python - GNU Health - 时区错误

Question

经过几天的搜索并尝试使用 pytz 和其他工具，我无法找到解决方案。

当用户在 GNU Health 中创建 Medication 打印输出列表时，会出现错误:

====== ERROR=======================

return datetime.astimezone((dt.replace(tzinfo=None))
TypeError: astimezone() argument 1 must be datetime.tzinfo, not None

我不知道如何解决这个问题

Answer 1

这是 the current code for get_print_date() :

def get_print_date():
    Company = Pool().get('company.company')

    timezone = None
    company_id = Transaction().context.get('company')
    if company_id:
        company = Company(company_id)
        if company.timezone:
            timezone = pytz.timezone(company.timezone)

    dt = datetime.now()
    return datetime.astimezone(dt.replace(tzinfo=pytz.utc), timezone)

它似乎尝试(不正确，除非 TZ=UTC——您应该提交错误报告)执行以下操作:

import tzlocal # $ pip install tzlocal

def get_print_date():
    Company = Pool().get('company.company')
    company_id = Transaction().context.get('company')
    company = company_id and Company(company_id)
    timezone = company and company.timezone and pytz.timezone(company.timezone)
    return datetime.now(timezone or tzlocal.get_localzone())

即，它返回公司时区或您本地时区的当前时间。
