Laravel Eloquent 查询生成器默认 Where 条件

Laravel Eloquent Query Builder Default Where Condition(Laravel Eloquent 查询生成器默认 Where 条件)

问题描述

我有新闻模型，当我查询新闻时，我希望它带来默认状态 = 1 的新闻.

I have News model, when i query news, i want it brings news where status = 1 as default.

News::all(); // select * from news where status = 1
News::where('anotherColumn',2)->get(); // select * from news where status = 1 and where category = 2

这可能吗?我想要的与软删除功能非常相似(它在 deleted_at 不为空的地方，如果所有数据都需要 withTrashed 功能可以使用).

Is this possible? What i want is so similar to soft delete feature (it gets where deleted_at is not null and if all data is wanted withTrashed function can be used).

我查看了文档，但找不到任何有用的信息.另外，我尝试在 News 模型的构造中处理它，但它也没有工作.

I looked docs but i couldn't find anything helpful. Also, i tried to handle it in construct at News model but it didn't worked either.

谢谢.

推荐答案

我通常会为此重写 newQuery().newQuery() 是 Eloquent 用来构造新查询的方法.

I normally override newQuery() for this. newQuery() is the method that Eloquent use to construct a new query.

class News extends Eloquent {

    public function newQuery($excludeDeleted = true) {
        return parent::newQuery($excludeDeleted)
            ->where(status, '=', 1);
    }

}

现在您的 News::all() 将只输出您的状态 = 1 的新闻.

Now your News::all() will only output your news with status = 1.
