1、扩展auth_user

from django.contrib.auth.models import User,AbstractUser

class UserInfo(AbstractUser):

        tel = models.CharField(max_length=32)

setting配置

AUTH_USER_MODEL = 'app01.UserInfo'

1.根据str，拿字段对象，取中文

    val = self.model._meta.get_field(field).verbose_name

2.模型名称，app名称

    model_name = self.model._meta.model_name

    app_lable = self.model._meta.app_label

3.判断是否可调用

    if callable(field):

        val = field(self, header = True)

4.字符串找对象得属性，反射

    val = getattr(data, field)

5.返回标签

　　 from django.utils.safestring import mark_safe

    return mark_safe("<input id='choice' type='checkbox'>")

6.插入数组[]

    temp.append(ModelStark.checkbox)

    temp.extend(self.list_display)

7.反向解析，含正则

    _url = reverse("%s_%s_delete" % (app_label, model_name), args=(obj.pk,))

    _url = reverse("%s_%s_add" % (app_label, model_name))

8.复选框

    $('#choice').click(function () {

        if($(this).prop('checked')){

            $('.choice_item').prop('checked',true)

        }else{

            $('.choice_item').prop('checked',false)

        }

    })

1.判断用户是否配置，配置才显示search框, get查询

    search_fields = ['title', 'price']

    显示key_words{{ showlist.config.key_words }}

    {% if showlist.config.search_fields %}

        <form action="" class="pull-right">

            <input type="text" name="q" value="{{ showlist.config.key_words }}">
　　　　　　　　<button>submit</button>

        </form>

    {% endif %}

2.Q对象

    # 获取search得Q对象

    search_connection = self.get_search_condition(request)

    # print("connection:",search_connection)

    # connection: (or: ('title__contains', '3'), ('price__contains', '3'))

    # 筛选当前表得所有数据

    data_list = self.model.objects.all().filter(search_connection)

3.Q查询

    两种方式，一种可以放str,就是下面这种，一种放字段；

    def get_search_condition(self, request):

        key_words = request.GET.get('q', "")

        self.key_words = key_words

        # self.search_fields   ['title','price']

        from django.db.models import Q

        search_connection = Q()

        if key_words:

            search_connection.connector = "or"

            for search_field in self.search_fields:

                search_connection.children.append((search_field+"__contains", key_words))

        return search_connection

4.模糊查询

    (title__contains)(price__contains)

    search_connection.children.append((search_field+"__contains", key_words))
