I don't know the syntax to access "CurrentTable.ForeignKey" nor "OtherTable.PrimaryKey" in a $model->addCondition() statement.
This is a fragment of my code which works:
$mm = new SYSPC_MODEL($this->app->db,['title_field'=>'MODEL_NAME']);
$mm->addCondition('MODEL_NAME', 'LIKE', 'DESK%');
In place of simply searching for MODEL_NAME like 'DESK%', I would like to display only the FK_MODEL_id values which exist in the SYSPC_MODEL table for the same FK_OS_ID than the current record FK_OS_ID value. So in SQL, we should have something like:
SELECT SYSPC_MODEL.MODEL_NAME WHERE ( DHCP_PC.FK_OS_ID = SYSPC_MODEL.id )
To understand easier the context, I reduced my code as much as possible:
<?php
include_once ('../include/config.php');
require '../vendor/autoload.php';
class SYSPC_OS extends \atk4\data\Model {
public $table = 'SYSPC_OS';
function init() {
parent::init();
$this->addFields([ ['OS_NAME', 'required'=>true, 'caption'=>'Identifiant d\'OS'],
['OS_DESCRIPTION', 'required'=>true, 'caption'=>'Description d\'OS']
]);
}
} // End of class SYSPC_OS
class SYSPC_MODEL extends \atk4\data\Model {
public $table = 'SYSPC_MODEL';
function init() {
parent::init();
$this->addFields([ ['MODEL_NAME', 'caption'=>'Nom du modele'],
['MODEL_BASE_RPM', 'caption'=>'Rpm de base']
]);
$this->hasOne('FK_OS_id',[new SYSPC_OS(),'ui'=>['visible'=>false]])->addField('OS_NAME','OS_NAME');
}
} // End of class SYSPC_MODEL
class DHCP_PC extends \atk4\data\Model {
public $table = 'DHCP_PC';
function init() {
parent::init();
$this->addFields([ ['PCNAME', 'required'=>true, 'caption'=>'Nom du pc']
]);
$this->hasOne('FK_OS_ID',['required'=>true,new SYSPC_OS(),'ui'=>['visible'=>false]])->addField('OS_NAME','OS_NAME');
$this->setOrder('PCNAME','asc');
$this->hasOne('FK_MODEL_id',['required'=>true,new SYSPC_MODEL(),'ui'=>['visible'=>false]])->addField('MODEL_NAME','MODEL_NAME');
}
} // End of class DHCP_PC
class PcForm extends \atk4\ui\Form {
function setModel($m, $fields = null) {
$PcWidth = 'three';
parent::setModel($m, false);
$gr = $this->addGroup('PC name');
$gr->addField('PCNAME',['required'=>true,'caption'=>'Nom du pc']);
$gr = $this->addGroup('OS');
$mm2 = new SYSPC_OS($this->app->db,['title_field'=>'OS_NAME']);
$gr->addField('FK_OS_ID',['width'=>$PcWidth],['DropDown'])->setModel($mm2);
$gr = $this->addGroup('Modèle');
$mm = new SYSPC_MODEL($this->app->db,['title_field'=>'MODEL_NAME']);
$mm->addCondition('MODEL_NAME', 'LIKE', 'DESK%'); // Works fine but I would like to display only the FK_MODEL_id values
// which exist in the SYSPC_MODEL table for the same FK_OS_ID
// than the current record FK_OS_ID value :
// SELECT SYSPC_MODEL.MODEL_NAME WHERE ( DHCP_PC.FK_OS_ID = SYSPC_MODEL.id )
$gr->addField('FK_MODEL_id', ['width'=>$PcWidth], ['DropDown'])->setModel($mm);
return $this->model;
}
} // End of class PcForm
$app = new \atk4\ui\App();
$app->title = 'Gestion des PC';
$app->initLayout($app->stickyGET('layout') ?: 'Admin');
$app->db = new \atk4\data\Persistence_SQL(
"pgsql:host=".$GLOBALS['dbhost'].";dbname=".$GLOBALS['dbname'],
$GLOBALS['dbuser'],
$GLOBALS['dbpass']
);
$g = $app->add(['CRUD', 'formDefault'=>new PcForm()]);
$g->setIpp([10, 25, 50, 100]);
$g->setModel(new DHCP_PC($app->db),['PCNAME', 'OS_NAME', 'MODEL_NAME']);

Please look at https://github.com/atk4/ui/pull/551 - it might be what you're looking for.
