I'm pretty new to golang and struggling a bit with converting flat database
results into a nested JSON object.
As an example... I have
type item struct {
raceID string
racename string
name string
votes int32
}
type race struct {
raceID string
racename string
racers
}
type racers []racer
type racer struct {
name string
votes int32
}
[]item is what I get back from my db query and I want to convert it into a
json object that matches the race struct.
basically I want to convert
items := []item{
item{"1", "racename1", "scooby", 1000},
item{"1", "racename1", "scrappy", 9000},
item{"1", "racename1", "shaggy", 1000},
item{"2", "racename2", "shaggy", 450},
item{"2", "racename2", "fred", 550},
}
into something like
[{
"raceID": "1",
"racename": "racename1",
"racers": [{
"name": "scooby",
"votes": 1000
}, {
"name": "scrappy",
"votes": 9000
}, {
"name": "shaggy",
"votes": 1000
}]
}, {
"raceID": "2",
"racename": "racename2",
"racers": [{
"name": "shaggy",
"votes": 450
}, {
"name": "fred",
"votes": 550
}]
}]
I'm pretty sure I need to use maps and append some slices... but any
pointing in the right direction would surely be appreciated.
