rails specify method for redirect_to

Question

During a post for a new model, I am checking for authentication via Authlogic. There is a before_filter on the create request. It is calling require_user. After the user session has been successfully created, the redirect_back_or_default(default) method is called. The problem is, The request needs to be posted to the stored uri. I have tried to store the method and input it into the redirect_to however it isn't working. Any ideas?

# called before successful authentication with before_filter
def require_user
  unless current_user
    store_location
    flash[:notice] = "You must be logged in to access this page"
    redirect_to new_user_session_url
    return false
  end
end

def store_location
  session[:return_to] = request.request_uri
  session[:return_to_method] = request.request_method
end

# called after successful authentication
def redirect_back_or_default(default)
  redirect_to((session[:return_to] ? session[:return_to] : default), :method => session[:return_to_method])
  session[:return_to] = nil
  session[:return_to_method] = nil
end

Answer 1

You can't redirect to a post action, only get actions.

Answer 2

You could store the post object for later processing after authentication, but you really don't want to do that.

Why not simply ask for authentication on the #new method, rather than (or in addition to) the #create? That way the user is authenticated before they fill in the form.
