在我的 Yii 2 项目中，我有一个使用 yii2-dynamicform 的嵌套动态表单延期。我可以让它在 wiki guide 之后工作, 但我不得不在 this StackOverflow question 中寻求帮助使其正常工作。 但是当我尝试添加更多字段时，我在更新时遇到了一个小问题。
在解释之前，让我展示一下我的场景:
我的问题:
更新一条记录，当我点击添加一个新的插槽字段时，它不是只添加一个，而是添加我已经添加的组数。
例如: 在上图中，我有两个组(group1 和group2)。如果我点击添加一个插槽，它会一次添加两个(组数)插槽。
谁能帮帮我，好吗？
我在 Controller 中的 actionUpdate:
public function actionUpdate($id)
{
$model = $this->findModel($id);
$oldGrupoIds = MissaoGrupo::find()->select('id')->where(['missao_id' => $id])->asArray()->all();
$oldGrupoIds = ArrayHelper::getColumn($oldGrupoIds, 'id');
$modelsGrupos = MissaoGrupo::findAll(['id' => $oldGrupoIds]);
$modelsGrupos = (empty($modelsGrupos)) ? [new MissaoGrupo] : $modelsGrupos;
$oldSlotIds = [];
foreach ($modelsGrupos as $i => $modelGrupo) {
$oldSlots = MissaoSlot::findAll(['grupo_id' => $modelGrupo->id]);
$modelsSlots[$i] = $oldSlots;
$oldSlotIds = array_merge($oldSlotIds, ArrayHelper::getColumn($oldSlots, 'id'));
$modelsSlots[$i] = (empty($modelsSlots[$i])) ? [new MissaoSlot] : $modelsSlots[$i];
}
if ($model->load(Yii::$app->request->post())) {
$modelsGrupos = Model::createMultiple(MissaoGrupo::classname(), $modelsGrupos);
Model::loadMultiple($modelsGrupos, Yii::$app->request->post());
$newGrupoIds = ArrayHelper::getColumn($modelsGrupos, 'id');
$newSlotIds = [];
$loadsData['_csrf'] = Yii::$app->request->post()['_csrf'];
$i = 0;
foreach ($modelsGrupos as $id => $value) {
$loadsData['MissaoSlot'] = Yii::$app->request->post()['MissaoSlot'][$i];
if (!isset($modelsSlots[$id])) {
$modelsSlots[$id] = [new MissaoSlot];
}
$modelsSlots[$id] = Model::createMultiple(MissaoSlot::classname(), $modelsSlots[$id], $loadsData);
Model::loadMultiple($modelsSlots[$id], $loadsData);
$newSlotIds = array_merge($newSlotIds, ArrayHelper::getColumn($loadsData['MissaoSlot'], 'id'));
$i++;
}
$delSlotIds = array_diff($oldSlotIds, $newSlotIds);
if (! empty($delSlotIds)) MissaoSlot::deleteAll(['id' => $delSlotIds]);
$delGrupoIds = array_diff($oldGrupoIds, $newGrupoIds);
if (! empty($delGrupoIds)) MissaoGrupo::deleteAll(['id' => $delGrupoIds]);
$valid = $model->validate();
$valid = $this->validaMissao($modelsGrupos, $modelsSlots) && $valid;
if ($valid) {
if ($this->saveMissao($model, $modelsGrupos, $modelsSlots)) {
return $this->redirect(['view', 'id' => $model->id]);
}
}
}
return $this->render('update', [
'model' => $model,
'modelsGrupos' => $modelsGrupos,
'modelsSlots' => $modelsSlots,
]);
}
protected function saveMissao($modelMissao, $modelsGrupos, $modelsSlots)
{
$transaction = \Yii::$app->db->beginTransaction();
try {
if ($go = $modelMissao->save(false)) {
foreach ($modelsGrupos as $i => $modelGrupo) {
// Salva os Grupos
$modelGrupo->missao_id = $modelMissao->id;
if ($go = $modelGrupo->save(false)) {
foreach ($modelsSlots[$i] as $j => $modelSlot) {
// Salva os Slots
$modelSlot->grupo_id = $modelGrupo->id;
if (! ($go = $modelSlot->save(false))) {
$transaction->rollBack();
break;
}
}
}
}
}
if ($go) {
$transaction->commit();
}
} catch (Exception $e) {
$transaction->rollBack();
}
return $go;
}