Example here: https://ui.agiletoolkit.org/demos/autocomplete.php
Docs: https://agile-ui.readthedocs.io/en/latest/autocomplete.html?highlight=lookup#lookup-field
$form = $app->add(new \atk4\ui\Form(['segment']));
$form->add(['Label', 'Add city', 'top attached'], 'AboveFields');
$l = $form->addField('city',['Lookup']);
// will restraint possible city value in droddown base on country and/or language.
$l->addFilter('country', 'Country');
$l->addFilter('language', 'Lang');
//make sure country and language belong to your model.
$l->setModel(new City($db));
Alternatively you can use something other than drop-down, here is UI example:
https://ui.agiletoolkit.org/demos/multitable.php
Selecting value in the first column narrows down options in the next. You can have a hidden field inside your form where you can put the final value.
Thanks for your support but I still have some questions.
Question 1: I found "addRelatedEntity" and "relEntity" but I didn't found a description of those commands. Does it exist ? Is this a possible solution for my issue ?
Question 2: Is it possible to 'Lookup' in another table and if yes, how ?
Question 3: If 'Lookup' is not the solution, how to make a join (with filtering in the where clause) inside a model ?
Question 4: If the join is not the solution, is it possible to use DSQL inside a model ?
Question 5: Or do you have a DSQL example (with a self made join between several tables) associated with a CRUD ?

I have threads and messages on thread
I want to return all threads with the last message time, so I added a new field like this on thread model
public function fields()
{
$fields= ['idThread', 'idUser', 'title', 'unread', 'username','lastMesageTime'];
return $fields;
}
now with this method I get the calculated value lastMessageTime
public function getLastMessageTime()
{
return $this->hasMany(Messages::className(), ['idThread' => 'idThread'])
->select('time')->orderBy('time DESC')->limit(1)->scalar();
}
on my index method using active record like this
return Thread::find()->select('idThread, title, idUser')->all();
this works and I get lastMessageTime with the right value, but I want to order by so I can get the thread with the most recent lastMessageTime the first one, I tried with the following code
public function scopes() {
return array(
'byOrden' => array('order' => 'lastTimeMessage DESC'),
);
}
any idea?
Edit:
this workaround works, but I think this is not a good way because I'm not using active record so fields like username that I had defined on Thread model I had to fetch it again
$query = (new \yii\db\Query());
$query->select('*, (SELECT max(time) as lastMessageTime from messages where messages.idThread = thread.idThread ) lastMessageTime,
(SELECT name from users where users.idUser = thread.idUser) as name ')
->from('threads')
->where(['idUser'=>$idUser])
->orderBy('lastMessageTime DESC');
$rows = $query->all();
return $rows;
You can define extra fields as model properties, then override find method to load data for them.
class Thread extends \yii\db\ActiveRecord
{
public $lastMessageTime;
public static function find()
{
$q = parent::find()
->select('*')
->addSelect(
new \yii\db\Expression(
'(SELECT max(time) FROM messages WHERE messages.idThread = thread.idThread) AS lastMessageTime'
);
return $q;
}
}
Then you can load and order models like this:
$rows = Thread::find()->orderBy(['lastMessageTime' => SORT_DESC])->all();
I want to insert multiple record in my table using yii2 ActiveRecord.
I already know that I can use this code
$connection->createCommand()->batchInsert('user', ['name', 'age'], [
['Tom', 30],
['Jane', 20],
['Linda', 25],
])->execute();
but by this approach my model validations are not executing.
and I already have read this question
ActiveRecord batch insert (yii2)
but also by doing validation in a tricky way, consider I want to fill created_at and updated_at columns using ActiveRecords events.
just like this
public function beforeSave($insert)
{
if (parent::beforeSave($insert)) {
if($insert)
$this->created_at = date('Y-m-d H:i:s');
$this->updated_at = date('Y-m-d H:i:s');
return true;
} else {
return false;
}
}
I think is not good idea to use beforeSave events (and similar stuff) because it will trigger for each model. However you want save multiple models at once. I recommend to use bulk methods.
In similar cases I use usually following "bulk" approach (code not tested, just for example):
namespace common\components;
class Model extends yii\base\Model {
/**
* Saves multiple models.
*
* #param ActiveRecord[] $models
* #return bool
*/
public static saveMultiple($models){
if(count($models) > 0){
$firstModel = reset($models);
$columnsToInsert = $firstModel->attributes(); // here you can remove excess columns. for example PK column.
