NameError: uninitialized constant Object::User

Question

I searched the other posts that had this issue and could not find one that fixed my particular issue. My irb is going crazy. I am trying to change user roles in my database but I can't even get to my users!

irb(main):001:0> User.all
NameError: uninitialized constant Object::User
        from (irb):1
        from c:/Ruby192/bin/irb:12:in `<main>'

It was working fine, stopped working, was fine, and now stopped again. I have a User model and users added. I cannot pinpoint the issue. Let me know what code you need to see. Thanks!

Answer 1

You should run

ruby script/console # Rails < 3

or

rails c  # Rails 3.x

But not (I believe you've just run this)

irb

Valid

You mean console, not server. – Abelmosk

Yep, that worked. Thanks a lot. What a stupid mistake I made. I was told that you can go with either one and it will take you to the same place. Not true. – Preengage

or in my case if you want to start it in production mode you can run $rails c production – Housebreaker

Answer 2

Make sure you're actually using the rails console command rather than just running irb in your project folder.

Is there a good reason why to use rails console rather then irb? Is it possible to access project model Object via irb? So far I'm getting this "NameError: uninitialized constant ...". – Pulsar

irb won't load your Rails environment at all, you have to use the rails console for that. – Abelmosk
