If you setĪ path on a document array element, you do not need to use markModified(). This only affects when you set an array index directly. There are two workarounds:ĭocument#markModified(). Them mongoose never gets notified of the change and so doesn't know to Mongoose doesn't create getters/setters for array indexes without Why don't my changes to arrays get saved when I update an elementĪ. If we get our transactions however, return the data to the client side.Q. If we don't get our transactions, notify the client. So we wrap up new Date().setHours() to become new Date(new Date().setHours()) and we get our date in date-time format to the specific time we want! The point is, that's not the format we want, it's not legible enough. Why? Because as you can see from the snippet above, new Date().setHours() gives us what we want in seconds!(or is it milliseconds? I'm not sure). īut that's not all is it? We still have to wrap our new Date().setHours() in another new Date(). In the same manner, we want to get transactions up to but not beyond the last minute of our endDate, so we type new Date('date').setHours(23,59,59). Here's a short snippet from my PC to explain it further: In the case above, we want to start searching from the very beginning of our start date, so we have new Date('date').setHours(00,00,00). Then when we call new Date('date').setHours() we get the chance to specify the time of day we want to start searching from in hour-minute-second format. When you call new Date() and pass it a date in string format, it returns the date you passed to it in date-time format. Now you may be confused by what this new Date(new Date(startDate).setHours(00, 00, 00)) and this new Date(new Date(endDate).setHours(23, 59, 59)) does.Don't worry, got you covered. getTransactionByDate = async ( req, res ) => We would create a folder called 'models' and within it create a js file called 'transaction.js'.Ĭonst Transaction = require ( '. We would need a Transaction model to hold information about each transaction made and a reference to an arbitrary User model. check that date is in proper format for query.You can be as specific or vague about it as you want, as long as it keeps you on track. It's always a good idea to actually write out in words how you intend to approach the problem. The point here is to define what values we're expecting as request parameters for the query. I won't go through building this as our concern is how to handle using dates on the backend to query the database. You're meant to build a date range component that sends the startDate and the endDate to the backend. Next he goes, 'you know what? Why not just make it a feature on the platform for users to be able to query the database for customers within any range of dates?' Lucky for you, your boss can't be bothered with such tasks and he assigns it to you. Turns out the doors weren't so super after all and management needs a list of all the purchases made within those days for proper damage control. So you work for a sales company called Super Doors as a developer and your boss, a Senior dev has been tasked with finding all customers that were unfortunate enough to purchase some bulletproof doors from the 24th - 30th of the month. Please Note: This tutorial assumes you have a working knowledge of javascript, the node run-time environment, mongoose queries and mongoDB
