I have 2 tables "user", "contact",
the relation between two tables is one user has many contact
Table member
m_id
name
------------
Table Contact
c_id
c_m_id
value
in zend model class, i do it in this way
/* Member.php */
class Default_Model_DbTable_Member extends Zend_Db_Table_Abstract
{
protected $_name = 'member';
protected $_dependentTables = array('Default_Model_DbTable_Contact');
}
/* Contact.php */
class Default_Model_DbTable_Contact extends Zend_Db_Table_Abstract
{
protected $_name = 'contact';
protected $_referenceMap = array(
'Member' => array(
'columns'=> array('c_id'),
'refTableClass'=> 'Default_Model_DbTable_Member',
'refColumns'=> array('c_m_id')
)
);
/* IndexController.php */
class IndexController extends Zend_Controller_Action
{
public function indexAction()
{
$m= new Default_Model_DbTable_Member();
$row = $m->find(1);
$data = $row->current();
$data = $data->findDependentRowset('Default_Model_DbTable_Contact');
print_r($data->toArray());
}
}
But i just get Invalid parameter number: no parameters were bound , my goal is to search a member detail record, and it also contains a array which store all contact info (i can use join method to do that, but i just want to try zend feature)
Have you tried defining
class Default_Model_DbTable_Member extends Zend_Db_Table_Abstract
{
protected $_name = 'member';
protected $_primary = 'm_id'; <---
I've always put the $_dependentTables and $_referenceMap in both connected tables (Contact & Member). Did you try that?

i have a problem that make my head blow about eloquent went to the wrong table here my code for my activity model
class Activity extends Model{
use HasFactory;
protected $table = 'activities';
protected $guarded = ['id'];
public function getRouteKeyName()
{
return 'slug';
}
and the problem is when i store to the database, eloquent went to the wrong table
here is my store method
public function store(StoreActivityRequest $request)
{
$validatedData = $request->validate([
'name' => 'required',
'slug' => 'required|unique:activies'
]);
Activity::create($validatedData);
return redirect('/activities')->with('success', 'Tindakan Berhasil Ditambahkan');
}
this is my customrequest (actually my laravel make it by default)
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class StoreActivityRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
//
];
}
}
here is the message
Illuminate\Database\QueryException
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'klinik_app.activies' doesn't exist (SQL: select count(*) as aggregate from `activies` where `slug` = konsultasi)
its go to activies table... if i change the tables on migrate file to activies, then the other method gone wrong because it's can't found activities. and this problem just happen to my store method, another method just do the right thing... is there any body can help me?
Update: Added from comments:
public function store(StoreActivityRequest $request) {
$validatedData = $request->validate([
'name' => 'required',
'slug' => 'required|unique:activies'
]);
Activity::create($validatedData);
return redirect('/activities')->with('success', 'Tindakan Berhasil Ditambahkan');
}
The application have the models:
NotificationParent.php
class NotificationParent extends Model{
use SoftDeletes;
protected $table = 'NotificationParent';
protected $primaryKey = 'notificationparent_id';
protected $fillable = ['category', 'description'];
protected $dates = ['deleted_at'];
public function notifications()
{
return $this->hasMany('App\Models\Notification', 'notificationparent_id', 'notification_id');
}
}
Notification.php
class Notification extends Model{
use SoftDeletes;
protected $table = 'Notification';
protected $primaryKey = 'notification_id';
protected $fillable = ['notificationparent_id', 'title', 'description', 'link'];
protected $dates = ['deleted_at'];
public function notificationParent()
{
return $this->hasOne('App\Models\NotificationParent', 'notification_id', 'notificationparent_id');
}
}
I could not save a notification with following code:
$notification = new Notification(['title' => 'access denied', 'description' => 'access denied for user one' , 'link' => 'http----']);
$notificationParent = NotificationParent::where('category', '=', 'admin')->first();
$notificationParent->notifications()->save($notification);
even though $notificationParent is not null it gives error:
SQLSTATE[23000]: [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Cannot insert the value NULL into column 'notificationparent_id', table 'five.dbo.Notification'; column does not allow nulls. INSERT fails. (SQL: insert into [Notification] ([title], [description], [link], [notificationparent_id], [updated_at], [created_at]) values (access denied, access denied for user one, http---, , 2015-04-21 16:02:57.000, 2015-04-21 16:02:57.000))
hasOne is used for a one to one relationship.
The inverse of hasMany is belongsTo
Im am new in Zend Framework.
I have this structure of codes .
