所以我一直在考虑为我的对象添加评级功能，并决定使用Agon-ratings https://github.com/eldarion/agon-ratings
i have followed their usage documentation <http://agon-ratings.readthedocs.org/en/latest/usage.html>
did this with my template,
{% extends "base.html" %}
{% load url from future %}
{% block title %}Don't you jus love easy food{% endblock %}
{% block content %}
{% load agon_ratings_tags %}
<br/>
<br/>
<div>
{% if found_entries %}
<p>You searched for "{{ query_string }}".</p>
{% for restaurant in found_entries %}
<div>
<div>
<table>
<tr>
<td>dxtcfyguvhyju</td>
<td><a href="{% url 'f4l_menu' restaurant.id %}">{{ restaurant.restaurant_name }}</td></a>
</tr>
<tr>
<td>Location</td>
<td>{{restaurant.address}}</td>
</tr>
</table>
{% endfor %}
{% overall_rating obj as the_overall_rating %}
<div class="overall_rating">{{ the_overall_rating }}</div>
<div id= "user_rating"></div>
{% endif %}
{% if query_string and not found_entries %}
<p>No results found.</p>
{% else %}
<p>Type a search query into the box above, and press "Submit" to search.</p>
{% endif %}
</div>
</div>
<div style="clear: both;"></div>
</div>
</div>
{% user_rating_js request.user obj %}
{% endblock %}
当我加载页面时，获取'str' object has no attribute '_meta'
我显然不明白我哪里出错了。顺便说一下，我是django开发者开发我的第一个django应用程序
追溯，

答案 0 :(得分：3)
obj似乎是一个字符串值。而不是模型实例。请验证obj变量的值。
编辑：
usage documentation中给出的解释是针对详细视图（具有或多或少的主要对象）。
如果您愿意在found_entries中显示每家餐厅的评分，则可能需要进行一些更改。 （如果没有请提及）
课程overall_rating在this line中已经过硬编码。为了能够在搜索结果中对每个餐馆进行评级，您必须进行更改。
答案 1 :(得分：1)
只需将您的2个模板标记更改为：
{% overall_rating yourappmodel as the_overall_rating %}和{% user_rating_js request.user yourappmodel %}
