README
Hierarchical hydrator for ActiveRecord with support for relations and sorting.
Usage
$document = new \x1\data\ActiveDocument([ 'model' => Order::className(), // 'useTransaction' => true, // 'defaultIncremental' => false, // 'defaultIgnoreError' => false, // 'defaultDelete' => true, // 'defaultScenario' => null, // 'defaultSkipUpdate' => false, // 'defaultIgnoreError' => false, 'relations' => [ 'orderItems' => [ // 'incremental' => false, // sets relations as passed by data and unlinks omitted rows // 'skipUpdate' => false, // models are save, otherwise they are skipped // 'delete' => true, // deletes dropped models, otherwise they are only unlinked // 'scenario' => null, // the scenario to use for validation // 'useTransaction' => true, // wraps all operations in a transaction // 'sortable' => null, // (string) name of the order column (=int field) 'relations' => ['supplier'], // other relations of 'orderItem', maybe nested ] ], ]); $model = $document->findOne(1); // find the model and quietly attach ActiveDocumentBehavior $model->load($data); // relations are set!
incremental => false
(default) unlinks all orderItems except the ones passed in$data
.- additionally to unlink,
delete => true
also deletes these models. it has no effect onincremental => true
- if relation configuration values are not explicitly set, the default values at root level are used
pass all needed relations to the configurations array. you can customize the processing of related data as shown below, like link/unlink and delete/skip behavior.
Data Example
// data from post $data = [ 'Order' => [ 'id' => 1, 'title' => 'Order #1' 'orderItems' => [ ['id' => 1, 'msg' => 'order item #1'], ['id' => 2, 'msg' => 'order item #2'], [ 'msg' => 'unsaved order item #3'], ] ] ]
Behind the scene
- The
ActiveDocument
helper class just attaches theActiveDocumentBehavior
to an ActiveRecord - For each relation, the
RelationValidator
is attached. This allows capturing the relation's setter (when loading) - Now
$model->load($data)
also cares about relations. - On before save, a transaction is opened
- If everything is valid (ignoring those models, who skipError), we can finally save
Commit
orRollback
the transaction- use
$model->getErrorDocument()
and$model->getDocument()
