The geometry_type of a spatial column cannot be changed

[ghost]

I use SF2.7 , and when try to make
app/console doctrine:migrations:diff and got such exception
i debug these code and have

class Doctrine\DBAL\Schema\ColumnDiff#1308 (4) {
public $oldColumnName =>
string(14) "location_point"
public $column =>
class Doctrine\DBAL\Schema\Column#1223 (16) {
protected $_type =>
class Jsor\Doctrine\PostGIS\Types\GeographyType#529 (0) {
}
protected $_length =>
NULL
protected $_precision =>
int(0)
protected $_scale =>
int(0)
protected $_unsigned =>
bool(false)
protected $_fixed =>
bool(false)
protected $_notnull =>
bool(true)
protected $_default =>
NULL
protected $_autoincrement =>
bool(false)
protected $_platformOptions =>
array(1) {
'version' =>
bool(false)
}
protected $_columnDefinition =>
NULL
protected $_comment =>
NULL
protected $_customSchemaOptions =>
array(4) {
'spatial_type' =>
string(5) "POINT"
'spatial_srid' =>
int(4326)
'geometry_type' =>
string(8) "GEOMETRY"
'srid' =>
int(4326)
}
protected $_name =>
string(14) "location_point"
protected $_namespace =>
NULL
protected $_quoted =>
bool(false)
}
public $changedProperties =>
array(3) {
[0] =>
string(13) "geometry_type"
[1] =>
string(12) "spatial_type"
[2] =>
string(12) "spatial_srid"
}
public $fromColumn =>
class Doctrine\DBAL\Schema\Column#792 (16) {
protected $_type =>
class Jsor\Doctrine\PostGIS\Types\GeographyType#529 (0) {
}
protected $_length =>
NULL
protected $_precision =>
int(10)
protected $_scale =>
int(0)
protected $_unsigned =>
bool(false)
protected $_fixed =>
bool(false)
protected $_notnull =>
bool(true)
protected $_default =>
NULL
protected $_autoincrement =>
bool(false)
protected $_platformOptions =>
array(0) {
}
protected $_columnDefinition =>
NULL
protected $_comment =>
NULL
protected $_customSchemaOptions =>
array(2) {
'geometry_type' =>
string(5) "POINT"
'srid' =>
int(4326)
}
protected $_name =>
string(14) "location_point"
protected $_namespace =>
NULL
protected $_quoted =>
bool(false)
}
}

and my entity

/**

• @Orm\Embeddable
  /
  class Coordinates
  {
  /*
  • @var string
  • @Orm\Column(type="geography", options={"spatial_type"="POINT", "spatial_srid"=4326})
    */
    private $point;

Why i receive such exception and how to fix it?

Unfortunately, spatial column types can't be changed because there is no way to cast data from one geometry to another. If you already have a spatial column in your database, you need to change the type and convert the data manually.
