Question

我一直在使用acts_as_commentable_with_threading gem，我无法获得保存的评论。

我的控制器：

 class CommentsController < ApplicationController

  def create
    @comment_hash = params[:comment]
    @obj = @comment_hash[:commentable_type].constantize.find(@comment_hash[:commentable_id])
    # Not implemented: check to see whether the user has permission to create a comment on this object
    @comment = Comment.build_from(@obj, current_user, @comment_hash[:body])

    if @comment.save
      flash[:notice] = "New comment saved!!!!!"
      redirect_to status_path(@obj)
      #redirect_to profiles_path(current_user)
    else
      flash[:alert] = "didn't save"
      redirect_to status_path(@obj)
    end
  end

private
# Never trust parameters from the scary internet, only allow the white list through.
def comment_params
  params.require(:comment,:commentable_id,:commentable_type, :user_id, :body)
end
end

当我检查开发日志时，我可以看到散列中的值都已填充，我可以看到事务开始保存，但会立即回滚。

Rails 4中的acts_as_commentable_with_threading将无法保存
