Model

Basic Usage

// Defining An Eloquent Model
class User extends Model {}
// generate Eloquent models

}

Model::create(array('key' => 'value'));
// Find first matching record by attributes or create
Model::firstOrCreate(array('key' => 'value'));
// Find first record by attributes or instantiate

// Create or update a record matching attibutes, and fill with values
Model::updateOrCreate(array('search_key' => 'search_value'), array('key' => 'value'));
// Fill a model with an array of attributes, beware of mass assignment!
Model::fill($attributes);
Model::destroy(1);
Model::all();
Model::find(1);
// Find using dual primary key
Model::find(array('first', 'last'));
// Throw an exception if the lookup fails
Model::findOrFail(1);
// Find using dual primary key and throw exception if the lookup fails
