locals hash not supported in current implementation of Stache::Mustache::Handler

[lulu-2021]

Currently the Stache::Mustache::Handler compile method only passes controller instance variables to the view context - however in many circumstances you want to have more control over the render method - ie. not use the standard rails automagic way..

I would like to see this added to the compile method so that the locals hash is supported:

      local_assigns.each do |key, val|
        variable_name = '@'.concat(key.to_s).to_s.to_sym
        variables << variable_name
        mustache.instance_variable_set(variable_name, val)
      end

that would enable me to do something like this in the controller#action

render 'people/new', locals: { person: person }

and therefore not have to create an instance variable as person becomes an attr_reader etc..

I am happy to provide you with a pull request if you like - Thanks

Steve

Just as an aside - Poirot also supports this - i.e. it is pretty standard..

https://github.com/olivernn/poirot/blob/master/lib/poirot/view.rb

if Rails.version >= "3.1"
# get the locals from the view context, is there a better way?
locals = view_context.send(:view_renderer).send(:_partial_renderer).instance_variable_get("@Locals") || {}

    locals.each do |name, val|
      instance_variable_set("@#{name}", val)
      self[name] = val
    end
  end
