I'm not sure I completely understand the question, but if I had a block I'd do something like:
@bar_1 = Bar.get(params[:id => foo_1.id]) #this will grab all the parameters of that bar based on the id then you can do @bar_1.bar #or @bar_1.id #to get any of the parameters of that object Quoting Yuri <[email protected]>: > For example, if Foo belongs to Bar, given foo_1 has a bar.id == 1 > > bar_1 = Bar.get(1) > bar_1b = foo_1.bar > > results in two identical selects.
