[Rails] Different update methods

Common ones

update(attributes)

• The most common one

• Trigger everything like validation/callbacks and etc

# Updating one record:
Person.update(15, :user_name => 'Samuel', :group => 'expert')

# Updating multiple records:
people = { 1 => { "first_name" => "David" }, 2 => { "first_name" => "Jeremy" } }
Person.update(people.keys, people.values)

update!(attributes)

• Calls save! internally, so it raises exception if errored

• Others are the same as update

update_all

• Does not trigger callbacks or validations

User.update_all max_login_attempts: 3, must_change_password: true

update_attributes

• update_attributes triggers validations

• Rails 6 deprecated update_attributes so just use update

update_attribute

• update_attribute does not trigger validation

update_column and update_columns

• Avoid using these because not all hooks are triggered
