Rails，我在创建和更新时总是遇到400错误的请求，找不到原因

我正在尝试为住宿模型创建/更新的表单，无论其中哪一个我都遇到400错误的请求。查看我的development.log，我可以看到

ActionController :: ParameterMissing（缺少参数或值为空：可容纳）：
app / controllers / accommodations_controller.rb：75：in accommodation_params' app/controllers/accommodations_controller.rb:12:increate'

如您在上方看到的，我的住宿参数在控制器中的第75行保持为空。我已经在下面的控制器中指出了这些行。我在这里找不到问题所在，因为我为区域模型使用了完全相同的代码，并且效果很好。这些模型也几乎相同。

我的更新表格：

<div class="modal-body">
        <%=form_for @accommodation, url: accommodations_update_path, remote: true, html: {class: "form-horizontal",:multipart => true} do |f|%>

        <fieldset class="content-group">
          <legend class="text-bold">Images</legend>
          <div class="form-group">
            <label class="col-lg-2 text-semibold">Current images: <span style="color:grey">Click to delete</span> </label>
            <div class="col-lg-10">
              <% @accommodation.accommodation_attachments.each do |a| %>
                <%unless a.image.blank?%>
                  <%= link_to delete_accommodation_attachment_path(a), :remote => true, :method => :delete,data: { confirm: "Are you sure you want to delete this image?"} do%>
                     <%= image_tag a.image_url(:thumb), class:"delete-image" %>                 
                  <% end %>
                <% end %>
              <% end %>
            </div>
          </div>
          <div class="form-group">
            <label class="col-lg-2 text-semibold">Add images:</label>
            <div class="col-lg-10">

            <%= f.fields_for :accommodation_attachments, @accommodation.accommodation_attachments.build do |aa| %>              
              <div class="field">
               <br>
               <%= aa.file_field :image, :multiple => true, name: "accommodation_attachments[image][]" %>
              </div>                          
            <% end %>
           </div>
         </div>

       </fieldset>                              
      <div class="form-group">

        <div class="col-md-2 col-md-offset-8">
          <input type="submit" class="btn btn-success" value="Submit" >
        </div>

      </div>

      <% end %>

    end

    def create
        #LINE 12 IS THE NEXT ONE
          @accommodation = Accommodation.new(accommodation_params)

        if @accommodation.save
            params[:accommodation_attachments]['image'].each do |a|

    def edit        

    end

    def update

        if @accommodation.update(accommodation_params)
            params[:accommodation_attachments]['image'].each do |a|
                @accommodation_attachment = @accommodation.accommodation_attachments.create!(:image => a, :accommodation_id => @accommodation.id)

        respond_to do |format|
            format.js
        end
    end

    def delete_accommodation
        @accommodation = Accommodation.find(params[:id])
        @accommodation.destroy

        respond_to do |format|
            format.js
        end
    end

    def find_accommodation_by_id
        accommodation = Accommodation.find(params[:id])
        render json: accommodation
    end

    protected

    def news_list
        respond_to do |format|
            format.js
        end
    end



    private

    def accommodation_params
      #LINE 75 IS THE NEXT ONE
     params.require(:accommodation).permit(:id, accommodation_attachments_attributes: [:id, :accommodation_id, :image])
   end

    def set_accommodation
        @accommodation = Accommodation.find_by_id(params[:id])
        @languages = Language.all
        @accommodation_attachments = @accommodation.accommodation_attachments.all
        @accommodations = Accommodation.all
    end

    def set_accommodations
        @accommodations = Accommodation.all
        @article = Article.all
    end


end

我考虑住宿的路线：

  get '/accommodations/new', to: 'accommodations#new', :as => 'accommodations_new'
  post '/accommodations/create', to: 'accommodations#create', :as => 'accommodations_create'
  get '/accommodations/:id/destroy', to: 'accommodations#destroy', :as => 'accommodations_destroy'
  delete 'delete_accommodation/:id', controller: 'accommodations', action: 'delete_accommodation'
  get '/accommodations/:id/edit', to: 'accommodations#edit', :as => 'accommodations_edit'
  patch '/accommodations/:id/update', to: 'accommodations#update', :as => 'accommodations_update'
