Django Transaction何时打开连接？ @ transaction.commit_manually @ transaction.atomic

Question

我想知道dbConnection何时打开

考试 遵循逻辑 是否等待数据库连接到external_api_call

还是不？

@transaction.commit_manually
def do_something():
    # 1. now db connection open?    

    # api_call
    response= requests.get(~~~~)

    # 2. or db connection opened here?
    aa= User.objects.get(id=1)
