Question

我正在尝试从book_title中检索title属性，但是却得到了<built-in method title of str object at 0x7fb554f9f238>。我已将book_title作为参数传递给路线图，并在booktitle.html中分配了book_title的相应值

这是我的路线

@app.route('/search/<title>/',methods=['GET','POST'])
def btitle(title):
    book_title = db.execute("SELECT title,author,isbn from books WHERE (title LIKE :title)",params={"title":title}).fetchall()
    if request.method == 'GET':
        book_title = db.execute("SELECT title,author,isbn from books WHERE (title LIKE :title)",params={"title":title}).fetchall()
        if book_title:
            return render_template("booktitle.html",book_title=book_title)
        else:
            return render_template("error.html")
    else:
        book_title = db.execute("SELECT title,author,isbn from books WHERE (title LIKE :title)",params={"title":title}).fetchall()
        if book_title:
            return redirect(url_for("book",book_title=book_title))



@app.route('/books/<book_title>/',methods=['GET','POST'])
def book(book_title):
    if request.method == 'GET':
        return render_template("individualbook.html",book_title=book_title)

而且，这些是booktitle.html和individualbook.html的html页面

{% extends "layout.html" %}
{% block title %}
    {{ book }}
    {% endblock %}

{% block body %}
    <h1>Search results</h1>
    <ul>
    {% for book in book_title %}
        <li>
            <a href="{{ url_for('book', book_title=book_title) }}">
                {{ book.title }} 


            </a>
        </li>
    {% endfor %}
    </ul>

{% endblock %}

individualbook.html

{% extends "layout.html" %}

{% block title %}
    Book
{% endblock %}

{% block body %}
    <h1>Book Details</h1>

    <ul>

        <li>Title: {{ book_title.title }}</li>
        <li>author: {{ book_title.author }}</li>
        <li>isbn: {{ book_title.isbn }}</li>

    </ul>

{% endblock %}

当我尝试获取title，author和isbn的值时，我得到的Title:<built-in method title of str object at 0x7fb554f9f238>和author和isbn的值为空。 / p>

为什么我得到<内置方法=“” title =“” of =“” str =“” object =“” at =“” 0x7fb554f9f238 =“”>而不是值？
