I am struggling to access files on S3 with Carrierwave.
In my uploader file doc_uploader.rb I have the following code
storage :file
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
to uplooad "doc" model defined as follow
class Doc < ActiveRecord::Base
belongs_to :user
mount_uploader :doc, DocUploader
end
To access the uploaded file I have the following line of code in a controller
@doc = current_user.docs.order("created_at").last #last file uploaded by user
io = open("#{Rails.root}/public" + @doc.doc.url)
Everything works perfectly locally. Now I want to move my file to S3 in the uploader I use fog and replace
storage :file
by
storage :fog
I adjust my config file carrierwave.rb and uploading works perfectly . However, to access the file I try to use
@doc = current_user.docs.order("created_at").last
io = open("#{@doc.doc.url}")
and I get the following error
No such file or directory @ rb_sysopen - /uploads/doc/doc/11/the_uploaded_file.pdf
Could anyone give me the right syntax to access the file on S3 please? Thanks.
When accessing the asset through the console, it gives you only the path, you might need to append the protocol & host to the @doc.doc.url
, something like:
io = open("http://example.com#{@doc.doc.url}")
Or you can set the asset url on the environment you need to, but this is not really necessary:
config.asset_host = 'http://example.com'
This only applies if you are using the console, on any web view this will not apply, carrierwave seems to handle it
