kandi X-RAY | aico Summary
Abort In COroutines (promises). aico was inspired by redux-saga's Task cancellation. I wanted to use it in promises and found several alternatives. But they are a little bit verbose or lacking. aico writes less and does more. And it supports AbortController and typescript (Although not enough). (I enjoyed watching A.I.C.O on Netflix).

QUESTION
I want to fetch specific key value pairs from mongodb collection with golang dynamically.

Answered 2018-Oct-03 at 08:46Your desired fields are listed in a map[interface{}]interface{}
as values which is not conform to the spec expected by Query.Select()
. The most common type to describe the fields is bson.M
, where the keys should be the names of the fields to retrieve.
So you have to construct e.g. a bson.M
value from your keys, and use that with Query.Select()
. For this we have to find a way to convert the values from interface{}
type to string
. Simplest and most convenient way is to use fmt.Sprint()
for this.
This is an example how you can do that:
