Heroku NoMethodError - Paperclip - ruby-on-rails

Question

Edit2~
Hi All,
I solved my previous new error by changing my model file according to this. I don't know why but it solved it. I now have this error to deal with. : |
There is no key? method in my controller. Do I need to include it? If so, how?
NoMethodError in ProductPhotosController#index
undefined method `key?' for nil:NilClass

Edit~
Heroku Load Error - Paperclip
The problem was a syntax error I found in my model. I have a new problem now
What I did:
This problem occurred on the local host with sqlite3 as db. I logged onto the s3 module and uploaded all the relevant folders that were once in 'public/system/images/000/000/' to the folder 'images' in the bucket choco_photos on s3. I also changed the URL and PATH to reflect it but I'm pretty sure I did something wrong.
Do the PATH AND URL file reflect where the image is stored and accessed on S3?
I will mention I am still confused about the configurations even after watching the railscast on paperclip. I checked the docs AWS recommended but it didn't help. To be specific, I was confused by this statement:
# File 'lib/paperclip/storage/s3.rb', line 203
def s3_object style_name = default_style
s3_bucket.objects[path(style_name).sub(%r{^/},'')]
end
Any and all help is appreciated.

Answer 1

For question 1: Heroku runs 1.9.2 on the Cedar stack, which you are on based on your app's URL. I believe the 1.9.1 is just a directory and does not actually related to the version ... I get the same "mismatch" between 1.9.1 in a folder name and my system actually running 1.9.2 or 1.9.3 (and I only run 1.9.2 or 1.9.3 via RVM).
You can verify the Heroku version by opening a Rails console on heroku ...
Open Terminal/Console
Navigate to your project directory
Type: heroku run console (this assumes you've installed the heroku gem or CLI tools)
Once the console loads, type: RUBY_VERSION (you should see either 1.9.2 or 1.9.3 output)
For the question 2: I had to alter how I had paperclip in my Gemfile. I use this and it works on Cedar:
gem 'paperclip', "~> 3.0"
gem "aws-sdk"
And in my related model:
has_attached_file :photo,
:storage => :s3,
:s3_credentials => "#{Rails.root}/config/s3.yml",
:styles => {
:large => "600x480",
:medium => "330x230",
:small => "210x150",
:thumb => "90x90"
},
:path => 'images/products/:style/:filename'
And in my s3.yml file:
development:
access_key_id: MYKEY
secret_access_key: MYSUPERSECRETACCESSKEY
bucket: bucketname
Hope that helps!
