start value of model

Hey fellows,

ive running a ror 3 + 1.87 app with 2 models. In one of them i want to have a start value of a string-object (f.e. "User".Object is default named to "Ray"), which should be saved as ID 1. That means if i would set up the database, then i automatically got that Object User with value "Ray" and ID 1. So how can i realize this?

create a rake task to seed the database, which you can run after your migration. here is a railscasts video:

Thank you, Rajinder Yadav!

This is exactly the thing i locked for. Now i typed in this object-creating in the migration and it works.

Best Regards, ray

Note that it is not a good idea to rely on the id of a record having a particular value (1 in this case). If you want a field containing a meaningful number then add another field to contain that number.

Ok, but my idea behind is that i only use this one value. Then i have the option to edit/update it, so there's always one value according to ID 1. No create/delete options available.

Well asides that, i have another problem. I want to associate 2 models: country and events (with country has many events and event belongs to country). I use both in the countries_controller, but i dont know how to create objects in events thorugh this controller. You got any suggestions?

Thanks for your interest, so far.

Then that's a bad idea. Colin is absolutely right: no particular ID value should ever, ever, ever be meaningful.

Have you read the Associations guide yet?

Ok, I'll think about it. Maybe i just create it without relating it to ID1.

Which guide do you mean? I havent read much about associations yet.
