实现搜索功能

models.PrettyNum.objects.filter(id=12)       # 等于12
models.PrettyNum.objects.filter(id__gt=12)   # 大于12
models.PrettyNum.objects.filter(id__gte=12)  # 大于等于12
models.PrettyNum.objects.filter(id__lt=12)   # 小于12
models.PrettyNum.objects.filter(id__lte=12)  # 小于等于12

data_dict = {"id__lte":12}
models.PrettyNum.objects.filter(**data_dict)
```

```python
models.PrettyNum.objects.filter(mobile="999")               # 等于
models.PrettyNum.objects.filter(mobile__startswith="1999")  # 筛选出以1999开头
models.PrettyNum.objects.filter(mobile__endswith="999")     # 筛选出以999结尾
models.PrettyNum.objects.filter(mobile__contains="999")     # 筛选出包含999

data_dict = {"mobile__contains":"999"}
models.PrettyNum.objects.filter(**data_dict)

# 靓号管理
def pretty_list(request):
    '''靓号列表'''
    #搜索条件
    data_dict={}
    #q是属性name的值，""是默认值
    search_data=request.GET.get('q',"")
    if search_data:
        data_dict["mobile__contains"]=search_data
    #带条件查询
    queryset = models.PrettyNum.objects.filter(**data_dict).order_by("-level")

    return render(request, 'pretty_list.html', {"queryset": queryset,"search_data":search_data})
