我在job_seeker和job_offer之间有很多关系(数据透视表=“ job_seeker_job_offer) 我有一个页面,该页面显示特定雇主的所有工作机会,以及如何检索附加到特定job_offer上的job_seeker的人数
显示工作提供的功能
public function show_jobs($id){
// $categories=Category::all();
$job_offer_all=Job_offer::all();
$employer=Employer::find($id);
$job_offers=Job_offer::where('employer_id',$employer_id)->with('employer')->get();
return view('employer.my_jobs',compact('employer_id','employer','job_offers','n_applicant'));
}
将求职者与求职者联系起来的功能
public function send_offer($id,$employer_id,$offer_id){
$job_seeker=Job_seeker::find($id);
$job_offer=Job_offer::find($offer_id);
$employer=Employer::find($employer_id);
// Notification::route('mail', $employer->email)
// ->notify(new submit_job_demand($job_seeker));
$job_seeker->job_offer()->attach($job_offer->id);
}

假设您已经在两个方向上建立了关系,则可以使用withCount
方法来计算关系:
$jobOffers = JobOffer::where('employer_id', $employer_id)
->withCount('job_seekers')
->with('employer')
->get();
foreach ($jobOffers as $offer) {
echo $offer->job_seekers_count;
}
