undefined method `devise_for' for main:Object

[Paulo Cesar]

Hi everybody, I'm having a problem with devise here. Actually I must
be doing something very lame, because this was supposed to work.

Ok, I have a model User, and configured it to:

devise :database_authenticatable, :confirmable, :recoverable, :rememberable, :trackable, :validatable

Then I created the table with the following migration:

create_table :users do |t|
t.string :domain
t.string :name
t.string :permalink
t.database_authenticatable
t.confirmable
t.recoverable
t.rememberable
t.trackable
t.timestamps
t.timestamps
t.string :logo_file_name
t.string :logo_content_type
t.integer :logo_file_size
t.datetime :logo_updated_at
t.text :about
end

And added to routes.rb the following line:

devise_for :users

And then configured environment with:

config.gem "devise"

But when I run:

User.create(:name => "puelocesar", :email =>
"puelo...@gmail.com", :password => "hild23")

I get the following error:

RuntimeError: Could not find a valid mapping for #<User:0x103580b70>

confirmable.rb:60:in `send_confirmation_instructions'

And when I run rake routes, I get the following error:

rake aborted!
undefined method `devise_for' for main:Object

Can anyone help me on this one?

[Paulo Cesar]

Opa, o problema do user.create eu já achei... É porque eu estava
usando :confirmable, mas ainda não tenho nada de envio de emails
configurado por enquanto.. Desabilitei e funcionou de boa. Agora por
que está dando esse erro no routes?

I guess you need to do map.devise_for instead of devise_for in your config/routes.rb

It would be nice to have this reflected in the README...I just hit the
same problem. Are we seeing a difference between Rails 2.x and Rails
3.0 here?

[José Valim]

Done, README updated. And yes, there is a lot of difference between 2.3 and 3.0.

[Alf Mikula]

Yeah, I was aware that routes have changed in Rails 3.0, but I haven't
had a chance to work with it just yet.

Thanks for the quick response!
