Laravel 搜索查询

Question

我正在尝试执行搜索查询，搜索服务标题、描述和公司名称（公司有服务，如果公司名称匹配，它 returns 服务）。

我有一个搜索字段，它被传递到我的控制器。我试过这样：

$query = Service::select('id','company_id','title','description',price);
$search = $request->input('search',null);
$query = is_null($search)  ? $query : $query->where('title','LIKE','%'.$search.'%')->orWhere('description','LIKE','%'.$search.'%')->orWhereHas('company', function ($q) use ($search)
    {
        $q->where('name','LIKE','%'.$search.'%')->get();
    });


$services= $query->paginate(5);

但是我得到一个错误，Unknown column 'services.company_id' in 'where clause' (SQL: select * from companies where services. company_id = companies.id 和 name LIKE %xx% 并且 companies.deleted_at 为空）

我该如何搜索？

谢谢！

更新：

class Service extends Model
{
use SoftDeletes;

protected $dates = ['deleted_at'];

public function company () {

    return $this->belongsTo('Company');

}
}

class Company extends Model
{
    use SoftDeletes;

    protected $dates = ['deleted_at'];

    public function services() {
    return $this->hasMany('Service');
}
}

Schema::create('services', function (Blueprint $table) {
        $table->increments('id');
        $table->integer('company_id');
        $table->integer('service_category_id');
        $table->integer('server_id');
        $table->string('title');
        $table->string('description');
        $table->string('icon');
        $table->boolean('accepts_swaps');
        $table->integer('qty_available');
        $table->double('price_usd', 10, 6);
        $table->timestamps();
        $table->softDeletes();
    });

Schema::create('companies', function (Blueprint $table) {
        $table->increments('id');
        $table->integer('owner_id');
        $table->string('name');
        $table->string('email');
        $table->string('paypal_email')->nullable();
        $table->string('skrill_email')->nullable();
        $table->string('contact_email')->nullable();
        $table->string('phone')->nullable();
        $table->integer('city_id')->nullable();
        $table->string('short_description')->nullable();
        $table->text('description')->nullable();
        $table->integer('subscription_id')->nullable();
        $table->timestamp('subscription_end_date')->nullable();
        $table->string('avatar')->default("img/default/user-avatar-128.min.png");
        $table->integer('highlighted_game_id')->nullable()->default(null);
        $table->timestamps();
        $table->softDeletes();
    });

Answer 1

where 子句中的 get 函数导致了问题。尝试删除 get.

因此您的代码将如下所示：

$query = Service::select('id','company_id','title','description',price);
$search = $request->input('search',null);
$query = is_null($search)  ? $query : $query->where('title','LIKE','%'.$search.'%')->orWhere('description','LIKE','%'.$search.'%')->orWhereHas('company', function ($q) use ($search)
    {
        $q->where('name','LIKE','%'.$search.'%');
    });


$services= $query->paginate(5);
