i'm pretty new to RoR and the MVC style of programming in general. i
have one page  with a list of applications that several users can
access. in my view, i have a conditional that decides whether the
checkbox is checked or unchecked. being new to this, i just did it the
only way i could think of and want to see if there's a better way of
accomplishing it.

<%
selected_app = @user.apps.detect{ |app| app.id == app_line.id }
if selected_app
	is_checked = 'checked'
else
	is_checked = nil
end
-%>
<tr>
	<td><%= app_line.name %></td>
	<td><%= check_box 'add_app', app_line.id, { :checked => is_checked },
'yes', 'no' %></td>
</tr>
