Hey,
in ERB it was possible to use tap to not repeat some calculations, e.g.:
<% Model.some_complex_query.tap do |result| %>
<%= something if result.size > 0 %>
<% result.each {} %>
<% end %>
and so on...
When I try similar thing it in Haml it displays the value of the tapped
object after executing the block.
- "string".tap do |s|
-# nothing here
will display "string", because it simply executes the code and #tap returns
the original object after executing the block. Is there a way to get similar
behavior as in ERB?
Cheers,
Szymon
