默認(rèn)情況下，Python DB API會(huì)返回不帶字段的結(jié)果，這意味著你得到的是一個(gè)列表，而不是一個(gè)字典?；ㄙM(fèi)一點(diǎn)性能代價(jià)之后，你可以返回一個(gè)字典形式的結(jié)果，像這樣：

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 connectionif __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

這樣在前臺(tái)，就可以通過(guò)

{%for i in dic%}{i.字段}

生成列表了

補(bǔ)充知識(shí)：[django] queryset系列化3種方式model_to_dict、serializers

我就廢話不多說(shuō)了，大家還是直接看代碼吧！

# 序列化方式1:from django.forms.models import model_to_dictimport jsondata=[]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)

以上這篇django 數(shù)據(jù)庫(kù)返回queryset實(shí)現(xiàn)封裝為字典就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
