问题 I was wondering if there is a way to declare the default order for my doctrine models. e.g. I have a work model and it has photos . When I load a work, all photos associated to it get loaded into $work->photos . When I display them, they are ordered by their IDs. It would be very convenient to declare a default order on another field or perhaps override the fetch behaviour altoghether. I'd rather not to convert the photos to an array and use usort. Thanks. 回答1: You can specify it in the YAML

问题 I am new to Symfony and am finally beginning to understand how to query a database using a Doctrine. However, I am lost as far understanding how to use the database object content in a Twig template. Lets say my database object contains product Id's, names, prices, for 50 different products. After I am done querying the database in the controller, I do the following, to pass the database object into the Twig template: public function searchAction($word) { //query database using the $word slug

问题 I need to add some extra fields to a bunch of entities/classes and i would like to get those fields included in each entity/class. I could write all the fields in each class and it will work but i'm looking for a way to centralize the definitions of the fields and related methods, just to make it more maintainable and let me distribute modification, just editing a single file. I got it working using inheritance but in that manner, there will be a parent class/table, which will keep track of

I've added a couple of virtual columns as detailed on this page http://www.symfony-project.org/jobeet/1_4/Doctrine/en/12 What I want to be able to do is sort my list based on those virtual columns. http://redotheweb.com/2008/09/25/sorting-by-custom-column-in-the-symfony-admin-generator/ That is how to do it with the Propel plugin but that details the use of a "sort_method" configuration in the yaml generator file, no such configuration

The haversine formula is good enough for what I want to do 6371 * ACOS(SIN(RADIANS( $lat )) * SIN(RADIANS( latitude )) + COS(RADIANS( $lat )

问题 I'm using Doctrine with Zend Framework. I have to create both the DB schema and the Doctrine entities with annotations. Since the annotations already contain the information, it should be possible to create/update the schema based on them. I don't want to reinvent the wheel, so I was wondering whether that kind of logic already existed? 回答1: You can use the doctrine CLI, for a lot of doctrine related tasks. I'm not sure how doctrine is integrated into Zend, but look for the doctrine.php, and
