I’m new with RoR.  
I have a simple migration file:  
class CreateClubs \< ActiveRecord::Migration  
def self.up  
create\_table :clubs do |t|  
t.columns :name, :string  
t.columns :ref, :string  
t.columns :description, :string  
t.columns :local, :string

```
  t.timestamps
end

```

end

def self.down  
drop\_table :clubs  
end  
end

But I get this error message:

[…]  
Wrong number of arguments (2 of 0)  
./db/[…].rb:4:in ‘columns’  
[…]

What am I missing?  
Thank you for your help.

Juste before trying to migrate thie table clubs, I did it fine with  
league:

class CreateLeagues \< ActiveRecord::Migration  
def self.up  
create\_table :leagues do |t|  
t.columns :name, :string  
t.columns :ref, :string  
t.columns :description, :string  
t.columns :category, :string

```
  t.timestamps
end

```

end

def self.down  
drop\_table :leagues  
end  
end

Shouldn’t that be “t.column”? (no ‘s’). Or maybe even…

t.string :name  
…
