Yii2 grid updating with editable field - php

Question

I followed the post on setting up an editable field in a grid here http://webtips.krajee.com/setup-editable-column-grid-view-manipulate-records/
Everything seems to work - I click on the field, change it's value and it shows the updated value in the grid. However - next time I refresh, the value reverts to the original value.
I've done a little debugging, and it would appear that the save in the controller is failing.
My table has a two key fields (key1 and key2) and a value field. I am trying to update this value field.
My view code is as follows:
$gridColumns = [
'AnotherField',
[
'class' => 'kartik\grid\EditableColumn',
'attribute'=>'value',
'label' => 'some value',
'editableOptions'=> [
'header' => 'profile',
'format' => Editable::FORMAT_BUTTON,
]
];
...
...
<?= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => $gridColumns
]) ?>
and the controller code is as follows:
<snip>
//default code from gii-generated controller
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
// orig post said to use this: $dataProvider = $searchModel->search(Yii::$app->request->getQueryParams());
// Validate if there is an editable input saved via AJAX
if (Yii::$app->request->post('hasEditable')) {
$model = new MyTable;
$post = [];
$posted = current($_POST['MyTable']);
$post['MyTable'] = $posted;
// Load model like any single model validation
if ($model->load($post)) {
// When doing $result = $model->save(); I get a return value of false
$model->save();
$out = Json::encode(['output'=>$output, 'message'=>'']);
}
// Return AJAX JSON encoded response and exit
echo $out;
return;
}
// Non-AJAX - render the grid by default
</snip>
How does the controller know which record to update as I am only passing in the 'value' field, not the keys?
Do I somehow need to add these key1 and key2 fields to the view within the editable widget in order to get these values passed to the controller (so that the load and save know which record to update) or is there some other way that the controller handles this?

Answer 1

In the example on this page http://demos.krajee.com/grid-demo (you can see the column definition too) you can see with firebug that the following values are sent:
Book[5][buy_amount] 1
_csrf MEQ0NnEzNjFhd2dBB2wBCHN0cGVCA3lfZHF1TDReRlAAcQNUPUFjBQ==
editableIndex 5
editableKey 6
hasEditable 1
I believe the 5 in Book[5] is probably matching the index of the record.
This part does that from what I see
$post = [];
$posted = current($_POST['Book']);
$post['Book'] = $posted;
I have never used the widget so I might be wrong.

Answer 2

I have found the solution with some experimentation. I had to unserialize the $editableKey value and extract my key field values from it. I then call 'findModel' to load in the record to be updated.
The updated controller code is as follows:
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
// Validate if there is an editable input saved via AJAX
if (Yii::$app->request->post('hasEditable')) {
$keys = unserialize(Yii::$app->request->post('editableKey'));
$model = $this->findModel($keys['key1'], $keys['key2']);
// Store a default JSON response as desired by editable
$out = Json::encode(['output'=>'', 'message'=>'']);
// Fetch the first entry in posted data (there should only be one
// entry anyway in this array for an editable submission)
$values = current($_POST['MyTable']);
// Load model like any single model validation
if ($model->key1) {
// Update the Profile with the new value passed in
$model->value = $values['value'];
$model->save();
...
Thanks for the advice

I was also looking for a solution of updating table using Editable column. Looking at the ajax post I got similar like this output:
Book[5][buy_amount] 1
_csrf MEQ0NnEzNjFhd2dBB2wBCHN0cGVCA3lfZHF1TDReRlAAcQNUPUFjBQ==
editableIndex 5
editableKey 6
hasEditable 1
Here I found the value of editableKey is the value of id of the table.
So to update specific row on gridview column I used the editableKey and update based on it.
In controller :
if (Yii::$app->request->post('hasEditable')) {
$_id=$_POST['editableKey'];
$model = $this->findModel($_id);
$post = [];
$posted = current($_POST['MyTable']);
$post['MyTable'] = $posted;
// Load model like any single model validation
if ($model->load($post)) {
// When doing $result = $model->save(); I get a return value of false
$model->save();
if (isset($posted['buy_amount']))
{
$output = $model->buy_amount;
}
$out = Json::encode(['output'=>$output, 'message'=>'']);
}
// Return AJAX JSON encoded response and exit
echo $out;
return;
}
I just get the post data using $_id=$_POST['editableKey'];
and set my $model as $model = $this->findModel($_id);
now you can update multiple editable column just adding condition like this
if (isset($posted['buy_amount']))
{
$output = $model->buy_amount;
}
Thanks!
