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.
So playing around with things, it appears I didn’t remember to put in
the
and_return(@article)… so I changed my before to look something like
this:
describe “handling POST /accounts/article” 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.stub!(:new).and_return(@article) @article.should_receive(:new).and_return(@article)
end
Now, I still don’t entirely understand what I’m doing, so if someone can
explain it or point me to a good blog article, I’d greatly appreciate
it.
Like I said before though, I’ve looked around and read over the
documentation several times, but for some reason, my mind just isn’t
grasping the associations
