Django + haystack + solr:配置让django站点用solr来搜索

环境搭建所需软件包请参考：CentOS 搭建 solr环境  http://www.linuxidc.com/Linux/2011-05/36394.htm

1、首先当然得创建新的项目：django-admin startproject testsolr

                                                manage.py startapp note

2、修改settings文件，添加haystack相关配置及db配置

haystack相关： HAYSTACK_SITECONF = ‘note.search_sites’

                          HAYSTACK_SEARCH_ENGINE = ‘solr’

                          HAYSTACK_SOLR_URL = ‘http://127.0.0.1:8080/solr/’

DATABASES 配置本文省略，请根据自己的情况进行相应配置；

INSTACLLED_APPS 里面需添加haystack和note

至此，django部分需要配置的就这些。

说明：note app中需要新建编辑search_indexes.py search_sites.py，编辑完成后执行manage.py build_solr_schema,

将输出的信息保存至schema.xml并覆盖至solr配置文件所在文件夹下的schema.xml，然后执行manage.py rebuild_index.

3、urls配置，url(r’^search/’, include(‘haystack.urls’))

这个默认会调用haystack的模板，默认在templates下缺少search/search.html，故需要创建：代码如下

{% block content %}
    <h2>Search</h2>

    <form method=”get” action=”.”>
        <table>
            {{ form.as_table }}
            <tr>
                <td>&nbsp;</td>
                <td>
                    <input type=”submit” value=”Search”>
                </td>
            </tr>
        </table>

        {% if query %}
            <h3>Results</h3>

            {% for result in page.object_list %}
                <p>
                    <a href=”{{%20result.object.get_absolute_url%20}}”>{{ result.object.title }}</a>
                </p>
            {% empty %}
                <p>No results found.</p>
            {% endfor %}

            {% if page.has_previous or page.has_next %}
                <div>
                    {% if page.has_previous %}<a href=”?q={{%20query%20}}&amp;page={{%20page.previous_page_number%20}}”>{% endif %}&laquo; Previous{% if page.has_previous %}</a>{% endif %}
                    |
                    {% if page.has_next %}<a href=”?q={{%20query%20}}&amp;page={{%20page.next_page_number%20}}”>{% endif %}Next &raquo;{% if page.has_next %}</a>{% endif %}
                </div>
            {% endif %}
        {% else %}
            {# Show some example queries to run, maybe query syntax, something else? #}
        {% endif %}
    </form>
{% endblock %}
