I have following tables
notice[id, type],
property[id, type],
property_value[id, notice_id, property_id, value].
Each notice has own properties specified by it's type. I need to make a filter by several properties simultaniously, and issue is how to specify which property shoud have a specified value?
class Notice extends CActiveRecord{
/** #var array property_id=>value from $_GET*/
public $searchParams= array();
public function search() {
$criteria = new CDbCriteria;
// $criteria->together = true;
$criteria->compare('t.type', $this->type);
foreach ( $searchParams as $property_id => $value) {
/// What should i write here?
/// $criteria->compare('propertyValues.id', $id);
/// $criteria->compare('propertyValues.value', $value);
}
}
}
Ps: Found this and this but i need specify params...
As i found this issue is around a classic EAV model (Entity–attribute–value). So for temporary (but no finest) solution i join value's table multiply times for every parameter:
public function search() {
foreach ($properties as $id => $value) {
$joinAlias = 'p_' . $property->id;
$join = "\nLEFT JOIN property_value as $joinAlias ON t.id= {$joinAlias}.notice_id AND {$joinAlias}.property_id='{$property_id}' ";
$criteria->compare("{$joinAlias}.value", $value);
$criteria->join .= $join;
}
}

I have a query in existing application now i need to update query in eloquent way i have the following structure of my relationships how can i write the following query in eloquent way
Controller Query that i want to change in eloquent way
foreach ($data['Divisions'] as $sections) {
$SecQry1 = "SELECT sections.id, sections.division_id, sections.code, sections.name ,specifications.description
from specifications inner JOIN sections on specifications.section_id=sections.id where specifications.status='active'
AND specifications.manufacturer_id = $user->id AND sections.division_id=" . $sections->id . " group by sections.id";
$SectionsDivision1 = DB::select($SecQry1);
foreach ($SectionsDivision1 as $key => $selectionDiv) {
array_push($selectionDiv_array1, $selectionDiv);
}
}
class Specification extends Model {
protected $table = 'specifications';
public function section()
{
return $this->belongsTo('App\Section');
}
}
class Section extends Model {
protected $table = 'sections';
public function specifications()
{
return $this->hasMany('App\Specification', 'section_id');
}
public function division()
{
return $this->belongsTo('App\Division');
}
}
class Division extends Model {
protected $table = 'divisions';
protected $fillable = array('name', 'description', 'code','status');
public function sections()
{
return $this->hasMany('App\Section', 'division_id');
}
}
0 => {#1063 ▼

}
]
You dont need relations for this specific query, you could use Laravel Eloquent with join like so:
$SectionsDivision1 = Specification::join('sections', 'specifications.section_id', '=', 'sections.id')
->where([
'specifications.status' => 'active',
'specifications.manufacturer_id' => $user->id,
'sections.division_id' => $sections->id
])->select('sections.id', 'sections.division_id', 'sections.code', 'sections.name', 'specifications.description')
->groupBy('sections.id');
I hope it helps
I'm trying to learn cakephp 3 and the ORM functions, wicht is great so far. But know I'm comming to a point on wich I'm not certain how I can aproach it in the best way, so I was hoping that somebody can tell what is the best way.
I'm using the query builder to load one or more products. In the data that's loaded I have one field called price. This is the main price of the product, but there can be an optional discount for an user. I know wich user is logged in to the system so I have an variabele witch contains his discount, for example 1.20 (=20%).
After the query has been fired I could do an foreach and recalculate the price before sending is to the view, but because of the query builder function I suspect that I can do it there before I fired the query.
Below an example where an search is done on input name. The field price is now standard, but should be recalculated with the discount.This could be an foreacht example:
$price = round((($price/$User->discount)-$shipping),2);
SearchController:
public function search()
{
if ($this->request->is('post')) {
//$this->request->data);
$options = array();
$options['query'] = $this->request->data['Search']['query'];
$products = TableRegistry::get('Products');
$query = $products->find('search', $options);
$number = $query->count();
$products = $query->All();
$this->set(compact('products'));
$this->set('number_of_results',$number);
}
The ProductsTable:
public function findSearch(Query $query, array $options)
{
$query
->where([
'name LIKE' => '%'.$options['query'].'%',
"active" => 1
])
->contain(['ProductsImages'])
->select(['id','name','price','delivery_time','ProductsImages.image_url'])
;
return $query;
}
Is there an way to implement this recalculation in the query builder? I tried to find some info on the web but there isn't much information yet about the ORM options. I was thinking about maybe ->combine. Hopefully someone wants to put me in the right direction.
Thanks in forward.
Changed the controller function to:
public function search()
{
if ($this->request->is('post')) {
$options = array();
$options['query'] = $this->request->data['Search']['query'];
$discount = 2;
$products = TableRegistry::get('Products');
$query = $products
->find('search', $options);
$query->formatResults(function (\Cake\Datasource\ResultSetInterface $products) {
return $products->map(function ($row) {
$row['price'] = ($row['price'] + 10);
return $row;
});
});
$number = $query->count();
$products = $query->All();
$this->set(compact('products'));
$this->set('number_of_results',$number);
}
}
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.
I have several models with relations and what I am trying to do is to search the fields with the aliases I provide in DetailView. It looks like this
<?php $this->widget('bootstrap.widgets.BootGridView',array(
'id'=>'operations-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
'operationType.name:raw:Operation',
'creation_date:datetime',
'modification_date:datetime',
'ammount_usd:raw:Ammount',
'currency.short',
/*
'client_id',
'organization_id',
*/
array(
'class'=>'bootstrap.widgets.BootButtonColumn',
),
),
)); ?>
And what I want is to be able to search through rows using the aliases for columns like currency.short. What is a correct approach to do that? Tried to modify the search() method like this..but I think I'm missing something.
public function search()
{
// Warning: Please modify the following code to remove attributes that
// should not be searched.
$criteria=new CDbCriteria;
$criteria->compare('creation_date',$this->creation_date,true);
$criteria->compare('modification_date',$this->modification_date,true);
$criteria->compare('ammount',$this->ammount,true);
$criteria->compare('ammount_usd',$this->ammount_usd,true);
$criteria->compare('currency_id',$this->currency_id);
$criteria->compare('operation_type',operationType::model()->name);
$criteria->compare('client_id',$this->client_id);
$criteria->compare('organization_id',$this->organization_id);
$criteria->compare('comment',$this->comment);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
Thanks.
You have to create a virtual field for that property. For example in your main model:
private _currencyshort = null;
public function setCurrencyshort($value) {
$this->_currencyshort = $value;
}
public function getCurrencyshort() {
if ($this->_currencyshort === null && $this->currency != null)
{
$this->_currencyshort = $this->currency->short
}
return $this->_currencyshort;
}
public function search() {
$criteria=new CDbCriteria;
$criteria->with = array('currency'); // add more elements to array if you want to search by more relations
$criteria->compare('currency.short',$this->currencyshort);
// You can also add this field to your sorting criteria
// ... etc
}
Also you have to add currencyshort into your rules() method of main model to the line where it states 'on'=>'search', for example:
array('currencyshort', 'safe', 'on'=>'search'),
Then in columns instead of currency.short you can put currencyshort and it will work with filters, sorting and etc.
