Module: Sohm::Utils

Defined in:

Overview

Instead of monkey patching Kernel or trying to be clever, it’s best to confine all the helper methods in a Utils module.

Class Method Details

.const(context, name) ⇒ Object

Used by: ‘attribute`, `counter`, `set`, `reference`, `collection`.

Employed as a solution to avoid ‘NameError` problems when trying to load models referring to other models not yet loaded.

Example:

class Comment < Sohm::Model
  reference :user, User # NameError undefined constant User.
end

# Instead of relying on some clever `const_missing` hack, we can
# simply use a symbol or a string.

class Comment < Sohm::Model
  reference :user, :User
  reference :post, "Post"
end

    # In JRuby, Module::const_get can not work on nested symbols
    # such as "Foo::Bar", so we have to do it piece by piece here
    pieces = name.to_s.split("::")
    pieces.reduce(context) { |context, piece| context.const_get(piece) }
