conditional haml - if else nesting

Question

What I want is both whats in \"if\" and whats in \"else\" to include #main-block.

- if @transparency
  #content-inner{:style => \"background: url(../../../ima         


        

Answer 1

You can use a ternary operator to conditionally apply the style attribute:

#content-inner{ :style => @transparency ? "background: url(../../../images/illustrations/" + @transparency + ") no-repeat 88% 50%" : '' }
  #main-block

For a more complicated arrangement, for example manipulating multiple hash attributes, it's best to either use a helper method, or to move the common content to a partial.
