Django从Context_Processor函数中访问会话变量

Question

我在视图中设置了一个会话变量，如下所示：

def festival_theme(request, year, month, day, slug):
    festival = Project.objects.get(category__name=__('festival'), slug=slug)

    request.session['_active_festival_id'] = festival.id

    return render(request, 'web/festival/theme.html', {'festival':festival,})

然后在我的上下文处理器函数中，我想要获取这个会话变量的值。我如何才能做到这一点？

我试过了：

#context_processors.py
def festivals(request):
    s = SessionStore()
    activeFestivalId = s['_active_festival_id']
    allFestivals = Project.objects.filter(category__name='festival').order_by('-date')
    return {'allFestivals':allFestivals}

Answer 1

您应该能够通过在上下文处理器中使用request.session来访问会话。

#context_processors.py
def festivals(request):
    activeFestivalId = request.session.get('_active_festival_id', None)
    allFestivals = Project.objects.filter(
        category__name='festival').order_by('-date')
    return {'allFestivals': allFestivals}
