Per the instructions in lib/carrierwave/storage/s3.rb I have the following in my initialization file (config/initializers/carrierwave_fog.rb): CarrierWave.configure do |config| config.s3_access_key_id = "xxxxx" config.s3_secret_access_key = "xxxxx" config.s3_bucket = "mybucket" #already created in my S3 account end In photo_uploader.rb I have: class PhotoUploader <

问题 I want to run some methods after the upload of a file has been completed via Carrierwave. Carrierwave includes several callback methods detailed here. I'm planning on using the :store callback. That's great, but it requires me to run the callback method in the Uploader object instance. This isn't the end of the world, but I want to keep all the logic inside of my parent Model. My question is: How should I be referencing the parent model from the Uploader? I don't see anything obvious in the

问题 So im a total newbie and going through Michael Hartl's rails tutorial. Ive become totally stuck when trying to config picture uploads using carrierwave, fog-aws to S3 AWS. When pushing to heroku I get the following error: LoadError: cannot load such file -- fog As a side note i've tried using the exact same code in development mode, rails server works just fine and I am able to upload files to AWS successfully.

问题 I've followed the deployment instructions from Carrierwave with how to deploy on Heroku for a Rails app using Amazon S3: https://github.com/carrierwaveuploader/carrierwave/wiki/How-to%3A-Make-Carrierwave-work-on-Heroku I've added the extra line to config.ru and created the config/initializers/carrierwave.rb file, but no success. Below is the carrierwave initializer, with keys redacted. Is this correctly setup? What else do I need to do? Any step-by-step guides to help me implement this?

问题 I've an uploader where I've implement the #filename method to get a custom and unique filename but it looks like this method is ignored before saving the file (I'm uploading to rackspace with the fog gem) Here is the uploader: class MyImageUploader < CarrierWave::Uploader::Base include CarrierWave::RMagick ... def filename if original_filename.present?

问题 I have an application that reads the content of a file and indexes it. I was storing them in the disk itself, but now I'm using Amazon S3, so the following method doesn't work anymore.
