嵌套在导轨中的路由错误

我目前正在研究我的项目，但遇到一些挑战。我有一个项目模型，有评论对象嵌套到它我可以创建一个新的评论，但当我尝试编辑与项目对象关联的评论我在浏览器中得到这个奇怪的错误，显示我想编辑评论属于一个不存在的项目。其实当我检查网址时，项目的ID并不存在。例如，如果我想编辑属于ID为1的项目的注释，该错误消息指示我想编辑属于具有ID 2的项目的注释。我尝试了所有我知道但可以'没有找到问题的根源。这是我的意见控制器看起来像嵌套在导轨中的路由错误

    @projects = Project.all

在你的表演方法已经使用PARAMS [：编号]作为PROJECT_ID

@project = Project.find_by(:id => params[:id])

尝试将其更改为

@project = Project.find_by(:id => params[:project_id])
