Rails redirect_to new behaviour with Ruby 2.2 / Rails 4.2?

Rails
1

Trying to upgrade from Ruby 2.0 / Rails 4.0 to Ruby 2.2 / Rails 4.2, I
face a surprising error when logging into my application (based on Rails
Tutorial by M. Hartl):

Controller: SessionsController#create
Instruction: redirect_to root_url
Error message: wrong number of arguments (2 for 1)

Here is the sessions controller:

class SessionsController < ApplicationController

def new
end

def create
user = User.find_by_login(params[:session][:login])
if user && user.authenticate(params[:session][:password])
sign_in user
redirect_to root_url
else
flash.now[:error] = ‘Invalid login/password combination’
render ‘new’
end
end

def destroy
sign_out
redirect_to root_url
end

end

Here is the routes file:

ODQStairs::Application.routes.draw do

resources :requests

#static pages
get ‘/help’, to: “static_pages#help”
get ‘/about’, to: “static_pages#about”
get ‘/contact’, to: “static_pages#contact”

#root definition
root to: “dashboards#home”

#routes
resources :sessions, only: [:new, :create, :destroy]
get ‘/signin’, to: ‘sessions#new’ , via: :get
match ‘/signout’, to: ‘sessions#destroy’, via: :delete

resources :parameters_lists do
resources :parameters
end
…

I did not find anything in Rails upgrade guides regarding the
redirect_to function. Your help is welcome! Thanks!

Could you copy/paste the full error message from the terminal please?

The full console message is :

ArgumentError (wrong number of arguments (2 for 1)):
app/controllers/sessions_controller.rb:10:in `create’

See the attached screenshot.

Thanks for your help !

Add gem ‘responders’ to your Gemfile.
redirect_to was moved to that.

probly the redirect_to is not clean. check its code. (compare w the
newly installed railstutorial)
usually when you upgrade rails/ruby to maj ver, youd also want to
upgrade the gems…

kind regards --botp

It most certainly wasn’t (responders gem is about respond_with/ class
level respond_to)

It would have been better to copy/paste the error from the server
terminal window as I asked, remember many still pay for bandwidth,
particularly on mobile devices.

That is rather odd, can you copy/paste the result of
rake routes
here please.

Assuming that does not show anything odd I would next try to home in
on the exact item that is causing the problem, possibly:

  1. comment out the offending line and check that the error moves to
    the second redirect_to just below.
  2. modify the line first so as to redirect_to a plain string url, if
    that fails in the same way it is an issue with redirect_to
  3. if 2 now passes then try using root_url with a different function
    and see if that passes.

Also possibly useful I think to post Gemfile.lock here.

As suggested bopt, I had a look at my gems versions, I actually missed a
few. I updated to the last versions, following gems have been installed:
Installing websocket 1.2.1
Installing selenium-webdriver 2.44.0
Installing bootstrap-will_paginate 0.0.10
Installing sass 3.4.12
Installing annotate 2.6.5
Installing globalid 0.3.3

This solved the issue.

Thanks for your help!

Best regards,

Fred
