我已经创建了一个用于预处理POI的API，并将节点的坐标存储在“point”-type-column（MySQL）中。
当API完成并且运行没有错误时，您可以猜测我已经为CakePHP实现了Point-Type。
但现在问题是： 我想用PHPUnit测试API，但Cake \ Database \ Schema \ Table :: createSql-Method弄乱了sql。
直到Object包含点类型，但此函数创建的sql错过了数据类型。
您有什么想法可以解决丢失的类型吗？ 或者我如何在灯具中执行原始sql查询？
以下是片段和片段。数据
“节点”的灯具的$字段：
public $fields = [
'id' => ['type' => 'integer', 'length' => 11, 'unsigned' => false, 'null' => false, 'default' => null, 'comment' => '', 'autoIncrement' => true, 'precision' => null],

以及由上述shemas createSql-method生成的错误的sql-query：

[protected] _statement => object(PDOStatement) {
queryString => 'CREATE TABLE `nodes` (
`id` INTEGER(11) NOT NULL AUTO_INCREMENT,
`osm_id` BIGINT NOT NULL,
`version` BIGINT NOT NULL,
`coordinates` NOT NULL,

}
[protected] _driver => object(Cake\Database\Driver\Mysql) {

正如您所见，“坐标”缺少数据类型。

答案 0 :(得分：5)
表创建SQL支持的类型在相应的模式类中进行了硬编码。可能还有改进的余地，首先是为不支持的类型抛出异常。
干净的方法可能是创建扩展架构类并覆盖\Cake\Database\Schema\BaseSchema::columnSql()方法并相应地为point类型创建适当的SQL。
这还需要使用覆盖创建相应模式类实例的schemaDialect()方法的扩展驱动程序类。
这是MySQL演示原理的一个简单示例：
// src/Database/Driver/Mysql.php
namespace App\Database\Driver;
use App\Database\Schema\MysqlSchema;
use Cake\Database\Driver\Mysql as BaseMysql;
class Mysql extends BaseMysql
{
public function schemaDialect()
{
if (!$this->_schemaDialect) {
$this->_schemaDialect = new MysqlSchema($this);
}
return $this->_schemaDialect;
}
}
// src/Database/Schema/MysqlSchema.php
namespace App\Database\Schema;
use Cake\Database\Schema\MysqlSchema as BaseMysqlSchema;
use Cake\Database\Schema\TableSchema; // as of CakePHP 3.4
// use Cake\Database\Schema\Table as TableSchema; // before CakePHP 3.4
class MysqlSchema extends BaseMysqlSchema
{
public function columnSql(TableSchema $schema, $name)
{
$data = $schema->column($name);
if ($data['type'] === 'point') {
$out = $this->_driver->quoteIdentifier($name);
$out .= ' POINT';
if (isset($data['null']) && $data['null'] === false) {
$out .= ' NOT NULL';
}
if (isset($data['comment']) && $data['comment'] !== '') {
$out .= ' COMMENT ' . $this->_driver->schemaValue($data['comment']);
}
return $out;
}
return parent::columnSql($schema, $name);
}
}
然后只需在driver中配置数据源config/app.php选项：
'driver' => \App\Database\Driver\Mysql::class,
更简单，但也更少DRY，将覆盖TestFixture::create()类中的NodesFixture方法，并在那里执行完全自定义表创建SQL。
public function create(ConnectionInterface $db)
{
try {
$query = 'CREATE TABLE ...';
$stmt = $db->prepare($query);
$stmt->execute();
$stmt->closeCursor();
} catch (Exception $e) {
$msg = sprintf(
'Fixture creation for "%s" failed "%s"',
$this->table,
$e->getMessage()
);
Log::error($msg);
trigger_error($msg, E_USER_WARNING);
return false;
}
return true;
}
如果您需要支持不同的方言，可以检查$db->driver()并相应地创建适当的SQL。
