Question

我是PHP和CakePHP的新手。使用CakePhp连接数据库时发现问题。

以下是我的应用配置。我在Bitnami WAMP堆栈5.4.40-0 我正在使用CakePhp 3.0.4来创建一个web mvc应用程序

在我的app.php文件中输入数据源

/**
 * Connection information used by the ORM to connect
 * to your application's datastores.
 * Drivers include Mysql Postgres Sqlite Sqlserver
 * See vendor\cakephp\cakephp\src\Database\Driver for complete list
 */
'Datasources' => [
    'default' => [
        'className' => 'Cake\Database\Connection',
        'driver' => 'Cake\Database\Driver\Mysql',
        'persistent' => false,
        'host' => 'localhost',
        /**
         * CakePHP will use the default DB port based on the driver selected
         * MySQL on MAMP uses port 8889, MAMP users will want to uncomment
         * the following line and set the port accordingly
         */
        //'port' => 'nonstandard_port_number',
        'username' => 'test2',
        'password' => 'computer',
        'database' => 'jobs',
        'encoding' => 'utf8',
        'timezone' => 'UTC',
        'cacheMetadata' => true,

        /**
         * Set identifier quoting to true if you are using reserved words or
         * special characters in your table or column names. Enabling this
         * setting will result in queries built using the Query Builder having
         * identifiers quoted when creating SQL. It should be noted that this
         * decreases performance because each query needs to be traversed and
         * manipulated before being executed.
         */
        'quoteIdentifiers' => false,

        /**
         * During development, if using MySQL < 5.6, uncommenting the
         * following line could boost the speed at which schema metadata is
         * fetched from the database. It can also be set directly with the
         * mysql configuration directive 'innodb_stats_on_metadata = 0'
         * which is the recommended value in production environments
         */
        //'init' => ['SET GLOBAL innodb_stats_on_metadata = 0'],
    ],

我可以使用bake命令生成基本的锅炉板代码

但现在我在localhost中运行我的应用程序：8765 / myapp

我收到以下错误

2015-07-01 14:31:22 Error: [RuntimeException] Unable to locate an object compatible with paginate.

请求网址：/ myjobs

我的控制器代码

}

还想知道位于端口8765中的内部服务器位于何处。？我想使用eclipse在这个服务器上调试资源。

Answer 1

键入错误的网址时会发生此错误：

它应该是

之一

localhost:8765/my-app   
localhost:8765/myApp 
localhost:8765/my_app

但不是：localhost：8765 / myapp

Answer 2

我想我的桌面结构存在一些问题。

可能CakePHP在表中查找某些属性。特别是作为主键的id的自动增量属性。

我根据书签表创建了我的表结构，并且它有效。

我有一个枚举字段，它没有通过CakePHP映射到对象。我想枚举是CakePHP的限制。

此致

无法找到与paginate兼容的对象。使用CakePHP
