python-3.x之为什么我提交表单的尝试返回“无效的日期时间值”

我创建了一个允许用户选择所需日期和时间的表单，但是在提交表单时却收到此错误消息

Not a valid datetime value 

我尝试包括所需的格式或标准的日期时间格式，但是得到了相同的结果

#Form.py 
class AddPostForm(FlaskForm): 
    post_title = StringField('Share Title', validators=[DataRequired()]) 
    description = StringField('Description', validators=[DataRequired()]) 
    share_date = DateTimeField('Share Date', validators=[DataRequired()]) 
 
 
#views.py 
 
@posts_blueprint.route('/add', methods=['GET', 'POST']) 
@login_required 
def add_post(): 
    form = AddPostForm() 
    if request.method == 'POST': 
        if form.validate_on_submit(): 
            new_post = Post(form.post_title.data, form.description.data,  
                            current_user.id, form.share_date) 
 
 
            db.session.add(new_post) 
            db.session.commit() 
            flash('New shared Item, {}added!'.format(new_post.post_title),  
                  'success') 
            return redirect(url_for('posts.user_posts')) 
       else: 
           flash_errors(form) 
           flash('ERROR! Recipe was not added.', 'error') 
 
   return render_template('add_post.html', title='Add Item', form=form)

用户应该能够输入所需的日期和时间并成功提交表格

请您参考如下方法:

您的数据库期望与表单发送的似乎之间存在冲突。
尝试查看模型中使用的日期格式，并尝试将表单数据打印到控制台以查看其提供的功能。
也可以尝试查看wtforms的文档，以查看它使用的日期类型，并将其与数据库模型中的date字段匹配。
