Den*_*ter 4 php mysql phpunit cakephp
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.
由于API已完成并且运行没有错误,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搞砸了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？或者我如何在夹具中执行原始sql查询？
以下是摘要和数据
"节点"夹具的$字段:
public $fields = [
'id' => ['type' => 'integer', 'length' => 11, 'unsigned' => false, 'null' => false, 'default' => null, 'comment' => '', 'autoIncrement' => true, 'precision' => null],
'osm_id' => ['type' => 'biginteger', 'length' => 20, 'unsigned' => false, 'null' => false, 'default' => null, 'comment' => '', 'precision' => null, 'autoIncrement' => null],
'version' => ['type' => 'biginteger', 'length' => 20, 'unsigned' => false, 'null' => false, 'default' => null, 'comment' => '', 'precision' => null, 'autoIncrement' => null],
'coordinates' => ['type' => 'point', 'length' => null, 'null' => false, 'default' => null, 'collate' => null, 'comment' => '', 'precision' => null],
'category' => ['type' => 'string', 'length' => 255, 'null' => false, 'default' => null, 'collate' => 'utf8_general_ci', 'comment' => '', 'precision' => null, 'fixed' => null],
'created' => ['type' => 'timestamp', 'length' => null, 'null' => false, 'default' => 'CURRENT_TIMESTAMP', 'comment' => '', 'precision' => null],
'modified' => ['type' => 'timestamp', 'length' => null, 'null' => true, 'default' => null, 'comment' => '', 'precision' => null],
'_constraints' => [
'primary' => ['type' => 'primary', 'columns' => ['id'], 'length' => []],
],
'_options' => [
'engine' => 'InnoDB',
'collation' => 'utf8_general_ci'
],
];

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

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

如您所见,"坐标"缺少数据类型.

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,从为不支持的类型抛出异常开始.
一种干净的方法可能是创建扩展的模式类并覆盖该\Cake\Database\Schema\BaseSchema::columnSql()方法并相应地为该point类型创建适当的SQL .
这还需要使用覆盖schemaDialect()创建相应模式类实例的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);
}
}
然后只需相应地配置数据源driver选项config/app.php:
'driver' => \App\Database\Driver\Mysql::class,
更简单,但也更少DRY,将覆盖TestFixture::create()您的NodesFixture类中的方法,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($msg, E_USER_WARNING);
return false;
}
return true;
}
如果您需要支持不同的方言,则可以$db->driver()相应地检查并创建适当的SQL.
