Laravel - How to import excel file file and save into a table with foreign keys - laravel

Question

I am using Laravel-5.8 for a web application. Also, I am using maatwebsite-3.1 to import excel file.
Model: HrEmployee
protected $table = 'hr_employees';
protected $fillable = [
'employee_code',
'user_id',
'address',
'company_id',
'email',
'line_manager_id',
'employee_designation_id',
'employee_job_title_id',
'employee_status_id',
'employee_type_id',
'employement_type_id',
'employment_date',
'first_name',
'last_name',
'is_hod'
];
public function user()
{
return $this->belongsTo('App\User');
}
public function parent()
{
return $this->belongsTo('HrEmployee', 'line_manager_id');
}
public function children()
{
return $this->hasMany('HrEmployee', 'ine_manager_id');
}
public function company()
{
return $this->belongsTo('App\Models\Organization\OrgCompany','company_id');
}
public function designation()
{
return $this->belongsTo('App\Models\Hr\HrDesignation','employee_designation_id');
}
public function jobtitle()
{
return $this->belongsTo('App\Models\Hr\HrJobTitle','employee_job_title_id');
}
public function employeestatus()
{
return $this->belongsTo('App\Models\Hr\HrEmployeeStatus','employee_status_id');
}
public function employeetype()
{
return $this->belongsTo('App\Models\Hr\HrEmployeeType','employee_type_id');
}
public function employementtype()
{
return $this->belongsTo('App\Models\Hr\HrEmployementType','employement_type_id');
}
public function department()
{
return $this->belongsTo('App\Models\Organization\OrgDepartment','department_id');
}
I have already configured the Maatwebsite Excel Package
app/Imports/EmployeesImport.php
namespace App\Imports;
use App\User;
use App\HrEmployee;
use Maatwebsite\Excel\Concerns\ToModel;
use Maatwebsite\Excel\Concerns\WithHeadingRow;
class EmployeesImport implements ToModel, WithHeadingRow
{
public function model(array $row)
{
return new HrEmployee([
'employee_code' => $row['employee_code'],
'email' => $row['email'],
'first_name' => $row['first_name'],
'last_name' => $row['last_name'],
'line_manager_id' => $row['line_manager_id'],
'employee_designation_id' => $row['employee_designation_id'],
'employee_job_title_id' => $row['employee_job_title_id'],
]);
}
}
Controller
class HrEmployeesController extends Controller
{
public function importExportView()
{
return view('import');
}
public function import()
{
Excel::import(new EmployeesImport,request()->file('file'));
return back();
}
}
How do I re-write my code to accommodate the foreign keys (line_manager_id,employee_designation_id,employee_job_title_id), so that it will map the keys to the name.
For example, if designation_name is entered to the excel sheet it should map it to employee_designation_id.
Thank you

Answer 1

Just find the foreign key ID in the EmployeesImport
$row['employee_designation_id'] = HrDesignation::where("name", "like", "%".$row['designation']."%");
$row['line_manager_id'] = HrEmployee::where("first_name", "like", "%".$row['line_manager']."%");
$row['employee_job_title_id'] = HrJobTitle::where("name", "like", "%".$row['job_title']."%");
or the full code
namespace App\Imports;
use App\User;
use App\HrEmployee;
use App\Hr\HrDesignation;
use App\Hr\HrJobTitle;
use Maatwebsite\Excel\Concerns\ToModel;
use Maatwebsite\Excel\Concerns\WithHeadingRow;
class EmployeesImport implements ToModel, WithHeadingRow
{
public function model(array $row)
{
$row['employee_designation_id'] = HrDesignation::where("name", "like", "%".$row['designation']."%");
$row['line_manager_id'] = HrEmployee::where("first_name", "like", "%".$row['line_manager']."%");
$row['employee_job_title_id'] = HrJobTitle::where("name", "like", "%".$row['job_title']."%");
return new HrEmployee([
'employee_code' => $row['employee_code'],
'email' => $row['email'],
'first_name' => $row['first_name'],
'last_name' => $row['last_name'],
'line_manager_id' => $row['line_manager_id'],
'employee_designation_id' => $row['employee_designation_id'],
'employee_job_title_id' => $row['employee_job_title_id'],
]);
}
}

Answer 2

namespace App\Imports;
use App\User;
use App\HrEmployee;
use App\Hr\HrDesignation;
use App\Hr\HrJobTitle;
use Maatwebsite\Excel\Concerns\ToModel;
use Maatwebsite\Excel\Concerns\WithHeadingRow;
class EmployeesImport implements ToModel, WithHeadingRow
{
public function model(array $row)
{
$employee_designation = HrDesignation::where("name", "like", "%".$row['designation']."%")->first();
$line_manager = HrEmployee::where("first_name", "like", "%".$row['line_manager']."%")->first();
$employee_job_title = HrJobTitle::where("name", "like", "%".$row['job_title']."%")->first();
$row['employee_designation_id'] = $employee_designation->id;
$row['line_manager_id'] = $line_manager->id;
$row['employee_job_title_id'] = $employee_job_title->id;
return new HrEmployee([
'employee_code' => $row['employee_code'],
'email' => $row['email'],
'first_name' => $row['first_name'],
'last_name' => $row['last_name'],
'line_manager_id' => $row['line_manager_id'],
'employee_designation_id' => $row['employee_designation_id'],
'employee_job_title_id' => $row['employee_job_title_id'],
]);
}
}
