Question

Anyone have ever use this package ?? github.com/go-playground/validator I want to use

custom struct field label in error message

for example :

type User struct {
Id int64
Username string `validate:"required,max=30"`
Password string `validate:"required,max=30"`
}

and validation error is like this :

{
"User.Password": "Password field is required"
}

I want to use custom label instead of "Password" in above message
like this

"mypass field is required"

any idea??

what exactly are you trying to achieve?

simply instead of using "<struct field> is required " I want to show my custom error I mean now I can use custom error but just can't change that <struct field> to a custom label or string

emm... I wanted to write clean code and not to check every field is nil or for example is int or length is lower than x and .... I mean instead of these checking only giving the fields to that package would be enough I think

what's not clean about this code? func Validate(f Foo) error { if l := len(f.Bar); l < 5 || l > 5 { return errors.New("invalid bar") } switch f.Baz { case "orange", "apple", "banana": // Okay default: return errors.New("invalid baz") } return nil }

So instead of using that package its better to write a few global functions
