Use Angular variable in Rails link_to

Question

I'm using Angularjs in parts of my Rails app, which works great. But I'm wondering how to use an Angular value inside a link_to.

Here is my pseudo code:

%table          
  %tr{"ng-repeat" => "book in books"}
    %td
      {{book.title}}
    %td= link_to "Show", book_url({{book.id}})

This gives me an error:

syntax error, unexpected '}', expecting tASSOC

This could also have to do with HAML causing the error, but how can I send the ID in the link_to?

Instead of a "link_to", I can of course use a normal link: %a{href: 'books/{{book.id}}'} 'Show' — John

This worked for me:

<li ng-repeat="deal in deals">
    <%= link_to 'show,'#','ng-href' => "#{deals_path()}/{{deal.id}}" %>
</li>

Wont anything after the # be treated as a comment and therefore not work?

@Linus: no, the # is inside a string.

Oh yes you're absolutely right, it was just Atom not being able to display the syntax correctly.

It work fine:

= link_to 'Show', URI::unescape(books_path('{{book._id}}'))
