MongoDB和PyMongo：Upsert多个值

Question

我想要像这样：...

response = ips.update(
            { "domain":domain }, {"date":date},
            { "$set":{"visitors":visitors, "totalviews":totalViews} }, upsert=True)

但我明白了：

TypeError: update() got multiple values for keyword argument 'upsert'

Answer 1

使用$and运算符来匹配您的更新查询：

db.test.update({"$and": [{date:"date"}, {domain:"domain"}]}, {"$set":{visitors:[]}})
