Rails - How to pass stars :: Context in compilation manually sass

I use the following code snippet to manually compile the sass manifest with some added variable overrides.

template = File.read("#{Rails.root}/app/assets/schemes/#{scheme}/css/styles.css.scss")

scheme_variables.each do |key, value|
  template << "$#{key}:#{value};\n"
end

engine = Sass::Engine.new(template, { 
  :syntax => :scss,
  :cache => false,
  :read_cache => false,
  :style => :compressed,
  :filesystem_importer => Sass::Rails::SassImporter,
  :load_paths => MyApp::Application.assets.paths,
  :sprockets => {
    :context => ?,
    :environment => MyApp::Application.assets
  }
})
output = engine.render

The constructor of Sass :: Engine wants to create a context and environment for asterisks in the hash parameter settings. What do I put in context? The first thing I tried was ...

:context => MyApp::Application.assets.context_class,

... but this gives me the following error: undefined method `font_path 'for #" when it gets into one of my sass helpers.

The second thing I tried was ...

:context => ActionController::Base.helpers,

... This fixed the problem with the asset helper, but when I try to import my glob import (for example, @import "mixins / *"), the following error is raised: undefined `depend_on 'method for #

I am using Rails 4.2 and sass-rails 5.0.3.
