addError() — Adds a custom error to a model instance. This is useful when built-in validations don’t fully cover your business rules,
addErrorToBase() — Adds an error directly on the model object itself, not tied to a specific property. This is useful when the error applie
allChanges() — Returns a struct containing all unsaved changes made to an object since it was last loaded or saved. Each entry in the s

clearErrors() — Clears all validation or manual errors stored on a model object. You can clear all errors, or target specific errors eit
compareTo() — Compares the current model object with another model object to determine if they are effectively the same. This is usefu

errorCount() — Returns the number of errors this object has associated with it.
errorsOn() — errorsOn() returns an array of all errors associated with a specific property of a model object. You can also filter by
errorsOnBase() — errorsOnBase() returns an array of all errors associated with the object as a whole, not tied to any specific property.
hasChanged() — Returns true if the specified property (or any if none was passed in) has been changed but not yet saved to
hasErrors() — Checks whether a model object has any validation or other errors. It returns true if the object contains errors, or if a
hasProperty() — Checks if a given property exists on a model object. It’s useful for safely validating whether a field is defined before
isNew() — Returns true if this object hasn’t been saved yet (in other words, no matching record exists in the databas
isPersisted() — Returns true if this object has been persisted to the database or was loaded from the database via a finder
key() — Returns the value of the primary key for the object.
properties() — Returns a structure containing all the properties of a model object, where the keys are the property (column) names and
propertyIsBlank() — Returns true if the specified property doesn’t exist on the model or is an empty string.
propertyIsPresent() — Returns true if the specified property exists on the model and is not a blank string. This is the inverse o
reload() — Refreshes the property values of a model object from the database. This is useful when an object’s values might have cha
setProperties() — Allows you to set multiple properties of a model object at once. It is useful when you want to update a model with a str
toggle() — Assigns to the property specified the opposite of the property’s current boolean value.
update() — Updates an existing model object with the supplied properties and saves the changes to the database. It returns true if
updateProperty() — Updates a single property on a model object and saves the record immediately without running the normal validation proce
valid() — Runs the validation on the object and returns true if it passes it.
