Question

我正在写博客，并向网站添加了add_article函数。

当我尝试添加文章时，在终端上我可以看到请求是POST且工作正常，但是我没有收到Flash消息或重定向到指定的url，并且文章未保存到MySQL数据库。

我尝试打印form.errors，但也没有显示任何内容。

from flask import Flask, render_template, flash, redirect, url_for, session, logging, request
from flask_mysqldb import MySQL
from wtforms import Form, StringField, TextAreaField, PasswordField, validators
from passlib.hash import sha256_crypt
from functools import wraps

class Article(Form):

   title = StringField("Title",validators=[validators.Length(min=5, max=100)])
   content = TextAreaField("Content", validators=[validators.Length(min=10)])

@app.route("/addarticle", methods = ["GET", "POST"])
def add_article():

   form = Article(request.form)
   if request.method == ["POST"] and form.validate():

       title = form.title.data
       content = form.content.data

       cursor = MySQL.connection.cursor
       inquiry = "INSERT INTO articles(title, author, content) VALUES(%s,%s,%s)"
       cursor.execute(inquiry,(title, session["username"], content))

       mysql.connection.commit()
       cursor.close()

       flash("Article added successfuly.","success")
       return redirect(url_for("dashboard"))

   return render_template("addarticle.html", form = form)

Django POST请求未保存在MySQL数据库上
