paperclip

问题 At the moment I try to replace attachment_fu fileuploading plugin with paperclip. But there are some errors while uploading: My controller looks like this: def create add_breadcrumb 'breadcrumb.upload_file', {:action => :new} puts "BLUBBBBBBBBBBBBBBBBBBBBBBBBBBB" puts params[:upload] @upload = Upload.create(params[:upload]) @upload.lecturer_id = current_user.id if @upload.save flash[:notice] = I18n.t("flash.saved") redirect_to :action => :index else render :action => :new end end and my model

问题 my layout's requirement is to keep all thumbnails at 80px height, not higher, not smaller. In my model I set the style to :thumb=> "500x80>" , so basically almost every picture which is not too wide gets its perfect miniature with 80px height. Sometimes, however, my pictures are narrow and high, so the thumb can have unclickable dimensions of like 5x80. So I dont want to crop pictures as long as thumbnails are not getting crazy narrow, but I think I can make a little sacrifice and crop them

问题 I'm using rbenv to set the ruby version. ruby -v produces the expected 1.9.3 I can do gem install paperclip without a problem. However, when I do bundle install it says: Installing paperclip (3.1.2) Gem::InstallError: paperclip requires Ruby version >= 1.9.2. An error occured while installing paperclip (3.1.2), and Bundler cannot continue. Make sure that `gem install paperclip -v '3.1.2'` succeeds before bundling. but, ruby -v says I'm running 1.9.3. Is bundler runnign as sudo? Have anyone

问题 I've been trying to experiment with having avatars for users in my app, and I've set this up where a user can upload an image using Paperclip. Paperclip has a nice default functionality where you can define a placeholder image when the user has not uploaded an image. What I'm wondering is, is there any way to create a set of placeholder images and have paperclip choose one at random when the associated record is created? IE so not all the "no avatar" icons have to be identical? Thanks! 回答1:

(other apps on same server work normally) does anyone have a clue why that might be happening? i am using some mysql transactions which lock the database also if that might be an issue i read http://www.therailsway.com/2009/4/23/uploading-files but it couldn't be locking server for 2 minutes for a small

问题 I know there's a ton of these asked, but I've tried to follow each one with no luck. There must be some easy mistake that I am overlooking. I'm trying to set up S3 and Paperclip following the Heroku guide and set up local testing following this Words and Code guide. Every time I try to generate a db migration though I get the error: config/environments/development.rb:62:in fetch': key not found: "S3_BUCKET_NAME" (KeyError) These are my files exactly with keys replaced: development.rb config
