Ich habe Probleme mit get_absolute_url in einer Vorlage. Es scheint gut zu funktionieren, wenn ich nur eines meiner Shop-Objekte übergebe und sage {{ store.get_absolute_url }}
, aber wenn ich ein Wörterbuch von Geschäften durchlaufen muss und dann die get_absolute_url
Funktion verwenden, gibt es nichts zurück. Genau das, was ich tue, ist unten:Kann Djangos get_absolute_url nicht im Wörterbuch der Wörterbücher verwendet werden?
class Store(EthicalObject):
type = "Store"
name = models.CharField(max_length=50)
company = models.ForeignKey(Company, verbose_name="Company", null=True, blank=True)
location = models.OneToOneField(Location, verbose_name="Location", null=True, blank=True)
products = models.ManyToManyField('Product', related_name="%(class)s_related", db_table=u'ethicsdb_products_to_stores', blank=True)
companies = models.ManyToManyField('Company', related_name="%(class)s_related", db_table=u'ethicsdb_companies_to_stores', blank=True)
def get_absolute_url(self):
return ('store_details', [str(self.id)])
get_absolute_url = models.permalink(get_absolute_url)
Dies funktioniert:
views.py:
def fetch_sidebar_data(shop_object):
sidebar_modules = {}
if shop_object.content_type.name == 'company':
sidebar_modules['related_stores'] = shop_object.stores.all()
sidebar_modules['related_products'] = shop_object.products.all()
if shop_object.content_type.name == 'store':
sidebar_modules['related_companies'] = shop_object.companies.all()
sidebar_modules['related_products'] = shop_object.products.all()
if shop_object.content_type.name == 'product':
sidebar_modules['related_stores'] = shop_object.stores.all()
sidebar_modules['related_companies'] = shop_object.companies.all()
sidebar_modules['tags'] = shop_object.tags
return sidebar_modules['related_stores'][1]
def company_details(request, company_id):
company = get_object_or_404(Company, id=company_id)
sidebar_modules = fetch_sidebar_data(company)
return render_to_response('company/details.html', {'company': company, 'sidebar_modules': sidebar_modules}, context_instance=RequestContext(request))
template:
{% extends "base-onecol.html" %}
{% block page_div_extra_attr %}class="twocol"{% endblock %}
{% block sidebar_content %}
<div id="sidebar-right">
<h1>{{ sidebar_modules.name }}{{sidebar_modules.get_absolute_url }}</h1>
</div>
{% endblock %}
Das funktioniert nicht:
views.py:
def fetch_sidebar_data(shop_object):
sidebar_modules = {}
if shop_object.content_type.name == 'company':
sidebar_modules['related_stores'] = shop_object.stores.all()
sidebar_modules['related_products'] = shop_object.products.all()
if shop_object.content_type.name == 'store':
sidebar_modules['related_companies'] = shop_object.companies.all()
sidebar_modules['related_products'] = shop_object.products.all()
if shop_object.content_type.name == 'product':
sidebar_modules['related_stores'] = shop_object.stores.all()
sidebar_modules['related_companies'] = shop_object.companies.all()
sidebar_modules['tags'] = shop_object.tags
return sidebar_modules
template:
{% extends "base-onecol.html" %}
{% block page_div_extra_attr %}class="twocol"{% endblock %}
{% block sidebar_content %}
<div id="sidebar-right">
{% for module_name,module in sidebar_modules.items %}
{% ifequal module_name "related_stores" %}
<h3>Sold Here</h3>
{% for related_store in module.values %}
<a href="{{ related_store.get_absolute_url }}">{{ related_store.name }}</a><br/>
{% endfor %}
{% endifequal %}
{% ifequal module_name "related_products" %}
<h3>Buy Local</h3>
{{ module }}<br/>
{% endifequal %}
{% ifequal module_name "related_companies" %}
<h3>
{{ module }}<br/>
{% endifequal %}
{% ifequal module_name "tags" %}
{{ module }}<br/>
{% endifequal %}
{% endfor %}
</div>
{% endblock %}
Im zweiten, bekomme ich einfach keine Rückkehr aus get_absolute_url
. Ich weiß, dass es an anderen Orten funktioniert, wenn ich es drucke. Ist das ein Django-Fehler, die Unfähigkeit, get_absolute_url
in einem Wörterbuch von Wörterbüchern zu verwenden?
