I generated a model which got the function attributeLabels():
public function attributeLabels()
{
return [
'column1' => 'name of column1',
'column2' => 'name of column2',
];
}
I also wrote a function in my model, which creates a SQL statement:
public function getReminders()
{
$sql = Yii::$app->db->createCommand('SELECT
[[column1]], [[column2]]
FROM {{%table}}
WHERE column1 > :value')
-> bindValue(':value', '10');
return $sql;
}
Then I created a controller with an actionIndex() function:
public function actionIndex()
{
$model = new TestObject();
$testmodels= new ActiveDataProvider([
'models' => $model->getReminders()->queryAll(),
]);
return $this->render('index', [
'testmodels' => $testmodels,
]);
Finally I created a View
GridView::widget([
'dataProvider' => $testmodels,
'layout' => '{items}{pager}',
'columns' => ['column1', column2,],
]);
For some reason, the column names of the resulting page are column1 and column2. I have tried to create a listView and got the correct names for the columns. How comes that the column names are not set by attributeLabels() in this case? I really don't want to use the label property in the gridview.
Thank you in advance!
If you just need to change the label for the gridview column you can configure you column with proper value for label
GridView::widget([
'dataProvider' => $testmodels,
'layout' => '{items}{pager}',
'columns' => [
[
'attribute'=> column1',
'label' => 'Your Lable for column 1',
],
[
'attribute'=> column2',
'label' => 'Your Lable for column 2',
],
],
]);
you can take a look at thsi for a brief guide http://www.yiiframework.com/doc-2.0/guide-output-data-widgets.html or here for ref http://www.yiiframework.com/doc-2.0/yii-grid-datacolumn.html
I would do the following:
make the base class for the TestObject be ActiveRecord
Override tableName
Simplify getReminders, make it static, and let it return Query not a Command
class TestModel extends yii\db\ActiveRecord
{
...
public static function tableName()
{
return {{%table}};
}
public static function getReminders()
{
$query = self::find()->select(['column1', 'column2'])
->where(['>', 'column1', 10]);
return $query;
}
...
}
Don't set models of the ActiveDataProvier and instead set query
'models' => TestObject::getReminders(),

I have a model File where save files of my app, it like:
class File{
public const IMAGE_TYPE = 'image';
public const AUDIO_TYPE = 'audio';
public const VIDEO_TYPE = 'video';
public const APPLICATION_TYPE = 'application';
protected $fillable = ['path', 'type', 'description', 'order', 'filable_type', 'filable_id'];
}
Suppose I have an Post model, it like:
class Post{
public function videos(){
return $this->morphMany(File::class, 'filable')
->where('type', File::VIDEO_TYPE);
}
public function images(){
return $this->morphMany(File::class, 'filable')
->where('type', File::IMAGE_TYPE);
}
}
When I get data of above relationships it's okay
But when I create a new file of post it is repetitive and easily make mistakes
$post->images()->create([
'path' => 'my-image.jpg',
'type' => File::IMAGE_TYPE,
]);
$post->videos()->create([
'path' => 'my-image.mp3',
'type' => File::VIDEO_TYPE,
]);
I want it look like:
$post->images()->create([
'path' => 'my-image.jpg',
]);
$post->videos()->create([
'path' => 'my-image.mp3',
]);
I don't need declare type per creating videos or images of a post.
How I can accomplish this!
Modal
// Change morphMany to hasMAny
public function videos()
{
return $this->hasMany(File::class, 'fileable')
->where('type', File::IMAGE_TYPE);
}
Controller
// You can do this
$vedioToCreate = $post->videos();
$vedioToCreate->path = 'my-image.mp3';
$vedioToCreate->save();
// Or you can do this
$post->videos()->create([
'path' => 'my-image.mp3',
]);
relate as below issue
Verify duplicate values on the array in Laravel5.7
I am add two fields to data base.
// database/migrations/UpdateUsersTable.php
public function up()
{
Schema::table('users', function (Blueprint $table) {
$table->string('staff_no' , 10);
$table->string('staff_code');
$table->unique(['staff_no', 'staff_code']);
});
}
I want to verify if multi column unique in my database or post array value is duplicate or not?
Here is my codes :
this is my Controller
UsersController
public function MassStore(MassStoreUserRequest $request)
{
$inputs = $request->get('users');
//mass store process
User::massStore($inputs);
return redirect()->route('admin.users.index');
}
and this is my POST data (post data($inputs) will send like as below) :
'users' => [
[
'name' => 'Ken Tse',
'email' => 'ken#gamil.com',
'password' => 'ken12ken34ken',
'staff_no' => '20191201CT',
'staff_code' => 'IT-1azz',
],
[
'name' => 'Tom Yeung',
'email' => 'tom#gamil.com',
'password' => 'tom2222gt',
'staff_no' => '20191201CT', // staff_no + staff_code is duplicate, so need trigger error
'staff_code' => 'IT-1azz',
],
]
MassStoreUserRequest
public function rules()
{
return [
'users' => ['required','array'],
'users.*.name' => ['required'],
'users.*.email' => ['required','unique:users','email', 'distinct'],
'users.*.password' => ['required','string','min:8'],
'users.*.staff_no' => ['required','size:10'],
'users.*.staff_code' => ['required','string']
// how to set verify duplicate values(staff_no,staff_code unique) in here?
];
}
You can use distinct validation rule. So your code will look like-
public function rules()
{
return [
'users' => ['required','array'],
'users.*.name' => ['required'],
'users.*.email' => ['required','unique:users','email', 'distinct'],
'users.*.password' => ['required','string','min:8'],
'users.*.staff_no' => ['required','size:10'],
'users.*.staff_code' => ['required','string', 'distinct']
];
}
Change
`'users.*.staff_code' => ['required','string']` line to
'users.*.staff_code' => ['required','string', Rule::exists('staff')->where(function ($query) {
//condition to check if staff_code and staff_no combination is unique
return $query->where('staff_code', $request->('your_key')['staff_code'])->where('staff_no', $request->('your_key')['staff_no']) ? false : true; // You may need to make a loop if you can not specify key
}),]
I solve this problem myself.
https://laravel.com/api/5.7/Illuminate/Foundation/Http/FormRequest.html#method_validationData
main point is overrides method validationData(),make value "staff_no_code" to validation data.
Here is my codes :
MassStoreUserRequest
public function rules()
{
$validate_func = function($attribute, $value, $fail) {
$user = User::where(DB::raw("CONCAT(staff_no,staff_code )", '=', $value))
->first();
if (!empty($user->id)) {
$fail(trans('validation.alreadyExists'));
}
};
return [
'users' => ['required','array'],
'users.*.name' => ['required'],
'users.*.email' => ['required','unique:users','email', 'distinct'],
'users.*.password' => ['required','string','min:8'],
'users.*.staff_no' => ['required','size:10'],
'users.*.staff_code' => ['required','string']
// 'distinct' check when working with arrays, the field under validation must not have any duplicate values.
// $validate_func check DB exist
'users.*.staff_no_code' => ['distinct',$validate_func]
];
}
//make value "staff_no_code" to validation data
protected function validationData()
{
$inputs = $this->input();
$datas = [];
foreach ($inputs as $input ) {
$input['staff_no_code'] = $input['staff_no'] . $input['staff_code'];
$datas[] = $input;
}
return $datas;
}
I have Gridview and one column value I get via http request. Is there a way to sort the table by this column?
myTableModel.php
class myTableModel extends \yii\db\ActiveRecord
{
...,
public function getExternalValue() {
$client = new Client();
return $client->createRequest()->setMethod('get')
->setUrl('http:://...')->setData(['id' => 1])->send()->content;
}
}
myTableModelSearch.php
class myTableModelSearch extends myTableModel
{
public function rules()
{
return [
[[...,'externalValue'], 'string'],
[[..., 'externalValue'], 'safe']
];
}
public $externalValue;
public function searchView($params) {
$query = SomeTable::find();
$dataProvider = new ActiveDataProvider(['query' => $query]);
$dataProvider->setSort(['attributes' => [
'externalValue' => [
'asc' => ['externalValue' => SORT_ASC],
'desc' => ['externalValue' => SORT_DESC]
]
]]);
if (!($this->load($params) && $this->validate()))
return $dataProvider;
return $dataProvider;
}
}
view.php
GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
... ,
[
'attribute' => 'externalValue',
'value' => function($item) {
return $item->externalValue;
},
]
],
]);
I also tried to add value to view simply with $item->getExternalValue() (and without public property set), but it makes no difference - when trying to sort I get database exception error SQLSTATE[42S22]: Column not found: 1054 Unknown column 'externalValue' in 'order clause'. How could I trick gridview, to make it sort my table by externalValue column?
You're using yii\data\ActiveDataProvider which uses an instance of ActiveQuery to find its data.
Try using yii\data\ArrayDataProvider, or extend yii\data\ActiveDataProvider to allow a second source for your data.
Additionally, you have to implement a sort function that can sort using your attribute.

