这个是请求数据的过滤
admin_class.model.objects.filter (**filter_conditions) 相当于
>>> m={"source":0}
>>> models.Customer.objects.filter(**m)
<QuerySet [<Customer: 5676567@qq.com>]> 或者

如果 dict 里面没有数据，会筛选所有的数据如下：
>>> m={}
>>> models.Customer.objects.filter(**m)
<QuerySet [<Customer: 5676567@qq.com>, <Customer: 25064568@qq.com>, <Customer: 787874859@qq.com>, <Customer: 2165
64732@qqcom>]>

def table_filter(request,admin_class):
    """进行条件过滤并返回过滤后的数据"""

    filter_conditions = {}
    for k,v in request.GET.items():
        if v:
            filter_conditions[k]=v
    print("filter_conditions:",filter_conditions)

    #admin_class = king_admin.enabled_admins[crm][userprofile]

        query_sets = paginator.page(page)

查找类里面字段的属性信息
filed_obj = admin_class.model._meta.get_field (condtion) 相当于 

>>> m = models.Customer._meta.get_field("source")
>>> m
<filed_obj.choices.db.models.fields.SmallIntegerField: source>

类属性信息里面是否有 choices :filed_obj.choices 相当于：

>>> m.choices
((0, '' 转介绍 ''), (1, ''QQ 群 ''), (2, '' 官网 ''), (3, '' 百度推广 ''),

type(filed_obj).__name__查找属性的类型 相当于：

>>> type(m).__name__

''ForeignKey''

如果是外键的时候的用 get_choices 取值如

filed_obj.get_choices ()[1:]: 相当于
>>> m.get_choices()
[('''', ''---------''), (1, ''python'')]
前面 list [0] 是上面的标题，所以的从 list [1:] 开始切割
