I get this error on my tests from the Hartl tutorial section 9.2.3
1) Authentication signin with valid information
Failure/Error: click_button 'Sign in'
ArgumentError:
wrong number of arguments (0 for 1)
# ./app/helpers/sessions_helper.rb:34:in `redirect_back_or'
# ./app/controllers/sessions_controller.rb:11:in `create'
# (eval):2:in `click_button'
# ./spec/requests/authentication_pages_spec.rb:37:in `block (4 levels) in <top (required)>'
It comes from this method in the Sessions Controller:
app/controllers/sesssions_controllers.rb
def create
user = User.find_by_email(params[:session][:email])
if user && user.authenticate(params[:session][:password])
sign_in user
redirect_back_or user
else
flash.now[:error] = "Invalid email/password combination"
render 'new'
end
The 'redirect_back_or' method comes from the session helper: app/helpers/sessions_helper.rb
def redirect_back_or(default)
redirect_to(session[:return_to] || default)
session.delete.(:return_to)
end
Prior to this the Session Controller create method would...
redirect_to user
Changing it to redirect_back_or fails almost all my tests. Using redirect_to user has most of the tests passing.
Here are the relevant tests: spec/requests/authentication_pages_spec.rb
describe "Authorization" do
describe "for non signed in users" do
let(:user) {FactoryGirl.create(:user) }
describe "when attempting to visit a protected page" do
before do
visit edit_user_path(user)
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
end
describe "after signing in" do
it "should render the desired protected page" do
page.should have_selector('title', text: "Edit user")
end
end
end
end
I'm not sure what to do about this. Why am I getting the wrong number of arguments error?
I've gone back over the code but I'm not sure where to go. I feel like I double checked all the code from the book... but I still get this error. Thanks for being another set of eyes. Help me out with this problem thanks.
