我试图在完成表单后手动向控制器中的参数添加其他属性。参数似乎包裹在中，这似乎阻止了我更改参数。

控制器：

class ActualsController < SignedInController
...
 def update
   respond_to do |format|
   facesheet = actual_params[:facesheet]

   #trying to manually add attribute
   actual_params.merge(:file_name => 'ted.png')
   new_params = actual_params.except(:facesheet)

      if @actual.update(new_params)
        format.html { redirect_to action: 'show', id:@actual.id, notice: 'Actual was successfully updated.' }
        format.json { render :show, status: :ok, location: @actual }
      else
        format.html { render :edit }
        format.json { render json: @actual.errors, status: :unprocessable_entity }
      end

   end
 end
...
end

控制台中的“ new_params”
