I have a relation many-to-many.
In Entity "Progetti" i have:
/**
*
* #var \Doctrine\Common\Collections\ArrayCollection $attivita
*
* #ORM\ManyToMany(targetEntity="Attivita", inversedBy="progetti",cascade={"persist", "remove" })
* #ORM\JoinTable(name="progetti_attivita",
* joinColumns={#ORM\JoinColumn(name="progetti_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="attivita_id", referencedColumnName="id")}
* )
*/
protected $attivita;
In Entity "Attività " i have:
/**
*
* #var \Doctrine\Common\Collections\ArrayCollection $progetti
* #ORM\ManyToMany(targetEntity="Progetti", mappedBy="attivita")
*/
protected $progetti;
Ok.
The JoinTable "progetti_attivita" has "attivita_id" and "progetti_id".
Now i added a new field to the JoinTable "progetti_attivita" and i called it "position". it's an integer.
I have the ProgettiType Form:
$builder
->add('nomeProgetto')
->add('descProgetto')
->add('noteProgetto')
->add('attivita', CollectionType::class, array(
'entry_type' => AttivitaType::class,
'allow_add' => true,
));
Ok.
I have the form that display all "attività " for "progetti".
My question is:
How can i say to Form to display "attivita" ordered by "position" ?
If you always want your collection to be ordered then you can add the OrderBy property to your Doctrine mapping:
http://doctrine-orm.readthedocs.io/projects/doctrine-orm/en/latest/tutorials/ordered-associations.html
/**
* #ManyToMany(targetEntity="Attivita")
* #OrderBy({"position" = "ASC"})
**/
private $attivitas;
An alternative approach would be to add a getAttivitaOrdered method to your Progetti entity:
class Progetti
getAttivitaOrdered() // return ordered list
->add('attivitaOrdered', CollectionType::class ...
Not sure if you will need a setAttivitaOrdered method or not when you post.
And your question is actually a little bit confusing. Adding a property to your join table means that you need to use OneToMany and ManyToOne relations instead of ManyToMany. So a few more adjustments will be needed.

