(干草堆+飞快移动){{result.object.get_absolute_url}}无法正常工作 [英] (haystack + whoosh) {{ result.object.get_absolute_url }} is not working
问题描述
我正在django(1.7)网站中使用haystack(2.1.1)和whoosh。我很高兴,因为它正在工作,但并不完全。该应用显示正确的搜索,但是当我单击搜索结果时,它不会转到产品页面。看来我尚未配置某些使{{result.object.get_absolute_url}}无法正常工作的功能。我希望你们中的任何一个都可以帮助我(作为参考,我把所有代码都放进去了)
I am using haystack (2.1.1) and whoosh in my django (1.7) website. i am happy because it is working, but not completely. the app show the right searches but when i click in the results it doesn't go to the product page. it looks like i haven't configured something that make {{ result.object.get_absolute_url }} doesnt work properly. I hope any of you can help me (as reference i am putting all the code)
这是我的应用程序模型(产品/模型)
this is my app models (products/models)
from django.db import models
class Products(models.Model):
name = models.CharField(max_length=120)
description = models.TextField()
image1 = models.ImageField(upload_to='product_images', blank=True, null=True)
price = models.FloatField(default=0.00)
slug = models.CharField(max_length=50, blank=False, null=True)
pub_date = models.DateTimeField()
def __unicode__(self):
return str(self.name)
class Meta:
ordering =['-id']
verbose_name = ('Product')
verbose_name_plural = ('Products')
这是我的search_indexes.py,我在我的应用程序的同一文件夹(products / search_indexes.py)
this is my search_indexes.py, that i put in the same folder of my app (products/search_indexes.py)
import datetime
from haystack import indexes
from products.models import Products
class ProductsIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
name = indexes.CharField(model_attr='name')
description = indexes.CharField(model_attr='description')
pub_date = indexes.DateTimeField(model_attr='pub_date')
def get_model(self):
return Products
def index_queryset(self, using=None):
return self.get_model().objects.filter(pub_date__lte=datetime.datetime.now())
我在设置文件中进行了更改
I did the changes in the settings file
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE': 'haystack.backends.whoosh_backend.WhooshEngine',
'PATH': os.path.join(os.path.dirname(__file__), 'whoosh_index'),
},
}
在我的模板文件夹 templates / search / indexes / products / products_text.txt中创建文件
create the file in my template folder "templates/search/indexes/products/products_text.txt"
{{ object.name }}
{{ object.description }}
HTML和url与haystack网站中的相同(只需将result.object.title更改为result.object.name)。在网址中:(r'^ search /',include('haystack.urls'))和html(templates / search / search.html)
the HTML and urls are the same as in the website of haystack (just change the result.object.title for result.object.name). in URLS: (r'^search/', include('haystack.urls')) and html (templates/search/search.html)
{% extends 'base.html' %}
{% block content %}
<h2>Search</h2>
<form method="get" action=".">
<table>
{{ form.as_table }}
<tr>
<td> </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.name }}</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 }}&page={{ page.previous_page_number }}">{% endif %}« Previous{% if page.has_previous %}</a>{% endif %}
{% if page.has_next %}<a href="?q={{ query }}&page={{ page.next_page_number }}">{% endif %}Next »{% if page.has_next %}</a>{% endif %}
</div>
{% endif %}
{% else %}
{# Show some example queries to run, maybe query syntax, something else? #}
{% endif %}
</form>
{% endblock %}
我在搜索并显示它之前说过。但是我不知道为什么{{result.object.get_absolute_url}}无法正常工作,因此它显示了产品标题,但没有将它们链接到其页面。
as i said before it does the search and show it. but i don't know why the {{ result.object.get_absolute_url }} is not working, so it shows the product tittle but doesn't link them to their pages.
推荐答案
您只需要在模型类上显式定义一个 get_absolute_url
方法:
You just need to define a get_absolute_url
method explicitly on your model class:
class Products(models.Model):
...
def get_absolute_url(self):
return "/products/%s/" % self.slug
使用 reverse甚至会更好
在此方法中,具体取决于您的urlconf。 此处。
It would be even better to use reverse
within this method, which will depend on your urlconf. More details here.
