django 通用视图(generic view)获取 request

from django.views import generic
from blog.models import *
from ipware.ip import get_ip



class IndexView(generic.ListView):
    template_name = 'lw-index-noslider.html'  # 加载该html文件
    context_object_name = "articles"  # 是数据库搜索出来的结果存放的变量名字,用于模板循环显示
    paginate_by = 4  # 设置分页中每一页的记录数目
    model = Article  # 定义从哪份model中查询

    def get_queryset(self):    
        return Article.objects.filter(show_status=True).order_by('-time_created')

    def get_context_data(self, **kwargs):
        context = super(IndexView, self).get_context_data(**kwargs)
        context['cloudtags'] = Tag.objects.filter().order_by("-id")[:8]
        context['nodes'] = Node.objects.filter().order_by("-id")[:8]
        context['quotations'] = get_quotations(2)
        return context

    def dispatch(self, request, *args, **kwargs):
        # Try to dispatch to the right method; if a method doesn't exist,
        # defer to the error handler. Also defer to the error handler if the
        # request method isn't on the approved list.
        # 这里的 request 就是普通 view 里面 request

        print(get_ip(request))
        if request.method.lower() in self.http_method_names:
            handler = getattr(self, request.method.lower(), self.http_method_not_allowed)
        else:
            handler = self.http_method_not_allowed
        return handler(request, *args, **kwargs)
