doctrine

问题 I create a new Entity with an existing Id , and I want to update the related database record. Doctrine merge has been my best friend: recognizes if there are changes and generates the correct update query. $entity = new Entity(); $entity->setId(1); $entity->setName('test'); $EntityManager->merge($entity); $EntityManager->flush(); Suppose that the element with the id=1 already exists in the db: if the name is different from 'test', Doctrine generates this query: UPDATE table SET name = ? WHERE

问题 Situation: I want to use the getReference() function of doctrine2 Entity Manager. However, in a situation where I ask for an object that has been deleted from the database, I obtain a proxy if I ask for that same object more than once. An example: //A random article object...that has been deleted from the database $articleClass = 'Acme\ArticleBundle\Entity\Article'; $articleIdentifiers = array('id'=>1); $i = 0; //We ask for its reference twice do{ try { echo "a"; $subject = $this->em-

问题 I use Loggable behavioral extension to log changes in my entities. I want to log changes in manyToMany relations too. I want to show to user this kind of change log: +--------------------------------------------------+ | Article "My Article" change log: | +-------+------------+-----------------------------+ | Who | When | What | +-------+------------+-----------------------------+ | Admin | 2015-07-01 | Removed tags "tag1", "tag2" | | Admin | 2015-07-01 | Added tags "tag3" | +-------+--------

问题 I have a project on Symfony2. I should say that I don't consider myself a master of Symfony2 in any way. You could say I'm a newbie. My entities are bound via YAML to database and an Entity class is created in php not bound by annotations. I have an Entity likes this: Project/CoreBundle/Resources/config/doctrine/Card.orm.yml Project/CoreBundle/Entity/Card.php Card - is a dashboard element, that can be dragged around for user's convenience. The corresponding Card.orm.yml and Card.php have

问题 I'm generating migrations between different yaml schema files: i.e. running: symfony doctrine:generate-migrations-diff And the resulting migration file has a whole slew of changeColumn calls that weren't added in the last schema file change. For example, if you run generate-migrations-diff without changing your schema file whatsoever, you should get an empty up() function. However, the function that results for me has a changeColumn call for virtually every table in my database. Am i doing

问题 let's say I have 3 databases: prefix_db1 prefix_db2 prefix_db3 And I want to connect to them dynamically from the url like this http://localhost/my-project/web/app_dev.php/db1/books so I know which database to conenct to from the url (in this case prefix_db1 ) And basically the idea was to prepare a listener that will be fired with each http request , get the database name from the url and then override doctrin's params, something like this: Within services.yml : dynamic_connection: class:

问题 I read official documentation and tons of threads but still do not find solution for my situation. My case is very basic. I have 2 entities: comments and keywords for them. One comment can have many keywords but each keyword is only for one comment. Keywords are not unique in keyword table. So i decided this is one-to-many relation. Tables structure are simply like follows: keywords id int(11) comment_id int(11) text varchar(30) comments id int(11) text text here is how i mapped them: /** *

问题 I have added SonataUserBundle and it is giving error config.yml doctrine: orm: auto_generate_proxy_classes: "%kernel.debug%" naming_strategy: doctrine.orm.naming_strategy.underscore auto_mapping: true entity_managers: default: mappings: ApplicationSonataUserBundle: ~ SonataUserBundle: ~ error Unrecognized options "naming_strategy, auto_mapping, dql" under "doctrine.orm" 回答1: You are mixing shortened and full configuration. If you just want to use the default entity manager then you can place

问题 Im trying to reproduce this query: SELECT * FROM `request_lines` where request_id not in( select requestLine_id from `asset_request_lines` where asset_id = 1 ) in doctrine query builder, I am stuck on the where request_id not in(select I currently have: $linked = $em->createQueryBuilder() ->select('rl') ->from('MineMyBundle:MineRequestLine', 'rl') ->where() ->getQuery() ->getResult(); 回答1: You need to use query builder expressions, and this means you need access to the query builder object.

问题 Could someone explain in detail how to integrate Doctrine 2 and Zend Framework 1.11? 回答1: There is a great video by Jon Lebensold about integrating D2 and ZF: Unit Testing Doctrine 2 - don't be misleaded by the title :) 回答2: I know this is a late inclusion but I just did this following the Zend webinar recording at http://www.zend.com/en/webinar/Framework/70170000000bSrG-webinar-zf-v-1-doctrine-v-2-20101214.flv (you need a (free) Zend account to view it).
