Error: "attr_accessible has been extracted out of Rails 4 in to a gem"

Remaining error message, "...Please use new recommended protection model for params(strong_parameters) or add protected_attributes to your Gemfile to use old one."

I have Googled for resolution, but as I am a beginner to ROR, I am not getting an understandable answer. Could someone help me get through this phase.

btw: This tutorial so much more organized and progressive which makes it very understandable, unlike so many other entities.

Thanks, Larry Norton

I found these helpful for just going ahead using Rails 4.0 but still generally following this tutorial:

I recommend you do two things:

  • Do the ruby on rails ODOT (Todo List) app first. That is written in rails 4 and fits with current versions of ruby and rails.
  • Downgrade your version of rails to 3.2.13 and ruby to 1.9.3 to match the versions in the videos. Trying to do it with Rails 4 will be challenging and frustrating to someone new to rails. I started this in june, and I'm still using rails 3.2.13. I will upgrade eventually, when it's needed.

Thanks Brandon for your quick response and I will go on to the Todo List first.

If you're interested in the devise bits and security, it's here too:

Gets easier after the user profile set-up stuff :)
