How to pass multiple variables in Jinja2 template to Flask

Question

In my code im am trying to pass two variables from the Jinja2 template to flask. So far this is what i have done:

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

and in my flask view it errors before it even hits the get method:

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

The error i get from the debugger is get() takes exactly 3 non-keyword arguments (2 given)

TypeError: get() takes exactly 3 non-keyword arguments (2 given)

The template i am using is:

{% 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>

Are you using class based views? Otherwise, that `self` in your function signature is likely the problem. — Thomas Fenzl, Jun 29 '13 at 15:29
What url template you use for this view and what url you input in browser for this exception? — tbicr, Jun 29 '13 at 15:30
yes i am using the based view, the code i have provided works with if i take out the url from the href tag and url from the get method — Kimmy, Jun 29 '13 at 16:45
The url i input my browser is http://0.0.0.0:5000/admin/Title/?url=Url — Kimmy, Jun 29 '13 at 16:48