DBTable
class Application_Model_DbTable_Employee extends Zend_Db_Table_Abstract
{
protected $_name = 'tab_employee';
}
Model
public function selectAllEmployees(){
$tblEmployee = new Application_Model_DbTable_Employee();
$tblEmployee->select('*');
}
But i can can't get all the data of all the employee .
public function selectAllEmployees(){
$tblEmployee = new Application_Model_DbTable_Employee();
return $tblEmployee->fetchAll($tblEmployee->select());
}
Try this code in model:
public function selectAllEmployees(){
$tblEmployee = new Application_Model_DbTable_Employee();
$rowset = $tblEmployee->fetchAll();
return $rowset;
}
For further information read this http://framework.zend.com/manual/1.12/en/zend.db.table.rowset.html#zend.db.table.rowset.to-array
Model function
public function selectAllEmployees()
{
$selectSql = $this->select();
$selectSql->from($this->_name, array('*'))
->order(id DESC');
return $this->fetchAll($selectSql);
}
in the controller
$employeeModel = new Application_Model_Employee();
$employees = $employeeModel->selectAllEmployees();
Maks3w is correct as well as terse.
Here is a little more detail.
There are a number of ways to use your Application_Model_DbTable_Employee to access and query your tab_employee table of your database.
The easiest way is to query directly from the dbTable model itself:
class Application_Model_DbTable_Employee extends Zend_Db_Table_Abstract
{
protected $_name = 'tab_employee';
public function selectAllEmployees()
{
//$this refers to the current dbTable object
$select = $this->select();
//when querying from the dbTable the from() parameter is assumed to be $this->_name, array('*')
//there several other sql commands available to the select(), where(), orWhere(), join()
$select->order('id DESC');
$result = $this->fetchAll($select);
return $result;
}
}
Controller code:
public function indexAction(){
model = new Application_Model_DbTable_Employee();
$employees = $model->selectAllEmployees();
$this->view->employees = $employees
}
Often a mapper model is used to access the database and provide the data to an entity model. This is also very common a relatively simple to accomplish. The key item to remember when designing the mapper is to include code to access the dbTable model as the database adapter, often called the gateway, here is some example code:
<?php
//This is one way to build a mapper
abstract class My_Model_Mapper_Abstract
{
/**
* Instance of Zend_Db_Table_Abstract
*/
protected $tableGateway = null;
/**
* Will accept a DbTable model passed or will instantiate
* a Zend_Db_Table_Abstract object from table name.
*/
public function __construct(Zend_Db_Table_Abstract $tableGateway = null)
{
if (is_null($tableGateway)) {
$this->tableGateway = new Zend_Db_Table($this->_tableName);
} else {
$this->tableGateway = $tableGateway;
}
}
/**
* Get default database table adapter
*/
protected function getGateway()
{
return $this->tableGateway;
}
/**
* findAll() is a proxy for the fetchAll() method and returns
* an array of entity objects.
*
* #param $where, primary key id
* #param string $order in the format of 'column ASC'
* #return array of entity objects
*/
public function findAll($where = null, $order = null)
{
$select = $this->getGateway()->select();
if (!is_null($where)) {
$select->where('id = ?', $where);
}
if (!is_null($order)) {
$select->order($order);
}
$rowset = $this->getGateway()->fetchAll($select);
$entities = array();
foreach ($rowset as $row) {
$entity = $this->createEntity($row);
$this->setMap($row->id, $entity);
$entities[] = $entity;
}
return $entities;
}
/**
* Abstract method to be implemented by concrete mappers.
*/
abstract protected function createEntity($row);
}
The concrete model might look like:
<?php
class Application_Model_Mapper_Employee extends My_Model_Mapper_Abstract
{
protected $tableName = 'tab_employee';
//I hard code the $tableGateway though this is probably not the best way.
//$tableGateway should probably be injected, but I'm lazy.
public function __construct(Zend_Db_Table_Abstract $tableGateway = null)
{
if (is_null($tableGateway)) {
$tableGateway = new Application_Model_DbTable_User();
} else {
$tableGateway = $tableGateway;
}
parent::__construct($tableGateway);
}
//create the Entity model
protected function createEntity($row)
{
$data = array(
'id' => $row->id,
'name' => $row->name,
'password' => $row->password,
);
$employee = new Application_Model_Employee($data);
return $employee;
}
}
to use this in a controller might look like:
public function indexAction(){
model = new Application_Model_Mapper_Employee();
$employees = $model->findAll();
}
and the most direct way to query your database is least recommended way, directly from the controller:
public function indexAction(){
model = new Application_Model_DbTable_Employee();
$employees = $model->fetchAll();
$this->view->employees = $employees
}
I hope this provides you some help and not to much confusion.
I have class that representing model of user with foreign key with is id of picture .
class Model_User extends Model_AbstractEntity
{
protected $u_id;
protected $u_email;
protected $u_firstname;
protected $u_lastname;
protected $u_password;
protected $u_salt;
protected $u_created_at;
protected $u_updated_at;
protected $u_fb;
protected $u_status;
protected $u_r_id;
protected $u_p_id;
}
Class with is responsible for picture model look like this:
class Model_Picture extends Model_AbstractEntity
{
protected $p_id;
protected $p_created_at;
protected $p_updated_at;
protected $p_caption;
protected $p_name;
protected $p_basePath;
protected $p_available;
protected $p_u_id;
}
This is only model part with is getting data from database.
