--------------------------------- sfPropelORMTaggableBehaviorPlugin --------------------------------- A behavior and a widget for symfony 1.x and propel 1.6 How to install -------------- - add this plugin as a git submodule in your project. From your project root: git submodule add git://github.com/matteosister/sfPropel15TaggableBehaviorPlugin.git plugins/sfPropel15TaggableBehaviorPlugin - enable the plugin in your **ProjectConfiguration** class *config/ProjectConfiguration.class.php* :: <?php require_once dirname(__FILE__) . '/../lib/vendor/symfony/autoload/sfCoreAutoload.class.php'; sfCoreAutoload::register(); class ProjectConfiguration extends sfProjectConfiguration { public function setup() { // ... $this->enablePlugins('sfPropelORMTaggableBehaviorPlugin'); // ... } } - add the **taggable** behavior to a class in your schema file *config/schema.xml* :: <table name="article"> <behavior name="taggable" /> <column name="id" type="integer" primaryKey="true" autoIncrement="true"/> <column name="title" type="varchar" size="255" /> <!-- ... --> </table> - rebuild your model :: php symfony propel:build-all - publish assets :: php symfony plugin:publish-assets Classes And Tables generated ---------------------------- The behavior creates a **taggable_tag** table that is populated with tags Then it creates a **%table%_tagging table** for every object in your model with the taggable behavior. This middle table is marked as **isCrossRef**, with two foreign keys, one on the object and one on the tag table. This integrates the tagging mechanism completely inside propel How to use ---------- Some examples: :: <?php $article = new Article(); // there are two ways to add tags. The propel way: $tag = new Tag(); $tag->setName('propel'); $article->addTag($tag); $article->save(); // or the addTags method, that directly accept strings, array or csv $article->addTags('symfony'); // a string with no comma is a single tag $article->addTags('linux, ubuntu'); // a string with comma is multiple tag $article->addTags('symfony'); // if the object is already tagged nothing happens $article->addTags(array('linus', 'torvalds')); // list of tags as an array // remove tags $article->removeTags('symfony'); $article->removeTags('linux, ubuntu'); $article->removeTags(array('linus', 'torvalds')); // retrieve tags $article->getTags() // PropelCollection of Tag object // Query object $articles = ArticleQuery::create()->filterByTagName('propel')->find(); // you could also use the propel generated method. filterByTagName is just a shortcut of $articles = ArticleQuery::create()->useArticleTaggingQuery()->useTagQuery()->filterByName('propel')->endUse()->endUse(); // if you have a tag object (for example in a list of article tagged with...) propel has already done the dirty job $tag = TagQuery::create()->findOneByName('symfony'); $articles = ArticleQuery::create()->filterByTag($tag)->find(); Tag widget! ----------- This plugin creates a tagging table with crossref attribute, that has one fk on the object table and one on the tag table. When this "many-to-many" relations occur, Propel admin generator comes out of the box with a nice multiple select to tag your objects. But if you want something more interactive there is a nice jquery powered widget. - Enable the sfTagHub module in your settings.yml file (for jquery requests): *app/backend/config/settings.yml* :: all: .settings: # ... enabled_modules: [..., sfTagHub] - Create a tag field with **sfWidgetFormInputTags** widget in your form class, and don't forget the validator both of them accept the taggable object as a parameter *lib/form/ArticleForm.class.php* :: class ArticleForm extends BaseArticleForm { public function configure() { // this is mandatory. Or the default multiple select widget will override the tags widget unset($this['article_tagging_list']); // change "article" with your propel table name. // .... $this->setWidget('tags', new sfWidgetFormInputTags(array('taggable' => $this->getObject()))); $this->setValidator('tags', new sfValidatorTags(array('taggable' => $this->getObject()))); } } - clear your cache :: php symfony cc Now your form has a widget with jquery autocomplete that read from the tag table. And a list of tags associated with a delete button and a nice fadeout effect. The tags are saved server side (when you hit "save" on your form). The tag deletion are made via ajax and the sfTagHub module. No "save" needed.
