Hi,

Is is possible to add this constraint: “null =\> false” and “limit =\> 45”  
like below:

create\_table :movie do |t|  
t.string :name, :null =\> false, :limit =\> 45  
end

…just by using this kind of scaffold command (on Rails 2)?

$ ruby script/generate scaffold Movie name:string

Thanks,

D.

I don’t think so. But you can edit the migration file that the scaffold  
generator produces before running rake db:migrate.
