Python 如何将Jinja2模板中的多个变量传递给Flask

在我的代码中，我试图将两个变量从Jinja2模板传递到flask。 到目前为止，我所做的就是：

<th><a href="{{ url_for('admin.edit', title=post.title ,url=prop.url) }}">{{ post.url }}    </a></th>

我从调试器中得到的错误是get（）正好接受3个非关键字参数（给定2个）

我使用的模板是：

{% extends "admin/base.html" %}
{% block content %}
  <table  class="condensed-table zebra-striped">
    <thead>
   <th>Title</th>
   <th>Url</th>
  <th>Date Added</th>
  <th>Actions</th>
</thead>
<tbody>

{% for post in posts %}
  <tr>


    <td>{{post.url}}</td>


    <th><a href="{{ url_for('admin.edit', title=post.title, url=post.url ) }}">{{ post.url }}</a></th>
    <td>{{ post.date_added}}</td>
    <!-- <td>{{ post.created_at.strftime('%Y-%m-%d') }}</td> -->
    <td><a href="{{ url_for("admin.edit", title=post.title , url=post.url ) }}" class="btn primary">Edit</a></td>
  </tr>
   {% endfor %}
{% endfor %}
</tbody>

{%extends“admin/base.html”%}
{%block content%}
标题
网址
添加日期
行动
{posts%%中的post为%s}
{{post.url}
{{post.date_added}}
{%endfor%}
{%endfor%}

可能的重复：您能否提供完整的回溯？是否使用基于类的视图？否则，函数签名中的

self

可能就是问题所在。您用于此视图的url模板是什么，以及您在浏览器中为此异常输入的url是什么？是的，我使用的是“基于”视图，如果我从href标记中取出url并从get方法中取出url，则我提供的代码可以使用
