include partial in nanoc [haml]

Question

I have this in my Rules file:

compile '/gallery/' do  
  filter :haml
  layout :'gallery'
end  
...
compile '/' do  
  filter :haml
  layout :'default'
end  
...
route '/gallery/' do  
  nil
end
...
route '*' do  
  item.identifier.chop + '.' +item[:extension]
end

, so now my content/index.html goes through haml filter and compiles as output/index.html all well and good. My content/gallery.html holds this code which also goes through haml:

#gallery-container  

%ul.items-small  
  %li.item  
    - @item.children.each do |img|  
      %a{:href => "#{img.path}"}  

%ul.items-big  
  %li.item-big  
    - @item.children.each do |img|  
      %a{:href => "#"}  
        %figure  
          %img{:src => "#{img.path(:rep => :thumbnail)}"}  
          %figcaption.img-caption Caption  

,it gathers some images in content/gallery/ folder and when I set routing to output/gallery/index.html(to see the preview output spit out) I do get what I want, so all well and good still.

But now I would like to use that generated code as partial in my content/index.html, however when I try to include it like =render 'gallery' I do not get my expected code. In turn I get error message LocalJumpError: no block given (yield).

What should be in my layouts/gallery.html file?, if I put there <%= yield %> I get the above error, If i remove =render 'gallery' there is no error,
But if I put some text in layouts/gallery.html and have again that =render 'gallery' in my index.html I get literally that text in layouts/gallery.html, so it gets included and without error. So should I <%= yield %> that gallery code I am expecting into layouts/gallery.html and then call =render 'gallery' from index.html?? But that does not work. Also that layouts/default.html already has its own yield which is working, and then I try to use that =render in item which would be compiled through that yield. Am i doing it wrong way? I am lost!

All of my layouts file are :erb filtered.

So my question would be how to include this partial. Thanks!

Answer 1

After digging through the code I found another solution to this.

The render method is part of Helpers::Rendering, if you look at the source code you see that it calls filter_for_layout from the rules (github).

You therefore just need to add the following to your Rules file:

layout '/gallery/', :haml, encoding: 'utf-8'

That way as the gallery layout is rendered it will pass through the haml filter like the other layouts.

Answer 2

After some trying and erroring it seems that it should be done like this,

= items["/gallery/"].compiled_content

, if I put that into my content/index.html.haml file instead, I do get results which I expect, and my content/gallery.html.haml renders itself on that place. I am not yet shure, where would I use render for partials, and what is the difference in using that and this one I used here.
