phpactiverecord

问题 I have an model with a relation, and I want to instantiate a new object of the relations type. Example: A person has a company, and I have a person-object: now I want to create a company-object. The class of the companyobject is defined in the relation, so I don't think I should need to 'know' that class, but I should be able to ask the person-object to provide me with a new instance of type company? But I don't know how. This is -I think- the same question as New model object through an

问题 Does anyone know if Laravel has some sort of library/plugin or tweak to use Data Mapper or to make Active Record behave like Data Mapper?. I'm not a Laravel user,so perhaps Eloquent is using a mix of Active Record and Data Mapper and I'm not aware of that. 回答1: So, we can implement the Data Mapper pattern into Laravel using Doctrine; Packagist: https://packagist.org/packages/atrauzzi/laravel-doctrine Laravel Doc: http://bundles.laravel.com/bundle/doctrine 来源： https://stackoverflow.com

问题 Right now if I try to eager load more than two objects deep in phpactiverecord, I get an error. Is something such as this: $conditions['include'] = array( 'playlists' => array('playlist_songs' =>array('song'))); User::find('first', $conditions); Just one level too much to try to retrieve? I'm getting an error Undefined offset: 0 whenever I try to use an association 3 levels deep. Thanks for any help or insight :D. Edit: So I've found a pattern that's a little odd. If I have array('playlist

问题 I am trying out php active record, it's a great ORM, however I am at a standstill. I have looked around google, blogs, phpactiverecord documentation as well as statckoverflow for days but have not been able to come across a suitable solution to this problem. I am able to carry out the basic CRUD (insert,fetch, modify and delete) operations however as soon as i validate an object property using a static $validates_uniqueness_of filter, i get Fatal error: Uncaught exception 'ActiveRecord

问题 I'm new to CodeIgniter and ORM, I hope you guys can help me with this. The question table: CREATE TABLE `question` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `title` varchar(128) NOT NULL DEFAULT '', `content` text NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; The answer table: CREATE TABLE `answer` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `question_id` int(11) unsigned NOT NULL, `content` text NOT NULL, PRIMARY KEY (`id`), KEY `question_id` (`question_id`

问题 I'm using ActiveRecord and I need switching databases. When I log-in I select a database. The databases are the same schema. I tried: $connections = array( '1' => 'mysql://root:pass@localhost/db1;charset=utf8', '2' => 'mysql://root:pass@localhost/db2;charset=utf8', 'test' => 'mysql://root:password@localhost/database_name' ); $current_db = $_SESSION['db'] ? $_SESSION['db'] : '2'; ActiveRecord\Config::initialize(function($cfg) use ($connections, $current_db) { $cfg->set_model_directory(MODEL

问题 I made a website with CodeIgniter and I am currently hosting it with 1and1 . During development, everything looked golden. Only if all hosts were as reliable as localhost. I am looking to get the PHP error logs from the site. Unfortunately, 1and1 does not allot access to their Apache logs. How can I get error logs? Debugging fatal errors is a pain without logs. What I have tried? The custom error logging function Modifying the local PHP.ini to allow/log errors Used php5 by adding the

问题 How do I check if the initialisation was successful after I do this? ActiveRecord\Config::initialize(function($cfg){ $cfg->set_model_directory('models'); $cfg->set_connections(array( 'development' => "mysql://root:root@localhost/blog" )); }); And then I go onto doing something like: $posts = Post::all(); Just before performing the above I'd like to check if the initialization was successful. With a PDO object I could do: if $con ? /*execute query*/ : /*failed to connect*/ How could I achieve

问题 I'm using php.activerecord, and I am trying to link two tables. I have contacts and contactCompanyLinks . Each contact can contain one or more rows in the link table. The field names in the table don't follow any sensible convention, but I can't change it as it would break another app using the same table. The primary key of contacts is called contactID , and the foreign key in contactCompanyLinks is called inspectorID . php.activerecord makes way too many assumptions, and I can't figure out

问题 I have to make some filters, such as get persons who are in a given department, and I was wondering about the best way to do it. Some of them are going to require the join of multiple tables. Does anyone know about the main differences between CDbCriteria and Query Builder? I would particularly like to know about the compatibility with databases. I found this in the Yii documentation about Query Builder: It offers certain degree of DB abstraction, which simplifies migration to different DB
