在我的代码中，我试图将 Jinja2 模板中的两个变量传递给烧瓶。到目前为止，这就是我所做的：

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

在我的烧瓶视图中，它甚至在到达 get 方法之前就出错了：

 def get(self, title, url):
    print "geturl"

我从调试器得到的错误是 get() 正好需要 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>
