示例1: toDictionary
# 需要导入模块: from data.DataApi import DataApi [as 别名]
# 或者: from data.DataApi.DataApi import getVisionIdsLikedByUser [as 别名]
def toDictionary(self, options=[], user=None):
'''For packaging to JSON output.
options input is list of Vision.Options when we want more information
fetched from DB and placed into objects
This batches up queries for pictures and comments across all the
visions. Whenever we want to get all this data across a list of
visions, it is good to use VisionList.toDictionary() instead of the
individual toDictionary() calls on objects.
'user' parameter is only used when LIKES in provided as
an option. If it is passed in, we also check whether this user likes
the visions or not.
