我正在使用 Django Rest Framework 在现有数据库上执行 get() post() 。在模型中，我没有定义任何主键或外键关系，因为这些约束是在数据库级别处理的。当我有 debug = True在 settings.py 文件中，会显示带有回溯的数据库级错误。但是，当 debug = False 时，我希望在响应中显示错误。
例如:错误信息:
IntegrityError at /dqf_api/ReceiptLog/
(1062, "Duplicate entry 'ede pivot-dummy-ede_case_76-ede pivot command 76' for key 'PRIMARY'")
当 debug = True 时，会显示。当 debug = False 时，如何捕获并显示此错误？

网址.py
router = routers.DefaultRouter()
router.register(r'test_case_command_runs', views.TestCaseCommandRunViewSet)

urlpatterns = [
url(r'^dqf_api/', include(router.urls)),
url(r'^dqf_api/ReceiptLog/', views.ReceiptLogView.ReceiptLogViewSet.as_view(), name='ReceiptLog')]
编辑:代码修复
将此添加到 serializers.py
def create(self, validated_data):
try:
return super().create(validated_data)
except IntegrityError as e:
error_msg = "IntegrityError occurred while creating entry in test_case_command_run_result model. Detailed Error: %s" %e
raise serializers.ValidationError(error_msg)
最佳答案
也许尝试这样的事情:
if serializer.is_valid():
serializer.save()
return Response("success")
else:
return Response(serialzier.errors)
