I have 4 tables of order payments user and profiles. Payments has a belongs_to relation with order. Order has a belongs_to relation with user, and user has_many profiles.
While displaying payments in cgridview I need to display the firstname and lastname of user stored in profile.
I tried using:
$data->order->user->profiles->firstname;
Also tried to add parameter firstname to the model class of Payment and tried to create the setter method as:
public function getFirstname(){
if ($this->_firstname=== null && $this->order !== null) {
$this->_firstname = $this->order->user->profiles->firstname;
}
return $this->_firstname ;
}
public function setFirstname($value){
$this->_firstname = $value ;
}
But I have not been able to get the desired result.
Edit: the search method has the following code:
public function search() {
$criteria = new CDbCriteria;
$criteria->with = array('order.user.profiles') ;
. . . .
$criteria->compare('firstname', $this->_firstname, true);
. . . .
return new CActiveDataProvider($this, array(
'criteria' => $criteria,
));
}
I would suggest using the "through" relation as it makes life easier. All you have to do is, goto your "payments" model and add the following relations,
public function relations()
{
return array(
'order' => array(self::BELONGS_TO, 'Orders', 'order_id'),
'user'=>array(
self::BELONGS_TO,'User',array('user_id'=>'id'),'through'=>'order'
),
'profiles'=>array(
self::HAS_MANY,'Profile',array('id'=>'user_id'),'through'=>'user'
),
);
}
and in the grid you can access the first_name by using,
$data->profiles[0]->firstname
try this in model:
public function getFirstname(){
return $this->order->user->profiles->firstname;
}
and in the grid:
$data->firstname;

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 have problem in CGrid while on sorting a relational data using relational model in `` page.
Briefly my scenario:
I have a user model: Entities=> id,username
And a profile Model: Entities=> id, firstname,lastname, user_id,etc..
I want to list profile model and username from user model in CGrid, so that sorting and searching perms well. In my case sorting username is done by user_id not by username. I want to search it by username,so i do the following,
My Controller Action:
$model = new Profile('search');
$model -> unsetAttributes();// clear any default values
if (isset($_GET['Profile']))
$model -> attributes = $_GET['Profile'];
$this -> render('MyPage', array('model' => $model ));
My Model Relation:
public function relations() {
// NOTE: you may need to adjust the relation name and the related
// class name the relations automatically generated below.
return array(
'user' => array(self::BELONGS_TO, 'user', 'user_id'),);
}
Model Rules:
array( 'xxx,yyy,user_name', 'safe', 'on'=>'search' ),
And model search function
if(!empty($this->user_id)){
$criteria->with='user';
$criteria->order = ::app()->request->getParam('sort');// 'username ASC'
}
$criteria -> compare('user.username', $this->user_id, true);
My
$this->widget('zii.widgets.grid.CGrid', array(
'id'=>'profile-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
array('name'=>'user_id',
'header'=>User::model()->getAttributeLabel('username'),
'value' =>'$data->getRelated(\'user\')->username',
'type'=>'raw',
'htmlOptions'=>array('style'=>'text-align: center'),),
---------------
During sorting,sorting works perfectly but sorting is done on the basis of user_id not by username. Anything that i am missing to do so. Please suggest.
Reference:Here (I also tried as by declaring a public variable as suggesting in the link but bot workingg.)
Edit: After Issue Fixed.
Thanks for this link too.
Well, the wiki page you found is really a good start...
Here is an alternative way for doing this :
In your Profile model :
// private username attribute, will be used on search
private $_username;
public function rules()
{
return array(
// .....
array('username', 'safe', 'on'=>'search'),
// .....
);
}
public function getUsername()
{
// return private attribute on search
if ($this->scenario=='search')
return $this->_username;
// else return username
if (isset($this->user_id)) && is_object($this->user))
return $this->user->username;
}
public function setUsername($value)
{
// set private attribute for search
$this->_username = $value;
}
public function search()
{
// .....
$criteria->with = 'user';
$criteria->compare('user.username', $this->username, true);
// .....
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'sort'=>array(
'attributes'=>array(
'username'=>array('asc'=>'user.username', 'desc'=>'user.username DESC'),
'*',
),
),
));
}
And in your view you should simply try :
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'profile-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
// .....
'username',
// .....
),
);
i try to using bigcommerce API to retrieves a specific shipment in an order.
