Class Method Details

.option(option_name, &block) ⇒ Object

Stores the provided block to be run when the option name specified is defined on a field.

No assumptions are made about what sort of work the handler might perform, so it will always be called if the ‘option_name` key is provided in the field definition – even if it is false or nil.

Examples:

Mongoid::Fields.option :required do |model, field, value|
  model.validates_presence_of field if value
end

Parameters:

  • option_name (Symbol) —

    the option name to match against

  • block (Proc) —

    the handler to execute when the option is provided.

Since:

  • 2.1.0

end

.options ⇒ Hash

Return a map of custom option names to their handlers.

Examples:

Mongoid::Fields.options
# => { :required => #<Proc:0x00000100976b38> }

Returns:

  • (Hash) —

    the option map

Since:

  • 2.1.0
