django 数据库返回queryset实现封装为字典

默认情况下，Python DB API会返回不带字段的结果，这意味着你得到的是一个列表，而不是一个字典。花费一点性能代价之后，你可以返回一个字典形式的结果，像这样：

def dictfetchall(cursor):
"Returns all rows from a cursor as a dict"
desc = cursor.description
return [
 dict(zip([col[0] for col in desc], row))
 for row in cursor.fetchall()
]

demo：

from django.db import connection
if __name__ == '__main__':
 """db=db_operate()
 sql='select DISTINCT t1.HostName,t2.IpAddress,t2.RegName,t2.AppUser,t2.`Desc` from machineinfo as t1,asset_appregioninfo as t2 where t1.IpAddress=t2.IpAddress;'
 result=db.mysql_command(settings.conn, sql)
 dic=dict(result)
 print dic
 """
 cur=connection.cursor()
 cur.execute('select DISTINCT t1.HostName,t2.IpAddress,t2.RegName,t2.AppUser,t2.`Desc` from machineinfo as t1,asset_appregioninfo as t2 where t1.IpAddress=t2.IpAddress;')
 dic=dictfetchall(cur)
 print dic

这样在前台，就可以通过

{％for i in dic％}
{i.字段}

生成列表了

补充知识：[django] queryset系列化3种方式model_to_dict、serializers

我就废话不多说了，大家还是直接看代码吧！

# 序列化方式1:
from django.forms.models import model_to_dict
import json
data=[]
for obj in book_list:
 data.append(model_to_dict(obj))
print(data)
return HttpResponse("ok")

# 序列化方式2:
data=serializers.serialize("json",book_list)
return HttpResponse(data)

# 序列化方式3:
bs=BookSerializers(book_list,many=True)
return Response(bs.data)
