嵌套参数不包括<name>_attributes in Rails 7 提交嵌套属性时

Nested parameter does not include <name>_attributes in Rails 7 when submitting nested attributes

我正面临这个问题,经过深入研究,我似乎找不到解决方案。

我试图在嵌套表单上创建一个用户和他的 meet_infos,但在参数中,我总是以“meet_infos”而不是“meet_infos”结尾_属性":

Unpermitted parameters: :page_id, :meets_infos. Context: { controller: Users::MeetInfosController, action: create, request: #<ActionDispatch::Request:0x00007f224cc73128>, params: {"authenticity_token"=>"[FILTERED]", "user"=>{"page_id"=>"1", "last_name"=>"nxgfbngh", "first_name"=>"n hgn cgn", "phone"=>"nfcntrsbgxd", "email"=>"hbfdhnbytdgbn", "meets_infos"=>{"page_id"=>"1", "reason"=>"dfgnhgdn", "datetime(1i)"=>"2022", "datetime(2i)"=>"4", "datetime(3i)"=>"26", "datetime(4i)"=>"11", "datetime(5i)"=>"17"}}, "commit"=>"Save User", "controller"=>"users/meet_infos", "action"=>"create", "page_id"=>"1"} }

我的表格:

<%= simple_form_for :user do |f| %>
 <%= f.error_notification %>

  <%= f.input :page_id, as: :hidden, input_html: { value: @page.id } %>

  <%= f.input :last_name %>
  <%= f.input :first_name %>
  <%= f.input :phone, :as => :tel %>
  <%= f.input :email, :as => :email %>

  <%= f.simple_fields_for :meet_infos do |mf| %>
    <%= mf.input :page_id, as: :hidden, input_html: { value: @page.id } %>
    <%= mf.input :reason, :as => :text %>
    <%= mf.input :datetime, :as => :datetime %>
  <% end %>


  <%= f.submit %>
<% end %>

我的控制器:

class Users::MeetInfosController < ApplicationController
  skip_before_action :authenticate_admin!
  before_action :set_page, only: %i[index create destroy]

  def index; end

  def create
    @user = User.new(user_params)
    if @user.save
      redirect_to page_users_meet_infos_path
      flash[:success] = 'Rdv pris'
    else
      render :index
    end
  end

  private

  def user_params
    params.require(:user).permit(:id, :last_name, :first_name, :phone, :email, { meet_infos_attributes: [:id, :reason, :datetime, :_destroy] }).merge(page_id: @page.id)
  end

  def set_page
    @page = Page.find(params[:page_id])
  end
end

用户模型:

class User < ApplicationRecord
  belongs_to :page
  has_many :meet_infos, dependent: :destroy
  accepts_nested_attributes_for :meet_infos

  validates_presence_of :page_id
  validates :last_name, presence: true
  validates :first_name, presence: true
  validates :email, presence: true, uniqueness: true
  validates :phone, presence: true, uniqueness: true
end

MeetInfo 模型:

class MeetInfo < ApplicationRecord
  belongs_to :page
  belongs_to :user

  validates_presence_of :user
  validates_presence_of :page_id
  validates :reason, presence: true, uniqueness: true
  validates :datetime, presence: true, uniqueness: true
end

你有一个偷偷摸摸的 nil 错误。使用:

<%= simple_form_for @user do |f| %>

用一个符号调用 form_forsimple_form_for 并让它解析一个实例变量是一个愚蠢的遗留特性,已经被贬低了很长时间,我想是时候砍掉它了.

举个简单的例子:

<%= simple_form_for(@country) do |form| %>
  <% debugger form.object %>
  <%= form.input :name %>
  <fieldset>
    <legend>Cities</legend>
    <%= form.simple_fields_for :cities do |cities| %>
        <%= cities.input :name %>
    <% end %>
  </fieldset>
<% end %>

这会将您传递给 simple_form_for 的模型生成给调试器。如果将其更改为符号 simple_form_for(:country) ,您将得到 nil 而不是该符号似乎仅用作 form_with 的范围参数-并且由于没有模型 fields_for 只是使用符号 :meet_infos 而不是调用对象上的方法。

可以说 simple_form_for 应该提出错误并警告该行为是贬低的。
