DataValidator

DataValidator is validation everywhere.
For Example, Controller or else.

params = {foo: 'foo', bar: 'bar'}

validator = DataValidator::Validator.new(
  params,
  {foo: {length: {is: 4}}},
  {bar: {presence: true, format: {with: /\A[a-zA-Z]+\z/}}}
)

unless validator.valid?
  @errors = validator.errors
end

@errors
=> {
  foo: ["is the wrong length (should be 4 characters)"],
  bar: ["can't be blank", "is invalid"]
}

DataValidator has almost AR validation logics by default.

• acceptance
• confirmation
• format
• inclusion
• length
• numericality
• presence

DataValidator supports i18n.
If you use rails, you not worry about locale file.

Ex)

# encoding: UTF-8

module DataValidator
  class TestValidator < BaseValidator
    def validate
      if options && values !~ /[^@]+$/
        error_add :invalid_test, test: value
      end
    end
  end
end

BaseValidator set accessors below.

• name : validating parmater name
• value : validating paramter value
• options : validation rules

Please see test case.

An error message subject uses "datavalidator.attribute.#{name}" in i18n locale file or name.