I'm create a new table(s) in my Yii application thats going to be used as a relational table, just storing IDs, it's really simple, but i cannot manage to actually get any information passed through from the model, even though the IDs match. Can anyone see where i'm going wrong?
User Model (has many relations, but i've just included the one im having a problem with)
public function relations() {
return array(
'onsiteGroup' => array(self::HAS_MANY, 'EventAttendeesGroups', 'user_id'),

}
EventAttendeeGroups Model
class EventAttendeesGroups extends CActiveRecord

My Data is correct, the user id exists in the user table and in the EventAttendeeGroups table, yet if try the following in the user view gridview table, i get 'Not Set'
array(
'name' => 'group_id',
'type' => 'raw',
'value' => $model->onsiteGroup->group_id,
),
Can anyone see where i'm going wrong???
Are you getting an error? What is it outputting? Are you trying to render CGridView or what, and if yes is it formed?
One thought, are you sure
$model->onsiteGroup->group_id
is the object name and not
$model->onsiteGroupName->group_id
Just a thought.
Eselect2 is the extension am using and myADropDown() fetches the data and displays but then my need is concatenate two or more columns in the dropdown
model1 view
<?php $this->widget('ext.select2.ESelect2', array(
'name' => 'id',
'model' => $model,
'options' => array(
'placeholder' => $model->getAttributeLabel('id'),
),
'data' => $model->myADropDown(),
));?>
model1
public function getConcatened()
{
return $this->name.' '.$this->locate.' '.$this->rating;
}
public function myADropDown()
{
$vid=Yii::app()->SESSION['vid'];
$gid=Model2::model()->xyz($vid);
$list=CHtml::listData($gid,'id','concatened');
return $list;
}
// id is fk in another tbl
in the dropdownlist my need is name ,location,rating for each person , am unable to do so
Please Let me know how do i achieve it
For concatenating the table fields in listdata, Please check this Yii forum answer:
Link
As per the link suggestion, you need to add a function in model to get concatenated string.
public function __get($key){
$action = 'get'.str_replace(' ','',ucwords(str_replace('_',' ',$key)));
if(method_exists($this, $action)) return $this->$action();
return parent::__get($key);
}
