php - Doctrine 的 addColumn() 迁移方法有哪些选项？

Question

API 给出的代码如下：

public function up()
{
    $this->addColumn('table_name', 'column_name', 'string', $options);
}

但是没有关于选项数组中可以包含的内容的文档。

Answer 1

For people coming in: it looks like this is really defined from the Data Access Layer. Here is the list of options for columns from the DBAL docs: http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/schema-representation.html

Answer 2

文档是错误的。查看Doctrine/Migration/base.php，可以看到如下函数原型：

/**
 * Add a add column change.
 *
 * @param string $tableName Name of the table
 * @param string $columnName Name of the column
 * @param string $type Type of the column
 * @param string $length Length of the column
 * @param array $options Array of options for the column
 * @return void
 */
public function addColumn($tableName, $columnName, $type, $length = null, array $options = array())

因此，要添加长度，请将其作为第四个参数。我暂时忽略了这些选项。

按照顶部的“浏览代码”链接，您可以按照代码到$options['length']inDoctrine_Migration_Base::column()和第二个参数 in Doctrine_Migration_Base::_addChange()。不时查看源代码，它为您提供概述:)
