method

update_attribute

v3.2.8 - Show latest stable - Class: ActiveRecord::Persistence

update_attribute(name, value)

public

Updates a single attribute and saves the record. This is especially useful for boolean flags on existing records. Also note that

Validation is skipped.
Callbacks are invoked.
updated_at/updated_on column is updated if that column is available.
Updates all the attributes that are dirty in this object.

This method has been deprecated in favor of update_column due to its similarity with update_attributes.

# File activerecord/lib/active_record/persistence.rb, line 180
    def update_attribute(name, value)
      name = name.to_s
      raise ActiveRecordError, "#{name} is marked as readonly" if self.class.readonly_attributes.include?(name)
      send("#{name}=", value)
      save(:validate => false)
    end