Foreing key is u_p_id and key in picture is p_id
My problem is that when doing select() by Zend db table it returning me data with foreign key but how can I know which part of return data is picture part to set the proper picture model.... how to do it in proper way no to do 2 queries one for user and second for picture to create 2 associative objects.
I'm talking now about relation ont to one but maybe will be one to many..
Typically your entity models will not exist in void they will exist in concert with some type of Data Mapper Model. The Mapper will typically be charged with gathering the data from whatever source is handy and then constructing the entity model.
For example I have a music collection that has an album entity:
<?php
class Music_Model_Album extends Model_Entity_Abstract implements Interface_Album
{
//id is supplied by Entity_Abstract
protected $name;
protected $art;
protected $year;
protected $artist; //alias of artist_id in Database Table, foreign key
protected $artistMapper = null;
/**
* Constructor, copied from Entity_Abstract
*/
//constructor is called in mapper to instantiate this model
public function __construct(array $options = null)
{
if (is_array($options)) {
$this->setOptions($options);
}
}
/**
* Truncated for brevity.
* Doc blocks and normal getters and setters removed
*/
public function getArtist() {
//if $this->artist is set return
if (!is_null($this->artist) && $this->artist instanceof Music_Model_Artist) {
return $this->artist;
} else {
//set artist mapper if needed
if (!$this->artistMapper) {
$this->artistMapper = new Music_Model_Mapper_Artist();
}
//query the mapper for the artist table and get the artist entity model
return $this->artistMapper->findById($this->getReferenceId('artist'));
}
}
//set the artist id in the identity map
public function setArtist($artist) {
//artist id is sent to identity map. Can be called later if needed - lazy load
$this->setReferenceId('artist', $artist);
return $this;
}
//each album will have multiple tracks, this method allows retrieval as required.
public function getTracks() {
//query mapper for music track table to get tracks from this album
$mapper = new Music_Model_Mapper_Track();
$tracks = $mapper->findByColumn('album_id', $this->id, 'track ASC');
return $tracks;
}
}
In the mapper I would build the entity model like:
//excerpt from Model_Mapper_Album
//createEntity() is declared abstract in Model_Mapper_Abstract
public function createEntity($row)
{
$data = array(
'id' => $row->id,
'name' => $row->name,
'art' => $row->art,
'year' => $row->year,
'artist' => $row->artist_id,//
);
return new Music_Model_Album($data);
}
to use this method in a mapper method, might look like:
//this is actually from Model_Mapper_Abstract, b ut give the correct idea and will work in any of my mappers.
//this returns one and only one entity
public function findById($id)
{
//if entity id exists in the identity map
if ($this->getMap($id)) {
return $this->getMap($id);
}
//create select object
$select = $this->getGateway()->select();
$select->where('id = ?', $id);
//fetch the data
$row = $this->getGateway()->fetchRow($select);
//create the entity object
$entity = $this->createEntity($row);
//put it in the map, just in case we need it again
$this->setMap($row->id, $entity);
// return the entity
return $entity;
}
I have seen Entities and Mappers built in many different ways, find the method that you like and have fun.
A lot of code has been left out of this demonstration as it doesn't really apply to the question. If you need to see the complete code see it at GitHub.
I have a code something like following
class Application_Model_Company extends Zend_Db_Table_Abstract {
protected $_name = 'companies';
private $id;
private $name;
private $shortName;
private $description;
public static function getAllCompanies() {
$companyObj = new self();
$select = $companyObj->select()->order(array('name'));
$rows = $companyObj->fetchAll($select);
if($rows) {
$companies = array();
foreach($rows as $row) {
$company = new self();
$company->id = $row->id;
$company->name = $row->name;
$company->shortName = $row->short_name;
$company->description = $row->description;
$companies[] = $comapny;
}
// return Company Objects
return $companies;
}else
throw new Exception('Oops..');
}
}
I need to return Company Objects from getAllCompanies() function, But it returns Zend_Db_Table_Row Object. How do I correct this?
Your Model class shouldnt extend the table class. The table class is separate. Your Model should extend the row class if extending anything from Zend_Db at all. Also you shouldnt put retrieval methods on your Model classes directly, they would go on the table classes.
This is because in the paradigm youre trying to use here, a Model represents a single Row of data, the Table class represents the table as a repository of data, and the Rowset class represents a collection of Rows (or Models).
To properly implement what you are describing in your question you would do something like the following:
class Application_Model_DbTable_Company extends Zend_Db_Table_Abstract
{
// table name
protected $_name = 'company';
protected _$rowClass = 'Application_Model_Company';
// your custom retrieval methods
}
class Application_Model_Company extends Zend_Db_Table_Row
{
protected $_tableClass = 'Application_Model_DbTable_Company';
// custom accessors and mutators
}
However, using some kind of implementation of the Data Mapper pattern is whats actually recommended. Check out the Quickstart for a thorough tutorial on a simplified implementation.
