Hi, I've come to data_mapper via a programming book that uses version 0.9.11 (in the building of several sinatra applications). I tried to run the code from the book using the latest version of data mapper but it doesn't work. Is there a way to install the older version of data_mapper and to make sure that all the right versions of the dependencies are installed too? The code uses gems like dm-core, dm-timestamps etc.
a) will I need to install the older version of each of these gems individually? b) can you please give me the exact syntax to use For example, I tried gem install data_mapper-0-9-11 but it said it couldn't be found -- You received this message because you are subscribed to the Google Groups "DataMapper" group.
