New version features

Controller middleware improvements

Since in Swoole and other modes, the class library is resident in memory, control The controller middleware will not be executed the second time, and now the execution process of the controller middleware is no longer included in the architecture function.

Model improvements

Improved the judgment logic of whether the modifier is executed. If the modifier method is not defined, multiple assignments to model data are allowed. In this way, data can be easily modified in model events.

The fields of aggregation queries support the use of DISTINCT, for example:

User::count('DISTINCT id');

When associated aggregation queries use closures, the specified aggregation fields are supported

User::withCount(['book' => function($query){
    // 统计今年出版的书的数量 并且使用books_num作为统计字段返回
    $query->whereTime('publish_time', 'y');
    return 'books_num';
})->select();

For many-to-many relationships, you can also Supports the following usage

use think\Model;
class User extends Model{
    public function roles()
    {
        // 使用pivotDataName方法指定中间表的数据对象名称
        return $this->belongsToMany('role')
            ->pivotDataName('userRole');
    }
}

$user =  User::get(1);
$role =  Role::getByName('editor');
// 判断关联数据是否存在 如果存在则返回中间表对象
$pivot = $user->roles()->attached($role);

and also fixes the error caused when the fetchSql method is used in related queries.

Improvements in validation rules

If closures are used in validation rules, you can now add additional parameters, including

// 新增的参数包括title（规则标题）和validate（当前验证对象）
function($value, $data, $title, $validate) {}

Added beforeWith and afterWith two validation rules for comparing data from multiple date fields.

$validate = Validate::make([
    'start_time'   => 'require|beforeWith:end_time',
    'end_time'     => 'require|afterWith:start_time'
]);
if (!$validate->check($data)) {
    dump($validate->getError());
}
