6.7. Document Partial Updates
Author | Dariusz Górecki |

Since the v1.3.5
You can do partial updates of documents.
Normally this extension, when using
EmongoDocument::save()
will always replace all contents of document in DB with the actual values of fields in YoursEMongoDocument
instance (including all embedded documents etc.)
You can pass to EMongoDocument::update()
method a list of attributes for update, this will use an extreme efficient
Mongo $set
operator to update only listed fields, see example:
$model = ModelClass::model()->find(); // Find some document to work with // change some fields $model->field1 = 1; $model->field2 = 'value'; // Optional: run validation, of changed fields: $model->validate(array('field1', 'field2')); // Use partial update $model->update(array('field1', 'field2'), true /* <- second parameter indicates to use partial update mechanism */);
And thats it, this will only update those 2 fields, rest in DB will not be touched.
