ASIN::Configuration clashing with a Configuration model already in my app

[snoblenet]

Hi there,

My app has a Configuration.rb model. Short of renaming it, how can avoid the clash with ASIN::Configuration?

When I comment out the contents of asin.rb (to allow the app to start), enter the rails console, and type ASIN:Configuration, I see:

Configuration(id: integer, name: string, cached_slug: string, model_id: integer, configured_ram: float, requires: string, created_at: datetime, updated_at: datetime)

These are the attributes of my app's existing Configuration model, not ASIN:Configuration.

Many thanks,

Steven.

hi steven,

you application should not clash in any way, because the gem is using the namespace ASIN to prevent exactly that. unless you are using the same namespace there should not be any problem.

please always provide a stacktrace of the error you get.

Hi there,

Trace pasted below.

I thought it might be that asin.rb was attempting to work with my Configuration class because ASIN, and therefore ASIN:Configuration, had not yet loaded. So I added the 'require' and 'include' statements to asin.rb. But still I get this result:

It's saying the configure method is missing because it's not a method of my Configuration class.

[phoet]

please always provide the code that is causing the error!

[snoblenet]

As in asin.rb? It's:

include ASIN::Client
ASIN::Configuration.configure do |config|
  config.secret        = 'redacted'
  config.key           = 'redacted'
  config.associate_tag = 'redacted'
end

Same result previously with:

ASIN::Configuration.configure do |config|
  config.secret        = 'redacted'
  config.key           = 'redacted'
  config.associate_tag = 'redacted'
end

Gemfile reads:

source 'http://rubygems.org'

  gem 'rails'
  gem 'rake', '0.8.7'
  gem 'ruby-debug19'
  gem 'sqlite3'
  gem 'nokogiri'
  gem 'friendly_id'
  gem 'chronic'
  gem 'syntax'
  gem 'table_parser'
  gem 'rails-backup-migrate'
  gem 'crumble', :require => 'breadcrumb'
  gem 'asin'
  gem 'httpclient'
  gem 'rash'

group :development, :test do
  gem 'rails-backup-migrate'
  gem 'spork'
  gem 'rspec-rails'
  gem 'cucumber-rails'
  gem 'capybara'
  gem 'database_cleaner'
  gem 'haml'
  gem 'haml-rails'
  gem 'compass'
  gem 'compass-susy-plugin'
  gem 'launchy'
  gem 'compass'
  gem 'compass-colors'
  gem 'compass-susy-plugin'
  gem 'rb-fsevent'
end

[phoet]

it might be the case that your ruby version has problems autoloading the asin classes. i saw that lately with some jruby versions.

try this variant:

require 'asin/configuration'

ASIN::Configuration.configure do |config|
  config.secret        = 'redacted'
  config.key           = 'redacted'
  config.associate_tag = 'redacted'
end

if i were you, i would also move the ruby-debug gem to the testing group.

Thanks! But no luck...

[phoet]

you could try moving the configuration-stuff to where you are using asin. i have no idea what the problem is that you are experiencing. maybe you are missing some bundler setup or the like.

i am using this configuration style on my own. have a look here: https://github.com/phoet/basement/blob/master/config/initializers/asin.rb

[snoblenet]

I tried adding ASIN to a new app that did not have my Configuration class and I got this:

[phoet]

if you want to see a working example, i just created a stub with rails 3.1 using asin: https://github.com/phoet/asin_web

[snoblenet]

I moved asin up in the Gemfile to just below sqlite3, commented out httpclient and rash, ran bundle update (upgrading from Raild 3.0.5 to Rails 3.1 in the process), and it started working. :-)

[phoet]

does not make sense to me, but i would not be surprised if bundle just fucked up somehow. not the first time honestly...

[phoet]

hi steven,

i created a little example application with some asin snippets. this might be helpful for problem like yours:

Cool, thx!
