I am trying to set up the paperclip with amazon s3, I have found a tutorial which is like the following code. What do I have to put as a url and path ?
config.paperclip_defaults = {
:storage => :s3,
:s3_credentials => {
:bucket => ENV['S3_BUCKET_NAME'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
},
:url => ':s3_domain_url',
:path => "/:class/:attachment/:id_partition/:style/:filename"
}
You don't have to worry about touching url, unless you care about whether or not the URL is placed domain-style (bucket-name.s3.amazonaws) or path-style (s3.amazonaws.com/bucket-name). You could not add that in your configurations and it will default to domain-style.
Path tells Paperclip what path to save your attachments. This means in local file system, it will save it under "(model's name)/(attachment name)/(id)/(style e.g. small, thumbnail)/(file name)." It will do the same thing for your bucket, so you'll have all these fun folders to click through if you view your physical bucket. You're free to leave it to the default, or change it if you want your path to be a little shorter.

I'm having trouble with loading images uploaded to s3 via my cloudfront distribution. I can get it to work fine loading straight from s3, but not from cloudfront.
I have set the config.action_controller.asset_host to my distribution url and have set up paperclip
config.paperclip_defaults = {
:storage => :s3,
:s3_host_name => 's3-sa-east-1.amazonaws.com',
:url => ':asset_host',
:s3_credentials => {
:bucket => ENV['S3_BUCKET_NAME'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
}
}
with the appropriate code in the model :path =>
':class/:id/:style/:class:style:id.:extension'
and every time I upload a file and try to access it i get
https://XXXXXX.cloudfront.net/images/:class/:id/:style/:class:style:id.:extension
I honestly can't figure out where the /images/ is coming from that is added between the url and the path. And I would be very greatful for any help or tips to solve this!
Thanks
I have tried many different ways to set up S3 using ENV variables for image uploads and cannot get it to work. I know my keys and bucket name work, because when I put them straight into the code, my images upload correctly. However, when I try to switch to ENV variables, things do not work.
I used the figaro gem, which created application.yml. In that file, I have:
S3_BUCKET_NAME "xxxxx"
AWS_ACCESS_KEY_ID: "AAAAAAAAA"
AWS_SECRET_ACCESS_KEY: "BBBbbbBBBB"
Not sure if there should be any quotation marks there or not, but right now, I have them in. I have tried without, also.
In my model (listing.rb), I have:
has_attached_file :image,
:styles => { :medium => "200x" , :thumb => "100x100" },
:default_url => "default.png",
:storage => :s3,
:s3_credentials => Proc.new{|a| a.instance.s3_credentials }
def s3_credentials
{:bucket => ENV["S3_BUCKET_NAME"], :access_key_id => ENV["AWS_ACCESS_KEY_ID"],
:secret_access_key => ENV["AWS_SECRET_ACCESS_KEY"]
end
Like I said, when I hard code the values into def s3_credentials, everything works fine. It's just when I try to swap out ENV variables that things fall apart.
In paperclip.rb, I have:
Paperclip::Attachment.default_options[:s3_host_name] = 's3-us-west-2.amazonaws.com'
I also have this code in both production.rb and development.rb:
config.paperclip_defaults = {
:storage => :s3,
:s3_credentials => {
:bucket => ENV['S3_BUCKET_NAME'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
}
}
Here is the error message I get when uploading a new image: "The request signature we calculated does not match the signature you provided. Check your key and signing method." On line: "if #listing.save". The ones that were uploaded w/ the credentials hard-coded are still able to be seen in my app.
I'm fairly new to rails and have looked here and other places, including the S3 and paperclip docs, and cannot find a solution that will work. Please let me know if you need to see any other code. I plan on deploying to heroku, if that matters, and saw that figaro is supposed to play nicely with heroku. THANK YOU.
EDIT/UPDATE: For anyone else reading this in the future, Sachin's answer below worked. However, there was a '+' in one of my key IDs. When trying to added the ENV variable via command line, all the characters after the '+' (and including it) were cut off. Simply wrap them in "", and you should be good to go.
Also, I dropped use of the figaro gem, and set up an aws.rb initializer file (per Amazon's instructions). Here are the contents of that file:
AWS.config(
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
)
S3_BUCKET = AWS::S3.new.buckets[ENV['S3_BUCKET']]
And I don't know if this made any difference, but my development.rb and production.rb files now have the following as paperclip defaults:
config.paperclip_defaults = {
:storage => :s3,
:bucket => "your_real_bucket_name_here_in_quotes",
:s3_credentials => {
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
}
}
Also note the switch to referring to the ENV bucket name as S3_BUCKET vs. S3_BUCKET_NAME.
