This question already has an answer here:
I'm writing a write method, to write an array of value to InfluxDB
What I would like is to be able to have something like:
func (influxClient *InfluxClient) Write(myArray []interface{}) (error) {
fmt.Print(myArray)
// Insert into DB
return nil
}
Where myArray could be an array with any objects inside
I tried to use myArray []interface{} to ommit myArray's type, but it doesn't work, I get:
Cannot use 'meters' (type []models.Meter) as type []interface{}
Is it possible to achieve it ?
How should I do ?

This happens because []models.Meter and []interface{} are two different types for the Go compiler.
Using interface{} is not a best-practice typically. It would be better to define your own type and use that instead.
Having said that, the quickest solution for your case should be to make Write function a variadic one. Like the example below.
https://play.golang.org/p/KzzFMAjQvRa
func Write(myArray ...interface{}) (error) {
fmt.Printf("Slice: %v
", myArray)
// Insert into DB
return nil
}
It is possible if you copy first to an []interface instance
func main() {
// Copy from your explicit type array
var interfaceSlice []interface{} = make([]interface{}, len(models.Meter))
for i, Modelvalue := range models.Meter {
interfaceSlice[i] = Modelvalue
}
influxClient.Write(interfaceSlice)
}
