Hi all,
I''m hoping someone can help me here I''m trying to carry out
functional
testing, my IDE is NetBeans 6.8 and I''ve found that any tests on
controllers who have to deal with related data are failing.
I''ve got a controller called business that hold the details of a
business along with its owner which is a user created using authlogic.
In the get_index, and show_business sections of the test I''m getting an
ActionView error because I''ve changed the related view to display the
related data not the actualy foreign key e.g. it shows
''Graham'' not 1
The errors reported are
test_should_get_index(BusinessesControllerTest):
ActionView::TemplateError: undefined method `login'' for nil:NilClass
On line #24 of app/views/businesses/index.html.erb
21: <td><%=h business.country %></td>
22: <td><%=h business.longitude %></td>
23: <td><%=h business.lattitude %></td>
24: <td><%=h business.user.login %></td>
25: <td><%= link_to ''Show'', business
%></td>
26: <td><%= link_to ''Edit'',
edit_business_path(business) %></td>
27: <td><%= link_to ''Destroy'', business,
:confirm => ''Are you
sure?'', :method => :delete %></td>
test_should_show_business(BusinessesControllerTest):
ActionView::TemplateError: undefined method `login'' for nil:NilClass
On line #38 of app/views/businesses/show.html.erb
35:
36: <p>
37: <b>Business Owner:</b>
38: <%=h @business.user.login%>
39: </p>
40:
41: <%= link_to ''Edit'', edit_business_path(@business)
%> |
I am also getting a run time error on the get_new test as it can''t save
a record because there is no logged in user.
I''ve read that these failures are normal because of the changes I made
ocurred after ROR created the test files but not how to resolve the
issues.
Can anyone give me some pointers on this???
Thanks,
Graham

How did you write your Business and User models?
What you are trying to do is as simple as a relation between User and
Business model. And i guess it should be like the following:
class User < AR::B
has_many :businesses # or
# has_one :business
end
class Business < AR::B
belong_to :user
end
Now if you have these setup as expected then what about your yml
files? Did you made the exact relationship there? If you have
businesses.yml and users.yml then a business object should have a
user_id which should refer a user id from users.yml
With a proper relation with user_id of businesses table with id of
users table would return a user object if you call business.user and
then you can call whatever method of that user object.
However, could you please explain what is the user.login method doing
here??
As you said>
> foreign key e.g. it shows ''Graham'' not 1
It should be like user.name or user.first_name or something else. But
login method doesnt seem that intuitive or im missing something?
Let me know the status...

I''ve setup my business and user models as follows class Business < ActiveRecord::Base belongs_to :user class User < ActiveRecord::Base has_one :business In relation to the yml files please pardon my ignorance I take it that its the file in the Fixtures folder if so here they are please note the user_id I had to add myself. one: id: 1 name: Graham''s Bar user_id: 1 address: 112 O''Connell Street province: Dublin 1 city: Dublin country: Ireland longitude: 1.5 lattitude: 1.5 two: id: 2 name: Joe''s Bar user_id: 2 address: 12 Grafton Street province: Dublin 2 city: Dublin country: Ireland longitude: 22.4 lattitude: 22.5 In relation to the user.login I had to add that to display the users name not the id field data. The field login is setup by default by authlogic. If I''m leaving anything that you need out please let me know.

There are parts of Rails that he and the core team simply got wrong architecturally.

They''re practical tools that improve noticeably on what Rails already offers. I have used fixtures and controller tests, and I know that I''m better off now that I''ve replaced them. Use what works for you. But don''t claim "academic masturbation" in the face of many of us who know it not to be true. And with that, I''m done, unless you have specific issues with these tools that you''d like to discuss. FUD and innuendo don''t do much for me.> > > -- > Greg Donald > destiney.com | gregdonald.comBest, -- Marnen Laibow-Koser http://www.marnen.org marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

There''s no reason to to replace what''s already there and already works great. Two others help write the book.

A few observations though: 1) I own every edition of AWDWR, including the latest version covering Rails 3. Each edition is an evolution of its predecessor. It started with test/unit and fixtures since that''s what came with Ruby and was baked into rails. Although alternatives have appeared, the book has tended to stay there, probably because a) it''s talking about what comes with rails, and b) it''s easier not to rewrite sections when you don''t have to. There are also pedagogical concerns. AWDWR is primarily an introduction to rails. Just like they teach physics in high school without recourse to calculus, doesn''t mean that calculus isn''t a very useful tool when you really start to practice Physics, some advanced topics are best left to later courses. 2) Rails 3 has refactored rails so that test/unit isn''t closely coupled. If you install the rspec-rails and cucumber plugins, for example the rails3 generators will automatically produce rspec specs and cucumber features. Since the 4th edition of AWDWR is in an early beta form, I don''t know how much Sam will cover this. Again, there''s a certain amount of inertia. For one thing he has made and effort to bring testing earlier in the depot example, which I like. However he hasn''t changed the flow to use test driven design, which is and should be standard practice for rails developers whether they are using test/unit, rspec, shoulda ..., I understand that just breaking up the testing chapter and reshuffling the chapters. It''s better but it still comes across as fostering code first then test, which I doubt the authors fully endorse. 3) Fixtures. There are lots of experience Rails developers who have come to the conclusion that fixtures really s*ck. Hence all the fixture replacement plugins. In my experience, these days fixture replacements tend to be used much more than the built-in rails fixtures in real-world rails projects, not that there''s much of consensus on which one is best. If fixtures work for you find, if not... 4) RSpec and Cucumber are seen as very powerful tools by a wide range of Rubyists and Rails app developers. Far from spilling our intellectual seeds on the ground, as your colorful characterization would have it, we are being very prolific, thank you! 5) I would argue that the fact that Dave Thomas is the publisher of "The RSpec Book", which really should be called the RSpec and Cucumber book, constitutes an endorsement of RSspec and Cucumber. But then as they say in Rome, de gustibus non est disputandum!
