Attempt to read property "email" on int - Laravel 8

Question

I have a Work model where one of its attributes is the requestor, I am trying to obtain the requestor´s data (I can already obtain the primary key).

In this way I call the view:

$obras = Obra::all();
return view("obra.index", compact("obras"));

The view:

@forelse ($obras as $i)
  <li>{{ $i->requestor_id->email }}</li>
@empty

The relationship in the work model:

public function requestor_id() {
    return $this->hasOne(User::class);
}

Tables:

Users (applicants)
- id
- name
- email
- password

Work
- id
- user_id
- start_date

Answer 1

The problem seems to be that I had the relations wrong, I had to use hasOne in the requester model (in the end I used hasMany because someone can create more than one work) and in the work model use belongsTo.

IMPORTANT note: the name of the function in the model cannot be the same as the name of a field in your table. Also in my case the column names do not follow the laravel/eloquent nomenclature so another parameter is added to belongsTo with the field name.

Work model:

public function solicitante() {
    return $this->belongsTo(User::class, "requestor_id");
}

Requestor model:

public function obra() {
    return $this->hasMany(Obra::class, "requestor_id");
}

And how to obtain requester data: $obra->solicitante->email
