数据库配置错误 - 虽然我已设置设置并添加了文件

Question

如果您要浏览我的网站，您会看到我有数据库连接问题。我收到CakePHP的错误消息，告诉我文件丢失了。我已经检查了好几次，而且我正在使用cakePHP3。我一定搞砸了，但我不想重新开始如果你要查看我的代码：

 * Database configuration class.
 * You can specify multiple configurations for production, development and testing.
 *
 * datasource => The name of a supported datasource; valid options are as follows:
 *      Database/Mysql      - MySQL 4 & 5,
 *      Database/Sqlite     - SQLite (PHP5 only),
 *      Database/Postgres   - PostgreSQL 7 and higher,
 *      Database/Sqlserver  - Microsoft SQL Server 2005 and higher
 *
 * You can add custom database datasources (or override existing datasources) by adding the
 * appropriate file to app/Model/Datasource/Database. Datasources should be named 'MyDatasource.php',
 *
 *
 * persistent => true / false
 * Determines whether or not the database should use a persistent connection
 *
 * host =>
 * the host you connect to the database. To add a socket or port number, use 'port' => #
 *
 * prefix =>
 * Uses the given prefix for all the tables in this database. This setting can be overridden
 * on a per-table basis with the Model::$tablePrefix property.
 *
 * schema =>
 * For Postgres/Sqlserver specifies which schema you would like to use the tables in. Postgres defaults to 'public'. For Sqlserver, it defaults to empty and use
 * the connected user's default schema (typically 'dbo').
 *
 * encoding =>
 * For MySQL, Postgres specifies the character encoding to use when connecting to the
 * database. Uses database default not specified.
 *
 * unix_socket =>
 * For MySQL to connect via socket specify the `unix_socket` parameter instead of `host` and `port`
 *
 * settings =>
 * Array of key/value pairs, on connection it executes SET statements for each pair
 * For MySQL : http://dev.mysql.com/doc/refman/5.6/en/set-statement.html

我不知道为什么Cake没有识别我的文件。我已将文件正确放置在它应该位于的目录中。我记得尝试使应用程序在共享主机上工作，这就是我的Cake 2可能会被引入的方式。我被困了，伙计们。
