Rails - return html black from model

Question

I have a method in my model which is called in a modal like this:

<div class="col-sm-9"><%= @notification.notifier_context %></div>

In this method, I want to return some HTML like this, which has a rails helper path in it.

context = "<td><%= link_to('link', account_item_path(@item.account, @item))%></td>".html_safe

But its just out-putting the string as is. How can I get it evaluated to HTML proper?

Thanks

Try:

"<td>#{link_to('link', Rails.application.routes.url_helpers.account_item_path(@item.account, @item))}</td>".html_safe

String is not erb template so you can't use <%= %> syntax. Also it's great idea to use helpers (with content_tag) or partials for that. Also if you need to use routes inside model class, read following answer.

This answer works great - hopefully it is a suitable way of achieving this! – user3437721 Sep 07 '15 at 11:16
@user3437721 The best way will be to use separate partial for that. In general model is not used for displaying views. – tiktak Sep 07 '15 at 11:20
it is a _form.html.erb partial currently, which calls a method in the model – user3437721 Sep 07 '15 at 11:24
so you can create another partial, pass a @notification there as local variable and render what you want (see doc about partials for examples). – tiktak Sep 07 '15 at 11:27
Yes, now it will work.. First answer was wrong. But this is not a best approach. – Arup Rakshit Sep 07 '15 at 11:29
