flask 同一页面上的多个表单

Question

我的 Flask 应用程序出现问题，基本上我在同一个 html 页面中有两个表单，当我提交一个或另一个时，它会同时提交两个表单。有什么办法可以将它们分开，这样我就可以单独提交它们了吗？

@app.route('/smtp/', methods=['GET', 'POST'])
def smtp():
    form = UpdateSMTPForm()
    form2 = UpdateEmailAddress()
    query = Email.query.all()

    if  form.validate_on_submit():
        email = str(form.email.data)
        password = str(form.password.data)
        server = str(form.server.data)
        port = str(form.port.data)

        if tools.test_email(server, port, email, password):
            CONFIG['SMTP']['server'] = server
            CONFIG['SMTP']['port'] = port
            CONFIG['SMTP']['username'] = email
            CONFIG['SMTP']['password'] = password

            with open('config.json', 'w') as f:
                f.write(json.dumps(CONFIG))
                f.close()
        else:
            form.server.errors.append("Invalid account, be sure that you have less secure app access turned on or try with a gmail account")


    if form2.validate_on_submit():
        print('form2 email updated {}'.format(form2.email))
    else:
        print('cannot validate the second form')

    return render_template('smtp.html', config=CONFIG['SMTP'], query=query, form=form, form2=form2)

您可以通过提交输入来区分这些表单。只需将它们设置为不同的 id/name 并通过检查其 id/name 是否存在于 request.form.

中来检查表单提交是否源自此特定表单

第一种形式：

<input type="submit" id="form-submit" name="form-submit" value="Submit form">

第二个：

<input type="submit" id="form2-submit" name="form2-submit" value="Submit form2">

以及您认为的逻辑：

@app.route('/smtp/', methods=['GET', 'POST'])
def smtp():
    form = UpdateSMTPForm()
    form2 = UpdateEmailAddress()
    query = Email.query.all()

    if  "form-submit" in request.form and form.validate_on_submit():
        email = str(form.email.data)
        password = str(form.password.data)
        server = str(form.server.data)
        port = str(form.port.data)

        if tools.test_email(server, port, email, password):
            CONFIG['SMTP']['server'] = server
            CONFIG['SMTP']['port'] = port
            CONFIG['SMTP']['username'] = email
            CONFIG['SMTP']['password'] = password

            with open('config.json', 'w') as f:
                f.write(json.dumps(CONFIG))
                f.close()
        else:
            form.server.errors.append("Invalid account, be sure that you have less secure app access turned on or try with a gmail account")


    if "form2-submit" in request.form and form2.validate_on_submit():
        print('form2 email updated {}'.format(form2.email))
    else:
        print('cannot validate the second form')

    return render_template('smtp.html', config=CONFIG['SMTP'], query=query, form=form, form2=form2)
