Question

我正在尝试使用此帖子在帖子标题中创建链接以打开新页面。我尝试<%= link_to post.title, posts_path(path) %>，但收到错误

undefined local variable or method `posts_path' for #<#<Class:0x007fbf134f2b88>:0x007fbf13c17d78>

我做错了什么？

Answer 1

如果您只是想参加演出动作，那就足够写

了

<%= link_to post.title, post %>

与

相同

<%= link_to post.title, post_path(post) %>

查看文档：{{3}}

Answer 2

您正在尝试链接到单个帖子，但使用路径助手的复数形式，它不接受对象。使用post_path：

<%= link_to post.title, post_path(path) %>

复数形式是列出该网址的所有资源。单数形式用于显示ONE资源。

有关详细信息，请参阅rails routing上的本指南

Answer 3

我只需将此链接添加到我的节目页

<%= link_to 'Write a Review', new_comic_review_review_path(@comic_review)%>

链接到rails中的特定页面
