Hello, I’m getting an error while testing my AWDWR2 application : 1. Error: test\_login(LoginControllerTest): TypeError: can’t convert Hash into String /home/foudil/src/ror/depot/vendor/rails/actionpack/lib/ action\_controller/assertions/response\_assertions.rb:115:in `=~' /home/foudil/src/ror/depot/vendor/rails/actionpack/lib/ action_controller/assertions/response_assertions.rb:115:in`assert\_redirected\_to’ /home/foudil/src/ror/depot/vendor/rails/actionpack/lib/ action\_controller/assertions/response\_assertions.rb:114:in `collect' /home/foudil/src/ror/depot/vendor/rails/actionpack/lib/ action_controller/assertions/response_assertions.rb:114:in`assert\_redirected\_to’ /home/foudil/src/ror/depot/vendor/rails/actionpack/lib/ action\_controller/assertions.rb:54:in `clean_backtrace' /home/foudil/src/ror/depot/vendor/rails/actionpack/lib/ action_controller/assertions/response_assertions.rb:54:in`assert\_redirected\_to’ ./test/functional/login\_controller\_test.rb:25:in `test_login' /home/foudil/src/ror/depot/vendor/rails/activerecord/lib/../../ activesupport/lib/active_support/testing/default.rb:7:in`run’ in test/functional/login\_controller\_test.rb: #… def test\_login dave = users(:dave) post :login, :name =\> dave.name, :password =\> ‘secret’ assert\_redirected\_to :action =\> “index” assert\_equal dave.id, session[:user\_id] end #… in response\_assertions.rb: ``` #... ``` 112 rescue ActionController::RoutingError # routing failed us, so match the strings only. 113 msg = build\_message(message, "expected a redirect to \ , found one to \", options, @response.redirect\_url) > 114 url\_regexp = %r{^(\w+://._?(/|$|?))(._)$} > 115 eurl, epath, url, path = [options, > @response.redirect\_url].collect do |url| > 116 u, p = (url\_regexp =~ url) ?

Ok I think I found it : the problem comes from the “post” instruction, not from “assert\_redirect\_to” ! I should have written : ``` post :login, {}, { :name => dave.name, :password => 'secret' } ``` ---

No. This was a wrong solution. because the parameters are passed as session information (non-sense). The original problem comes from ssl\_requirement used in the login controller, which redirects to the same URI, but with ssl. Thus making the assert\_redirected\_to break down. Which leads me to another question : how to test redirection to https://… in the functional tests ? 🙂 Further information underneath : #… class LoginController \< ApplicationController layout “products” before\_filter :authorize, :except =\> :login ssl\_required :login, :add\_user #… def login session[:user\_id] = nil if request.post? user = User.authenticate(params[:name], params[:password]) if user session[:user\_id] = user.id uri = session[:original\_uri] session[:original\_uri] = nil redirect\_to(uri || { :action =\> “index” }) else flash[:notice] = “Nom de l’utilisateur ou mot de passe incorrect” end end end #… @request.headers: REQUEST\_URI: /login/login?name=dave&password=secret SERVER\_PORT: 80 REQUEST\_METHOD: POST @request.response: Status: 302 Found X-Runtime: 0.00129 Location: [https://test.host/login/login?name=dave&password=secret](https://test.host/login/login?name=dave&password=secret) type: text/html; charset=utf-8 cookie: Cache-Control: no-cache Content-Length: 121 ---

This seems vaguely familiar. IIRC, if the parameter passed to redirect\_to is a string, then the parameter passed to assert\_redirected\_to also needs to be a string: rails knows how to compare strings, it knows how to compare hashes, but it won’t compare a string to a hash for you.
