Each table name must be lowercase underscore prefixed and model class name must be StudlyCaps.
Importing Model Class
Model classes are autoloaded by Composer when you create an object of model class. Specify model namespace in controller using use keyword. Create an object of model class and do stuffs.
namespace Apps/Controllers; use Apps/Models/User;
Accessing Model Functions
Sometime you may need to create a model function to modify the object or use filters over data, such scenario create an function in the model class and access using class object. For more details about model filters read Activerecord documentation.
use Apps/Models/User; $user = new User(); $user->getUsers();
Accessing model directly in view pages is anti pattern, but sometime you want to access to do some stuffs. You can access model data similarly by creating object of the class.
Model class is a wrapper over Cyrus ActiveRecord orm, all features are accessible using model. Read more about database related stuffs on cyrus ActiveRecord, Finders, Schema Builder, Migrations etc. documentation.
That's all small introduction of model class. But there are more stuffs you can do with your simple model class.
