Instance Method Details

#from(record) ⇒ Object

Hydrate from a record — the only supported constructor. Extra arguments are forwarded to #initialize, so a form with its own constructor still works.

def from(record, ...) = new(...).hydrate(record)

#hibiki_attributes ⇒ Object

def hibiki_model
  model = @hibiki_model || __hibiki_inherited(:hibiki_model)
  raise "#{self} has no reactive_attributes declaration" if model.nil?

  model.is_a?(Module) ? model : model.to_s.constantize
end

#hibiki_type(name) ⇒ Object

Channel action params arrive as strings; casting through the model's own attribute type is the difference between done = "false" meaning false and meaning true.



81
 
# File 'lib/hibiki/rails/reactive_form.rb', line 81

def hibiki_type(name) = hibiki_model.type_for_attribute(name.to_s)

#reactive_attributes(model, *names) ⇒ Object

reactive_attributes Todo, :title, :done

The model may be a Class or a String/Symbol; a name is resolved on every use, so a form class under app/ never pins a constant across a Zeitwerk reload.
