method

update_attribute

v7.2.3 - 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 raises an ActiveRecord::ActiveRecordError if the attribute is marked as readonly.

Also see #update_column.

# File activerecord/lib/active_record/persistence.rb, line 532
    def update_attribute(name, value)
      name = name.to_s
      verify_readonly_attribute(name)
      public_send("#{name}=", value)

      save(validate: false)
    end
