How do I get data of last few days, weeks, months, years in mongodb for admin dashboard?

I have an order collection. I want to get order data of the last 7 days, last 7 weeks, last 7 months and last 7 years. For example, if today is Tuesday, I want to know how many orders did I have on tuesday, how many orders on monday and similarly all days until last tuesday. Similarly I want data for all units I mentioned above. How do I achieve this?

I tried using $addFields with $dayOfTheYear, $week, $month and then grouping it inside facet pipeline accordingly but I ran into some issues cause I can only go within a year. I want a better, more straight forward method that just gives me the result of last 7 units without restriction of current year.

Hi @Anand_S2,

Please provide the following information:

  • Sample documents
  • Expected output
  • Output from what you have attempted
  • Clarification on “for admin dashboard” (As per your post title) - Are you referring to a MongoDB Chart of some sort?
  • MongoDB version

Expected Output

{
// only count documents which have status as "Completed'
orderCountsOfLastSevenDays: { tue: 1, wed: 3, thu: 5, fri: 3, sat: 7, sun: 10, mon: 6, tue: 5 },
orderCountsOfLastSevenMonths: { oct: 20, nov: 30, dec: 35, jan: 60, feb: 30, mar: 30, apr: 43 },
//a week is from monday to sunday
orderCountsOfLastSevenWeeks: { week1: 10, week2: 15, week3: 13, week4: 20, week5: 10, week6: 21, week7: 25 }
}

//or it can be as simple as each orderCounts being an array of numbers without those keys

Clarification on ‘for admin dashboard’
I am not refering to MongoDB charts, I was just saying this data is for charts in a dashboard for our business

MongoDB version: 6.0.4

I have the same problem. Please post the query if you have resolved it
