我试图用自定义映射类型实现PostGis中的栅格功能。将光栅添加到数据库，Doctrine自定义映射类型带来数据库错误
我正在创建一个类型为栅格的列表。 要插入光栅数据，我要用st_makeemptyraster插入一个新的空Raster，用st_addband添加一个新的波段，并用st_setvalues设置值。
所以，这可能在普通的SQL做那样：
CREATE TABLE IF NOT EXISTS rasters (id serial, rast raster);
INSERT INTO rasters(id,rast)
VALUES(
3,
st_setvalues(
st_addband(
ST_MakeEmptyRaster(2, 2, 0.0005, 0.0005, 1, 1, 0, 0, 4326),
1,
'32BF',
1,
0
),
1,
1,
1,
ARRAY[[9, 9], [9, 9]]::double precision[][]
)
);
现在我试图在学说添加自定义映射类型的光栅。
我增加了一个实体光栅：
<?php

public function getUpperLeftX()
{
return $this->upperLeftX;

public function removeBand(RasterBand $band)
{
$this->bands->removeElement($band);
return $this;
}
}
而且自定义映射类型：
<?php
namespace AppBundle\Type;
use Doctrine\DBAL\Platforms\AbstractPlatform;
use Doctrine\DBAL\Types\Type;
class RasterType extends Type
{
const RASTER = 'raster';
public function getName()
{
return self::RASTER;
}
public function getSQLDeclaration(array $fieldDeclaration, AbstractPlatform $platform)
{
return 'raster';
}
public function convertToPHPValue($value, AbstractPlatform $platform)
{
/**
* ToDo: Finish implementing it
*/
return new \AppBundle\Model\Raster();
}
public function convertToDatabaseValue($value, AbstractPlatform $platform)
{
return sprintf('%d, %d, %f, %f, %f, %f, %f, %f, %d', 10, 10, 0.1, 0.1, 0.1, 0.1, 0, 0, 4269);
}
public function canRequireSQLConversion()
{
return true;
}
public function convertToPHPValueSQL($sqlExpr, $platform)
{
/**
* ToDo: Finish implementing it
*/
return sprintf('AsText(%s)', $sqlExpr);
}
public function convertToDatabaseValueSQL($sqlExpr, AbstractPlatform $platform)
{
return sprintf('st_makeemptyraster(%s)', $sqlExpr);
}
}
在我的第一个意向我试图向数据库添加一个空的光栅。 除了插入或更新光栅，出现以下错误：
2) AppBundle\Tests\Entity\RasterTest::testCreateEmptyRasterAndAddBand
Doctrine\DBAL\Exception\DriverException: An exception occurred while executing 'INSERT INTO rasters (id, rast) VALUES (?, ?)' with params [2, "st_makeemptyraster(10, 10, 0.100000, 0.100000, 0.100000, 0.100000, 0.000000, 0.000000, 4269)"]:
SQLSTATE[XX000]: Internal error: 7 ERROR: rt_raster_from_wkb: wkb size (46) < min size (61)
相同的数据作为一个普通的SQL查询工作正常：
INSERT INTO rasters (id, rast) VALUES (14, st_makeemptyraster(10, 10, 0.100000, 0.100000, 0.100000, 0.100000, 0.000000, 0.000000, 4269));
INSERT 0 1
有谁有一个想法如何得到这个固定？ 谢谢
