Laravel FirstOrCreate Method returned Column not found - laravel

Question

I am trying to check if data exist in a table before saving. I can save to the table
public function read($book_id)
{
MyBook::create([
'book_id' => $id,
'user_id' => Auth::id()
]);
$readBooks = Book::where('id', $book_id)->get()->first();
return view('read')->with('data', $readBooks);
}
But when I tried to use firstOrCreate to check before saving it returned this error
SQLSTATE[42S22]: Column not found: 1054 Unknown column '1' in 'where
clause' (SQL: select * from my_books where (1 is null and 1 is
null) limit 1)
This is the method I am using
public function read($book_id)
{
$mybook = MyBook::firstOrCreate([
['book_id' => $book_id],
['user_id' => Auth::id()]
]);
$readBooks = Book::where('id', $book_id)->get()->first();
return view('read')->with('data', $readBooks);
}
My my_book table schema
public function up()
{
Schema::create('my_books', function (Blueprint $table) {
$table->bigIncrements('id');
$table->integer('book_id')->unsigned();
$table->integer('user_id')->unsigned();
$table->timestamps();
});
}
I don't know what I am doing wrong, I hope I can find help here.Thanks.

Answer 1

You are passing array inside it also 2 array. But that is not correct. You must be use like this
$mybook = MyBook::firstOrCreate(
['book_id' => $book_id],
['user_id' => Auth::id()]
);

Answer 2

You are passing a single array of arrays as the first argument to firstOrCreate. It takes associative arrays for the arguments.
$mybook = MyBook::firstOrCreate(
['book_id' => $book_id],
['user_id' => Auth::id()]
);
Argument 1 and 2 are associative arrays.
