When it gives to ruby expression, like if statement, I don't know how to indent correctly.
%ul
%li foo
- if true
%li bar
The above code working, but the two %li doesn't aligned, which not elegant for me, become they are in the same level(I mean both are children of %ul)
Is there a more elegant way to do this?
Your best bet if you are concerned with formatting for readability is to escape haml with an erb: filter.
%ul
erb:
<li>foo</li>
<% if true %><li>bar</li><% end %>
Unfortunately in situations like this the indentations kinda make the code less readable, but bare in mind the view is not mean for a great amount a logic. As much as possible, you should use your controller and helpers to pull out logic from the view.
Ok - so here is what happens in my code when the case is 'a bit' more complicated than this one:
list.haml:
%ul
= render :partial => 'list_item', :locals => { value => 'foo', cond => true }
= render :partial => 'list_item', :locals => { value => 'bar', cond => false }
_list_item.haml:
- if cond
%li= value
but in a case as trivial as this I would probably not do it. Most cases tend to become less trivial eventually though.... The con with this approach is that you need to get to another file to see what actually happens. The pro is DRY.
