Hey guys,

I am working on a class project and I have two scaffolded models,  
articles and sub\_articles. I have the relationships set to articles  
having many sub\_articles and sub\_articles belonging to articles, which  
is also stated in the routes file.

I am trying to display a link to each sub article when viewing a  
specific article, as it stands now I can display the link with the sub  
article title but it links back to the same article.

here are some code samples:

this is my sub article partial that shows the links,

- \<%= link\_to (sub\_article.title), h(sub\_article.id) %\>

how do i add the prefix sub\_articles/ to the id link?

also when I go to a url like /sub\_articles/1 I get an unknown action  
error, but I have a show.html.erb file

your help would be greatly appreciated, thank you all.

link\_to(sub\_article.title, sub\_article)

Rails knows the rest.

</div>

but that ends up with a link that looks like this in the browser

[http://localhost:3000/articles/1#\<SubArticle:0x597e8c0\>](http://localhost:3000/articles/1#%3CSubArticle:0x597e8c0%3E)

do i need to add something else where to make this work?
