Haml add class dynamically to an element

Question

Hi,

I've an element TR in my view, I want to add classes dynamically on this element depending on an association between 2 models (many to many between company and packaging).

The result should looks like

<tr class="pck1 pck3 pck5">

where pck1, pck3 and pck5 are packaging associated with a company

Thanks for your insights

Answer 1

Say you have an array classes = ['pck1', 'pck3', 'pck5'] with the classes you want your tr to have.

Just type something like:

%tr{:class => classes.join(' ')}

Answer 2

or simply:

%tr{ :class => classes }
