map duplicates key value pair if not present - dictionary

Question

Following is my structure definition:
type test struct{
Title string
State string
Counts int
}
I want to map struct object members in following way
map[Title:map[State:Counts]]
This is the code which successfully do so
func main() {
r := make(map[string]map[string]int)
r1 := make(map[string]int)
var ts []test
ts = append(ts, test{Title: "Push 1",
State: "Active",
Counts: 20})
ts = append(ts, test{Title: "Push 1",
State: "InActive",
Counts: 20})
ts = append(ts, test{Title: "Push 1",
State: "Checked",
Counts: 20})
ts = append(ts, test{Title: "Push 1",
State: "Active",
Counts: 23})
ts = append(ts, test{Title: "Push 2",
State: "Active",
Counts: 20})
ts = append(ts, test{Title: "Push 2",
State: "InActive",
Counts: 23})
for _, t := range ts {
r1[t.State] = t.Counts
r[t.Title] = r1
}
fmt.Println("struct: ", ts)
fmt.Println("map: ", r)
}
Problem I am facing is Title "Push 2" which does not have a State: Checked is been appended with Count value of previous object.
Following output is as follows
struct: [{Push 1 Active 20} {Push 1 InActive 20} {Push 1 Checked 20} {Push 1 Active 23} {Push 2 Active 20} {Push 2 InActive 23}]
map: map[Push 1:map[Active:20 Checked:20 InActive:23] Push 2:map[Active:20 Checked:20 InActive:23]]
Code I compiled is in go playground.

r := make(map[string]map[string]int) only creates a single map, it has no entries.
r1 := make(map[string]int) also only creates a single map to count states, but you don't need only one, you need a separate one for each distinct title.
So instead of creating that single r1, create inner maps on demand. Range over your structs, and when there is no inner map for its title, then create one and store it in the outer r map.
Like this:
for _, t := range ts {
counts := r[t.Title]
if counts == nil {
counts = make(map[string]int)
r[t.Title] = counts
}
counts[t.State]++
}
Note that the counting operation may simply be counts[t.State]++.
With this the output will be (try it on the Go Playground):
map: map[Push 1:map[Active:2 Checked:1 InActive:1] Push 2:map[Active:1 InActive:1]]
