Access an attribute from other model

This is a part of my model (Partner)

before_validation(on: :create) do
    self.name = name.upcase
    self.institution = institution.upcase
    self.position = position.upcase
    self.street = street.upcase
    self.neighborhood = neighborhood.upcase
    self.city = city.upcase
    self.state = state.upcase
    self.email = email.upcase
    self.birth_city = birth_city.upcase
    self.spouse = spouse.upcase
  end

street and neighborhood are attributes from address model. By this way, i´m getting an error before saving it to db. How can I solve it?

What you might be better doing is delegating those attributes to the Address model, and using autosave to have them persist when you save the Partner model..

class Partner
  has_one :address, autosave: true

  delegate :street, :neighborhood, to: :address

  # callback code here
end

If you want to upcase all attributes, you can use a combination of assign_attributes and transform_values:

before_validation(on: :create) do
  assign_attributes(attributes.transform_values(&:upcase))
end
