Requiring devise in rspec model spec

I'm using devise in my Admin model like so:

class Admin < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable
end

Functionally, this is working fine. But I want to have specs for my Admin class, so I start to write a spec...

require 'spec_helper'
require 'admin'

describe Admin do
  it 'mumblemumble' do ... end
end

...and then when I go to run the spec, it blows up:

active_record/dynamic_matchers.rb:22:in `method_missing': undefined method `devise' for Admin(Table doesn't exist):Class (NoMethodError)

How do I require Devise so that it's available in my spec? It seems like I should be able to

require 'devise'

in either my spec or my model (preferably my model), but this doesn't fix the issue or change my stack trace. How do I require Devise so that my model has the helper method available? I'm poking around the Devise gem but I'm not finding any clues.

Got it. I run specs with an in-memory instance of sqlite3, so all the db:test:prepare doesn't apply to me. In addition to requiring Devise, it must also be setup/configured.

So in /spec/support/devise.rb:

require 'devise'

Devise.setup do |config|
  require 'devise/orm/active_record'
end

And then in spec_helper.rb:

Dir["./spec/support/**/*.rb"].sort.each {|f| require f}

Yes it seems your test database does not have the admins table. Try this:

bundle exec rake db:migrate db:test:prepare

db:migrate migrates your development database, if there are any pending migrations and db:test:prepare clones your test database according to the development one.

This error

undefined method `devise' for Admin(Table doesn't exist):Class (NoMethodError)

seems to be that you don't have the table in the db? Did you migrate the rake file?

How are you running these? RSpec directly? Or bundle exec rake spec?

There's this in your error: for Admin(Table doesn't exist) which makes me wonder if you have a database yet. The rake task should take care of setting up your world for you.

If that doesn't help, post your spec_helper.rb contents too.

Here's a basic Admin model I have:

class Admin < ActiveRecord::Base
  devise :database_authenticatable, :recoverable, :rememberable,
         :trackable, :validatable
end

And a basic spec:

require 'spec_helper'

describe Admin do
  it { should validate_uniqueness_of(:email) }
end

Works great with vanilla generated rails app and generated devise setup.
