我有以下代码,我在查询我的peewee数据库.我在具有term.sets_term_id的行上的for循环中收到错误.这是错误TermsDoesNotExist：实例匹配查询不存在：如果我执行变量(term),则sets_terms_id是一个选项.为什么我会收到该错误以及如何解决？
def get_api_response(id):
response = {}
print("id is " + str(id))
try:
sets = models.Sets.select().where(models.Sets.user_id == id)
except models.DoesNotExist:
return json.loads({'error' : 'that set does not exist'})
else:
print("it was successful")
for term in sets:
print(term.sets_term_id)
这是我的套装和条款模型
