# 1.查询所有的文章，完成文章的展示列表页 #

## （1）查询所有文章(views.py) ##

def showType(request):
        #types = Type.objects.all() #查询所有的数据
        #types = Type.objects.filter(label="小说",id = 3) #安装条件查询
        #types = Type.objects.filter(label="动画片").first() #安装条件查询，返回第一条，没有返回None
        #types = Type.objects.get(id = 18) #直接获取单条数据，没有报错,get查询的条件必须唯一，一般用id
        #通常排序安装时间排序
        #types = Type.objects.order_by("id") #排序 相当于all
        #types = Type.objects.order_by("-id") #排倒序
        #types = Type.objects.filter(label="小说").order_by("-id")
        types = Type.objects.filter()[:3].order_by() #限制条数
    
        return render_to_response("showType.html",locals())

## （2）将数据返回前端 ##

# 3.项目监听本机所有ip #

## （1）修改pycharm配置 ##

因为http协议默认端口是80,所以访问浏览器就不用写端口了，直接写ip即可

## （2）修改settings.py配置 ##

可以写自己的ip地址或者是    \["\*"\]