Here is my code
$Orders = BigCommerce_Api::getOrder(100);
$order_shipments = Bigcommerce_Api::getCollection('/orders/'.$Orders->id. '/shipments/'. 1, 'Shipment');
but it shows a warning:
array_map(): Argument #2 should be an array in
C:\xampp\htdocs\comm\Bigcommerce\Api.php on line 220
Can anyone help me with this?
Already solve this got some coding error in the Big Commerce API
in Resources.php update code
class Bigcommerce_Api_Shipment extends Bigcommerce_Api_Resource {
protected $ignoreOnCreate = array(
'id',
'order_id',
'date_created',
'customer_id',
'shipping_method',
);
protected $ignoreOnUpdate = array(
'id',
'order_id',
'date_created',
'customer_id',
'shipping_method',
'items',
'billing_address',
'shipping_address',
);
public function create()
{
return Bigcommerce_Api::createResource('/orders/' . $this->order_id . '/shipments', $this->getCreateFields());
}
public function update()
{
return Bigcommerce_Api::updateResource('/orders/' . $this->order_id . '/shipments/' . $this->id, $this->getUpdateFields());
}
}
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.
I'm trying to retrieve information from a database using Kohana ORM.
There are two relevant tables in my database:
branches
id smallint
parent_id smallint
name varchar
active int
branches_options
id mediumint
branche_id smallint
name varchar
customer_id int
With the following code I want to retrieve the information from the branches_options table
` $branchesOptions[] = ORM::factory('branches_option')
->where('branche_id', '=', $subBranche)
->join('branches', 'LEFT')->on('branches.id', '=', 'branches_options.branche_id')
->order_by('name')
->find_all()
->as_array();`
Now I want to see the value of branches.name in the result set, but I'm not sure how to do this in Kohana.
The code of the models is:
`class Model_Branche extends ORM
{
protected $_has_many = array(
"options" => array('model' => 'branches_option'),
"adwords_templates" => array ('model' => 'adwords_template')
);
public $result = array();`
and
`class Model_Branches_option extends ORM
{
protected $_has_many = array (
"keywords" => array('model' => 'branches_options_keyword')
);
protected $_has_and_belongs_to = array (
"adwords_templates" => array (
"model" => "adwords_template",
"through" => "branches_options_templates"
)
);
protected $_belongs_to = array ( "branche" => array () );`
Can this be done and if so, how?
You need to make some important changes to you models for this to work properly:
class Model_Branche extends ORM
{
protected $_has_many = array(
'options' => array(
'model' => 'branches_option',
'foreign_key' => 'branche_id'
)
);
}
And the Branches_Option model (it should be in model/branche/ folder):
class Model_Branches_Option extends ORM
{
protected $_belongs_to = array(
'branche' => array()
);
}
Now you can do something like that:
$options = ORM::factory('branche', $branche_id)
->options
->find_all();
foreach ($options as $option)
{
$branche_active = $option->branche->active;
$branche_name = $option->branch->name;
$option_name = $option->name;
}
One of the most important changes here is that we specify the foreign_key option in the $_has_many relationship. Since the ORM is using the Kohana Inflector helper it might not recognize it automatically (branches in singular form is branch and not branche).
If it doesn't work try specifying the $_table_name property for the same reason.
I'm trying to also grasp the concept here. In order to think like an ORM in this regard, you need to start with tables that the main tables reference as related information.
So in my world, I have a waste report, (model/waste/report) and there exists another table that has all the codes (model/waste/codes). so in the waste_reports table there's a column called code. That field might have 2E. 2E means nothing without the waste_codes table. The waste_codes table is (id, code, name).
I defined this relationship as such:
class Model_Waste_code extends ORM {
protected $_primary_key = "code";
protected $_has_one = array(
'waste_report' => array()
);
}
Then in my waste report model:
class Model_Waste_report extends ORM
{
protected $_belongs_to = array(
'codes' => array(
'model' => 'waste_code',
'foreign_key' => 'code'
)
);
}
To show different examples:
public function action_ormwaste() {
$test = ORM::factory('waste_report',76);
if ($test->loaded())
echo $test->codes->name;
echo "<hr noshade />";
$test = ORM::factory('waste_report')->find_all();
foreach($test as $row)
echo $row->codes->name . "<BR>";
}
Would output:
Error with image file (mirrored, etc)
-------------------------------------
Wrong Size
Extra Prints
Error with image file (mirrored, etc)
etc...
So in essense, the join on the data is handled on the fly. I'm using Kohana 3.2.
Thanks, that cleared me up.
