Haystack with Whoosh

本文介绍了Haystack with Whoosh-搜索结果不重定向的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我成功安装了whoosh，并与Haystack一起工作。事情工作正常，但我正面临着一个问题：在搜索关键字并打印出结果后，当我点击结果（标题）时，它不会将我重定向到我点击的关键字的页面，它只是静态的。我尝试添加一个get_absolute_url方法。但是它不起作用我缺少什么？

模型

class Meek user = models.ForeignKey（User） title = models.CharField（max_length = 250，unique = True） address = models.CharField（max_length = 200） city = models.CharField（max_length = 200） state = models.CharField（max_length = 200） main_view = models.ImageField（upload_to =photos，blank = True，null = True ） side_view = models.ImageField（upload_to =photos，blank = True，null = True） pub_date = models.DateTimeField（） def __unicode __（self） return self.title @ models.permalink def get_absolute_url（self）： return（'findme'，（），{'main_view'：self.main_view，'side_view'：self.side_view，'address'：self.address，'city'：self.city ，'state'：self.state}）

Urlconf

#url对象发布的位置。 （r'^ find / $'，findme）， #haystack url你可以在哪里搜索（r'^ search /'，include（'haystack.urls' ）），

视图：

def findme（request）： extra_data_context = {} ＃if这个字段什么都没做。 如果request.method ==POST： form = MeekForm（request.POST，request.FILES）如果form.is_valid（）： data = form.cleaned_data newmeeks = Meek（ user = request.user， pub_date = datetime.datetime.now（）， title = data ['title']， main_view = request.FILES ['main_view']， side_view = request.FILES ['side_view']， address = data ['address']， city = data ['city'] ， state = data ['state']） newmeeks.save（） extra_data_context.update（{'MeekForm'：form}） else： form = MeekForm（） extra_data_context.update（{'MeekForm'：form}） extra_data_ context.update（{'Meeks'：Meek.objects.filter（user = request.user）}） return render_to_response（'postme.html'，extra_data_context，context_instance = RequestContext（request））

解决方案

在 get_absolute_url URL被称为 findme ，你给它五个参数。在您的网址配置中，URL位于此处：

• 不会调用 findme （即，您需要具有 name =findme）和
• 它也不包含任何参数。 li>

例如，以下URL同时具有名称和命名参数（请参阅关于URL的文档了解更多信息）：

code>（r'^ articles /（？P< year> \d {4}）/ $'，'news.views.year_archive'，name =news_year_archive），

您需要使用参数 main_view ， side_view ，地址， city 和 state 所以Django可以正确地反转URL并提供模型的绝对URL。

I successfully installed whoosh and made it work with Haystack. Things are working fine but I'm facing one problem which is; after searching for a keyword and it print out the results, when I click on the result(title), It won't redirect me to the page of the keyword I clicked on, it's just static. I tried adding a get_absolute_url method. Yet it's not working. What I'm I missing?

Models

class Meek(models.Model): user=models.ForeignKey(User) title=models.CharField(max_length=250, unique=True) address=models.CharField(max_length=200) city=models.CharField(max_length=200) state=models.CharField(max_length=200) main_view=models.ImageField(upload_to="photos",blank=True, null=True) side_view=models.ImageField(upload_to="photos",blank=True, null=True) pub_date=models.DateTimeField() def __unicode__(self): return self.title @models.permalink def get_absolute_url(self): return ('findme', (), { 'main_view': self.main_view, 'side_view': self.side_view, 'address': self.address, 'city': self.city, 'state': self.state})

Search/search.html

{% 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= "{{ result.object.get_absolute_url }}" >{{ 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={{ query }}&amp;page= {{ page.previous_page_number }}">{% endif %}&laquo; Previous{% if page.has_previous %}</a> {% endif%} {% if page.has_next %}<a href="?q={{ query }}&amp;page={{ page.next_page_number }}">{% 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 %}

Urlconf

#url where the objects are posted. (r'^find/$', findme), #haystack url where you can search (r'^search/', include('haystack.urls')),

Views:

def findme(request): extra_data_context={} #if there's nothing in the field do nothing. if request.method=="POST": form=MeekForm(request.POST, request.FILES) if form.is_valid(): data=form.cleaned_data newmeeks=Meek( user=request.user, pub_date=datetime.datetime.now(), title=data['title'], main_view=request.FILES['main_view'], side_view=request.FILES['side_view'], address=data['address'], city=data['city'], state=data['state']) newmeeks.save() extra_data_context.update({'MeekForm':form}) else: form = MeekForm() extra_data_context.update({'MeekForm':form}) extra_data_context.update({'Meeks':Meek.objects.filter(user=request.user)}) return render_to_response('postme.html',extra_data_context,context_instance=RequestContext(request))

解决方案

In get_absolute_url your URL is called findme and you're giving it five parameters. In your URL configuration, the URL is there but:

• it is not called findme (i.e., you need to have name="findme"), and
• it also does not contain any parameters.

For example, the following URL has both a name and a named parameter (see documentation on URLs for more information):

(r'^articles/(?P<year>\d{4})/$', 'news.views.year_archive', name="news_year_archive"),

You need to create a similar URL with the parameters main_view, side_view, address, city and state so Django can properly reverse the URL and provide an absolute URL for the model.
