propel

问题 I wrote a symfony task to fill a database of sample data. Here's a sample piece of code: gc_enable(); Propel::disableInstancePooling(); public function test() { for($i = 0; $i < 10000; $i++) { $this->doIt($i); } } public function doIt($i) { $user = new User(); $user->setUsername('user' . $i . "@example.com"); $user->setPassword('test'); $user->setFirstName('firstname' . $i); $user->setLastName('surname' . rand(0, 1000)); $user->save(); $user->clearAllReferences(true); $user = null; gc_collect

问题 I've recently delved into using an ORM in my CodeIgniter application and one i've gone for is Propel. Now this gives me the power to basically use Propels classes as the 'Model' but is this bad practive? So my controller code would be as follows: <?php class Page extends Controller { function __construct() { parent::__construct(); } function index() { $foo = FooQuery::create()->limit(10)->find(); $data['content'] = array('foo'=>$foo); $this->load->view('home', $foo); } } ?> I want to solve

问题 I'm writing a report with Propel and need to join the same table multiple times in order to get different stats for different date ranges using the same data. The issue appears to be that propel ignores multiple ->leftJoin() calls on a query. I think I need to alias each join so they can be treated individually but I can't find a way to do that. 回答1: Try addJoin() $c = new Criteria(); $c->addJoin(array(Table1Peer::ID,), array(Table2Peer::Table1Peer_ID,), Criteria::LEFT_JOIN); Looks like you

问题 I want to check if a table name is valid in Propel, and then do something with it such as get its PHP name. The problem is that I am using the DatabaseMap and it only contains tables that have been instantiated. For instance: $map = Propel::getDatabaseMap(); $map->getTableName('group'); // throws exception If I iterate over the tables: $tables = $map->getTables(); foreach ($tables as $key => $value) { echo $key; } It only outputs 'user'. It does not output any other tables in my database. Are

问题 I need get the name of all the tables that exist on my database. I am usin Propel like my ORM. Actully i have been trying on this form. $dbmap = \Propel::getDatabaseMap('data'); $tablastmp = $dbmap->getTables(); $tablas = array(); foreach ($tablastmp as $tablatmp) { $tablas[] = $tablatmp->getName(); } echo '<pre>'; print_r($tablas); echo '</pre>'; die(); but this return an array that is empty. array(); And I need that return something like that: array( [0] => 'clients', [1] => 'workers' );

问题 I am writing a query using the Propel ORM The query is of the form: select * from some_table where some_table.created_at = (SELECT MAX(some_table.created_at) from some_table); I got this far: $c = new Criteria(); $c->addSelectColumn('MAX('.self::CREATED_AT.')'); Anyone knows how to use Propel to do this, to save me writing RAW SQL? 回答1: Try: $c = new Criteria(); $c->add(SomeTable::CREATED_AT, '(SELECT MAX('.SomeTable::CREATED_AT.') FROM some_table)', Criteria::CUSTOM); 回答2: If you jhust want

问题 Is there any chance I can migrate only one database, if I have define multiple connections in my config.yml If I run propel:migration:diff --connection=a it still want to generate migration for all databases defined. My vendors propel/propel-bundle 1.2.7 Integration of Propel in Symfony2 propel/propel1 1.6.9 Propel is an open-source Object-Relational Mapping (ORM) for PHP5. 回答1: Yes, you can. Although I have Propel 1.7.1 I don't think this has changed since 1.6.9 . You have to create a

问题 In Doctrine i can: $q = Doctrine_Query::create() ->from('One o') ->where('t.text = ?', 'aaa') ->andWhere('h.text = ?', 'bbb') ->leftJoin('o.Two t') ->leftJoin('t.Three h') ->leftJoin('h.Four f') ->execute(); How can i make this in Propel from Symfony 1? 回答1: If you use propel before 1.6 , you have to follow You have to know the primary key for each relation. If it's id , it can be something like that: $c = new Criteria(); $c->add(TwoPeer::TEXT, 'aaa'); $c->add(ThreePeer::TEXT, 'bbb'); $c-

问题 I have the following Criteria in Propel: $q = \UserQuery::create(); $q->select(array('id', 'name')); $q->orderBy('name'); $q->setOffset($offset); $q->setLimit($limit); return $q->find(); This works fine, and gives me a two-dimensional array with id and name keys in the inner array, i.e. array( array("id" => 1, "name" => 'A'), array("id" => 2, "name" => 'B') ) However, if I run the following: $q = \UserQuery::create(); $q->select(array('id')); $q->orderBy('id'); $q->setOffset($offset); $q-
