我有这3张桌子:
Schema::create('companies', function (Blueprint $table) {
$table->increments('id');
$table->integer('city_id')->unsigned();
$table->string('name');
$table->string('address');
$table->float('lat', 10,6);
$table->float('lng', 10,6);
$table->timestamps();
$table->foreign('city_id')->references('id')->on('cities');
});
Schema::create('company_clients', function (Blueprint $table) {
$table->increments('id');
$table->integer('company_id')->unsigned();
$table->integer('client_id')->unsigned();
$table->foreign('company_id')->references('id')->on('companies');
$table->foreign('client_id')->references('id')->on('companies');
});
Schema::create('cities', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
});
现在,我希望有一个雄辩的查询,它将返回一个公司的数组(不仅仅是一个项目),其中(例如)company_clients表上的(例如)company_id = 1。此外,city_id假设使用cities表返回名称而不是id。我无法想象现在该怎么做。 我做了:
class City extends Model
{
protected $table = 'cities';
public $timestamps = false;
protected $fillable = [
'name',
];
public function companies()
{
return $this->hasMany('App\Company', 'city_id', 'id');
}
}
class CompanyClients extends Model
{
protected $table = 'company_clients';
public $timestamps = false;
protected $fillable = [
'company_id', 'client_id',
];
public function companies()
{
return $this->belongsTo('App\Company', 'company_id', 'id');
}
public function clients()
{
return $this->belongsTo('App\Company', 'company_id', 'id');
}
}
class Company extends Model
{
protected $table = 'companies';
protected $fillable = [
'name', 'address', 'lat', 'lng', 'city_id',
];
protected $hidden = [
'clients', 'created_at', 'updated_at',
];
public function city()
{
return $this->belongsTo('App\City', 'city_id', 'id');
}
public function companies()
{
return $this->hasMany('App\CompanyClients', 'company_id', 'id');
}
public function clients()
{
return $this->hasMany('App\CompanyClients', 'client_id', 'id');
}
}
但是,我错过了控制器中的代码。我试过了:
$result = Company::leftJoin('company_clients', function($join) {
$join->on('companies.id', '=', 'company_clients.company_id');
})->where('company_clients.company_id', '=', 1 )->get();
或
$result = Company::with(['clients' => function($q){
$q->where('company_id', 1);
}])->get();
但未返回正确的结果。我缺少什么?
谢谢!
EDITED: 我找到了一种方法,但我不确定这是否是最好的方法。有人可以确认吗?
$result = Company::join('company_clients', function($join) {
$user = Auth::guard('api')->user();
$join->on('companies.id', '=', 'company_clients.client_id')->where('company_clients.company_id', '=', $user->company_id );
})->join('cities', 'cities.id', '=', 'companies.city_id')->get(array('companies.*', 'cities.name'));
答案 0 :(得分:0)
尝试
CompanyClients::with('company.city', 'clients')->where('company_id', 1)->get();
重命名
公司
将CompanyClients模型与
的关系公司