$modelsToInsert = [];
$rowsToInsert = [];
foreach($models as $model){
if ($this->beforeSave(true)) {
$modelsToInsert[] = $model;
}
}
foreach($modelsToInsert as $model){
$rowsToInsert[] = array_values($model->attributes); // here you can remove excess values
}
$numberAffectedRows = \Yii::$app->db->createCommand()
->batchInsert($firstModel->tableName(), $columnsToInsert, $rowsToInsert)
->execute();
$isSuccess = ($numberAffectedRows === count($models));
if($isSuccess){
$changedAttributes = array_fill_keys($columnsToInsert, null);
foreach($modelsToInsert as $model){
$model->afterSave(true, $changedAttributes);
}
}
return $isSuccess;
} else {
return true;
}
}
}
This class can be used:
use common\components\Model;
/**
* #var SomeActiveRecord[] $models Array that contains array of active records (type SomeActiveRecord)
*/
// ...
if (Model::validateMultiple($models)){
if(!Model::saveMultiple($models)){
// ... some error handling
}
} else {
foreach($models as $model){
if($model->hasErrors()){
$errors = $model->getFirtsErrors();
// ... some error handling
}
}
}
Additionally, for more convenient working with multiple models can be developed special Collection class that implements \ArrayAccess and \Iterator interfaces. This collection can iterated as simple array, however it contains special methods for bulk operations. Something like this:
foreach($modelCollection as $model){
// ...
}
$modelCollection->validate(); // works similar to common\components\Model::validateMultiple()
$modelCollection->save(); // works similar to common\components\Model::saveMultiple()
I'm working on a project using CakePHP 3.x.
I have UserAddress, ServiceRequests, Service models.
There is a button on service/view/$id which when clicked will ask user to select address from service-requests/serviceArea which has a list of addresses added by user. service-requests/serviceArea view will contain a select button which when clicked will call add action in ServiceRequests controller with passing two parameters serviceId and userAddressId
This is the serviceArea function created by me.
public function serviceArea($id = null)
{
public $uses = array('UserAddress');
$service = $id;
$query = $userAddresses->find('all')
->where(['UserAddresses.user_id =' => $this->Auth->user('id')]);
$this->set(compact('userAddresses'));
$this->set('_serialize', ['userAddresses']);
}
How to display the address and also pass the $service parameter to the serviceArea view.
I am new to CakePHP, so if you think question is incomplete any edit to it will be appreciated instead of down-voting.
Thank You.
Edit 2
Thank for your answer #jazzcat
After changing my code according to yours and visiting http://domain.com/service-requests/service-area/$id. It is showing error as
Record not found in table "service_requests"
and pointing to the ServiceRequestsController on line no 33
The ServiceRequestController as containing line no 33 is
<?php
namespace App\Controller;
use App\Controller\AppController;
/**
* ServiceRequests Controller
*
* #property \App\Model\Table\ServiceRequestsTable $ServiceRequests
*/
class ServiceRequestsController extends AppController
{
/**
* isAuthorized method
*
*/
public function isAuthorized($user)
{
$action = $this->request->params['action'];
// The add and index actions are always allowed.
if(in_array($action, ['index', 'add', 'serviceRequests'])) {
return true;
}
// All other actions require an id.
if (empty($this->request->params['pass'][0])) {
return false;
}
// Check that the service request belongs to the current user.
$id = $this->request->params['pass'][0];
$serviceRequest = $this->ServiceRequests->get($id); // line : 33
if($serviceRequest->user_id == $user['id']) {
return true;
}
return parent::isAuthorized($user);
}
/* Other actions */
}
?>
This worked for me.
Just added the serviceArea action name in the isAuthorized method
if(in_array($action, ['index', 'add', 'serviceArea'])) {
return true;
}
and it's working fine as expected.
There is alot wrong with your code. Please read the docs
Is the table named user_addresses or user_address ?
You seem to mix the both.
The following would be the correct way to do it assuming your table is named user_addresses
public function serviceArea($id = null)
{
$this->loadModel('UserAddresses');
$userAddresses = $this->UserAddresses->find('all')
->where(['UserAddresses.user_id =' => $this->Auth->user('id')]);
// If you want to filter on the serviceArea ID aswell
if($id)
$userAddresses->andWhere(['id' => $id]);
// Setting SerivceArea ID to compact makes it available in view.
