The custom validation on the example is not working.
func init() {
// Min(1) set de minimun integer value
binding.AddRule(&binding.Rule{
IsMatch: func(rule string) bool {
return strings.HasPrefix(rule, "Min(")
},
IsValid: func(errs binding.Errors, name string, v interface{}) (bool, binding.Errors) {
num, ok := v.(int)
if !ok {
return false, errs
}
min, _ := strconv.Atoi(rule[4 : len(rule)-1])
if num < min {
errs.Add([]string{name}, "MinimumValue", "Value is too small")
return false, errs
}
return true, errs
},
})
}On compile we have this error.
pkg/webui/extravalidations.go:22: undefined: rule
There is no "rule" variable defined inside IsValid function. But I need build custom rules similars to the Min(10) example . How can I access to the rule definition in the IsValid function?
