How to query a customize key in Laravel? - php

Question

Considering this tables: person and employee to which connected to person by person_id. This person_id is also the Primary & Foreign key of employee table. Thus in my migrations, i have this:
Schema::create('employees', function (Blueprint $table) {
$table->bigIncrements('person_id');
$table->foreign('person_id')->references('id')->on('persons')->onDelete('cascade');
});
and my show method is like this one
public function show(Employee $employee){
dd($employee->person_id);
$employee = Employee::where('person_id', $employee->person_id)->orderBy('employee_number', 'asc')->join('persons', 'employees.person_id', '=', 'persons.id')->first();
return view('employee.show', compact('employee'));
}
But i am experiencing this issue:
Illuminate\Database\QueryException
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'id' in 'where clause' (SQL: select * from `employees` where `id` = 5 limit 1)
Does the query is not aware of the column i am using?

Answer 1

Change the primary key in the Employee model
class Employee extends Model
{
/**
* The primary key associated with the table.
*
* #var string
*/
protected $primaryKey = 'person_id';
public function person()
{
return $this->belongsTo('App\Employee', 'person_id', 'person_id');
}
}
Then query using find
Employee::find($employee->person_id)->with('person')->first();
orderBy and first are redundant on one result queries
And if you want to return the Employee with the Person, just access the relationship object (employee is returned from route model binding)
public function show(Employee $employee) {
$person = $employee->person;
return view('employee.show', compact('employee', 'person'));
}
Hope this helps
