SQLAlchemy database query filter_by does not work

Question

I am trying to select a certain 'book' from the books table and pass it to the next page on flask. However, it seems like I could not use the filter. Here is what the print statement says:

SELECT books.id AS books_id, books.title AS books_title, books.summary AS books_summary FROM books WHERE books.title = ?

Thanks for the help!

class Book(db.Model):
    __tablename__ = "books"
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(100), unique=False)
    summary = db.Column(db.String(100), unique=False)

@app.route('/singlepage/<name>', methods=["GET", "POST"])
def singlepage(name):
    print(name)
    selected_book = Book.query.filter_by(title=name)

    print(selected_book)
    return render_template("singlepage.html", name=name, summary=selected_book)
