And ten days later... SimpleForm goes 0.2

Amazing! SimpleForm was released just 10 days ago it has already 84 followers on GitHub and got a really nice contribution from Andrew Timberlake: attachments support!

How does that work? Simple as it could be (if you do not know what is SimpleForm, I recommend you to read this post first):

class ContactForm < SimpleForm
  attribute :screenshot, :attachment => true
end

And then you set your form to multipart, put a file input and you are done. Your contact form now accepts attachments!

Plus, validations can now be symbols. So we can validate our screenshot attachment just when the contact form type is "UI Bug":

class ContactForm < SimpleForm
  attribute :type
  attribute :screenshot, :attachment => true, :validate => :ui_bug?

  def ui_bug?
    if self.type == 'UI bug' && self.screenshot.nil?
      self.errors.add(:screenshot, "can't be blank when you are reporting an UI bug")
    end
  end
end

And, finally, to conclude the 0.2 release, you can now have request information on your contact form! Some people talked to me that is useful to have the user agent or remote ip from the user included in the contact e-mail, and I agree with them. So now you can do that:

class ContactForm < SimpleForm
  append :remote_ip, :user_agent, :session
end

And when instantiating the form, you just pass the request object:

@contact_form = ContactForm.new(params[:contact_form], request)

And in the contact e-mail received you will have a section with request information, which can be also localized. You can give to append any method that the request object responds to. Holy crap, Batman!
