After the typing the following in my terminal:

# ================================== ./script/generate model Paper user\_id:integer title:string body:text excerpt:text created\_at:datetime updated\_at:datetime

the following migration is created…

==================================  
class CreatePapers \< ActiveRecord::Migration  
def self.up  
create\_table :papers do |t|  
t.integer :user\_id  
t.string :title  
t.text :body  
t.text :excerpt  
t.datetime :created\_at  
t.datetime :updated\_at

```
  t.timestamps
end

```

end

# def self.down drop\_table :papers end end

What happening here…?

Thanks, Matin. I just looked it up in the PeepCode Rails 2 PDF. I just  
changed to Rails 2.0.2 and the syntax of the migration surprised me.

One more question: how does one create a migration from the command  
line? E.g. what do I have to type instead of the old  
‘user\_id:integer’, which is done now with ‘t.reference :user’, or  
‘t.belongs\_to :user’

Thanks,
