Methods dissapear

[mattiassvedhem]

I'm having trouble locating this error. Example:

In rails console.

User.last.has_role?

Works.

If I change anything in my code however

User.last.has_role?
NoMethodError: undefined method `has_role?' for #User:0x007fcd17d508b8

And I need to restart the console/server

Any Ideas on where to look? I figure it has something to do with the caching?

"If I change anything in my code however" is to vague for me to have an idea of what it could be.
You are welcome to post your project on github somehow, either as a repo or as a Gist and I will take a look.

Sorry for being vague.

What I meant was that if I change anything in my rails code. i.e in my models. Or add permits to cantango for example.

I have troles set up with a string_many association. And trying to use the method in my controller / console, that's pretty much it.

Anyway, here's the trace

irb(main):038:0> User.first.has_role? :admin
  User Load (20.3ms)  SELECT `users`.* FROM `users` LIMIT 1
NoMethodError: undefined method `has_role?' for #<User:0x007fd36727f1e0>

    from /Users/speggey/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1/gems/railties-3.1.1/lib/rails/commands/console.rb:8:in `start'

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

The method worked and returned true, then I changed a permit from can to cannot. If I restart the console the method will be defined.

I recommend that you try one of the other roles solutions compatible with cantango. Try simple_roles or roles_active_record instead for now. I need some more work on troles to make sure plays nice.

In rails console, did you try to use the reload! command after making your changes!?

[mattiassvedhem]

I did use reload!
Ran the specs but couldn't find the issue. I will let you know if I find it.

Thanks!
