回形针S3 default_url

Question

I am using s3 with Paperclip which is working well. I am running into problems however with the default_url for missing attachements. I want the default_url to be :attachement/default/:style in the same s3 bucket as the other files. However the default_url when used to generate a missing image is local for the rails app which is not what I want. Eg

/avatar/default/thumb is not what I want for the default, instead I want {s3_base_url}/avatar/default/thumb . I cannot figure out how to do this.

Answer 1

So I solved it, but I am not overly pleased with the solution.

initializers/paperclip.rb Paperclip.interpolates(:s3_bucket) do |attachement, style| Rails.application.config.paperclip_defaults[:s3_credentials][:bucket] end Paperclip.interpolates(:s3_bucket) do |attachement, style| Rails.application.config.paperclip_defaults[:s3_credentials][:bucket] end

Model

default_url: "http://:s3_bucket.s3.amazonaws.com/avatar/default/:style

It would of course be possible to add a fuller interpolation with the complete path to s3, but this is a workable solution.
