How can I set default value for each column in a Database?

Ruby
1

I created a database in my rails project and want to set default value
for each column. I have read the self.up method of the file
db\migrate\20081123094926_create_bay_infos.rb and thought that this is
where I need to modify. But I don’t know how to do this.

Scroll down to “migrations”, click “learn more”

Search for :default to see some examples

Note that Rails questions are best asked on a Rails mailing list or

(which is an application/framework written in Ruby)
