首先我们将创建一下基础目录，如下图所示
```
admin模块
|- controller
command 命令行目录
model 模型目录
traits trait目录
validate 验证目录
view 目录直接单独放在根目录下，本人习惯而已
```
因为 view 目录在根目录下面，所以要做一些改变，首先修改配置文件 template.php
```
// 模板路径
'view_path' => env('root_path') . 'view' . DIRECTORY_SEPARATOR,
```
然后需要重写 fetch 方法，再次基础上所以必须建立 基类控制器, admin\controller\Base.php
```
namespace app\admin\controller;
use think\Controller;
class Base extends Controller
{
protected $vars;
protected function fetch($template = '', $vars = [], $config = [])
{
$template = strtolower($this->request->module()) . DIRECTORY_SEPARATOR . strtolower($this->request->controller()) . DIRECTORY_SEPARATOR . ($template ? $template : strtolower($this->request->action()));
if (count($this->vars)) {
$vars = array_merge($vars, $this->vars);
}
return $this->view->fetch($template, $vars, $config);
}
// 这里是为了属性的赋值模板分配
public function __set($name, $value)
{
// TODO: Implement __set() method.
$this->vars[$name] = $value;
}
}
```
### 另外一种方法
```
'view_base' => env('root_path') . 'views' . DIRECTORY_SEPARATOR, // 直接添加 view_base 配置就可以了
```
这样就可以开始了。
### 创建基类模型
这里创建抽象模型 application\model\AbstractBase.php， 约定必须实现其中的四个抽象方法，以及约定模型文件必须以Model结尾
```
namespace app\model;
use think\Model;
use think\db\Where;
abstract class AbstractBase extends Model
{
// 时间戳自动更新
protected $autoWriteTimestamp = 'datetime';
protected $createTime = 'created_at';
protected $updateTime = false;
public function initialize()
{
parent::initialize();
// 这里为了简化模型使用，所以这里就讲自动设置表名
$m = explode('\\', get_called_class());
$modelName = array_pop($m);
if (strpos($modelName, 'Model') !== false) {
$this->name = substr($modelName, 0, -strpos($modelName, 'Model')-1);
}
}
// 以下是必须实现的四个方法
public abstract function store($data);
public abstract function updateBy($id, $data);
public abstract function findBy($id);
public abstract function deleteBy($id);
public function conditions($where)
{
return (new Where($where));
}
}
```
## view的编写
后台模块用的是这个 [https://download.csdn.net/download/qq_31470439/10707283]() 还是挺好看的。有兴趣的可以下载使用,还需要**ajaxform**和**sweetalert**插件
创建一个基类模板 view\admin\public\base.html
```

此后模板文件都会继承这个基类模板。
