Rails嵌套表单无法保存或在更新时无法验证

Question

I have the following controller:

class Admin::ArticleChangeRequestsController < Admin::ApplicationController
  before_action :set_order, only: :index
  before_action :set_article_change_request, only: [:edit, :delete]
  helper SortClassHelper

  protected
  def set_order
    if params[:column].present?
      @column = params[:column]
    else
      @column = 'created_at'
    end

    if params[:sort].present?
      @sort = params[:sort]
    else
      @sort = 'desc'
    end

    @order = @column.to_s + ' ' + @sort.to_s
  end

  def set_article_change_request
    @article_change_request = ArticleChangeRequest.find(params[:id])
  end

  def article_change_request_params
    params[:article_change_request].permit(:title, :change, :article)
  end

  public
  def index
    @article_change_requests = ArticleChangeRequest.order(@order).page params[:page]
  end

  def edit
    if request.patch?
      if @article_change_request.update(article_change_request_params)
        redirect_to :admin_article_change_requests, :flash => { success: t(:article_change_request_updated) }
      end
    end
  end

  def delete
    if request.post?
      if @article_change_request.delete
        flash[:success] = t(:article_change_request_deleted)

        render :json => { :success => true }
      else
        render :json => { :success => false }
      end
    end
  end
end

and have added:

accepts_nested_attributes_for :article

in my ArticleChangeRequest model. However whenever I hit Update it does not validate or save the article. Here is my Form:

<%= form_for @article_change_request, { :url => :admin_article_change_request_edit } do |f| %>
  <%= render partial: 'form', locals: { f: f }  %>
  <div>
    <%= f.submit t(:update), class: 'submit' %>

<% end %>

Can anyone tell me why its not validating or updating?

Answer 1

params[:article_change_request].permit(:title, :change,
:article_attributes => {:category_id, :title, :slug, :article_type})
