让我们快速看一下 Laravel 4 的以下Model类,我们刚刚从中扩展出来的(位于Vendor\Laravel\Framework\src\Illuminate\Database\Eloquent文件夹中): <?phpnamespaceIlluminate\Database\Eloquent;useDateTime;useArrayAccess;useCarbon\Carbon;useLogicException;useJsonSerializable;useIlluminate\Events\Dispatcher;useIlluminate\Dat...
components−>sort( sort和search方法都不是Laravel自带的Model方法,这种情况一般是自定义的scope。scope是定义在Model中可以被重用的方法,他们都以scope开头。我们可以在app/Models/Traits/SortableTrait.php中找到scopeSort方法: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 trait SortableTrait{/** * Adds ...

Scopes 允许您轻松地在模型中复用查询逻辑。要定义 scope，只需在模型方法的前面加上 scope：classUserextendsModel{publicfunctionscopePopular($query){return $query->where('votes','>',100);}publicfunctionscopeWomen($query){return $query->whereGender('W');}}用法:$users = User::popular()->women()...
但使用model实例查询node,scope自动基于设置的限制作用域属性来删选node。例如: $node = MenuItem::findOrFail($id); $node->siblings()->withDepth()->get(); // OK 使用实例来获取删选的查询: $node->newScopedQuery(); 注意,当通过主键获取模型时不需要使用scope ...
于是我就在BaseModel中定义了: // 多where public function scopeMultiwhere($query, $arr) { if (!is_array($arr)) { return $query; } foreach ($arr as $key => $value) { $query = $query->where($key, $value); } return $query; ...
