使用 Flask 将表格结果列出到 HTML

Question

我正在努力将我的 SELECT all 语句结果传递给我的视图。我正在使用烧瓶和 MySQLdb。将我的所有结果从我的表格显示到我的 HTML 页面的正确语法是什么？我很想通过一个列表，但无法弄清楚它的语法。

HTML 调用 {{ session.qid }} 只是为了测试，没有任何显示。

这是我目前的python代码：

@app.route('/view_answered/', methods=['GET','POST'])
def view_answered():
    error = ''
    try:
        if request.method == 'POST':
            c, conn = connection()
            clientcid = session['clientcid']

            cursor.execute("SELECT * FROM tickets WHERE cid = 1 AND solved = 0")
            results = cursor.fetchall()
            x = 0
            qid = []
            difficulty = []
            time_stamp = []
            title = []
            body = []

            for row in results:
                qid[x] = row[0]
                difficulty[x] = row[3]
                time_stamp[x] = row[4]
                title[x] = row[6]
                body[x] = row[7]

                x = x + 1

            conn.commit()
            c.close()
            conn.close()
            gc.collect()
            session['qid'] = qid
            session['difficulty'] = difficulty
            session['time_stamp'] = time_stamp
            session['title'] = title
            session['body'] = body
            return redirect(url_for('view_answered'))

        else:
            error = "Something is aloof."

        return render_template("view_answered.html")

    except Exception as e:
        return(str(e))

用这段代码解决了，也干净多了！

@app.route('/view_answered/', methods=['GET','POST'])
def view_answered():
    error = ''
    try:
        result = ''
        c, conn = connection()
        clientcid = session['clientcid']
        c.execute("SELECT * FROM tickets WHERE cid = (%s) AND solved = 1", (clientcid,))
        result = c.fetchall()
        conn.commit()
        c.close()
        conn.close()
        return render_template("view_unanswered.html", result = result)

    except Exception as e:
        return(str(e))

VIEW（r[0]、r[2]等，对应SQL表中的列位置）

{% for r in result %}
        <li>Question ID: {{ r[0] }}</li>
        <li>Difficulty: {{ r[3] }}</li>
        <li>Time Submitted: {{ r[4] }}</li>
        <li>Title: {{ r[6] }}</li>
        <li>Body: {{ r[7] }}</li>
        <li>Answer: {{ r[8] }}</li>
        <li>By: {{ r[3] }}</li>
        <br><br>
{% endfor %}
