paperclip

问题 I just updated the dimensions of an image thumbnail, and have been working on updating 28,000 photo objects.

问题 I'm clueless as to what's going on with this because I have another app on the same server that receives and saves uploads just fine. No error messages, Paperclip even say's in the log it's saving the attachments. But the attachments don't get saved. Thoughts anyone? Also how would I test for this using RSpec/Capybara, because apparently my tests don't cover this. Running Paperclip 2.3.12, Rails 3.0.9, REE1.8.7 Production on RHEL5 / Apache , but runs on a different user than my other app's

问题 I am new to paperclip, and I wanted to see how it would work. I generated a simple model Monkey and got the following: rails g scaffold monkey description age:datetime rails g paperclip monkey facepic rake db:migrate Model class Monkey< ActiveRecord::Base has_attached_file :facepic, :styles => { :medium => "300x300>", :thumb => "100x100>" } end View new/edit <%= form_for @monkey, :url => monkies_path, :html => { :multipart => true } do |f| %> ... <div class="field"> <%= f.label :facepic %><br

问题 I have a page where I can view a product, and directly from this page the user can add and remove multiple images associated with the product. I'm using paperclip in a form to upload new file. Because multiple images can be saved for a product I created an image model belonging to the product model. It's not possible to use the default paperclip file input because of the association. My solution below is working, but I'm wondering if there's a better way in rails to accomplish this without
