Laravel - How to combine multiple queries as one Eloquent Query - laravel

Question

In my Laravel-5.8, I have these four queries accessng the same model:
$allLeaves = HrLeaveRequest::where('company_id', $userCompany)->whereYear('created_at', date('Y'))->count();
$pendingLeaves = HrLeaveRequest::where('leave_status', 1)->where('company_id', $userCompany)->whereYear('created_at', date('Y'))->count();
$rejectedLeaves = HrLeaveRequest::where('leave_status', 3)->where('company_id', $userCompany)->whereYear('created_at', date('Y'))->count();
$approvedLeaves = HrLeaveRequest::where('leave_status', 4)->where('company_id', $userCompany)->whereYear('created_at', date('Y'))->count();
How do I combine the four queries as one
something similar to this
$gender_unpublished_record = HrEmployee::selectRaw('count(gender_code) as count,gender_code, if (gender_code = 1, "Male", "Female") as gender')->whereNotIn('employee_code', $publishedgoals)->where('company_id', $userCompany)->where('hr_status', 0)->groupBy('gender_code')->get();
The one above only have 0 or 1. But what I want to achive takes care of everything in the table, leave_status as 1, 3 and 4
Thank you

Answer 1

in your Company Model you should have the relation:
public function HrLeaveRequests()
{
return $this->hasMany(HrLeaveRequest::class,'company_id');
}
now you could use withCount:
$value=Company::where('company_id',$userCompany)->withCount(['HrLeaveRequests as allLeaves'=>function($query){
$query ->whereYear('created_at', date('Y'));
},
'HrLeaveRequests as pendingLeaves'=>function($query){
$query->where('leave_status', 1)->whereYear('created_at', date('Y'));
},
'HrLeaveRequests as rejectedLeaves'=>function($query){
$query->where('leave_status', 3)->whereYear('created_at', date('Y'));
},
'HrLeaveRequests as approvedLeaves'=>function($query){
$query->where('leave_status', 4)->whereYear('created_at', date('Y'));
},
])->get();
