How to validate with nested struct ?

[dederz]

I'm sorry but I don't get the example, that doesn't work, or at least I take it wrong.
If I take the basic struct
type User struct { Id int64 json:"id"Email string json:"email"Detail UserDetail json:"detail"`
}

type UserDetail struct {
Description string json:"description"
Referer int64 json:"referer"
}
Here's the JSON that is posted :{
"email": "toto@toto.io",
"detail": {
"referer":97
}
}`

If I want to apply a rule to the referer field, how can I set that up ?

Thx

An "omitempty" config inside my struct was causing troubles for the validation phase. My bad !
