所以我有这个mongodb数据，我想循环这个。我正在使用 flask_pymongo，但我不能将 mongodb 数据用作 python 字典。

mongodb数据作为字典列表

[{'_id': ObjectId('5d7fa9f7d760eb306123be52'), 'bookname': 'biology book', 'bookdesc': 'my bio book', 'donatedby': 'rajesh gupta'}, {'_id': ObjectId('5d7facb59ee3d15c54b059e4'), 'bookname': 'biology book', 'bookdesc': 'my bio book', 'donatedby': 'rajesh gupta'}, {'_id': ObjectId('5dea368b9654591293f35745'), 'bookname': 'biology book', 'bookdesc': 'its my biology book', 'donatedby': 'iamuser'}, {'_id': ObjectId('5dea382d9654591293f35746'), 'bookname': 'biology book', 'bookdesc': 'damn son\r\n', 'donatedby': 'iamuser'}, {'_id': ObjectId('5dea382d9654591293f35747'), 'bookname': 'biology book', 'bookdesc': 'damn son\r\n', 'donatedby': 'iamuser'}]

到目前为止我的代码

@app.route('/request books', methods=['GET', 'POST'])
@app.route('/get books', methods=['GET', 'POST'])
def requesting_for_books():
    form = RequestBooks()
    if 'email' in session and request.method == 'GET':
        return render_template('get_books.html', title="Get Books", donated_by=session['username'], form=form)
    elif 'email' in session and request.method == 'POST':
        requesting = mongo.db.mylogin
        Requesting_books = requesting.find({'bookname': request.form['bookname']})
        x  = []
        for i in Requesting_books:
            x.append(i)
            real_data = x
            for j in x:
                h = j
        if Requesting_books == None:
            flash("Please enter a search query !")
            return render_template('get_books.html', title='Get Books', form=form)
        else:
            return render_template('get_books.html', title="Get Books", x=x, h=h, form=form)
    else:
        flash('Please Login/Sign Up first to Search for books !')
        return redirect(url_for('home'))

所以我将 mongodb 数据转换为字典列表。基本上我想获取所有的键值对，但是每当我遍历数据时，我都会得到第一个这样的字典{'_id': ObjectId('5dea382d9654591293f35747'), 'bookname': 'biology book', 'bookdesc': 'damn son\r\n', 'donatedby': 'iamuser'} 。我想要所有这些。我怎么做 ？？

更新代码

get_books.html

我想要的是，我想在我的引导卡中显示那些bookname、donatedby和bookdesc值。所以条件是，如果我的数据库中有用户正在搜索的书。我想显示有关这本书的所有信息。

引导 4 卡
