proposal).permit(:title, :randd_maturities_list, :randd_field_list, :randd_purposes_list, :randd_activities_list)

当我保存所有这些并尝试向提案添加标签时，出现错误。服务器日志显示：

Unpermitted parameter: randd_field_list

这没有任何意义，因为当属性未在允许的参数中列入白名单时会出现问题 - 我已经做到了。

任何人都可以看到需要做什么才能通过提案表格保存标签吗？

我发现 gem 文档令人困惑，因为它显示：

Setup

class User < ActiveRecord::Base acts_as_taggable # Alias for acts_as_taggable_on :tags acts_as_taggable_on :skills, :interests end

class UsersController < ApplicationController def user_params params.require(:user).permit(:name, :tag_list) ## Rails 4 strong params usage end end

为什么允许的参数不包含 :skill_list 和 :interest_list，因为这些特定模型用作标签？我是否应该将 "tag_list" 添加到我的提案允许的参数中，即使可以添加的唯一标签来自我列出的特定模型中定义的标题：

acts_as_taggable_on :randd_maturities, :randd_fields, :randd_purposes, :randd_activities

服务器日志显示：

Unpermitted parameter: randd_field_list

Answer 1

您为 *_list 参数发送了一个数组。尝试在 permit 方法中为每个 _list 添加 []：

params.require(:proposal).permit(
  :title, 
  randd_maturities_list: [], 
  randd_field_list: [], 
  randd_purposes_list: [], 
  randd_activities_list: [])
