问题 I'm using Carrierwave for uploading image now. All nice, except one, - when I add checkbox for removing uploaded image I get error: "Can't mass-assign protected attributes: remove_image". Form: ... <%= f.check_box :remove_image %> <%= f.label :remove_image, "remove image" %> ... Model: class Manufacturer < ActiveRecord::Base attr_accessible :name, :alias, :short_description, :long_description, :image, :publish, :position, :meta_keywords, :meta_description, :meta_title mount_uploader :image,

问题 I am hoping someone can help me understand this. I have a base64 string for an image: "data:image/jpeg;base64,/9j/4AAQSkZJRgABA..." I would like to send it using ember's createRecord and commit(): this.get('store').createRecord(Emb.Painting, {name: newName, image: newImage}); Then I want to convert it to StringIO for carrierwave and save it: StringIO.class_eval { def original_filename; "stringiohaxx.jpg"; end } io = StringIO.new(Base64.decode64(params[:painting][:image])) @painting = Painting

问题 I'm using Carrierwave to upload files, and I have it working. My issue is attempting to change the name of the uploaded file. In the generated uploader.rb there is a method I think I should be using def filename "something.jpg" if original_filename basename = "what"+orginal_filename if original_filename, works basename = (0...8).map{65.+(rand(25)).chr}.join if original_filename # will create a random name for each version, e.g. the orginal, the thumb, and the filename in the db, useless end I

问题 I use carrierwave 0.9.0 with Rails 4 and I'm trying to make a custom error message. After doing some search, I found this answer: en: errors: messages: extension_white_list_error: 'My Custom Message' I tried this by going to config/locales/en.yml then adding the code above, but nothing changed. The error message is still the same. There is also the same issue on github here, but no answers, I think this problem is specific just with Rails 4 but not sure, have you the same problem when you use

问题 I got this error Missing required arguments: aws_access_key_id, aws_secret_access_key . That seems weird because I already added carrierwave.rb in initializers folder. The access/secret key works perfectly when I use aws-sdk CarrierWave.configure do |config| config.fog_credentials = { provider: "AWS", aws_access_key_id: ENV["PUB-KEY"], aws_secret_access_key: ENV["SEC-KEY"] } config.fog_directory = ENV["mybucket"] end 回答1: Here's what my working one looks like: CarrierWave.configure do |config

问题 I am using carrierwave to upload images to amazon s3. This works great on development, but not when I push it to my server (engineyard cloud trial). The process works fine, no errors are thrown, and a link is given back. However, the actual image is corrupted, somehow. Here's one, for example: https://s3.amazonaws.com/ZenBucket/uploads/goal/photo/30/guinness-toucan.jpg Can anyone tell me how it's being corrupted, or what could be doing it? Edit: The first image upload attempt after deploying

问题 I have a User Model and have a Image model with carrierwave. I want to limit the amount of images an user could upload because I have a second form where the user goes to upload de images and I want him to able to upload only 3 images. Is there an elegante solution for this? Or do I have to make a custom validator that counts the amount of images the user as? 回答1: I guess your model is somehow similar to that : class User has_many :photos end class Photo belongs_to :user mount_uploader :file,
