flask开发中遇到jinja2.exceptions.UndefinedError: 'flask_

?flask开发中遇到jinja2.exceptions.UndefinedError: 'flask_moment._moment object' has no attribute 'formNow

这句话的意思是在这个网页的jinja2模板中有一个单词写错

{%?extends?"base.html"?%}
{%?import?"bootstrap/wtf.html"?as?wtf?%}
{%?block?title?%}Flasky{%?endblock?%}
{%?block?page_content?%}
<div?class="page-header">
????<h1>Hello,?{%?if?current_user.is_authenticated?%}
????????{{?current_user.username?}}
????????{%?else?%}
????????Stranger
????????{%?endif?%}
????!</h1>
????<!--如果该用户信息存在数据库-->
????{%?if??known?%}
????<p>非常高兴再次看见你</p>
????{%?else?%}
????<p>很高兴认识你</p>
????{%?endif?%}
</div>
<div>
????{%?if?current_user.can(Permission.WRITE_ARTICLES)?%}
????????{{?wtf.quick_form(form)?}}
????{%?endif?%}
</div>
<ul?class="posts">
????{%?for?post?in?posts?%}
????<li?class="post">
????????<div?class="post-thumbnail">
????????????<a?href="{{?url_for(".user",?username=post.author.username)?}}">
????????????????<img?class="img-rounded?profile-thumbnail"?src="{{?post.author.gravatar(size=40)?}}">
????????????</a>
????????????<div?class="post-data">{{?moment(post.timestamp).formNow()?}}</div>
????????????<div?class="post-author">
????????????????<a?href="{{?url_for('.user',?username=post.author.username)?}}">
????????????????????{{?post.author.username?}}
????????????????</a>
????????????</div>
????????????<div?class="post-body">{{?post.body?}}</div>
????????</div>
????</li>
????{%?endfor?%}
</ul>
{%?endblock?%}

根据提示迅速找到出错的一句代码:

<div?class="post-data">{{?moment(post.timestamp).formNow()?}}</div>

发现是fromNow() 拼写错误
