选择字段生成 [不是有效的选择] 错误时我尝试提交表单

Question

forms.py

class myForm(FlaskForm):

     ...

     time = SelectField('Hour', choices=[(8, "8AM"), (9,"9AM"), (10,"10AM"), (11,"11AM"), (12,"12PM"), (13,"1PM"), (14,"2PM"), (15,"3PM"), (16,"4PM"), (17,"5PM"), (18,"6PM")])

     ...

routes.py

form = RequestCalendarAppointment()

if form.validate_on_submit():

     print('Form validated')

形式.html

...

<p>

     {{ form.time.label() }}<br>

     {{ form.time() }}

     {% for error in form.time.errors %}

     <span style="color: red;">[{{ error }}]</span>

     {% endfor %}

</p>

我所有的字符串字段和整数字段都有效;但是，当我尝试提交选定字段时间的表单时，我的HTML页面中出现错误。我希望“8AM”显示在html页面（确实如此）中，并将8保存在表单.time.data中。[Not a valid choice]

Answer 1

对于“选定字段”选项，我使用字符串而不是整数
