Property [id] does not exist on this collection instance

Question

I am trying to create edit page and this error keeps popping up Whoops, looks like something went wrong. Property [id] does not exist on this collection instance.

Answer 1

The error is here:

$books->id

When you're using get() you get a collection and $books is a collection. In this case you need to iterate over it to get its properties:

@foreach ($books as $book)
    {{ $book->id }}
@endforeach

Answer 2

You have to retrieve one record with first() not a collection with get(), i.e:

$book = $this->bookModel
    ->join('author', 'author.id', '=', 'book.author_id')
    ->where('book.id', '=', $id)
    ->select('book.*', 'author.name_1 as authorname1')
    ->first();

Please sobstitute $books with $book in the rest of the code also.

Answer 3

I think your code need to update like:

$books = $this->bookModel
       ->join('author', 'author.id', '=', 'book.author_id')
       ->where('book.id', '=', $id)
       ->select('book.*', 'author.name_1 as authorname1')
       ->first();
   return view('backend.book.edit', compact('books'));

Hope this work for you!

Answer 4

As Mayank mentioned above you get a collection, you neeed to itreate over the FIELDS to get the right field you want. I am giving the same answer in the sytax which is working for me

foreach ($books as $book) {
     $book_id = $book->id
}
