HAML: Create container/wrapper element only if condition is true

Question

Longshot, but I\'m wondering if there\'s any way to do something like this:

%p # ONLY SHOW THIS IF LOCAL VARIABLE show_paras IS TRUE
  = name

Answer 1

You could use raw html, but then you'd have to have the if statement both at the beginning and end:

- if show_paras
  

= name
- if show_paras
  

Assuming you're doing more than just = name, you could use a partial:

- if show_paras
  %p= render "my_partial"
- else
  = render "my_partial"

You could also use HAML's surround (though this is a little messy):

- surround(show_paras ? "
" : "", show_paras ? "
" : "") do
  = name

Finally, what I would probably do is not try to omit the p tag at all, and just use CSS classes to set up two different p styles to look the way I want:

%p{:class => show_paras ? "with_paras" : "without_paras"}
  = name
