Instance Method Details

#characterize(name, properties, type = Metadata) ⇒ Metadata

Creates a metadata instance for the relation.

  • options (Hash) —

    The options for the relation.

  • type (Class) (defaults to: Metadata) —

def characterize name, options, type = nil
  type ||= Mongoid::SleepingKingStudios::Concern::Metadata
  type.new name, options
end

#relate(base, name, metadata) ⇒ Object

Stores the metadata in the class’s relations object. To avoid automatic Mongoid behavior on relations, adds a #sleeping_king_studios accessor to the relations hash by mixing in the Relations module. Then, saves the metadata using the metadata#relation_key as the key.

Parameters:

  • base (Class) —

    The base class into which the concern is mixed in.

  • name (Symbol) —

    The name of the relation. Must be unique for the base type within the sleeping_king_studios namespace.

  • metadata (Metadata) —

    The metadata to be stored.

Since:

  • 0.6.0

#valid_options ⇒ Array<Symbol>

Returns:

    The list of valid options.

Since:

#validate_options(name, options) ⇒ Object

Parameters:

  • name (Symbol) —

    The name of the relation.

  • options (Hash) —

    The options for the relation.

Raises:

  • (Mongoid::Errors::InvalidOptions) —

    If any of the options provided are invalid.

Since:
