烧瓶 SQLite 查询 [关闭]

Question

这不起作用。你怎样才能让它发挥作用？

        g.db.execute('update address set firstname=?,surname=?,email=?,mobile=? where contact_id = ?',\
                    [request.form['firstname'], request.form['surname'],\
                    request.form['email'], request.form['mobile'],[contact_id]])

完整方法：

@app.route('/edit/<int:contact_id>',methods=['GET','POST'])
def contact_edit(contact_id):
    contact_id = str(contact_id)
    if request.method == 'POST':

        g.db.execute('update address set firstname=?,surname=?,email=?,mobile=? where contact_id = ?',\
                    [request.form['firstname'], request.form['surname'],\
                    request.form['email'], request.form['mobile'],[contact_id]])
        g.db.commit()
        flash('The contact was successfully edited')
        return redirect(url_for('contact_detail'))
    elif request.method != 'POST':
        cur = g.db.execute('select contact_id, surname, firstname, email, mobile\
                       from address where contact_id = ?', [contact_id])
        select = cur.fetchall()
        return render_template('editcontact.html', select=select)

Answer 1

尝试删除contact_id 周围的括号，如下所示：

g.db.execute('update address set firstname=?,surname=?,email=?,mobile=? where contact_id = ?',\
                (request.form['firstname'], request.form['surname'],\
                request.form['email'], request.form['mobile'],contact_id))

希望这会有所帮助！
