laravel auth() is not allowing a user to make a post request - php

Question

A user should be able to set a rating for more than one book, it allows a user to set a rating for ONLY one book, but not any other.
The problem
the user is not able to make another rating for
another book. However, another user
can make a rating for the same book, but cant make another rating for
other books. Not even if the user logged out.
I'm using rateYo and laravel-ratable
The way i have it set up, a rating type is set to false by default, enabling a user to set stars and make a rating pretty much.
And once again, once a user makes a rating for any book doesn't matter which, the rating type is set to true which disables a user to set a star.
Here is what i have
here is how the html setup is like
HTML
<div id="rateYo" data-rateyo-rating="{{ $book->userSumRating or 0}}" data-rateyo-read-only="{{ $book->rated ? 'true' : 'false' }}"></div`>
BookController.php
public function rate(Request $request, $book_id)
{
$book = Book::find($book_id);
$rating = $book->ratings()->where('user_id', auth()->user()->id)->first();
if(is_null($rating)){
$ratings = new Rating();
$ratings->rating = $request['rating'];
$ratings->user_id = auth()->user()->id;
$ratings->type = Book::RATED;
$book->ratings()->save($ratings);
return json_encode($book);
}
else{
return response()->json(['status' => 'You already left a review']);
}
}
public function show($book_name)
{
$books = Book::GetBook($book_name)->get();
$data = $books->map(function(Book $book){
$book['rated'] = $book->type;
return $book;
});
return view('books.show', compact('data', $data));
}
Book.php(relevant code) On default if a rating has not been set, type is equal to false enabling the user to make a rating, if a rating is set, type is equal to true disabling the star feature/read mode.
use Rateable;
const RATED = "true";
const NOT_RATED = "false";
protected $fillable = [ 'user_id', 'title', 'description'];
protected $appends = ['rated'];
public function getRatedAttribute()
{
return Rate::where('type', $this->owl() )->where('user_id', auth()->user()->id )->first();
}
public function owl(){
foreach($this->rate as $rates){
if ($rates->type != "true"){
return self::NOT_RATED;
}
}
return self::RATED;
}
public function rate()
{
return $this->hasMany('App\Rate', 'type', 'user_id');
}

Answer 1

You need to add the book id in the where clause to check if the user has left a rating for that particular book. As you have it it will find the first rating a user has left for any book.
$constraints = [
'user_id' => auth()->id(),
'book_id' => $book_id
];
// checks if the user has not left a rating for this particular book
if ($book->ratings()->where($constraints)->doesntExist()) {
// create new rating...
} else {
// user has already rated this book...
}

i need to change my Book model to the following, thank you digital for steering me into the right direction
Book.php
public function getRatedAttribute()
{
$this->constraints = [
'user_id' => auth()->id()
];
if(Rating::where($this->constraints)->exists()){
return Rating::where(['type' => self::RATED, 'book_id' => $this->getKey()])->first();
}else{
return Rating::where('type' ,self::NOT_RATED)->first();
}
}
