paperclip

问题 Am stumbled - went through docs, tutorials, etc, and am not sure what I am doing wrong. Another model in the project is set up for Paperclip and is functional when tested. It saves and retrieves attachment file info into the database, and puts file into a subfolder inside public/system. I basically copied the relevant code over toward the model I am working on The model has the following line: has_attached_file :document The table, which model is linked to, has necessary columns: document

问题 We have already built a rails app that has several users and an image for each of them. Doing all of the dev work on our localhost, we have working seeds for users & photos...but now that we are trying to use S3 for the image storage, we are running into errors during...always during the "seed" step of the migrations, when doing this: rake db:migrate:reset Apologies for the question, but we have have been banging our heads on this for 11 hours, having gone through every related Stack question

问题 I have a paperclip text file attachment (in Rails). My bucket policy is: { "Version": "2008-10-17", "Id": "Policy123", "Statement": [ { "Sid": "Stmt123", "Effect": "Allow", "Principal": { "AWS": "*" }, "Action": [ "s3:GetObjectVersion", "s3:DeleteObject", "s3:DeleteObjectVersion", "s3:GetObject", "s3:PutObject" ], "Resource": "arn:aws:s3:::my_bucket/*" } ] } I want to restrict access to these actions to only be allowed when the request comes from my website. Is it simply a case of updating

问题 I'm writing my first RoR app and currently I'm working on allowing users to upload images. I'm using Paperclip for this purpose. One of the steps involves adding has_attached_file to my model: class MyModel < ActiveRecord::Base #... has_attached_file :picture, styles: { large: "120x150#>", small: "60x75#>" } #... end If I do it like this, everything works smoothly (or so it seems). But I will also need to access the same constant values as integers somewhere else, so I've added a hash: class

问题 I have an "item", which goes through a multi-page creation process. Images are uploaded at step five, and I keep track of the steps by using the attribute "complete". When validating whether an image is attached with paperclip, I get problems using the code below: validates_attachment_presence :pic1, :if => Proc.new { |u| u.complete == "step5"} It seems that I can't access the "complete" attribute, as the active-record object seems to be the paperclip image. Is there a way for me to check at

问题 I've been fighting this for some time now, and your help will certainly be of much appreciation. I've built a method to sign pdf documents which you can find here, and now am only one step away from signing my file. I would like to do this asynchronously, but first i would need to understand how to do it synchronously. So I try 2 different approaches, the after post_process : after_post_process do |receipt| if receipt.receipt_file_changed? require 'aws-sdk' logger.debug("RECEIPT ID: #{self

问题 I have been trying to get paperclip working for a few days now with no luck! From what I am aware this error below is related to imagemagick. I have tried to uninstall and install imagemagick both with macports and manually. Also, have Paperclip.options[:command_path] = "/usr/local/bin" set. It's starting to drive me nuts! Photo /var/folders/A7/A7X8PAnOFsCTHkFpeODoO++++TI/-Tmp-/stream,65411,0.jpeg is not recognized by the 'identify' command. I'm running snow leopard. This appears when I run

问题 I'm using paperclip with my rails 3 app. I want to append a random string, nothing to long or crazy at the end of the file to cache bust the CDN. Anyone know a real simple way to do this? Here is what I have currently: has_attached_file :photo, :styles => { :thumb => "70x70>" }, :storage => :s3, :s3_credentials => "#{Rails.root}/config/s3.yml", :path => "/:rails_env/public/users/:id/:style/:basename.:extension", ..... I would like a file name like FILENAME_31313.png Where 31313 is random

问题 When I try to create a listing in my app with an image this error is thrown: undefined method `call' for "result == false":String. The error occurred after I installed devise gem. But devise shouldn't have anything to do with creating a new listing? The other parts of the app works fine, and I can create new listings without images. Error message NoMethodError in ArtistsController#create undefined method `call' for "result == false":String The method it points to is a callback method in
