python - 记录 Django Haystack 搜索关键字

Question

我的 url.py 中有以下内容:

from haystack.forms import HighlightedModelSearchForm
from haystack.query import SearchQuerySet
from haystack.views import SearchView
from articles.models import Article

article_sqs = SearchQuerySet().models(Article)

urlpatterns = patterns('',
    ...
    url(r'^article/search/$', SearchView(
        template='articles/search/results.html',
        searchqueryset=article_sqs,
        results_per_page=10,
        form_class=HighlightedModelSearchForm
    ), name='haystack_search'),
...

它工作正常，但我需要捕获搜索关键字以记录它。

我怎样才能捕捉到它？

我们将不胜感激。

我想做类似的事情，所以我创建了一个名为 search

的应用

search/models.py

from django.db import models
from django.contrib.auth.models import User
from django.utils.translation import ugettext as _

class SearchTerm(models.Model):
    query = models.CharField(
        verbose_name = _(u'Search Term'),
        max_length = 255,
        default = None
    )

class SearchQuery(models.Model):
    term = models.ForeignKey(
        SearchTerm
    )
    user = models.ForeignKey(
        User,
        blank = True, 
        null = True,
    )
    when = models.DateTimeField(
        verbose_name = _(u'Date Searched'),
    )

search/urls.py

from django.conf.urls.defaults import *

urlpatterns = patterns('',
    url(r'^search/', 'search.views.search', name="search"),
)

然后当然在我的项目 url 中添加了以下规则:

url(r'^', include('search.urls')),

search/views.py

from django.http import HttpResponse
from django.shortcuts import get_object_or_404, render, redirect
from haystack.forms import ModelSearchForm, SearchForm
from haystack.views import SearchView
from search.models import SearchQuery, SearchTerm
import datetime

def search(request):
    if 'page' not in request.GET :
        try :
            st, created = SearchTerm.objects.get_or_create(query=request.GET['q'])
            sq = SearchQuery()
            sq.term = st
            sq.user = request.user
            sq.when = datetime.datetime.now()
            sq.save()
        except :
            pass

    view = SearchView()
    return view(request)

if 'page' not in request.GET这样只在搜索结果的第一页，保存一个SearchQuery

每个 SearchQuery 在数据库中都是唯一的。

SearchTerm 的每个 SearchQuery 都记录有附加信息，例如 user (可为空)和 when该词已被搜索。

view = SearchView()和 return view(request)让它在记录 SearchQuery 之后，为该请求调用默认的 haystack View 。
