save
save(**options, &block)Saves the model.
If the model is new, a record gets created in the database, otherwise the existing record gets updated.
By default, save always runs validations. If any of them fail the action is cancelled and #save returns false, and the record won’t be saved. However, if you supply validate: false, validations are bypassed altogether. See ActiveRecord::Validations for more information.
By default, #save also sets the updated_at/updated_on attributes to the current time. However, if you supply touch: false, these timestamps will not be updated.
There’s a series of callbacks associated with #save. If any of the before_* callbacks throws :abort the action is cancelled and #save returns false. See ActiveRecord::Callbacks for further details.
Attributes marked as readonly are silently ignored if the record is being updated.
