在django模板中重定向用户

Question

我有一个django网站,根据您的用户类型而溢出,我需要重定向无权查看网站某些方面的用户,

在我的模板中,我有

{% if user.get_profile.is_store %}
    <!--DO SOME LOGIC-->
{%endif%}

我如何将所述商店重定向回网站索引？

==== ====编辑

def downloads(request):
    """
    Downloads page, a user facing page for the trade members to downloads POS etc
    """
    if not authenticated_user(request):
        return HttpResponseRedirect("/professional/")

    if request.user.get_profile().is_store():
        return HttpResponseRedirect("/")

    user = request.user
    account = user.get_profile()

    downloads_list = TradeDownloads.objects.filter(online=1)[:6]
    downloads_list[0].get_thumbnail()
    data = {}
    data['download_list'] = downloads_list

    return render_to_response('downloads.html', data, RequestContext(request))

Answer 1

我想,你想在不在模板中的视图中这样做.所以,像:

from django.http import HttpResponseRedirect

def myview(request):
    if request.user.get_profile().is_store():
        return HttpResponseRedirect("/path/")

    # return regular view otherwise

@decorator如果你发现自己需要做很多事情,你也可以使用a 作为视图.

Answer 2

使用HTML的原始重定向.

{% if user.get_profile.is_store %}
    <meta http-equiv="REFRESH" content="0;url=http://redirect-url">
{% endif %}

或者提供重定向url作为上下文变量

{% if user.get_profile.is_store %}
    <meta http-equiv="REFRESH" content="0;url={{ user.get_profile.store_url }}">
{% endif %}

如果内存服务正确,这必须在"head"标签内,但现代浏览器更宽容,Firefox 4允许它在"body"标签内并且工作正常.

Answer 3

你真的不想在模板中重定向,正如所有其他答案中所说的那样.

但是如果在视图中重定向是没有选择的(为什么有),你可以这样做:

{% if user.get_profile.is_store %}
    {% include '/path/to/template' %}
{% else %}
    {% include '/path/to/another_template' %}
{% endif %}

Answer 4

当然有时我们有从django官方代码导入的视图，或者其他不依赖于我们的视图。我们无法在这些视图中放置重定向，因此唯一的方法是通过这些（不可触及的）视图正在使用的模板。
