问题 i am having a small problem uploading files to s3 with new carrierwave_direct gem I have followed the instructions for installing and setting up carrierwave_direct, however when i try to upload to s3, the upload begins and then pauses the upload at some point.

问题 I'm having a hard time getting this to work. Right now I'm using the image_tag helper on my view pages. If there isn't an image loaded, I need it to use the fallback from Carrierwave instead of just throwing an error. For my setup I'm using fog for storage, I feel like that might be part of the problem. def default_url asset_path("fallback/default.jpg") end Does Carrierwave just find any image that isn't set? Or is there some special way I'm supposed to grab the image url for it to work? This

问题 I've got the following CarrierWave initializer which works fine on my Heroku/MONGOHQ/GridFS env : CarrierWave.configure do |config| config.storage = :grid_fs uri = URI.parse(ENV['MONGOHQ_URL']) config.grid_fs_database = File.basename(uri.path) config.grid_fs_host = uri.host unless uri.host.blank? config.grid_fs_port = uri.port unless uri.port.blank? config.grid_fs_username = uri.user unless uri.user.blank? config.grid_fs_password = uri.password unless uri.password.blank? config.grid_fs_access

问题 I'm using carrierwave with ImageSorcery in order to handle image uploads and thumbs creation. Everything worked really well until I realized my thumbs were saved without being resized =/ I don't know what causes this and didn't find any solution working for me on the interwebs. I'm using Ruby 2.0.0p247 and here's my code : source 'https://rubygems.org' gem 'thin' gem 'rails', '4.0.0' gem 'sqlite3' gem 'sass-rails', '~> 4.0.0' gem 'uglifier', '>= 1.3.0' gem 'jquery-rails' gem 'fancybox2-rails'

问题 I receive the following error when I try to get image during thumbnail creation: undefined method `file' for nil:NilClass My code: version :thumb do img = ::Magick::Image::read(@file.file).first w = img.columns h = img.rows if w < h process :resize_to_limit => [30, 50] else process :resize_to_limit => [50, 30] end end Any ideas what is this not working? 来源： https://stackoverflow.com/questions/24363366/reading-uploaded-image-undefined-method-file-for-nilnilclass

问题 My create action in ArticlesController seems fine if I create an Article without uploading a picture.

问题 I've been struggling with this for a couple of hours now. When using carrierwave_direct's direct_upload_form_for in my view, it returns me this error: FileUploader Carrierwave Class: class FileUploader < CarrierWave::Uploader::Base include CarrierWaveDirect::Uploader end ManualFile Model: class ManualFile include Mongoid::Document mount_uploader :file, FileUploader field :name, :type => String end UploadController: class UploadController < ApplicationController def manual_new @uploader =

问题 I am using Carrierwave, s3 and fog to upload videos. I added in a file_size_validator file so that videos can't be larger than 5mb. My understanding of how Carrierwave works (please advise if incorrect). Carrierwave saves a copy of the file to the tmp file folder and then performs validations on it so if it passes, the file is uploaded to S3 and the code below removes the tmp file from the local filesystem: video_uploader.rb before :store, :remember_cache_id after :store, :delete_tmp_dir def
