如果在一段时间后未修改文档，如何自动打勾 function

Question

Hello I am working with mongoose/mongodb and have this data structure

{
   step: "Lorem",
   status: "in-progress",
   bool: true,
   startedAt: Date.now(),
   inactive: false
}

how do I make it so if there are no changes to the first three attibutes after a certain period of time inactive is set to true

Thanks for any assistance!

Answer 1

You need an extra field updateAt , everytime step or status or bool changed, you also need to change updateAt .

Finally you can check updateAt .

{
   step: "Lorem",
   status: "in-progress",
   bool: true,
   startedAt: Date.now(),
   updateAt: Date.now(),
   inactive: false
}

Use a CRON, here is some pseudo code

//query
{$lte: updatedAt: today, subtracted by 2months}
//update
{$set: attr to 'whatever you want'}
//db call
db.collection.updateMany(query, update)
