Yii2 Dynamic Form update Action is not working - yii2

Question

I like to explain my problem clearly,
Am using wbraganca/yii2-dynamicform
Here create action is working perfectly, but in update action
In the code which i marked, i don't know what i need to do, i dont have such field (addresses) in customer table. am stuck on that.
suppose if i create a variable in model like public $addressess, it makes me the reload the table again, and that cause while update the same form, data's getting reload and form viewing as empty without empty,
if create a function on that name, i don't know what to write on that..
Am simply using code like this
public function getaddressess()
{
}
Create Action Code
public function actionCreate()
{
$modelCustomer = new Customer;
$modelsAddress = [new Address];
if ($modelCustomer->load(Yii::$app->request->post())) {
$modelsAddress = Model::createMultiple(Address::classname());
Model::loadMultiple($modelsAddress, Yii::$app->request->post());
// ajax validation
if (Yii::$app->request->isAjax) {
Yii::$app->response->format = Response::FORMAT_JSON;
return ArrayHelper::merge(
ActiveForm::validateMultiple($modelsAddress),
ActiveForm::validate($modelCustomer)
);
}
// validate all models
$valid = $modelCustomer->validate();
$valid = Model::validateMultiple($modelsAddress) && $valid;
if ($valid) {
$transaction = \Yii::$app->db->beginTransaction();
try {
if ($flag = $modelCustomer->save(false)) {
foreach ($modelsAddress as $modelAddress) {
$modelAddress->customer_id = $modelCustomer->id;
if (! ($flag = $modelAddress->save(false))) {
$transaction->rollBack();
break;
}
}
}
if ($flag) {
$transaction->commit();
return $this->redirect(['view', 'id' => $modelCustomer->id]);
}
} catch (Exception $e) {
$transaction->rollBack();
}
}
}
return $this->render('create', [
'modelCustomer' => $modelCustomer,
'modelsAddress' => (empty($modelsAddress)) ? [new Address] : $modelsAddress
]);
}
Help me to sort out this problem

Answer 1

$modelsAddress=$modelCustomer->addresses in that example mean array of related Address() instances
public function actionCreate()
{
$modelCustomer = new Customer;
$modelsAddress = $this->getaddressess($modelCustomer->id);
//...................
}
public function getaddressess($id)
{
$model = Address::find()->where(['id' => $id])->all();
return $model;
}

Answer 2

from
public function getaddressess($id)
{
$model = Address::find()->where(['id' => $id])->all();
return $model;
}
Shared above you will also need to add
on your Update view file :
'model' => $model,
'modelsAddress'=>$modelsAddress,
Hope this helps. It worked for me

Answer 3

It should be getAddresses() instead of getaddresses() (although both could work, I'd go with the first one to meet conventions). Or you could set a public $addresses if you don't need extra encapsulation.
suppose if i create a variable in model like public $addressess, it makes me the reload the table again, and that cause while update the same form, data's getting reload and form viewing as empty without empty,
I think you have a validation issue - no validator to mark the field as safe and you see it as empty after posting.
Add public $addresses to your Customer model.
Add "addresses" to your validation rules as safe (or more appropriate validator). This way after posting the form, it probably won't render empty.

Answer 4

This line code ---> $modelsAddress = $modelCustomer->addresses;
is get from model for customer at line ---> public function getAddresses()
this public function line code is code for get array related table from active record method on yii2.

Answer 5

$modelCustomer->addresses the word addresses should come from the $modelCustomer model you must have a relationship to the other table where you add the multiple values. In my example described in the video I have two tables po table and po_items table po_items table has foreign key of po_id. So when you make the Models using gii you will get a relationship in the model that is what you have to use instead of the addresses.
the relationship according my database should be - poItems you will see this at line 14

Answer 6

Add this to Customer Model
public function getAddresses(){
return $this->hasMany(Address::className(), ['id' => 'id']);
}

Answer 7

enter image description hereIn Po.php models:
public function getPoItems()
{
return $this->hasMany(PoItem::className(), ['po_id' => 'id']);
}
In PoController.php
public function actionUpdate($id)
{
$model = $this->findModel($id);
//$modelsPoItem = [new PoItem];
$modelsPoItem = $model->poItems;
if ($model->load(Yii::$app->request->post()) && $model->save())
{
$oldIDs = ArrayHelper::map($modelsPoItem, 'id', 'id');
$modelsPoItem = Model::createMultiple(PoItem::classname(), $modelsPoItem);
Model::loadMultiple($modelsPoItem, Yii::$app->request->post());
$deletedIDs = array_diff($oldIDs, array_filter(ArrayHelper::map($modelsPoItem, 'id', 'id')));
// validate all models
$valid = $model->validate();
$valid = Model::validateMultiple($modelsPoItem) && $valid;
if ($valid) {
$transaction = \Yii::$app->db->beginTransaction();
try {
if ($flag = $model->save(false)) {
if (! empty($deletedIDs))
{
PoItem::deleteAll(['id' => $deletedIDs]);
}
foreach ($modelsPoItem as $modelPoItem)
{
$modelPoItem->po_id = $model->id;
if (! ($flag = $modelPoItem->save(false))) {
$transaction->rollBack();
break;
}
}
}
if ($flag) {
$transaction->commit();
return $this->redirect(['view', 'id' => $model->id]);
}
} catch (Exception $e) {
$transaction->rollBack();
}
}
}
return $this->render('update', [
'model' => $model,
'modelsPoItem' => (empty($modelsPoItem)) ? [new PoItem] : $modelsPoItem
]);
}
