Mongoose/MongoDB 正则表达式使用变量查找查询

Question

I'm trying to perform a find query in mongoDB (using the mongoose framework with nodejs and express) using a regex expression based on a variable. I'm partially able to query correctly using a static string hard-coded into the code but I need to perform the query using a variable who's value is constantly changing.

The query uses three fields (author, date and updated date) and should go through all documents in a scheme and find all documents where 'date' or 'updated date' is like the variable currentDate (always formatted as YYYY-mm-dd) and where author is authorname.

The main issue is that mongoDB stores the dates with ISO format. On execution the string variable (currentDate (YYYY-mm-dd)) is formatted to ISO which leads it to only "hit" documents with time 00:00.000Z as ISO formats 2015-09-17 to be 2015-09-17 00:00:00.000Z (not taking timezone into consideration).

The query:

var currentDate = yyyy-mm-dd;

Scheme.find({$and:[{'local.author': author},
   {$or: [{'local.date': new RegExp(currentDate)}, 
          {'local.updated_date':new RegExp(currentDate)}]}]}

I've also tried with the $gte and $lte variables (where $gte = date today and &lte = date tomorrow (00:00)) but I couldn't get it to work, I met the wall trying to perform the regex.

I hope there is a brilliant regex expert out there who can help, thank you! :)

Answer 1

I figured it out without all the complexity.

var tomorrow = new Date();
var today = new Date();
tomorrow.setDate(tomorrow.getDate() + 1);
tomorrow.setHours(0,0,0,0);
today.setHours(0,0,0,0);

Scheme.find({$and:[{'local.author': author},{$or: [{'local.date': { $gt: today, $lt: tomorrow } },{'local.updated_date':{ $gte: today, $lt: tomorrow }}]}]}
