isodate

问题 My MongoDB document is as follows: - { "_id" : 111, "ts" : [ ISODate("2010-08-21T23:13:35.000Z"), ISODate("2011-08-23T09:13:10.000Z"), ISODate("2012-08-26T12:55:51.000Z"), ISODate("2010-08-29T03:11:12.000Z") ] } { "_id" : 112, "ts" : [ ISODate("2010-08-21T23:13:35.000Z"), ISODate("2011-08-23T09:13:10.000Z"), ISODate("2012-08-26T12:55:51.000Z"), ISODate("2010-08-29T03:11:12.000Z") ] } Each date entry indicates a "hit". I am trying to count the number of hits each id had between a certain date

问题 I want to store the current date generated from PHP into MongoDB collection as an ISO date formate.

How to do this? 回答1: You could run the __toString function, or use the sec field __toString will

问题 I have been trying to save the date from javascript side into MongoDB in ISODate format. But it just saves the date field in my MongoDB document in string format. Here is the object I'm sending into the MongoDB to be saved as a document in a given collection. var currentDate = new Date(); postData = { deviceID: deviceID, companyID: companyID, userID: userID, date: currentDate }; Everything works fine except the date field is just saved in String format.
