paperclip

问题 I made myself a simple rails blogging-type app where I use Paperclip to upload image files.I have everything working fine and dandy. I even have it hooked up to an S3 bucket, etc. Spiffy right?

问题 I was wondering if it is possible to have multiple models all using one central model for its images using paperclip.. So for example I would have a photo model which would use paperclip to store its urls etc In my case I have 2 models, portfolio and post, both of which have a form which allow you to upload images and other attributes to the model. So can both models have a has_many :photos, :dependent => :destroy accepts_nested_attributes_for :photos or would i need to create separate models

问题 I'm trying to delete a plugin I installed for rails (paperclip). But I actually don't have any idea where I can find my local rails installation directory.
