Instance Method Details

#adapter(&block) ⇒ Object

The default adapter to use.

Pass a block to assign the adapter, and invoke without a block to return the configured adapter instance.

 Flipper.configure do |config|
   config.adapter # => instance of default Memory adapter

   # Configure it to use the ActiveRecord adapter
   config.adapter do
     require "flipper/adapters/active_record"
     Flipper::Adapters::ActiveRecord.new
   end

   config.adapter # => instance of ActiveRecord adapter
end

  end
end

#default(&block) ⇒ Object

Controls the default instance for flipper. When used with a block it assigns a new default block to use to generate an instance. When used without a block, it performs a block invocation and returns the result.

configuration = Flipper::Configuration.new
configuration.default # => Flipper::DSL instance using Memory adapter

# sets the default block to generate a new instance using ActiveRecord adapter
configuration.default do
  require "flipper/adapters/active_record"
  Flipper.new(Flipper::Adapters::ActiveRecord.new)
end

configuration.default # => Flipper::DSL instance using ActiveRecord adapter

Returns result of default block invocation if called without block. If called with block, assigns the default block.
