Question

Here’s what I’m using to create my database:

DataMapper.setup(:default,"sqlite://my.db")

   class Model1

      property :some_prop,String
      ...
      property :other_prop,String
   end

   DataMapper.auto_upgrade!

I’m using this in combination with Sinatra. Everything’s ok while the script is running, I can use my objects normally. However, I see no file my.db on the disk, and everytime I’m restarting the application, I start from scratch, without any objects.

What am I doing wrong?

Answer 1

Try putting the full path in there (note there are 3 forward slashes):

DataMapper.setup(:default, "sqlite:///path/to/my/database/my.db")

Then you should see my.db under /path/to/my/database/
