Custom regex arguments in validations.

[willrax]

Maybe something like this. Would also help eliminate the problem of trying to build the ultimate regex!

rmq.append(UITextField, :user).validates(:email, regex: /whatever/)

[GantMan]

what about rmq.append(UITextField, :gender).validates(:custom, regex: /whatever/)

That way it's not specific, in case you want to chain.

I like the above approach but for the conversation I'll add that you can currently register a custom validator like so:

module RubyMotionQuery
  class Validation
    class << self
      IS_DAVE = Regexp.new('^Dave$')

      @@validation_methods[:is_dave] = lambda do |value, opts|
        Validation.regex_match?(value, IS_DAVE)
      end
    end
  end
end

Then

rmq.append(UITextField, :user).validates(:is_dave)

rmq.validation.valid?("Dave", :is_dave) #=> true

[GantMan]

@vaughankg maybe custom just for people wanting to pass a regex, and

rmq.validation.add_validator(:is_dave) do |value, opts|
  # Whatever here
  true
end

for a convenient way to add custom validators?

[vaughankg]

Looks good. custom is super convieniant and with add_validator you can hide away validation logic in a separate file and use it across your app.
