Constructor Details

#initialize(options = {}) {|_self| ... } ⇒ Metal

see also Fields::InstanceMethods#initialize_fields

Parameters:

  • options (Hash<Symbol, Object>) (defaults to: {}) —

    Values to initialize the model with, each Key value pair should be a field name and value for the field to initialize with.

Yields:

  • (_self)

Instance Method Details

#post_initialize ⇒ void

This method returns an undefined value.

Final initialization method, use this as your own initialize method. Called after the fields have been initialized at the very end. if you need to change the model before it ever reaches the user use Fields::InstanceMethods#post_initialize_fields instead.

def post_initialize
end

#pre_initialize ⇒ void

This method returns an undefined value.

Pre initialization method, use this as a way to setup the model before its fields are initialized.

def pre_initialize
end

#to_h ⇒ Hash<Symbol, Object>

Converts the Model to a Hash, all fields will be converted to Hashes via #to_h

Returns:

  • (Hash<Symbol, Object>)
