@lyfi2003 rails5.2 中 lock! 的机制有变化，导制以前正常的代码，时不时的出现（不是每次都出现），以什么办法兼容吗

RuntimeError (Locking a record with unpersisted changes is not supported. Use `save` to persist the changes, or `reload` to discard them explicitly.)

@jasl 嗯，我刚也试了，在 5.2 下正常，感谢

@jasl 我的 ruby 版本是 2.5.1 rails5.0.7.2

@jasl 用的是 role_core,和你 dummy 唯一不同的地方就是我没用 cancancan

def create
    @role = Role.new(role_params)

    if @role.save
      redirect_to roles_url, notice: "Role was successfully created."
    else
      render :new
    end
  end

# Only allow a trusted parameter "white list" through.
  private def role_params
    params.require(:role).permit(:name, permissions_attributes: {})
  end

@jasl 照着你的那个例子自己写的

@jasl 这样编辑权限的时候好像没生效

@jasl 这个地方参数要怎么设置，手动一个一个指定吗？

# Only allow a trusted parameter "white list" through.
  private def role_params
    params.require(:role).permit(:name, permissions_attributes: {})
  end

下单成功，等待签收
