Hi,

I successfully installed AAA couple days before, and i managed to  
register a uer with it, with no user activation.

but for some strange reason, it stops working for the signup method,  
with i go to the signup page, press submit, it shows an error page,  
what’s wrong? here’s the error page.

undefined method `activation\_code’ for #\<User:0x3b6dbd

Looks like you didn’t run the required migration - or backed it out.

AAA requires a few fields - the error above means it’s looking for  
one that isn’t there.

Hi Jodi,

Thanks for the reply. I thought of that as well, but when i look at  
the Database Migrations-\>migrate-\>006\_create\_users.rb, that field  
isn’t there.

did i skip some steps when i installed it? but it worked for me  
before.

here is the file:

class CreateUsers \< ActiveRecord::Migration  
def self.up  
create\_table “users”, :force =\> true do |t|  
t.column :login, :string  
t.column :email, :string  
t.column :crypted\_password, :string, :limit =\> 40  
t.column :salt, :string, :limit =\> 40  
t.column :created\_at, :datetime  
t.column :updated\_at, :datetime  
t.column :remember\_token, :string  
t.column :remember\_token\_expires\_at, :datetime  
end  
end

def self.down  
drop\_table “users”  
end  
end

I am not sure why this happens, I had the same problem.

Simple fix is to make a new migration:

call it add\_activation\_code and put the following in it.

class AddActivationCode \< ActiveRecord::Migration  
def self.up  
add\_column :users, :activation\_code, :string  
end

def self.down  
remove\_column :users, :activation\_code  
end  
end

Then migrate and you should be OK

Regards

Mikel
