问题:Doctrine 注册自定义 DQL 函数

我想创建一个返回半径内所有广告的方法,所以我试图添加函数:earth_distance_operator、earth_box、ll_to_earthpostgress。

配置.yml

orm:
        auto_generate_proxy_classes: "%kernel.debug%"
        auto_mapping: true
        dql:
            numeric_functions:
                earth_box: Delivve\WebBundle\DQL\EarthBox
                ll_to_earth: Delivve\WebBundle\DQL\LLToEarth
                earth_distance_operator: Delivve\WebBundle\DQL\EarthDistanceOperator

EarthBox.php

class EarthBox extends FunctionNode
{
    private $earth;
    private $radius;

    public function getSql(SqlWalker $sqlWalker)
    {
        return 'earth_box(' . $this->earth->dispatch($sqlWalker) . ', ' . $this->radius->dispatch($sqlWalker) . ')';
    }

    public function parse(Parser $parser)
    {
        $parser->match(Lexer::T_IDENTIFIER);
        $parser->match(Lexer::T_OPEN_PARENTHESIS);

        $this->earth = $parser->StringPrimary();
        $parser->match(Lexer::T_COMMA);

        $this->radius = $parser->ArithmeticPrimary();
        $parser->match(Lexer::T_CLOSE_PARENTHESIS);
    }
} 

EarthDistanceOperator.php

class EarthDistanceOperator extends FunctionNode
{
    private $operator;
    private $first;
    private $second;

    /**
     * @param SqlWalker $sqlWalker
     *
     * @return string
     */
    public function getSql(SqlWalker $sqlWalker)
    {
        return sprintf("%s %s %s",
            $this->first->dispatch($sqlWalker),
            $this->operator->value,
            $this->second->dispatch($sqlWalker)
        );
    }
    /**
     * @param Parser $parser
     *
     * @return void
     */
    public function parse(Parser $parser)
    {
        $parser->match(Lexer::T_IDENTIFIER);
        $parser->match(Lexer::T_OPEN_PARENTHESIS);

        $this->first = $parser->StringPrimary();
        $parser->match(Lexer::T_COMMA);

        $this->operator = $parser->StringExpression();
        $parser->match(Lexer::T_COMMA);

        $this->second = $parser->StringPrimary();
        $parser->match(Lexer::T_CLOSE_PARENTHESIS);
    }
} 

LLToEath.php

class LLToEarth extends FunctionNode
{
    private $latitude;
    private $longitude;

    public function getSql(SqlWalker $sqlWalker)
    {
        return 'll_to_earth(' . $this->latitude->dispatch($sqlWalker) . ', ' . $this->longitude->dispatch($sqlWalker) . ')';
    }

    public function parse(Parser $parser)
    {
        $parser->match(Lexer::T_IDENTIFIER);
        $parser->match(Lexer::T_OPEN_PARENTHESIS);

        $this->latitude = $parser->ArithmeticPrimary();
        $parser->match(Lexer::T_COMMA);

        $this->longitude = $parser->ArithmeticPrimary();
        $parser->match(Lexer::T_CLOSE_PARENTHESIS);
    }
} 

我的问题是,当我在存储库中创建函数时,他没有给函数 ll_to_eath 无限期

AdRepository.php

    public function findByExceptOwner($paramFetcher)
    {
        $departureOriginal = $paramFetcher['departure'];
        $departureArray = preg_split('/ - /', $departureOriginal);
        $departureCityArray = preg_split('/,/', $departureArray[count($departureArray) - 2]);
        $departureUFArray = preg_split('/,/', $departureArray[count($departureArray) - 1]);
        $departure = $departureCityArray[count($departureCityArray) -1].' - '.$departureUFArray[0];

        $destinationOriginal = $paramFetcher['destination'];
        $destinationArray = preg_split('/ - /', $destinationOriginal);
        $destinationCityArray = preg_split('/,/', $destinationArray[count($destinationArray) - 2]);
        $destinationUFArray = preg_split('/,/', $destinationArray[count($destinationArray) - 1]);
        $destination = $destinationCityArray[count($destinationCityArray) -1].' - '.$destinationUFArray[0];

        dump($departure);
        dump($destination);

        $query = $this->getEntityManager()->createQueryBuilder('ad');

        // parâmetros iniciais da query: status, departure de destination
        $query->select('ad')
            ->from('DelivveWebBundle:'.$paramFetcher['type'], 'ad')
            ->where('ad.owner <> :ownerId')
            ->andWhere($query->expr()->eq('ad.status', ':status'))
            ->andWhere($query->expr()->like('ad.departure', ':departure'))
            ->andWhere($query->expr()->like('ad.destination', ':destination'))
            ->andWhere('ad.dateFinal <= :today')
            ->setParameter('ownerId', $paramFetcher['ownerId'])
            ->setParameter('status', 'new')
            ->setParameter('departure', "%{$departure}%")
            ->setParameter('destination', "%{$destination}%")
            ->setParameter('today', new \DateTime("now"));

        // raio de busca com centro nas coordenadas de departure
        if ($paramFetcher['departure_latitude'] && $paramFetcher['departure_longitude'] && $paramFetcher['radius']) {
            $query
                ->andWhere('earth_distance_operator(earth_box(ll_to_earth(:departure_lat, :departure_lon), :radius), \'@>\', ll_to_earth(ad.departureLatitude, ad.departureLongitude)) = true')
                ->setParameter('departure_lat', floatval($paramFetcher['departure_latitude']), \Doctrine\DBAL\Types\Type::FLOAT)
                ->setParameter('departure_lon', floatval($paramFetcher['departure_longitude']), \Doctrine\DBAL\Types\Type::FLOAT)
                ->setParameter('radius', floatval($paramFetcher['radius']) / 1.609, \Doctrine\DBAL\Types\Type::FLOAT);
        }

        // raio de busca com centro nas coordenadas de destionation
        if ($paramFetcher['destination_latitude'] && $paramFetcher['destination_longitude'] && $paramFetcher['radius']) {
            $query
                ->andWhere('earth_distance_operator(earth_box(ll_to_earth(:destination_lat, :destination_lon), :radius), \'@>\', ll_to_earth(ad.destinationLatitude, ad.destinationLongitude)) = true')
                ->setParameter('destination_lat', floatval($paramFetcher['destination_latitude']), \Doctrine\DBAL\Types\Type::FLOAT)
                ->setParameter('destination_lon', floatval($paramFetcher['destination_longitude']), \Doctrine\DBAL\Types\Type::FLOAT)
                ->setParameter('radius', floatval($paramFetcher['radius']) / 1.609, \Doctrine\DBAL\Types\Type::FLOAT);
        }

        dump($query->getQuery());
        dump($query->getQuery()->getResult());
        die();
        return ;
    }

这是这个给的错误,有人帮助我吗?

解答

事实上,错误不在代码中,而是在我机器的配置中。我的银行没有安装earthdistance模块;

安装模块:

CREATE EXTENSION cube;
CREATE EXTENSION earthdistance;
