# new Repository()
The Repository class extends BaseRepository to provide additional validation functionality. It overrides prefix methods to perform model validation before database operations and throws ValidationError when validation fails.
Concrete repository implementation with validation support.
Example
class UserModel extends Model {
Methods
# async protected createAllPrefix(models, args) → {Promise.<Array.<any>>}
Overrides the base createAllPrefix method to add validation checks for multiple models. Creates a context, instantiates new models, enforces decorators, and validates each model before allowing creation to proceed. Collects validation errors from all models.
Prepares multiple models for creation with validation.
Parameters:
| Name | Type | Description |
|---|---|---|
models |
Array.<M>
|
The array of model instances to prepare for creation |
args |
Array.<any>
|
Additional arguments for the create operation |
If any model fails validation, with details about which models failed
A promise that resolves to an array containing the validated models and context arguments
Promise.<Array.<any>>
# async protected createPrefix(model, args)

Parameters:
| Name | Type | Description |
|---|---|---|
model |
M
|
The model instance to prepare for creation |
args |
Array.<any>
|
Additional arguments for the create operation |
If the model fails validation
A promise that resolves to an array containing the validated model and context arguments
# async protected updateAllPrefix(models, args)
Overrides the base updateAllPrefix method to add validation checks for multiple models. Creates a context, validates primary keys, retrieves existing models, merges old and new models, enforces decorators, and validates each model before allowing updates to proceed.
