Here's what I'm trying to achieve:
1. Allow users to upload a photo for their profile
2. Allow users to upload photos as blog posts
That being said, here's what I need your expert opinion on:
1. S3, is this still the best choice? Any better easier, Rails3 like
alternatives? Or should I go with S3
2. What Rails 3 Gem supports this best? Allowing me to upload photos
to S3 and assign some type of referenceID throughout the app for USERS
& BlogPostings.
Paperclip makes this desperately easy, even the S3 part. It's a simple configuration change and your files will be saved in S3 versus local storage.
Files are saved as attributes of another model record, so you don't have a separate Image model, you have post_image and user_image, and Paperclip takes care of all the dependencies for you. If you wanted to have multiple pictures per blog post, then you might need a separate model for that, with belongs_to :post and post has_many :photos and Paperclip added to your Photo model as photo_image or something like that.
