Hello!
So I'm having some problems working out some probably really easy
associations in Rails. I've Googled around and read some things on
different Rails forums and blogs, but I just haven't seen many solid
examples.
Anyway, my question is a basic "how do I use RSpec with stubs/mocks
through associations for methods"...
perhaps code would be more clear. Here's my controller:
def create
@article = current_account.article.create(params[:article])
respond_to do |format|
if @article.save
flash[:success] = 'Article was successfully saved.'
format.html { redirect_to(accounts_article_path(@article)) }
else
format.html { render :action => "new" }
end
end
end
And here is my corresponding spec:
describe "handling POST /accounts/articles" do
before(:each) do
@article = mock_model(Article, :to_param => '1')
@account = mock_model(Account)
controller.stub!(:current_account).and_return(@account)
@account.stub!(:articles).and_return(@article)
@article.should_receive(:create)
end
describe "with successful save" do
def do_post
@article.should_receive(:save).and_return(true)
post :create, :article => {}
end
it "should redirect to the new article" do
do_post
response.should redirect_to(accounts_article_url(@article))
end
end
describe "with failed save" do
def do_post
@article.should_receive(:save).and_return(false)
post :create, :article => {}
end
it "should re-render 'new'" do
do_post
response.should render_template('new')
end
end
end
I'm getting a couple of errors from this and I can't tell why. I
have something similar done for non-associated models with no problem.
NoMethodError in 'Accounts::ArticlesController handling POST /
accounts/articles with failed save should re-render 'new''
You have a nil object when you didn't expect it!
I'm sure that speccing associations can't be that bad... I just
don't really know what to look for.
Dave, I can't wait for your book to come out!
Thanks for the help!

Hi David. To write specs for ActiveRecord associations, I find Matthew
Heidemann's #stub_association! extremely helpful. There was a
discussion about it last week, actually:
http://www.ruby-forum.com/topic/171076
I hope that helps. Cheers,
Nick
