我们从Python开源项目中，提取了以下20个代码示例，用于说明如何使用django.utils.safestring.SafeBytes()。
def adapt_datetime_warn_on_aware_datetime(value, conv): # Remove this function and rely on the default adapter in Django 2.0. if settings.USE_TZ and timezone.is_aware(value): warnings.warn( "The MySQL database adapter received an aware datetime (%s), " "probably from cursor.execute(). Update your code to pass a " "naive datetime in the database connection's time zone (UTC by " "default).", RemovedInDjango20Warning) # This doesn't account for the database connection's timezone, # which isn't known. (That's why this adapter is deprecated.) value = value.astimezone(timezone.utc).replace(tzinfo=None) return Thing2Literal(value.strftime("%Y-%m-%d %H:%M:%S.%f"), conv) # MySQLdb-1.2.1 returns TIME columns as timedelta -- they are more like # timedelta in terms of actual behavior as they are signed and include days -- # and Django expects time, so we still need to override that. We also need to # add special handling for SafeText and SafeBytes as MySQLdb's type # checking is too tight to catch those (see Django ticket #6052).
def adapt_datetime_with_timezone_support(value, conv): # Equivalent to DateTimeField.get_db_prep_value.
