Python 如何使用django添加meta关键字
我使用下面的代码添加元关键字- in view.pyPython 如何使用django添加meta关键字,python,django,keyword,meta-tags,Python,Django,Keyword,Meta Tags,我使用下面的代码添加元关键字- in view.py @template_render("mysite/category.html") def category(request, slug): slug = slug.lower() product_type = local_settings.CATEGORY_NAME_TO_ID.get(slug, False) if not product_type: raise Http404 product
@template_render("mysite/category.html")
def category(request, slug):
slug = slug.lower()
product_type = local_settings.CATEGORY_NAME_TO_ID.get(slug, False)
if not product_type:
raise Http404
products = models.Product.objects.active().filter(product_type = product_type).all()
return { 'products' : products, 'slug' : slug, 'key':'wholesale ipad, ipad with retina display, ipad mini, ipad 3, ipad 2',}
{% extends "base.html"%}
{%load appletrade_tags%}
{% block key %}siteTrade - {{key}}{% endblock %}
{%block title%}site Trade - {{slug}}{%endblock%}
{% extends "base.html"%}
{% block key %}{%if page.key%}{{page.key}}{%else%}{{block.super}}{%endif%}{% endblock %}
{% block desc %}{%if page.desc%}{{page.desc}}{%else%}{{block.super}}{%endif%}{% endblock %}
{%block title%}{%if page.title%}{{page.title}}{%else%}{{block.super}}{%endif%}{%endblock%}

您需要使用render或render_to_响应将上下文传递给模板。slug对象是否出现在页面上
from django.shortcuts import render_to_response
def category(request, slug):
slug = slug.lower()
product_type = local_settings.CATEGORY_NAME_TO_ID.get(slug, False)
if not product_type:
raise Http404
products = models.Product.objects.active().filter(product_type = product_type)
context = {
'slug': slug,
'products': products,
'key': 'wholesale ipad, ipad with retina display, ipad mini, ipad 3, ipad 2',
}
return render_to_response('appletrade/category.html', context, context_instance=RequestContext(request))

这里有一种方法可以为django站点自动化关键字。无论如何，我不喜欢手工输入东西 这里有一个函数，可以读取模板文件并计算主要单词，然后返回页面中使用的单词列表

我意识到这是可以改进和优化的。我不在乎速度。因此，欢迎输入。这里有一种方法可以为django站点自动化关键字。无论如何，我不喜欢手工输入东西 这里有一个函数，可以读取模板文件并计算主要单词，然后返回页面中使用的单词列表

我意识到这是可以改进和优化的。我不在乎速度。因此，欢迎输入。谢谢。我是python新手。请突出显示我必须在代码中对其进行更改的位置好吗？已尝试，但出现错误“view appletrade.views.category未返回HttpResponse对象”。@HelloPython是否导入了render\u to\u响应？应该还有更详细的追踪。他忘了更改他的返回声明，他还在返回那份声明。好的，我能理解。谢谢：）谢谢。我是python新手。请突出显示我必须在代码中对其进行更改的位置好吗？已尝试，但出现错误“view appletrade.views.category未返回HttpResponse对象”。@HelloPython是否导入了render\u to\u响应？应该还有更详细的追踪。他忘了更改他的返回声明，他还在返回那份声明。好的，我能理解。谢谢：）真是太棒了，我正在寻找一种动态的方式来生成我的关键字，这个想法似乎非常完美，我也将使用它来从我的模型生成关键字！真是太棒了，我正在寻找一种动态的方式来生成我的关键字，这个想法似乎非常完美，我也将使用它来从我的模型生成关键字！
