推荐答案

您可以尝试

from django.db import connection
connection.queries

它将为您提供通过Django执行的所有查询的列表(包括.save()).要获取查询，您可以做到

it will give you list of all the queries that executed through Django (including .save()). To get your query you can do,

from django.db import connection, OperationalError
try:
    modelObj.save()
except OperationalError:
    print(connection.queries[-1])
