Rails - Jun 2008 - Second question on using RSpec for a simple Rails 2.0 app

Hi,

I’ve got  a Rails 2.0 app “AIMS_1” with one model, “Portfolio”.  (I’m
following David Chelimsky’s 2007  tutorial at
http://blog.davidchelimsky.net/articles/2007/05/14/an-introduction-to-rspec-part-i).
Portfolio has two attributes: :symbol and :name.
With great help from this NG,  I’ve got a neat set of validations
for :symbol.

I want to put together a script that will test the validations as part
of a suite of tests to confirm the app’s validity as I expand it.  For
this purpose,  I added a Q&A directory (actually, “__QA”) under AIMS_1
and populated it with the following portfolio_spec.rb file:

# portfolio_spec.rb
# K:\_Projects\Ruby\_Rails_Apps\AIMS_1\__QA

require ''rubygems''
require ''spec''
require ''spec/story''
require ''K:/_Utilities/ruby186-26_rc2/ruby/lib/ruby/gems/1.8/gems/
activerecord-2.0.2/lib/ActiveRecord''
require ''../app/models/portfolio''

describe Portfolio do
	it "should report any invalid :stock entries" do
		pf = Portfolio.new
	end
end

When I run “spec portfolio_spec.rb” in a Command window I get the
diagnostic:

ActiveRecord::ConnectionNotEstablished in ''Portfolio should report any
invalid :stock entries''.

I expected some error because I’m creating a Portfolio instance
outside the AIMS_1 framework generated by Rails.  I have no idea how
to address this issue.

I’m running ruby 1.8.6, Rails 2.0.2 and SciTE 1.74 over WinXP/SP2.

Any ideas?

Thanks in Advance,
Richard

Are you using the Rspec-Rails plugin?
Cos that should absorb a lot of this capacity for error.
(looks like you just want to require "../../config/environment" or 
something to fix it, so you load rails, rather than just active_record)

but...
http://github.com/dchelimsky/rspec-rails/tree/master

install it as a plugin
(maybe install rspec as a plugin in the same way else it seems to choke 
if your rspec and rspec-rails versions are different)

then run "ruby script/generate rspec"
(don''t ask me why this isnt a rake task "spec:setup".. but it
isn''t)

and you should have a basic spec_helper in place.

then try creating a new model

"ruby script/generate rspec_model Furbie name:string age:integer"

and it should get you a new spec in spec/models/furbie_spec.rb
which should work,
and then make your existing code work the same way...
see what went wrong the first time...

Hi Matthew,

Thank you very much for your excellent help.

First the good news: Your suggestion about requiring the configuration
was spot on!  So I’m a happy camper and will indeed make the post you
requested at the end of your response.

While I plan to continue using the rspec gem for this current
project,  I’m very interested in using the two plug-ins you
recommended on future projects.  However,  I wasn’t able to get rspec
plug-in to install.  Below are the steps I took to:
1. Get the rspec-rails plug-in installed
2. When that failed,  try a different plug-in to show plug-in
installation is working, generally.

I hope you can decipher my current error.  Your unraveling my last
error was neat!

Best wishes,
Richard

I have Rspec frozen in the plugins folder, so I know its the exact same 
version as the Rspec-Rails I''m using.
Thought you might be able to freeze it by doing a "script/plugin 
install",
but clearly not.

But if its working for you, then don''t worry.

Enjoy some spec-ing.

Hi David,

Thanks for that source.  I''ll try your plug-ins after the Fourth.

Best wishes,
