Interface: Repository<T>

Defined in: packages/models/lib/repositories/repository.d.ts:314

Full-featured repository combining all capabilities (backward compatible)

This is the main interface that most code will interact with. It extends all specialized interfaces for backward compatibility.

Note: All methods are inherited from:

• CoreRepository: Basic CRUD, query, and key management
• Updatable: Update, patch, and upsert operations
• AtomicOperations: Atomic increment, setAttribute, removeAttribute
• CollectionOperations: Array/collection manipulation

Extends

• CoreRepository<T>
• Updatable<T>
• AtomicOperations<T>
• CollectionOperations<T>

Type Parameters

T

T extends ModelClass = ModelClass

Properties

[WEBDA_TEST]?

optional [WEBDA_TEST]?: object

Defined in: packages/models/lib/repositories/repository.d.ts:184

clear()

clear(): Promise<void>

Returns

Promise<void>

Inherited from

CoreRepository.[WEBDA_TEST]

Methods

aggregate()

aggregate<G, M>(spec, params?): Promise<AggregationResult<AggregatedRow<InstanceType<T>, G, M>>>

Defined in: packages/models/lib/repositories/repository.d.ts:117

Aggregate the store

repo.aggregate({ filter: "done = FALSE", groupBy: ["status"], metrics: { n: { count: "*" } } });

Type Parameters

G

G extends readonly _NonFunctionPropertyPaths<InstanceType<T>>[] = []

M

M extends Record<string, MetricSpec<InstanceType<T>>> = Record<string, MetricSpec<InstanceType<T>>>

Parameters

spec

AggregationSpec<InstanceType<T>, G, M>

filter, group by paths, metrics, ordering and limit

params?

QueryParameters

values for the placeholders of spec.filter

Returns

Promise<AggregationResult<AggregatedRow<InstanceType<T>, G, M>>>

the aggregated rows and whether the backend computed them natively

Inherited from

CoreRepository.aggregate

---

configureAggregation()

configureAggregation(options): void

Defined in: packages/models/lib/repositories/repository.d.ts:138

Configure the aggregation fallback policy, called by the owning store

Parameters

options

Partial<AggregationOptions>

options to override

Returns

void

Inherited from

CoreRepository.configureAggregation

---

configureMonitoring()?

optional configureMonitoring(options): void

Defined in: packages/models/lib/repositories/repository.d.ts:143

Configure the query monitoring policy, called by the owning store

Parameters

options

Partial<QueryMonitorOptions>

options to override

Returns

void

Inherited from

CoreRepository.configureMonitoring

---

count()

count(filter?, params?, options?): Promise<CountResult>

Defined in: packages/models/lib/repositories/repository.d.ts:133

Count the objects matching a filter

repo.count("status = 'open'", undefined, { max: 10000 }); // { value: 1234, relation: "eq", native: true }

ORDER BY, LIMIT and OFFSET of the filter are ignored; DELETE, UPDATE and SELECT field lists are refused. Backends without a native count scan the matching objects in memory, under the aggregation fallback policy. Counts bypass the model permissions: see countModelWithPermissions in @webda/core for a client total.

Parameters

filter?

WebdaQLString<InstanceType<T>>

the WebdaQL filter, optionally with ? or :name placeholders; empty counts everything

params?

QueryParameters

values for the placeholders: an array for ?, an object for :name

options?

CountOptions

max stops counting after max objects (relation "gte")

Returns

Promise<CountResult>

the count, whether it is exact and whether the backend computed it natively

Throws

AggregationError AGGREGATION_NOT_NATIVE when the backend has no native count and the policy is deny

Inherited from

CoreRepository.count

---

deleteMany()

deleteMany(statement, params?): Promise<number>

Defined in: packages/models/lib/repositories/repository.d.ts:159

Delete every object matching a DELETE [WHERE ...] [LIMIT n] statement, in bulk

Bulk operations bypass the model layer: no per-object repository event (Delete/Deleted), no model hook, no behaviour and no validation run, and no permission (canAct) is checked. Repositories are trusted internal APIs: application code exposing a bulk statement to clients must check permissions itself.

Stores use their native batch operation when they have one, otherwise the matching keys are collected first (up to LIMIT) and deleted with the store's per-key primitive.

Parameters

statement

Query | WebdaQLStatement<InstanceType<T>>

the DELETE statement, optionally with ? or :name placeholders, or its parsed form

params?

QueryParameters

values for the placeholders: an array for ?, an object for :name

Returns

Promise<number>

the number of objects deleted

Throws

if the statement is not a DELETE

Inherited from

CoreRepository.deleteMany

updateMany()

updateMany(statement, params?): Promise<number>

Defined in: packages/models/lib/repositories/repository.d.ts:176

Update every object matching an UPDATE SET a = v, ... [WHERE ...] [LIMIT n] statement, in bulk

Bulk operations bypass the model layer: no per-object repository event (Patch/Patched/Updated), no model hook, no behaviour and no validation run, and no permission (canAct) is checked. Repositories are trusted internal APIs: application code exposing a bulk statement to clients must check permissions itself.

SET targets may not be a primary key field nor a private (__) field, and must be fields of the model when its metadata lists them. Dotted targets (profile.verified) set a nested value, creating the intermediate objects. Each matching object is updated once, even when the SET changes a field of the WHERE.

Parameters

statement

Query | WebdaQLStatement<InstanceType<T>>

the UPDATE statement, optionally with ? or :name placeholders, or its parsed form

params?

QueryParameters

values for the placeholders: an array for ?, an object for :name

Returns

Promise<number>

the number of objects updated

Throws

if the statement is not an UPDATE, or a SET target is refused
