I'm trying to send a POST request with a data set like this:
[
{
"Course_Code":"CIS341",
"Start_Date":"2020-08-22",
"End_Date":"2020-12-02",
"CRN":345627,
"CWID":"C38475920",
"Date_Registered":"2020-04-02"
},
{
"Course_Code":"CIS341",
"Start_Date":"2020-08-22",
"End_Date":"2020-12-02",
"CRN":456392,
"CWID":"C38475920",
"Date_Registered":"2020-04-02"
},
{
"Course_Code":"CIS341",
"Start_Date":"2020-08-22",
"End_Date":"2020-12-02",
"CRN":562940,
"CWID":"C38475920",
"Date_Registered":"2020-04-02"
}
]
But I only want to insert the CRN, CWID, Date_Registered from each of those objects into my final_schedule table:
protected $table ="final_schedule";
public $timestamps = false;
protected $fillable = [
'CWID',
'CRN',
'Date_Registered'
];
Here is the insert function I'm using:
public function insert(Request $request){
$CWID->CWID = $request->input('CWID');
$CRN->CRN = $request->input('CRN');
$Date_Registered->Date_Registered = $request->input('Date_Registered');
$items = array('CWID'=>$CWID, 'CRN'=>$CRN, 'Date_Registered'=>$Date_Registered);
finalScheduleModel::insert($items);
}
When I test this insert function in postman it gives the error:
ErrorException: Creating default object from empty value in file
And the line the error is pointing to is the first line of the function
$CWID->CWID = $request->input('CWID');
I tried writing this function many different ways, but I keep getting errors along the same lines. It never reads any of the data being sent over. It might say something like trying to insert values CWID, CRN, Date_Registered (?,?,?) into final_schedule.
Try this see if this works for you.
public function insert(Request $request){
$array = [];
foreach (request()->all() as $value) {
array_push($array, ['CWID' => $value['CWID'], 'CRN' => $value['CRN'], 'Date_Registered' => $value['Date_Registered']]);
}
DB::table('final_schedule')->insert($array);
}

I'm migrating a solution from asp net to asp net core. When I tested this method
[HttpPut, Route("SearchPrices")]
public dynamic SearchPrices(dynamic data)
{
var list = from ma in db.Materials
select new
{
ma.MaterialID,
ma.MaterialTypeID,
ma.StatusID,
ma.Horsepower,
ma.MaterialPrice
};
list = list.OrderBy(s => s.MaterialID);
string filterString = data.filterString;
if (!string.IsNullOrEmpty(filterString))
{
list = list.Where(ma => new[] {
ma.MaterialID,
ma.MaterialPrice.ToString(),
ma.MaterialTypeID
}.Any(c => c.Contains(filterString)));
}
dynamic sort = data.sort;
string column = sort.column;
if (!string.IsNullOrEmpty(column))
{
bool reverse = sort.reverse;
list = list.OrderByColumn(column, reverse);
}
return FilterByColumn(list, data);
}
I receive a parameter with something like
ValueKind = Object : "{"filterString":"","options":[],"skipNumber":0,"takeNumber":50,"sort":{"column":"","reverse":false}}"
In which I cant make it work like it used to before, it throws a error when it tries to resolve "Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: ''System.Text.Json.JsonElement' does not contain a definition for 'filterString''".
I've already tried some solutions to deserialize, but they didn't work.
How to validate two dimensional array in Yii2.
passenger[0][name] = bell
passenger[0][email] = myemail#test.com
passenger[1][name] = carson123
passenger[1][email] = carson###test.com
how to validate the name and email in this array
Thanks
Probably the most clean solution for validating 2-dimensional array is treating this as array of models. So each array with set of email and name data should be validated separately.
class Passenger extends ActiveRecord {
public function rules() {
return [
[['email', 'name'], 'required'],
[['email'], 'email'],
];
}
}
class PassengersForm extends Model {
/**
* #var Passenger[]
*/
private $passengersModels = [];
public function loadPassengersData($passengersData) {
$this->passengersModels = [];
foreach ($passengersData as $passengerData) {
$model = new Passenger();
$model->setAttributes($passengerData);
$this->passengersModels[] = $model;
}
return !empty($this->passengers);
}
public function validatePassengers() {
foreach ($this->passengersModels as $passenger) {
if (!$passenger->validate()) {
$this->addErrors($passenger->getErrors());
return false;
}
}
return true;
}
}
And in controller:
$model = new PassengersForm();
$model->loadPassengersData(\Yii::$app->request->post('passenger', []));
$isValid = $model->validatePassengers();
You may also use DynamicModel instead of creating Passanger model if you're using it only for validation.
