Views / Templates
Templates are assumed to be located directly under the ./views directory. To use a different views directory:
set :views, File.dirname(__FILE__) + '/templates'
One important thing to remember is that you always have to reference templates with symbols, even if they’re in a subdirectory (in this case, use :'subdir/template'). You must use a symbol because otherwise rendering methods will render any strings passed to them directly.
Accessing Variables in Templates
Templates are evaluated within the same context as route handlers. Instance variables set in route handlers are directly accessible by templates:
get '/:id' do
@foo = Foo.find(params[:id])
haml '%h1= @foo.name'
end
Or, specify an explicit Hash of local variables:
get '/:id' do
foo = Foo.find(params[:id])
haml '%h1= bar.name', :locals => { :bar => foo }
end
This is typically used when rendering templates as partials from within other templates.
