I am trying to get all books that match my several book_ids, but instead I only get one of the books.

books =  mydb.Book.find({"book_id ": book_id})

CodePudding user response：

You can use $in to find all the documents that match any value in your list book_ids

see the doc

books =  mydb.Book.find({"book_id": {"$in": book_ids}})

I solved my problem,
listBooks=[] listBooks.append(book_id)