I need to combine information from several tables.
In case of using entity I should create all possible fields as properties + setters/getters for them.
But on saving object - I should split / unset all properties which is not in main table.
Possibly there is more "true" way to deal with it, without using doctrine etc.
If I were you, I would take a closer look to Hydrators:
ZF2 docs on hydrators
Create a new class that implements the HydratorInterface:
namespace Zend\Stdlib\Hydrator;
interface HydratorInterface
{
/**
* Extract values from an object
*
* #param object $object
* #return array
*/
public function extract($object);
/**
* Hydrate $object with the provided $data.
*
* #param array $data
* #param object $object
* #return void
*/
public function hydrate(array $data, $object);
}
You need to implement 2 functions:
extract($object);
Extract will create an array from an object.
hydrate(array $data, $object);
Hydrate will create an object from an array.
When you do a select you can have all fields in 1 array, so there you have no problem to put it in the object. When extracting, you want it split up. You could implement extract in such a way:
public function extract($object)
{
return array(
'tbl1' => array(
'fld1' => $object->getFld1(),
'fld2' => $object->getFld2(),
'fld3' => $object->getFld3(),
),
'tbl2' => array(
'fld4' => $object->getFld4(),
'fld5' => $object->getFld5(),
),
'tbl3' => array(
'fld6' => $object->getFld6(),
'fld7' => $object->getFld7(),
'fld8' => $object->getFld8(),
'fld9' => $object->getFld9(),
),
);
}
When you then extract the data, you can pass each group of data to the correct table for insert or update.
I have trouble creating a CdbCriteria with nested join. Here's the code in model (sorry it's in Indonesian. Hopefully anyone can understand the query):
public function report() {
$criteria=new CDbCriteria;
$criteria->alias = "p";
$criteria->select = "p.tanggal_transaksi,
MONTH( p.tanggal_transaksi ) AS bulan,
p.kode,
p.kode_supplier,
s.nama,
d.kode_bahan_baku,
b.nama_barang,
d.jumlah_kg,
d.jumlah_cones,
d.harga_satuan,
d.harga_satuan * d.jumlah_cones AS total,
FLOOR(d.harga_satuan * d.jumlah_cones * p.ppn / 100) AS ppn,
(d.harga_satuan * d.jumlah_cones) + FLOOR(d.harga_satuan * d.jumlah_cones * p.ppn / 100) AS total_akhir
";
$criteria->join = "JOIN m_supplier s ON s.kode = p.kode_supplier
RIGHT JOIN t_pembelian_detail d ON d.kode_pembelian = p.kode
JOIN m_bahan_baku b ON b.kode = d.kode_bahan_baku
";
$criteria->together = TRUE;
return new CActiveDataProvider(get_class($this), array(
'criteria'=>$criteria,
));
}
The name of the model is TPembelian and here is the relation:
public function relations()
{
return array(
'supplier' => array(self::BELONGS_TO, 'MSupplier', 'kode_supplier'),
'tPembelianDetails' => array(self::HAS_MANY, 'TPembelianDetail', 'kode_pembelian'),
);
}
In a controller, I wrote these lines of codes to just simply print out each attributes of CActiveDataProvider:
$model = new TPembelian('search');
$dataProvider = $model->report();
foreach ($dataProvider->getData() as $data) {
echo "<pre>".print_r($data->attributes, 1)."</pre>";
}
the problem is, it only prints out the attributes from TPembelian model (which use alias "p"). Why are other attributes (with other alias beside "p") not printed?
I have searched for a while and it appears that CActiveDataProvider not returning one long query, but instead it returns many query with HAS_MANY relation. Someone said to use "together" and set it to TRUE (I wrote it already in the code above) to make it returns one long query, but it's still not working. Can anybody please help me?
Note:
in the first code, m_supplier, t_pembelian_detail, and m_bahan_baku are tables, not models
I'm customizing Magento FAQ extension for sort faq items by category.below collection is
used to get all items active faq items.
$collection = Mage :: getModel('flagbit_faq/faq')->getCollection()
->addStoreFilter(Mage :: app()->getStore())
->addIsActiveFilter();
there is relation table "faq_category_item"
Table structure:-
category_id faq_id
1 1
2 2
1 3
So I decide to join two tables.I unsuccess in that.
What i tried is below.
$tbl_faq_item = Mage::getSingleton('core/resource')->getTableName('faq_category_item');
$collection = Mage :: getModel('flagbit_faq/faq')->getCollection()
->getSelect()
->join(array('t2' => $tbl_faq_item),'main_table.faq_id = t2.faq_id','t2.category_id')
->addStoreFilter(Mage :: app()->getStore())
->addIsActiveFilter();
Whats wrong in this and how can i filter the particular category items.Please share some good links to learn Magento model collections.
Thanks in advance
The returned type from getSelect() and join() is a select object, not the collection that addStoreFilter() and addIsActiveFilter() belong to. The select part needs to occur later in the chain:
$collection = Mage :: getModel('flagbit_faq/faq')->getCollection()
->addStoreFilter(Mage :: app()->getStore())
->addIsActiveFilter();
// Cannot append getSelect right here because $collection will not be a collection
$collection->getSelect()
->join(array('t2' => $tbl_faq_item),'main_table.faq_id = t2.faq_id','t2.category_id');
Try this function from
Mage_Eav_Model_Entity_Collection_Abstract
/**
* Join a table
*
* #param string|array $table
* #param string $bind
* #param string|array $fields
* #param null|array $cond
* #param string $joinType
* #return Mage_Eav_Model_Entity_Collection_Abstract
*/
public function joinTable($table, $bind, $fields = null, $cond = null, $joinType = 'inner')
{
So to join tables you can do like this:
$collection->joinTable('table-to-join','left.id=right.id',array('alias'=>'field'),'some condition or null', joinType(left right inner));
I try to execute this query in my CompanyRepository

$query = $qb->getQuery();
echo($query->getSQL());
When I try to do it I having error:

What is wrong?
For those who came here with the question about "Expected end of string, got 'ON'", but could not find the right answer, as I couldn't (well, there is an answer, but not exactly about QueryBuilder). In general, yes, you don't need to specify the joining columns. But what if you need to add extra filtering. For example, I was looking to add an extra condition (to allow nulls in join).
The problem here is that even though the constant Join::ON exists (and comments in Join expression mention it as well), there is no ON in DQL. Instead, one should use WITH (Join::WITH).
Here is my usage example:
$qb->leftJoin('p.metadata', 'm', Join::WITH, "IFNULL(m.name, '') = 'email'");
P.S. Predicting questions about IFNULL() - it is a Benjamin Eberlei's Doctrine extension.
There's a pretty clear explanation about how JOIN's work with DQL here:
With DQL when you write a join, it can be a filtering join (similar to the concept of join in SQL used for limiting or aggregating results) or a fetch join (used to fetch related records and include them in the result of the main query). When you include fields from the joined entity in the SELECT clause you get a fetch join
this should be enough to get what you want (info about all companies with legal info loaded):
$query = $em->createQuery('SELECT c, ld FROM \Model\Entity\Company c JOIN c.legaldetails ld');
$companies = $query->getResult(); // array of Company objects with the legaldetails association loaded
EDIT:
i used a regular join in my query, so companies with no legal info won't be returned in the query. if you want ALL companies even though they have no legal info loaded you should try with the left join as you were doing
We both thought in terms of SQL. But in DQL WITH is used instead of ON. example
Edit:
If you know SQL, why you don't use query such as:
$query = $this->getEntityManager()->createQuery('
SELECT t...
');
Put there the SQL that you think should be there, check it. If it works - the problem is in Doctrine code, if not - the error is in SQL/DQL

You should upgrade to Propel 1.6.3 in order to get the advanced columns feature (ENUM for instance): http://www.propelorm.org/cookbook/working-with-advanced-column-types.html#enum_columns.