$serviceAreaId = $id;
$this->set(compact('userAddresses', 'serviceAreaId'));
$this->set('_serialize', ['userAddresses']);
}
This snippet:
$id = $this->request->params['pass'][0];
$serviceRequest = $this->ServiceRequests->get($id); // line : 33
Just checks if the first parameter passed to the method exists in ServiceRequests.
(That parameter could be anything, you have to keep that in mind when creating all your methods in that controller, that is to say the least.. bad)
I'm assuming that the service_requests table is associated with the users table and an user_id column exists in the service_requests table.
If that is the case this should work:
public function isAuthorized($user)
{
$action = $this->request->params['action'];
// The add and index actions are always allowed.
if(in_array($action, ['index', 'add'])) {
return true;
}
// Is not authorized if an argument is not passed to the method.
// Don't know why you'd want this , but sure.
if (empty($this->request->params['pass'][0])) {
return false;
}
// Check that the service request belongs to the current user.
$user_id = $this->Auth->user('id');
$serviceRequest = $this->ServiceRequests->find()->where(['ServiceRequests.user_id' => $user_id])->first();
if(!empty($serviceRequest)) {
return true;
}
return parent::isAuthorized($user);
}
A. I have a table with users and a table with friends and here are their connections:
This in the User class:
/**
* #ORM\OneToMany(targetEntity="Friend", mappedBy="user")
*/
protected $friends;
public function __construct()
{
$this->friends = new ArrayCollection();
}
and this is in the Friend class:
/**
* #ORM\ManyToOne(targetEntity="User", inversedBy="friends")
* #ORM\JoinColumn(name="user_id", referencedColumnName="id")
*/
protected $user;
I have an template, in which I render the friends of the current user just using
$friends = $user->getFriends();
But now I want to be able to sort the friends of the user. I created a repository class with this function:
public function findAllOrderedByName()
{
return $this->getEntityManager()
->createQuery('SELECT f FROM EMMyFriendsBundle:Friend f ORDER BY f.name ASC')
->getResult();
}
but it displays all the friends of all the users, not just the current user. Is there a way to show only the friends of the current user without using something like "WHERE friend.user_id = user.id"? If yes, please tell me how to do it.
B. Another thing I would like to ask is how to manage my controllers.
This is the action which renders the template to show all unsorted friends:
/*
* #Displays the basic information about all the friends of an user
*/
public function displayAction()
{
$user = $this->get('security.context')->getToken()->getUser();
if($user->getName() === NULL)
{
$name = $user->getUsername();
}
else
{
$name = $user->getName();
}
$this->get('session')->setFlash('hello', 'Hello, '.$name.'!');
$friends = $user->getFriends();
$cat = new Category();
$dd_form = $this->createForm(new \EM\MyFriendsBundle\Entity\ChooseCatType(), $cat);
return $this->render('EMMyFriendsBundle:Home:home.html.twig', array(
'name' => $name, 'friends' => $friends, 'user' => $user,
'dd_form' => $dd_form->createView()));
}
And I have a sortAction, but I don't know how to write it. It should be the same as the above, only the row
$friends = $user->getFriends();
should be replaced with
$friends = $em->getRepository('EMMyFriendsBundle:Friend')
->findAllOrderedByName();
but if I copy it, it's a lot code duplication and it's stupid. I thought of one controller with an if-statement, but what to have in it? Please give me some ideas! Thanks in advance!
Do this:
/**
* #ORM\OneToMany(targetEntity="Friend", mappedBy="user")
* #ORM\OrderBy({"name" = "ASC"})
*/
protected $friends;
When using $this->Form->input('fieldname'), CakePHP creates a label element that, by convention, uses the fieldname. I know I can specify another string to use for the label as an argument to the input method, but is there any way I can specify the label name in the model, so I don't have to repeat the label name in multiple ctp files (e.g. so I only have to change it in one place)?
So I created this and made a quick test which worked, however, can't guarantee it's bug free:
<?php
App::uses('FormHelper', 'View/Helper');
class MyFormHelper extends FormHelper {
public function label($fieldName = null, $text = null, $options = array()) {
if ($text === null) {
$entity = $this->entity();
$field = array_pop($entity);
$model = $this->model();
$object = $this->_models[$model];
if (isset($object->labels[$field])) {
$text = $object->labels[$field];
}
}
return parent::label($fieldName, $text, $options);
}
}
Drop that in app/View/Helper/MyFormHelper.php
Add it to the helper array and alias it if you want to.
Add a public $labels array to the model with field => label-text structure.
Hope it works.
