QUESTION
I have a problem with updating / modifying the Mongoose embed document.
My function iterate over each document in the collection one-by-one via EachASync
cursor:
ANSWER
Answered 2020-Nov-14 at 09:51I've seen your code and I think you are wrong when you want to update by index.
You think you need the index because you know where is the object whit 'name1' using findIndex()
. But this is not a good way.
Your code loop trough the entire collection, document by document, and look for the array index where name
field is 'name1', 'name2' or 'name3'. And then update the time
value with the actual date, right?
You can do this with a simple mongo
query without loop or JS functions. Check this example
QUESTION
I'm querying a mongo document to retrieve the array info. The thing is my array is inside another array. I don't know how this happened. I'm force to map twice every time to get inside. Anyone knows why?
Here's the mongoose schema:
...ANSWER
Answered 2020-Jun-27 at 01:55I'm assuming your console.log image shows the result of await http.get(urlLaw).
You get nested arrays because in MongoDB and mongoose, "find" returns an array of documents. If you had more than one Law in your Laws collection, it would be clearer since you would see that this second document is returned too.
To sum up, the "outer" array is the array of the documents found by MongoDB and the "inner" array is the section_text field you want.
Use findOne if you want a document to be returned instead of an array of documents.

I am trying to convert type primitive.ObjectID to string in Go. I am using mongo-driver from go.mongodb.org/mongo-driver
I tried using type assertion like
...ANSWER
Answered 2020-Mar-26 at 10:26The error message tells mongoDoc["_id"]
is of type interface{}
which holds a value of type primitive.ObjectID
. This is not a string
, it's a distinct type. You can only type assert primitive.ObjectID
from the interface value.
If you want a string
representation of this MongoDB ObjectId, you may use its ObjectID.Hex()
method to get the hex representation of the ObjectId's bytes:
