我想安排我的代码更好一点。 我有这个看法,由giiant生成:
$form->field($model, 'land_id')->dropDownList(ArrayHelper::map(app\models\Land::find()->orderBy('name')->all(), 'id', 'name'), [ 'prompt' => Yii::t('app', 'Select'), 'disabled' => (isset($relAttributes) && isset($relAttributes['land_id'])),]);有人在这里告诉我,在stackoverflow,这不是很好。 所以我想转移这部分:
ArrayHelper::map(app\models\Land::find()->orderBy('name')->all(), 'id', 'name'进入模型。 这同样适用于网格过滤器下拉菜单:
'filter' => ArrayHelper::map(\app\models\base\Land::find()->asArray()->all(), 'id', 'name'),是否有意义? 我想是的,我希望如此。 我试图以模型2的方式实现它:
public function getAllAsArray() { return ArrayHelper::map(app\models\Land::find()->orderBy('name')->all(), 'id', 'name'); }要么
public function getAllAsArray() { return ArrayHelper::map($this->find()->orderBy('name')->all(), 'id', 'name'); }我想从View / Grid(Zip - Land)中调用它:
'filter' => $model->land->allAsArray,但我收到以下错误:未定义的变量:模型
然后尝试这种方式:
'filter' => function ($model) {$model->getLand()->one()->getAllAsArray();}, 'filter' => function ($model) {$model->getLand()->getAllAsArray();},那么我不会收到错误消息,但它也不起作用。
并以表格(Zip - Land)的形式显示:
$form->field($model, 'land_id')->dropDownList($model->land->allAsArray(), [ 'prompt' => Yii::t('app', 'Select'), 'disabled' => (isset($relAttributes) && isset($relAttributes['land_id'])),]);但我收到以下错误:调用成员函数getAllAsArray()null
你能指点我正确的方向吗? 我想我基本不了解某些事情,这让我感到困惑。 非常感谢您提前!
I would like to arrange my code a little bit better. I have this in view, generated by giiant:
$form->field($model, 'land_id')->dropDownList(ArrayHelper::map(app\models\Land::find()->orderBy('name')->all(), 'id', 'name'), [ 'prompt' => Yii::t('app', 'Select'), 'disabled' => (isset($relAttributes) && isset($relAttributes['land_id'])),]);Somebody has told me here on stackoverflow that it's not really nice. So I would like to transfer this part:
ArrayHelper::map(app\models\Land::find()->orderBy('name')->all(), 'id', 'name'into model. The same applies to grid filter dropdowns:
'filter' => ArrayHelper::map(\app\models\base\Land::find()->asArray()->all(), 'id', 'name'),Does it make sense? I think so, I hope so. I've tried to implement it in model Land 2 ways:
public function getAllAsArray() { return ArrayHelper::map(app\models\Land::find()->orderBy('name')->all(), 'id', 'name'); }or
public function getAllAsArray() { return ArrayHelper::map($this->find()->orderBy('name')->all(), 'id', 'name'); }and I wanted to call it from View/Grid (Zip - Land):
'filter' => $model->land->allAsArray,but I'm getting the following error: Undefined variable: model
then tried this way:
'filter' => function ($model) {$model->getLand()->one()->getAllAsArray();}, 'filter' => function ($model) {$model->getLand()->getAllAsArray();},then I get no error messages, but it's also not working.
and in Form (Zip - Land) the same way:
$form->field($model, 'land_id')->dropDownList($model->land->allAsArray(), [ 'prompt' => Yii::t('app', 'Select'), 'disabled' => (isset($relAttributes) && isset($relAttributes['land_id'])),]);but I'm getting the following error: Call to a member function getAllAsArray() on null
Can you please point me to the right direction? I think I don't understand something basically and this disturbes me. Thank you very much in advance!
