Haml: how do I set a dynamic class value?

Question

I have the following html.erb code that I'm looking to move to Haml:

<span class="<%= item.dashboardstatus.cssclass %>" ><%= item.dashboardstatus.status %></span>

What it does is associate the CSS class of the currently assigned status to the span.

How is this done in Haml? I'm sure I'm missing something really simple.

was your solution the same as below? – Creepy

Answer 1

Not sure. Maybe:

%span{:class => item.dashboardstatus.cssclass }= item.dashboardstatus.status

how do you do it when your tag is not a direct html tag, but generated through a rails helper? – Vermiculate

Answer 2

You can do multiple conditional class selectors with array syntax:

%div{ class: [ ("active" if @thing.active?), ("highlight" if @thing.important?) ] }

This worked.

Where ever the link is to the page do something like this

  %div{"data-turbolinks" => "false"}
    = link_to 'Send payment', new_payments_manager_path(sender_id: current_user.id, receiver_id: @collaboration.with(current_user).id, collaboration_id: params[:id]), class: 'button'
