Question

I have a <tr> element in my view, and I want to add classes dynamically on this element depending on an association between two models (many to many between company and packaging).

The result should looks like

<tr class="pck1 pck3 pck5">

where pck1, pck3 and pck5 are packagings associated with a company.

Answer 1

or simply:

%tr{ :class => classes }
