Inside the model the date is defined as : xDate : { type: Date.now, required: true } I pass the current Date as : var d = new Date(); var temp = d.toISOString(); var subStr = temp.substr(10,temp.length - 1); var curDate = temp.replace(subStr, "T00:00:00.000Z"); console.log(curDate); However the date is stored as an ISO String inside the MongoDB schema. I try to query

问题 I am building a fairly simple application on the MEAN stack and I am really out of my depth, especially when it comes to mongoose. I have found the mongoose documentation very difficult to wrap my head around and cannot find answers anywhere else. My issue is this: I have a bunch of users, these users have repositories and the repositories have repository providers (GitHub, BitBucket etc). A user has many repositories and a repository has one repository type. My user file contains the

问题 I'm developing an intranet for a company under MEAN.js . I was wondering if there's a way to use MySQL along with MEAN.js and keep using MongoDB. Primarily I'll use mongo for heavy data, such as pdf's, videos, music, etc. I'll use MySQL for structured data such as users, profiles, statistics info, etc. The main question is how to do it, and also would like some advices.
