First of all, I want to apologize for the length of this question; I didn't know how to properly ask my question without a lot of background. Please bear with me.
I'm converting a simple application that I use to hone my skills from my own custom database access schema to Doctrine. I chose Doctrine for a number of reasons, not the least of which is that I use it at my day job regularly. I also like how Doctrine is generally a pretty thin (appearing) layer that stays out of the way while still adding a lot of features.
I've converted the data access layer for the users table in my database to Doctrine.
It's very unremarkable (simply getters and setters), except for a few fine details:
- I need to have a custom repository for some specific queries and
- the
Userobject has a defaultArrayCollectioninstantiated in the constructor
namespace model\entities;
/**
* @Entity(repositoryClass="modelepositories\UserRepository")
* @Table(name="users")
*/
class User{
/* snip variables */
/**
* @OneToOne(targetEntity="Authentication", mappedBy="user", cascade="persist")
*/
private $authentication;
/**
* @OneToMany(targetEntity="Contact", mappedBy="user", cascade="persist")
*/
private $contacts;
public function __construct() {
$this->contacts = new \Doctrine\Common\Collections\ArrayCollection();
}
/* snip getters and setters */
}
In my old schema, I had two custom queries that selected a subset of the users table.
They are:
public function search( $term = null ){
if( !$term ){
$sql = "SELECT *
FROM
" . $this->tableName . "
ORDER BY
lname ASC,
fname ASC";
$res = $this->db->q($sql);
}
else{
$sql = "SELECT *
FROM
" . $this->tableName . "
WHERE
lname LIKE ?
OR fname LIKE ?
OR CONCAT(fname, ' ', lname) LIKE ?
ORDER BY
lname ASC,
fname ASC";
$values = array( '%' . $term . '%', '%' . $term . '%', '%' . $term . '%' );
$res = $this->db->qwv( $sql, $values );
}
return $this->wrap( $res );
}
and:
public function getAllWithRestrictions(){
$sql = "SELECT *
FROM
" . $this->tableName . "
WHERE
userid IN
(
SELECT
userid
FROM
" . $this->uiPre . "authentications
WHERE
resetPassword = 1
OR disabled = 1
)";
$res = $this->db->q( $sql );
return $this->wrap($res);
}
where $this->db is a thin PHP PDO wrapper and $this->wrap does magic with zero/single/multiple rows returned and converting them into data objects.
Now, I figured this would be very easy to convert to Doctrine. In the case of getAllWithRestrictions it's simply a ->where, ->orWhere set, right? I don't know anymore.
I found these Stackoverflow questions that I used to try to construct my queries, but I'm running into error after error, and I'm not sure how far down the rabbit hole I need to go:
SQL Multiple sorting and grouping
Order by multiple columns with Doctrine
Doctrine: Multiple (whereIn OR whereIn) query?
Doctrine - or where?
My custom repository currently looks like this, but I can't say it's even close to correct as I've been fiddling with it for a long time, and it's just a hodge-podge of what I thought might work:
<?php
namespace modelepositories;
use Doctrine\ORM\EntityRepository;
use Doctrine\ORM\Query\Expr;
class UserRepository extends EntityRepository{
public function search( $term ){
if( !$term ){
return $this
->_em
->createQuery('SELECT u FROM model\entities\User u')
->addOrderBy( 'u.lname' )
->addOrderBy( 'u.fname' )
->getResult();
}
else{
$qb = $this->_em->createQueryBuilder();
$qb ->select(array('u'))
->from('model\entities\User', 'u')
->where( $qb->expr()->like( 'u.lname', '?1' ) )
->orWhere( $qb->expr()->like( 'u.fname', '?2' ) )
->orWhere( $qb->expr()->like( 'CONCAT(u.fname, \' \', u.lname)', '?3' ) )
->addOrderBy( 'u.lname' )
->addOrderBy( 'u.fname' )
->setParameters(
array(
1 => $term,
2 => $term,
3 => $term
)
);
$query = $qb->getQuery();
return $query->getResult();
}
}
public function getAllWithRestrictions(){
$qb = $this->_em->createQueryBuilder();
$qb ->select(array('u'))
->from('model\entities\User', 'u')
->add('where', $qb->expr()->orx(
$qb->expr()->eq('u.disabled', '1'),
$qb->expr()->eq('u.resetPassword', '1')
));
$query = $qb->getQuery();
return $query->getResult();
}
}
EDIT: I just realized that I'm doing the getAllWithRestrictions query on the wrong table (it should be authentications.) In any case, it's the search method causing my issues right now. However, I will also need to know how to do something like $qb->expr()->eq('u.Authentication.disabled = '1') and I have no idea how DQL really works.
The particular error I'm getting right now is
-
Fatal error: Uncaught exception 'Doctrine\ORM\Query\QueryException' with message 'SELECT u FROM model\entities\User u WHERE u.lname LIKE ?1 OR u.fname LIKE ?2 OR CONCAT(u.fname, ' ', u.lname) LIKE ?3 ORDER BY u.lname ASC, u.fname ASC'
followed by
Doctrine\ORM\Query\QueryException: [Syntax Error] line 0, col 99: Error: Expected Doctrine\ORM\Query\Lexer::T_CLOSE_PARENTHESIS, got ','
But I've had a slew of different issues depending on how I construct the DQL/Query Builder.
Again, I expected these two SQL queries to be simple to convert to Doctrine / DQL. I'd like to do this without resorting to raw SQL through Doctrine (as many of the accepted answers I linked suggest). This MUST be easy. Does anyone know how to construct elegant Doctrine queries?
