Question

我正在寻找带有不同图库链接的绘制课程，每个课程都可以为用户提供上传工作。

我有一个名为＆＃34; lesson＆＃34;的控制器，模型和视图。链接的图库是＆＃34; illst_repot＆＃34; 我已将illust_repot与引用相关联。课程：参考和用户：参考

我在索引页面上没有问题，但我在新页面上遇到了问题未定义的方法`illust_reports_path＆＃39; 本地主机：3000 /经验/ 1 / illust_reports /新

这是我的路线

该模型已链接。我是rails的初学者，我在google上搜索了很长时间，然后堆叠，并在写完这条消息之前做了很多测试。问题出在哪儿？非常感谢你的时间。

Answer 1

lesson_illust_reports_path是否有效？

由于您的illust_report资源在lessons资源中已命名空间，因此您必须添加lesson。

Answer 2

未定义的方法`illust_reports_path'

您拥有 嵌套资源 。所以form_for应该如下所示

<%= form_for [@lesson, @illust_report] do |f| %>

并更改illust_reports_controller的{{1}}方法，如下所示

new

未定义的方法＆＃39; _path＆＃39;有参考
