我使用原始查询从数据库中直接获取数据而不是ORM.我想按照 order_data 在 order_data 中获取 order_detail_dataorder_id，根据上述详细信息.
我正在尝试解决这个问题，但我没有得到任何可以解决这个问题的可能答案.如果有人能帮我解决我正在寻找的问题，那就太好了.非常感谢您！

i am direct fetching data using raw query from databases instead of ORM. i want to get order_detail_data inside order_data as per order_id, per above details.
i am trying to solve this problem, but i didn't get any possible answer which could solve this problem. It would be great if anyone could help me out for what i am looking for. Advance thank you so much!.
After 16 hours struggle i found solution:
class Order_ListAPIView(APIView):
def get(self,request,format=None):
totalData=[]
if request.method == 'GET':
cur,conn = connection()
order_query = ''' SELECT * FROM orders'''
order_detail_query = ''' SELECT * FROM order_details LEFT JOIN orders ON order_details.order_detail_id = orders.order_id '''
with conn.cursor(MySQLdb.cursors.DictCursor) as cursor:
cursor.execute(order_detail_query)
order_detail_result = cursor.fetchall()
order_detail_data = list(order_detail_result)
# print(order_detail_data)
cursor.execute(order_query)
order_result = cursor.fetchall()
order_data = list(order_result)
dic = {}
def merge_order_data_and_detail(order_data, order_detail_data):
for d in order_detail_data:
if d['order_id'] not in dic:
dic[d['order_id']] = []
dic[d['order_id']].append(d)
for o in order_data:
if o['order_id'] in dic:
o['order_detail_data'] = dic[o['order_id']]
merge_order_data_and_detail(order_data, order_detail_data)
totalData.append({"order_data":order_data, })
return Response({"totalData":totalData,},status=status.HTTP_200_OK)
else:
return Response(status=status.HTTP_400_BAD_REQUEST)
