    总结:

    客户信息展示
    		1. 母版和继承
    			{% extends 'layout'%}
    			{% load static%}
    			{% static '文件路径' %}
    			
    			block css js content
    			
    		2. 内容显示
    		一	普通字段 	{{ customer.qq }}
    				choices字段  {{ customer.get_class_type_display }}
    			
    		二	多对多    
    			自定义方法,返回字符串 		  
    				def show_classes(self):
    					return ' | '.join([str(i) for i in self.class_list.all()])
    						
    		三	显示状态 
    				form django.utils.safestring import mark_safe
    				mark_safe

     总结:

    	1. 增加客户
    	2. 编辑客户
    		form_obj = CustomerForm(instance=obj)
    		form_obj带着原有的数据,根据数据生成input的值
    		
    		form_obj = CustomerForm(request.POST,instance=obj)
    		将提交的数据和要修改的实例交给form对象
    		form_obj.save()  对要修改的实例进行修改
    	3. 公户变私户
    		CBV
    			self.request
    		
    		反射
    		orm操作:
    			models.Customer.objects.filter(id__in=ids).update(consultant=self.request.user)
    			self.request.user.customers.add(*models.Customer.objects.filter(id__in=ids))
    	4. 私户变公户	
    		orm操作:
    			models.Customer.objects.filter(id__in=ids).update(consultant=None)
    			self.request.user.customers.remove(*models.Customer.objects.filter(id__in=ids))
    		
    	5. 模糊查询
    	
    		all_customer = models.Customer.objects.filter(Q(qq__contains=query) | Q(name__contains=query),
                                                              consultant__isnull=True)
    		all_customer = models.Customer.objects.filter(Q(('qq__contains',query)) | Q(('name__contains',query)),
                                                              consultant__isnull=True)
    														  
    		def get_search_contion(self,query_list):
            
    			query = self.request.GET.get('query', '')
    			
    			q = Q()
    			q.connector = 'OR'
    			for i in query_list:
    				q.children.append(Q(('{}__contains'.format(i), query)))
            
            return q
    	
    	
    	6. 保留搜索条件
    		from django.http import QueryDict
    		
    		print('query',request.GET)  #  <QueryDict: {'query': ['alex']}>
    		
    		print(request.GET.urlencode()) query=alex
