Hi,

I dumped the schema using rake db\_schema\_dump.  
Now how do I create a migration containing all the data I have in my dev  
db ?

I have seen code to achieve that in the Rails Recipes book and at  
techno-weenie:

Thanks !

Why isn’t there a way to dump content and not only structure ?  
rake db\_dump\_content would seem useful to me, why am I the first one to  
need it ?

And how all of you handle the back data flow: having new data from  
production db go back into development db ? (migrate back to the version  
in prod, import data from prod, migrate to last dev version)
