Hi
I am new to DataMapper. I am trying the examples from getting
started. For some reason I cant access the postgresql database. I
should mention that the ruby I am using is compiled on my computer and
the version is ruby 1.9.1p243. Could any body point the reason I am
unable to see.
Thanks in advance