Alternatively you could just create your own validator and use it for each element of array:
public function rules() {
return [
[['passengers'], 'each', 'rule' => [PassengerDataValidator::class]],
];
}
You may also want to read Collecting tabular input section in guide (unfortunately it is still incomplete).
I have tested it with 2 methods:
The first:
class ProjectsController extends ControllerBase
{
public function indexAction()
{
$row = array();
$projects = Projects::find();
foreach ($projects as $project) {
foreach($project->employees as $employee){
echo "Employee: " . $employee->name;
}
}
exit;
}
}
Output:
Employee: Admin
The second:
class ProjectsController extends ControllerBase
{
public function indexAction()
{
$row = array();
$projects = Projects::find();
$projects = $projects->toArray();
foreach ($projects as $project) {
foreach($project["employees"] as $employee){
echo $employee->name;
}
}
exit;
}
}
Output:
Notice: Undefined index: employees in app/controllers/ProjectsController.php on line 10
When converting the resultset to array the relationships aren't added to the array, is there a workaround to add it to the array?
The reason I converted the resultset to an array is to edit results for example calculating progress or something like that, without saving it to the database.
Things like this:
foreach($projects as &$project){
//count all the todos.
$todos = Todos::find("project_id = '".$project["id"]."'");
$numberOfTodos = $todos->count();
//count all the todos that are done.
$todos = Todos::find("project_id = '".$project["id"]."' AND status_id = 9");
$numberOfDoneTodos = $todos->count();
$project["percentageDone"] = ($numberOfDoneTodos / $numberOfTodos) * 100;
var_dump($row);exit;
}
$this->view->setVar("projects",$projects);
So I don't have to do calculations on the view side and only have to output it
Yes, when you convert a result set to an array only scalar values are converted.
But for adding a calculated property to your model there's no need to convert it to an array, you can change or create new properties as you wish and it will only be saved to the database when you call for example $project->save() and just properties that match a column name will be stored in the database.
For adding calculated properties I'd recommend you to use the event afterFetch that gets fired for each model retrieved from the database:
class Projects extends \Phalcon\Mvc\Model
{
...
public function afterFetch()
{
//Adds a calculated property when a project is retrieved from the database
$totalTodos = Todos::count("project_id = $this->id");
$completeTodos = Todos::count("project_id = $this->id AND status_id = 9");
$this->percentageDone = round(($completeTodos / $totalTodos) * 100, 2);
}
}
I'm new to Yii and I have a table 'Student' with fields like 'stdStudentId', 'stdName', etc.
I'm making API, so this data should be returned in JSON. Now, because I want field names in JSON to just be like 'id', 'name', and I don't want all fields returned, i made a method in the model:
public function APIfindByPk($id){
$student = $this->findByPk($id);
return array(
'id'=>$student->stdStudentId,
'name'=>$student->stdName,
'school'=>$student->stdSchool
);
}
The problem is, stdSchool is a relation and in this situation, $student->stdSchool returns array with fields like schSchoolId, schName, etc. I don't want fields to be named like that in JSON, and also I don't want all the fields from School returned and I would like to add some fields of my own. Is there a way to do this in Yii, or I'll have to do it manually by writing methods like this?
