Basic Features
PDO SupportSí
Transparent support for NoSQLSí Avialable cross sql and nosql datababase relations (https://github.com/yiisoft/yii2-mongodb)
How to invoke db-vendor-specific extensions?Sí SQL - Query Builder.
Array as a persistenceSí https://github.com/yii2tech/filedb
RestAPI as a persistence- To extend BaseActiveRecord
JSON string as a persistence- To extend BaseActiveRecord
Same model, multiple persistences- (no docs)
Basic Single-record operations (C,R,U,D)
Table Name MappingSí Using static method of active record. http://www.yiiframework.com/doc-2.0/guide-db-active-record.html#declaring-ar-classes
Field Name MappingSí
Map Entity to SubQuery- table = new Expression(..)
Map property to expression- (couldn't find docs)
Map native types (DateTime)Sí Active record behaviors
User-defined types (e.g. "23 USD")Sí Active record behaviors
Map field of related Entity ('currency' = currency_id->Model Currency.name)Sí $model->currency->name
Map field to sub-query on related entity (Client.balance = Client->orders->sum(total))- (couldn't find docs)
Entity to join multiple tables (adding new record populates both tables)No No native support.
Criteria, Scope, Conditions (Model will refuse to work with records that does not match criteria)
Support model-level criteriaNo
Soft-deleteSí Events and behaviors
Domain Model CriteriaNo Only for specific query: User::find()->byEmail('...')->active()->one()
Expression-based conditionNo Only for query: User::find()->andWhere('...')->all()
Criteria Compliance (new record must match condition)No
Dynamic criteriaNo Only Querying: User::find()->where(['a' => '1', 'b' => true])->all();
Query Building (Convert Model into Query object for further SQL tweaking)
Convert Model into Query ObjectSí \yii\db\ActiveRecord::find()
Raw expressionSí new \yii\db\Expression('...')
Nested/Composite Queries/ExpressionsSí Expression can be in any part of query
Reference domain-model field in queryNo Field is class property.
field, where, order, limitSí \yii\db\ActiveQuery
options, rollup, partition
UPDATE, DELETE, INSERT query buildingSí
REPLACE, TRUNCATE- Throught raw sql in \yii\db\Command
SHOW, DESCRIBE, CALL- Throught raw sql in \yii\db\Command
ALTER, CREATE query buildingSí
User-defined query templateSí (please link doc)
full support for OR conditions-
Use Domain logic in multi-record updateNo
Data Fetching (different ways to retrieve data from database)
Get All Data (2x array)Sí \yii\db\Query::all()
Associative Array (id=>value)
Select only required fields
Typecasting (e.g. DateTime)
Import (multiple records)
Respect domain model mapping (and criteria)
Single rowSí \yii\db\Query::one()
Single ValueSí \yii\db\Query::scalar()
Single ColumnSí \yii\db\Query::column()
IteratorSí
Bypass persistence mapping
Loading and Saving individual records
Load by IDSí User::findOne(1)
Load by other fieldSí User::findOne(['id' => 1])
Read-only Models
Model without primary key
Specify fields to loadSí User::find()->select([])->one()
Save only sends dirty fieldsSí
Guarded / Fillable properties
Object Hierarchy Model
Admin extends User, adds criteria (is_admin=1)No Can be done as wrapper: User::findAdmin(..) or custom CDbCriteria
Admin extends User, adds accessible fieldsNo
Extend model, add Join (Disjoined SubTypes)No
Extend model change table
Relations/References (One model can relate to another model. NOT A TABLE JOIN)
Model can define relation to other ModelSí Relations
One-to-ManySí
One-to-many traversal strategyUses classical eager/lazy loading approach. with() can help pre-fetch the data for related entities.
Lazy/Eager-loadingSí
One-to-OneSí
Many-to-ManySí relations() method of an entity can define.
Deep Many-to-Many traversal.- only with "to-one" references: $book->author->address->street; Executes multiple queries.
Cross-Persistence traversal- No docs.
Cross-persistence joins, aggregation, reporting
Multi-persistence join
UNION existing models
Domain-model Aggregation
Model to Model join
Multi-persistence UNION
Behaviours / Hooks
Before/After operationSí
Override standard C,R,U,D operationsSí
Persistence-specific hooks (to modify Query)- (no docs)
User-defined hooksSí
Auditing
Global Auditing
Store old/new field valuesSí
Revert action (undo) and replay (redo)No
Reactive actions
Store log in any persistenceNo
Override, Add fields to audit log
Custom eventsSí
Access to record-specific history- Through a custom query.
Date of creation, modificationSí \yii\behaviors\TimestampBehavior
User/IP creation, modificationSí \yii\behaviors\BlameableBehavior
