Defined in:
lib/arrthorizer/context.rb

Overview

Make it possible to specify the context that Arrthorizer can evaluate from inside the controller:

class MyController

to_prepare_context do |c|
  c.defaults do
    { bookcase: Cms::Bookcase.find(params[:id]) }
  end

  c.for_action(:some_action) do
    arrthorizer_defaults.merge({ bookcase: Cms::Book.find(params[:id]).bookcase })
  end
end

end

class MyController

to_prepare_context do |c|
  c.defaults do
    params
  end
end

end

In non-Rails environments:

class MySomething

# probably include something like Arrthorizer::Config
to_prepare_context do |c|
  c.defaults do
    { bookcase: Cms::Bookcase.find(params[:id]) }
  end

  if params[:action] == :edit
    arrthorizer_defaults.merge { author: User.find(params[:author_id] }
  end
end

end
