Search＃search中的ActionController :: UrlGenerationError

Question

I have installed ElasticSearch and I am unable to search when I use this:

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

but the results are correctly displayed when I use this:

<%= link_to genre_linker.genre %>

So, since the search works, I am thinking the problem is in my syntax.

this is my route:

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

this is the error message:

I am still sort of a noob, so any guidance will be greatly appreciated.
