Rails - Jul 2008 - Django-like nested templates with Rails layouts

Hi everyone

I''ve been briefly flirting with Django, and have decided that
I''m
going to stick with Ruby on Rails for the time being. The only thing I
think I''m going to miss is Django''s implementation of nested
templates.

Thinking my way through it now, the closest I can think of would be to
bundle the common content off into a load of partials (say "header",
"menu", "footer" and so on). While this is better in that
changing
things within the partials would be accomplished in just one place,
but it would still result in a bunch of files with very similar
content, that would all need amending should I want to add an extra
partial to each layout.

Has anyone got any strategies or ideas for accomplishing gives you?

Thanks
Jon

I don''t know, what exactly "nested templates" in Django do...

But you can nest partials into each other as deep as you like, you can
even nest one in itself recursively.
<%= render :template => "another_partial" %>
or you can use the content_for thingy in a layout (eg for the menu
part)

say:
<%= yield :some_menu %>

and then in the partial to be rendered:
<% content_for :some_menu %>
  .. some html here...
  ...or another render :partial => :whatever_menu...
<% end %>

There are so many ways to define & render partials, hand in some
data to them with :locals, :object and so on, that I can''t imagine
much
you ould not do with them.

If you want to nest layouts within layouts (which it doesn''t appear  
you want to do, but I think it''s worth mentioning anyway), you can use
the nested_layouts plugin.
