MapValidator - A validator for maps
MapValidator is a simple package for validating map values. It allows a bunch of rules to be run through each map key/value checking whether rule is satisfied. All errors from the operation are returned.
Usage
// Define rules
var rules = []Rule{
TypeWithMsg("age", TypeMap, "data must be a map"),
}
// The map to validate
m := map[string]interface{}{
"age": map[string]interface{}{},
}
// Validate does the work returning all errors
errs := Validate(m, rules...)Supported Rules
- RequiredWithMsg(fieldName, errorMsg)
- TypeWithMsg(fieldName, TypeChecker, message)
- EqualStringWithMsg(targetField, cmpVal, msg)
- EqualIntWithMsg(targetField, cmpVal, msg)
- EqualInt32WithMsg(targetField, cmpVal, msg)
- EqualInt64WithMsg(targetField, cmpVal, msg)
- EqualFloat32WithMsg(targetField, cmpVal, msg)
- EqualFloat64WithMsg(targetField, cmpVal, msg)
- Custom(targetField, msg, customFunc func(fieldValue interface{}, fullMap map[string]interface{}) bool)
Supported TypeCheckers
- TypeString
- TypeNumber
- TypeDigit
- TypeMap
- TypeWithMsg
TODO
Being a new package created to quickly solve a problem, it requires many more new rules which will be added over time. Feel free to send PR for new rules :)
