Friendly_Id error, unintialized constant

I have a rails app that has Devise-created users that own 'items.' These items have show views and I wanted those show views to have more SEO-friendly URL's. I watched the railscast for the Friendly_Id gem, implemented, but when I go to create a new 'item', it gives me this error:

uninitialized constant Item::FriendlyId

When I attempt to click on an item, it gives me this error:

undefined method `key?' for nil:NilClass

I ran a bundle install. The gem is not in gem assets.

Here is my item model:

 1 class Item < ActiveRecord::Base

I had the same issue. I tried the :require => 'friendly_id' as well as as a server restart. It seems to have fixed the issue.

Thanks @StuartM and @fmendez


I ran into this issue as well. To resolve I wrote a rake task ...

require 'rake'
namespace :posts do
  desc "Save all posts"
  task :save => :environment do
    puts "--- Saving posts ---"
    Post.find_each(&:save)
    puts "All posts have been saved.\n"
  end
end

... executed rake posts:save from my_app/ directory and touch tmp/restart.txt to restart the web server.

Update: Just ran this on my production website. I have to use rake posts:save RAILS_ENV=production otherwise rake raised an exception that it could not find the database adapter.


This is what worked:

Migrate DB to include Slugs on Items, INDEXED Run Migration Rails Console: Item.find_each(&:save)

Then pushed to Heroku and did the same. Worked.
