Html inside of erb

Rails
1

Looking to embed the html ‘right guillemet’ (») inside of a
link_to reference in my view code…

<%= (role.rights.sort{|a, b| [a.controller, a.action] <=> [b.controller, b.action]}.collect{|rights| [link_to (rights.controller + " » " +
rights.action, :controller => “rights”, :action => “edit”, :id =>
rights.id)]}).join(“
”).html_safe -%>

which results in…

groups &raquo; add_member
groups &raquo; create
groups &raquo; delete_member
groups &raquo; destroy

which is not what I want obviously.

(and yes, I will probably just move this to a helper once I get it
working)

Is it possible to embed HTML code inside the ‘link_to’ ?

One way is to use “#{rights.controller} » #{rights.action}”.html_safe

I understand the process of using the #{} but that is still in the
middle of ‘link_to’ rails_tag helper and it seems that is the problem I
am having.

The problem is that the “inner” string is not marked as html_safe. In
your
link_to tag, this string is not considered html_safe:

link_to(*rights.controller + " &raquo; " + rights.action*,

:controller
=> “rights”, :action => “edit”, :id => rights.id)

Colin’s suggestion, which is the solution, is to mark the inner string
as
html_safe. The easiest way to do this is to use the #{} notation instead
of
string concatenation:

link_to(*"#{rights.controller} &raquo; #{rights.action}".html_safe*,

:controller => “rights”, :action => “edit”, :id => rights.id)

I see said the blind man

and thanks Colin for the solution which was not apparent to me and I did
have to clean up the syntax errors but it works.

Thanks
