Question

I m using vhochstein s fork of active_scaffold, which runs quite nicely on rails 3, except for a few small bugs - http://github.com/vhochstein/active_scaffold.

In rails 2.3, the following code disables a link:

return "<a class= disabled >#{text}</a>" unless authorized

But in Rails 3, it causes the escaped html tags to be printed out instead as in the following photo:

How can I make the content of this return statement render the way it should in rails 3?

The code above, is from the list_column_helpers.rb file in vendor/plugins/active_scaffold/helpers/

UPDATE:

Floatless fixed this by suggesting to add .html_safe to the code.

I have since found that the folowing change also needs to be made as there s more than one bit of code that is respondible for disabling action links in active_Scaffold:

In /plugins/active_scaffold/frontends/default/views/_list_actions.html.erb change:

<%= record.authorized_for?(:crud_type => etc etc etc -%>

By making it use "raw"

i.e. 

<%= raw record.authorized_for?(:crud_type => etc etc etc -%>

Anyway, thanks to floatless and hopefully mr hochstein will be able to use this stuff.

Answer 1

Try this:

return "<a class= disabled >#{text}</a>".html_safe unless authorized
