@ -14,26 +14,46 @@ It has the following **unique** features:
- Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated.
- Handles type interface by determining it's underlying type prior to validation.
- Handles custom field types such as sql driver Valuer see [Valuer](https://golang.org/src/database/sql/driver/types.go?s=1210:1293#L29)
- Alias validation tags, which allows for mapping of several validations to a single tag for easier defining of validations on structs
Installation
------------
Use go get.
go get gopkg.in/bluesuncorp/validator.v7
go get gopkg.in/bluesuncorp/validator.v8
or to update
go get -u gopkg.in/bluesuncorp/validator.v7
go get -u gopkg.in/bluesuncorp/validator.v8
Then import the validator package into your own code.
import "gopkg.in/bluesuncorp/validator.v7"
import "gopkg.in/bluesuncorp/validator.v8"
Error Return Value
-------
Validation functions return type error
They return type error to avoid the issue discussed in the following, where err is always != nil:
* http://stackoverflow.com/a/29138676/3158232
* https://github.com/bluesuncorp/validator/issues/134
validator only returns nil or ValidationErrors as type error; so in you code all you need to do
is check if the error returned is not nil, and if it's not type cast it to type ValidationErrors
like so:
```go
err := validate.Struct(mystruct)
validationErrors := err.(validator.ValidationErrors)
```
Usage and documentation
------
Please see http://godoc.org/gopkg.in/bluesuncorp/validator.v7 for detailed usage docs.

Validation functions return type error
Doing things this way is actually the way the standard library does, see the file.Open
method here: https://golang.org/pkg/os/#Open.
They return type error to avoid the issue discussed in the following, where err is always != nil:
http://stackoverflow.com/a/29138676/3158232
https://github.com/bluesuncorp/validator/issues/134
validator only returns nil or ValidationErrors as type error; so in you code all you need to do
is check if the error returned is not nil, and if it's not type cast it to type ValidationErrors
like so err.(validator.ValidationErrors)

Alias Validators and Tags
NOTE: when returning an error the tag returned in FieldError will be
the alias tag unless the dive tag is part of the alias; everything after the
dive tag is not reported as the alias tag. Also the ActualTag in the before case
will be the actual tag within the alias that failed.
Here is a list of the current built in alias tags:
