Laravel 7: Calling data with a custom foreign key shows error-CodePudding

I have a department table. Here is a column name created_by. It stores the id from users table. I want to call the users name from created_by column's id. But it shows error Column not found: 1054 Unknown column 'users.department_id' in 'where clause'

Department Model:

 public function user(){
    return $this->hasMany(User::class);
}

User Model:

 public function department(){
    return $this->belongsTo(Department::class, 'created_by');
}

Controller:

 public function index(){
    $departments = Department::where('deletion_status', 0)->orderBy('department', 'asc')->get();
    return view('admin.department_manage', compact('departments'));
}

Blade file:

   @foreach($departments as $row)
       <tr>
          <td>{{ $loop->iteration }}</td>
          <td>{{ $row->user->name }}</td>
       </tr>
   @endforeach

Can anyone please help me to find out the solutions?

CodePudding user response：

you specified laravel wrong relationships. do this: for the user model departments() { return $this-> hasMany(Department::class, 'created_by')} Then for the department model: user(){return $this->belongsTo(User::class, ' created_by', 'id')}. The call would be: departments= Department::where('deletion_status', 0)->with('user')->get() Each element in the departments collection will have information about a user. , which can be obtained for example like this department -> user->name