And the code in my model (listing.rb) is now this:
has_attached_file :image, :styles => { :medium => "200x", :thumb "100x100"}, :default_url => "default.png", :storage => :s3, :bucket => "your_real_bucket_name_here_in_quotes"
validates_attachment_content_type :image, :content_type => ["image/jpg", "image/jpeg", "image/png", "image/gif"]
You can do one thing:
You can set this configuration in your development.rb or production.rb
config.paperclip_defaults = {
:storage => :s3,
:s3_credentials => {
:bucket => ENV['S3_BUCKET_NAME'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
}
}
And If you want to set this environment variables into local then use this:
sudo nano ~/.profile
Then add your variables over here
export S3_BUCKET_NAME="your bucket name"
export AWS_ACCESS_KEY_ID="your access key id"
export AWS_SECRET_ACCESS_KEY="your secret access key"
And then reload your ~/.profile with . ~/.profile
Check added variable with echo $S3_BUCKET_NAME
And for Heroku
You can set your variable like:
heroku config:set S3_BUCKET_NAME="your bucket name"
heroku config:set AWS_ACCESS_KEY_ID="your access key id"
heroku config:set AWS_SECRET_ACCESS_KEY="your secret access key"
Check that variables added or not in heroku with heroku config

When I try to use Cloudfront as my CDN the url incorrectly includes the bucket name such as
cloudfronturl.net/bucketname/pathToImage
instead of
cloudfronturl.net/pathToImage
on my image model
:s3_credentials => {
:bucket => ENV['AWS_BUCKET'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY'],
:url => ':s3_domain_url',
:s3_host_name => ENV['CLOUDFRONT_URL']
}
I could try using a gsub on the image urls to replace ['AWS_BUCKET']+"/" but is there a way to configure my cloudfront or paperclip to do this automatically?
This was a pretty silly mistake. The url, path and host alias need to go on the same level as the s3_credentials
:url => ':s3_alias_url',
:s3_host_alias => ENV['CLOUDFRONT_URL'],
:path => ":attachment/:id/:style.:extension",
:s3_credentials => {
:bucket => ENV['AWS_BUCKET'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
}
Seems as if your not specifying a path within your Paperclip config. You may need something like this
path: '/images/folder_name/:id/:style.:extension',
This is what i do and have never encountered the issue you specify with Cloudfront, i use it all the time.
Using a combination of the rails-settings gem and paperclip, I've got my application set up such that one can specify S3 credentials in the database (through an interface in the front end) and can then declare attachments like this;
class Asset < ActiveRecord::Base
has_attached_file :attachment,
:default_url => "content/no-img.jpg",
:s3_credentials => {
:access_key_id => Settings.AWS_ACCESS_KEY_ID,
:secret_access_key => Settings.AWS_SECRET_ACCESS_KEY
}
This works great, but this isn't the only type of attachment in the application (there are other things such as client logos). I'm finding that I need to specify the S3 credentials on every one. I've already tucked some of the defaults away in my app config file;
class Application < Rails::Application
#Paperclip Defaults
config.paperclip_defaults =
{
:storage => :s3,
:bucket => "my-bucket-name"
}
And this all works great, but if I try to pull down the username and password into the app config too, I get the following error;
ActiveRecord::ConnectionNotEstablished (ActiveRecord::ConnectionNotEstablished)
A fairly self explanatory error message, but how do I get around it? If I put the config in the environment files I get the same issue, and if I put them in an initializer like this;
#Paperclip Defaults
MyApp::Application.config.paperclip_defaults =
{
:storage => :s3,
:bucket => "my-bucket-name",
:s3_credentials => {
:access_key_id => RailsSettings::Settings.AWS_ACCESS_KEY_ID,
:secret_access_key => RailsSettings::Settings.AWS_SECRET_ACCESS_KEY
}
}
Then the values don't seem to get picked up and paperclip defaults back to storing the files in my local system directory. Could anyone advise on the best approach to handling this?
EDIT
So after re-reading the documentation I discovered "After Initializers", which gets around the whole active-record not being loaded issue. I have this in my app config;
config.after_initialize do
#Paperclip Defaults
config.paperclip_defaults =
{
:storage => :s3,
:bucket => "my-bucket-name",
:s3_credentials => {
:access_key_id => RailsSettings::Settings.AWS_ACCESS_KEY_ID,
:secret_access_key => RailsSettings::Settings.AWS_SECRET_ACCESS_KEY
}
}
end
And specify this in each model;
has_attached_file :attachment,
:default_url => "content/no-img.jpg",
:path => "#{Rails.env}/:client_name/#{DateTime.now.year}/:name/:basename/:basename-:style.:extension"
yet it still isn't picking up the defaults I specify (it still tries to put them in the public/system folder)
Right, sorted. If anyone has this issue, here's the solution (you basically need to use the "initializers" method to switch active record on before you set the config);
initializer "active_record.initialize_database" do |app|
app.config.paperclip_defaults =
{
:storage => :s3,
:bucket => "my-bucket-name",
:s3_credentials => {
:access_key_id => RailsSettings::Settings.AWS_ACCESS_KEY_ID,
:secret_access_key => RailsSettings::Settings.AWS_SECRET_ACCESS_KEY
}
}
end
I'm trying to set this up using the article on herokus developer site.
https://devcenter.heroku.com/articles/paperclip-s3
# config/environments/production.rb
config.paperclip_defaults = {
:storage => :s3,
:s3_credentials => {
:bucket => ENV['AWS_BUCKET'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY'],
:url => 'https://s3-ap-southeast-2.amazonaws.com'
}
}
However all of my images are pointing to the us http://s3.amazonaws.com/ server
How can i set paperclip to use the sydney server?
UPDATE:
paperclip successfully uploads files to the sydney server, it just wrongly uses the US server rather than the sydney one when trying to view them
Paperclip provides a handful of options, to optimize the configuration of your bucket.
The ones you're interested are url and s3_alias_url.
Your configuration would look like something like this :
config.paperclip_defaults = {
:storage =>:s3,
:s3_credentials => {
:bucket => ENV['AWS_BUCKET'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY'],
},
:url => ':s3_alias_url',
:s3_alias_url => 's3-ap-southeast-2.amazonaws.com'
}
You can find more information and an other example in this google groups discussion.