I have been looking for the same thing. There is a great php lib named Fractal letting you achieve it: http://fractal.thephpleague.com/
To explain briefly the lib, for each of your models you create a Transformer that will be doing the mapping between your model attributes and the ones that need to be exposed using the api.
class BookTransformer extends Fractal\TransformerAbstract
{
public function transform(Book $book)
{
return [
'id' => (int) $book->id,
'title' => $book->title,
'year' => $book->yr,
];
}
}
In the transformer you can also set the relation that this model have :
class BookTransformer extends TransformerAbstract
{
/**
* List of resources relations that can be used
*
* #var array
*/
protected $availableEmbeds = [
'author'
];
/**
* Turn this item object into a generic array
*
* #return array
*/
public function transform(Book $book)
{
return [
'id' => (int) $book->id,
'title' => $book->title,
'year' => $book->yr,
];
}
/**
* Here we are embeding the author of the book
* using it's own transformer
*/
public function embedAuthor(Book $book)
{
$author = $book->author;
return $this->item($author, new AuthorTransformer);
}
}
So at the end you will call
$fractal = new Fractal\Manager();
$resource = new Fractal\Resource\Collection($books, new BookTransformer);
$json = $fractal->createData($resource)->toJson();
It's not easy to describe all the potential of fractal in one answer but you really should give it a try.
I'm using it along with Yii so if you have some question don't hesitate!
Since you are getting the values from the database using Yii active record, ask the database to use column aliases.
Normal SQL would be something like the following :
SELECT id AS Student_Number, name AS Student_Name, school AS School_Attending FROM student;
In Yii, you can apply Criteria to the findByPK() function. See here for reference : http://www.yiiframework.com/doc/api/1.1/CActiveRecord#findByPk-detail
$criteria = new CDbCriteria();
$criteria->select = 'id AS Student_Number';
$student = Student::model()->findByPk($id, $criteria);
Note that in order to use a column alias like that, you will have to define a virtual attribute Student_Number in your Student{} model.
Override the populateRecord() function of ActiveRecord can achieve this!
My DishType has 5 properties and override the populateRecord function Yii would invoke this when records fetched from db.
My code is here!
class DishType extends ActiveRecord
{
public $id;
public $name;
public $sort;
public $createTime;
public $updateTime;
public static function populateRecord($record, $row)
{
$pattern = ['id' => 'id', 'name' => 'name', 'sort' => 'sort', 'created_at' => 'createTime', 'updated_at' => 'updateTime'];
$columns = static::getTableSchema()->columns;
foreach ($row as $name => $value) {
$propertyName = $pattern[$name];
if (isset($pattern[$name]) && isset($columns[$name])) {
$record[$propertyName] = $columns[$name]->phpTypecast($value);
}
}
parent::populateRecord($record, $row);
}
}
I am working with options, to add some additional info like image. and I saved this data to my own table with option_type_id and option_id. now on frontend I would like to join my own table data to default options. so these options come with image info.
$_option->getValues()
this function returns option data, now I have to reach the implementation of this function where it generate the query so I could add join to retrieve my own data with.
I dont see a clean way to do this.
Here is a dirty way:
RewriteMage_Catalog_Model_Resource_Product_Option and add this function below.
Modify it with you join. however the join to you table would then be done for every product option. You will need to check for somekind of a flag and only add your join if this flag is set.
protected function _getLoadSelect($field, $value, $object)
{
$select = parent::_getLoadSelect($field, $value, $object);
if("do your check here"){
$select->join('your table')
}
return $select;
}
Here is what i got success from.
i overridden the resource collection of product
class MYC_COPSwatch_Model_Resource_Product_Option_Collection extends Mage_Catalog_Model_Resource_Product_Option_Collection{
public function addValuesToResult($storeId = null)
{
if ($storeId === null) {
$storeId = Mage::app()->getStore()->getId();
}
$optionIds = array();
foreach ($this as $option) {
$optionIds[] = $option->getId();
}
if (!empty($optionIds)) {
/** #var $values Mage_Catalog_Model_Option_Value_Collection */
$values = Mage::getModel('catalog/product_option_value')
->getCollection()
->addTitleToResult($storeId)
->addPriceToResult($storeId)
->addSwatchToResult($storeId) //USED Join in this function
->setOrder('sort_order', self::SORT_ORDER_ASC)
->setOrder('title', self::SORT_ORDER_ASC);
foreach ($values as $value) {
$optionId = $value->getOptionId();
if($this->getItemById($optionId)) {
$this->getItemById($optionId)->addValue($value);
$value->setOption($this->getItemById($optionId));
}
}
}
return $this;
}
might be save time for someone.
