| 51 | + |
| 52 | +## Utilisation |
| 53 | + |
| 54 | +### Create a Repository |
| 55 | + |
| 56 | +```php |
| 57 | +use Prettus\Repository\Eloquent\Repository; |
| 58 | + |
| 59 | +class PostRepository extends RepositoryBase { |
| 60 | + |
| 61 | + public function __construct(Post $model) |
| 62 | + { |
| 63 | + parent::__construct($model); |
| 64 | + } |
| 65 | + |
| 66 | +} |
| 67 | +``` |
| 68 | + |
| 69 | +### Using the Repository in a Controller |
| 70 | + |
| 71 | +```php |
| 72 | + |
| 73 | +class PostsController extends BaseController { |
| 74 | + |
| 75 | + /** |
| 76 | + * @var PostRepository |
| 77 | + */ |
| 78 | + protected $repository; |
| 79 | + |
| 80 | + public function __construct(PostRepository $repository){ |
| 81 | + $this->repository = $repository; |
| 82 | + } |
| 83 | + |
| 84 | + |
| 85 | + public function index() |
| 86 | + { |
| 87 | + $posts = $this->repository->all(); |
| 88 | + ... |
| 89 | + } |
| 90 | + |
| 91 | + |
| 92 | + public function show($id) |
| 93 | + { |
| 94 | + $post = $this->repository->find($id); |
| 95 | + ... |
| 96 | + } |
| 97 | + |
| 98 | + public function store() |
| 99 | + { |
| 100 | + |
| 101 | + $post = $this->repository->create( Input::all() ); |
| 102 | + ... |
| 103 | + } |
| 104 | + |
| 105 | + public function update($id) |
| 106 | + { |
| 107 | + $post = $this->repository->update( Input::all(), $id ); |
| 108 | + ... |
| 109 | + } |
| 110 | + |
| 111 | + public function destroy($id){ |
| 112 | + $this->repository->delete($id) |
| 113 | + ... |
| 114 | + } |
| 115 | +} |
| 116 | +``` |
| 117 | + |
| 118 | +### Create a Criteria |
| 119 | + |
| 120 | +```php |
| 121 | +class MyCriteria implements \Prettus\Repository\Contracts\Criteria { |
| 122 | + |
| 123 | + public function apply($query) |
| 124 | + { |
| 125 | + $query = $query->where('user_id','=', Auth::user()->id ); |
| 126 | + return $query; |
| 127 | + } |
| 128 | +} |
| 129 | +``` |
| 130 | + |
| 131 | +### Using the Criteria in a Controller |
| 132 | + |
| 133 | +```php |
| 134 | + |
| 135 | +class PostsController extends BaseController { |
| 136 | + |
| 137 | + /** |
| 138 | + * @var PostRepository |
| 139 | + */ |
| 140 | + protected $repository; |
| 141 | + |
| 142 | + public function __construct(PostRepository $repository){ |
| 143 | + $this->repository = $repository; |
| 144 | + } |
| 145 | + |
| 146 | + |
| 147 | + public function index() |
| 148 | + { |
| 149 | + $this->repository->pushCriteria(new MyCriteria()); |
| 150 | + $posts = $this->repository->all(); |
| 151 | + ... |
| 152 | + } |
| 153 | + |
| 154 | +} |
| 155 | +``` |
| 156 | + |
| 157 | +Getting results from criteria |
| 158 | + |
| 159 | +```php |
| 160 | +$posts = $this->repository->getByCriteria(new MyCriteria()); |
| 161 | +``` |
| 162 | + |
| 163 | +Setting Criteria default in Repository |
| 164 | + |
| 165 | +```php |
| 166 | +use Prettus\Repository\Eloquent\Repository; |
| 167 | + |
| 168 | +class PostRepository extends RepositoryBase { |
| 169 | + |
| 170 | + public function __construct(Post $model) |
| 171 | + { |
| 172 | + parent::__construct($model); |
| 173 | + } |
| 174 | + |
| 175 | + public function boot(){ |
| 176 | + $this->pushCriteria(new MyCriteria()); |
| 177 | + $this->pushCriteria(new AnotherCriteria()); |
| 178 | + ... |
| 179 | + } |
| 180 | + |
| 181 | +} |
| 182 | +``` |
| 183 | + |
| 184 | +### Using the RequestCriteria |
| 185 | + |
| 186 | +RequestCriteria is a standard Criteria implementation. It enables filters perform in the repository from parameters sent in the request. |
| 187 | + |
| 188 | +You can perform a dynamic search , filtering the data and customize queries |
| 189 | + |
| 190 | +To use the Criteria in your repository , you can add a new criteria in the boot method of your repository , or directly use in your controller , in order to filter out only a few requests |
| 191 | + |
| 192 | +####Enabling in your Repository |
| 193 | + |
| 194 | +```php |
| 195 | +use Prettus\Repository\Eloquent\Repository; |
| 196 | +use Prettus\Repository\Criteria\RequestCriteria; |
| 197 | + |
| 198 | +class PostRepository extends RepositoryBase { |
| 199 | + |
| 200 | + /** |
| 201 | + * @var array |
| 202 | + */ |
| 203 | + protected $fieldSearchable = [ |
| 204 | + 'name', |
| 205 | + 'email' |
| 206 | + ]; |
| 207 | + |
| 208 | + public function __construct(Post $model) |
| 209 | + { |
| 210 | + parent::__construct($model); |
| 211 | + } |
| 212 | + |
| 213 | + public function boot(){ |
| 214 | + $this->pushCriteria(new RequestCriteria(app('request'))); |
| 215 | + ... |
| 216 | + } |
| 217 | + |
| 218 | +} |
| 219 | +``` |
| 220 | + |
| 221 | +Remember, you need to define which fields from the model can are searchable. |
| 222 | + |
| 223 | +In your repository set **$fieldSearchable** with their fields searchable. |
| 224 | + |
| 225 | +```php |
| 226 | +protected $fieldSearchable = [ |
| 227 | + 'name', |
| 228 | + 'email' |
| 229 | +]; |
| 230 | +``` |
| 231 | + |
| 232 | +You can set the type of condition will be used to perform the query , the default condition is "**=**" |
| 233 | + |
| 234 | +```php |
| 235 | +protected $fieldSearchable = [ |
| 236 | + 'name'=>'like', |
| 237 | + 'email', // Default Condition "**=**" |
| 238 | + 'your_field'=>'condition' |
| 239 | +]; |
| 240 | +``` |
| 241 | + |
| 242 | +####Enabling in your Controller |
| 243 | + |
| 244 | +```php |
| 245 | + public function index() |
| 246 | + { |
| 247 | + $this->repository->pushCriteria(new RequestCriteria(app('request'))); |
| 248 | + $posts = $this->repository->all(); |
| 249 | + ... |
| 250 | + } |
| 251 | +``` |
| 252 | + |
| 253 | +#### Example the Crirteria |
| 254 | + |
| 255 | +Request all data without filter by request |
| 256 | + |
| 257 | +*http://prettus.local/users* |
| 258 | + |
