ActionController::UrlGenerationError 在搜索中#search

Question

我已经安装了 ElasticSearch，但我用这个无法搜索：

<%= link_to genre_linker.genre, movie_genre_linker_path(@movie, genre_linker) %>

但是当我使用这个时结果显示正确:

<%= link_to genre_linker.genre %>

所以，由于搜索有效，我认为问题出在我的语法中。

这是我的路线：

movie_genre_linker GET    /movies/:movie_id/genre_linkers/:id(.:format)         genre_linkers#show

这是错误信息：

我还是个菜鸟，所以非常感谢任何指导。

Answer 1

这有效： <%= link_to genre_linker.genre, movie_path(genre_linker.movie.id) %>
