CarrierWave file exists?

If you ever wondered how to check for file if exist while you were using carrierwave gem with storage on amazon S3 here is how.

Assuming you have User class:

class User < ActiveRecord::Base
  mount_uploader :avatar, AvatarUploader
end

and uploader class
class AvatarUploader < CarrierWave::Uploader::Base
  storage :fog
end

then only thing that you have to do is this

user = User.first
user.avatar.file.exists?

thats it. I kind of assumed that it should be simple avatar.exist? but you have to get fog instance of file to be able to access exists? method.

Remindcast – my latest project

I had conversation with @mattwilliams about weather and how it would be great to have some tools that will tell you if it will be warmer / colder than yesterday. So you can decide what to wear or what to bring (like umbrella) with you to work. So I build it and you can try it here. Let me know what do you think.

From developer point of view:

Whole thing is build in latest rails. I’m using Google API (that have no documentation) for weather feed, Twitter for messaging and for authentication. The whole thing is hosted on Heroku.
