Once you have the JSON encoded data in a byte slice, pass those bytes into
json.Unmarshal along with a reference to a variable of type AutoGenerated
(or whatever you decide to rename it to). ie:
import "encoding/json"
...
var bytes []byte
var data AutoGenerated
bytes = loadJSONFromDB()
err := json.Unmarshal(bytes, &data)
if err != nil {
//json decoding failed
}
It might be clearer to change AutoGenerated to be a regular struct (rather
than a slice of structs), and define data as an array of AutoGenerated. ie:
type AutoGenerated struct {
and:
var data []AutoGenerated
For more details check the package docs:
