How to Rename a File on S3 with right_aws and Keep Permissions

Because this took way too much time to figure out:

s3=RightAws::S3Interface.new(S3SwfUpload::S3Config.access_key_id, S3SwfUpload::S3Config.secret_access_key)
old_name = "tmp/#{self.video_file_name}"
new_name = original_video_file_path
bucket = S3SwfUpload::S3Config.bucket
(1..5).each do |try|
  begin
    acl_prop = s3.get_acl(bucket, old_name)
    s3.rename(bucket, old_name, new_name)
    s3.put_acl(bucket, new_name, acl_prop[:object])
    break
  rescue Exception => e
    self.video_log += "Problem renaming file, trying again... #{e}\n"
    sleep 1
  end
end

Dealing with Exception Notifier and Rails 2.3.3

I installed Exception Notifier on one of our Apps running Rails 2.3.3 and kept running into this error:

Net::SMTPFatalError (555 5.5.2 Syntax error..

A little bit of insight provided this heads up:

But as of Rails 2.3.3, the from email address will get the angle brackets added, so it can only contain the address.

Rails 2.3.4 is/was supposed to fix that, and includes tests so it will be ensured in future versions.

A quick look at the Exception Notifier README and I tried this:

ExceptionNotifier.sender_address = %("app.error@myapp.com)

Success!

Adding Email and User Verification to AuthLogic

The Session

class UserSession < Authlogic::Session::Base

  validate :check_if_verified



  private



  def check_if_verified

    errors.add(:base, "You have not yet verified your account") unless attempted_record && attempted_record.verified

  end

end

The Migration

class AddVerifiedToUser < ActiveRecord::Migration

  def self.up

    add_column :users, :verified, :boolean, :default => false

  end



  def self.down

    remove_column :users, :verified

  end

end

The User Controller

class UsersController < ApplicationController



  ...



  def create

    @user = User.new(params[:user])

    if @user.save

      flash[:notice] = "Thanks for signing up, we've delivered an email to you with instructions on how to complete your registration!"

      @user.deliver_verification_instructions!

      redirect_to root_url

    else

      render :action => :new

    end

  end

end

The Verification Controller

class UserVerificationsController < ApplicationController



  before_filter :load_user_using_perishable_token



  def show

    if @user

      @user.verify!

      flash[:notice] = "Thank you for verifying your account. You may now login."

    end

    redirect_to root_url

  end



  private



  def load_user_using_perishable_token

    @user = User.find_using_perishable_token(params[:id])

    flash[:notice] = "Unable to find your account." unless @user

  end



end

The User Model

class User < ActiveRecord::Base

  acts_as_authentic



  def deliver_password_reset_instructions!  

    reset_perishable_token!  

    Notifier.deliver_password_reset_instructions(self)  

  end



  def verify!

    self.verified = true

    self.save

  end

The Mailer

class Notifier < ApplicationMailer

  default_url_options[:host] = "www.myurl.org"  



  def verification_instructions(user)

    subject       "Email Verification"

    from          "myurl"

    recipients    user.email

    sent_on       Time.now

    body          :verification_url => user_verification_url(user.perishable_token)

  end

end

Trouble with Deprec Setting up Apache and Passenger

I was getting this error a lot:

VirtualHost *:80 — mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results

The fix:

I had to remove the default site:

cd /etc/apache2/sites-enabled/

sudo rm 000-default

The file is still available here:

/etc/apache2/sites-available/

But is not conflicting with the config files that deprec sets up.

Update to YUI Editor Code View Problem

I over complicated things in my previous solution, and found a better solution while trying to get the WYSIWYG editor to work inside an AJAX form using rails’ remote_form_for.

Using the YUI editor example, set handleSubmit to false and add this right after the MyEditor.render();

// Nate's better Handle Submit
function myHandleFormSubmit(e){ 
  if(state == 'off') {
    myEditor.cleanHTML();
  };
};	
Event.on(myEditor.get('element').form, 'submit', myHandleFormSubmit, myEditor, true);

When doing this and using a AJAX form, try this:

// Nate's better Handle Submit (AJAX version)
function myHandleFormSubmit(e){ 
  if(state == 'off') {
    myEditor.cleanHTML();
  };
  Connect.setForm(e.target);
  Connect.asyncRequest('POST', e.target.action, callback, '_method=put'); 
  Event.stopEvent(e);
};	
var handleSuccess = function(o){ eval(o.responseText); };
var callback = { success:handleSuccess };
Event.on(myEditor.get('element').form, 'submit', myHandleFormSubmit, myEditor, true);

Hope this helps
