CakePHP ORM Contain

Eager Loading Associations Via Contain¶ By default CakePHP does not load any associated data when using find(). You need to 'contain' or eager-load each association you want loaded in your results. Eager loading helps avoid many of the potential performance problems surrounding lazy-loading in an ORM. The queries generated by eager loading can better leverage joins, allowing more efficient queries to be made. In CakePHP you define eager loaded associations using the 'contain' method L'ORM intégré dans CakePHP se spécialise dans les bases de données relationnelles, mais peut être étendu pour supporter des sources de données alternatives. L'ORM de CakePHP emprunte des idées et concepts à la fois des patterns de ActiveRecord et de Datamapper. Il a pour objectif de créer une implémentation hybride qui combine les aspects des deux patterns pour créer un ORM rapide et facile d'utilisation For the example lets take 3 tables: country_of_residence_history (related to users with belongsTo association type) users (related to transaction with hasMany association type) transactions (belon..

Fields can be passed as an array of strings, array of expression objects, a single expression or a single string.

Build the map of. dependent: Set to true if you want CakePHP to cascade deletes to the associated table when an entity is removed on this table. Set to false if you don't want CakePHP to remove associated data, for when you are using database constraints. cascadeCallbacks: Set to true if you want CakePHP to fire callbacks on cascaded deletes. If false the ORM will use deleteAll() to remove data. When true records will be loaded and then deleted Is Cake having difficulty associating this back to its parent association when I specify a list finder? Yes it is. The issue is that your keyField is a non-distinct field, this results in values being overwritten when the result set is built, causing the ORM not being able to attach the data to the source entity.. If you were to use an distinct field as the keyField you still would have issues.

Contribute to cakemojo/cakephp-orm-by-example development by creating an account on GitHub I'm migrating a web app that was built using cakephp 1.3 and it took advantage of setting limits on a lot of hasMany relations, which has been removed in 3.x. Looking at the SQL debug on that site I see 1.3 just selected them as a seperate statement using IN(id,id,id). I understand the SQL structure is much better in 3.1 reducing the amount of selects but if you clever guys can work out a way. CakePHP ORM LazyLoad Plugin. This is an association lazy loader for CakePHP ORM entities. It allows you to lazily load association data by accessessing the property, without using contain() (the eager loader). Installation.
