| As I get into full swing of using EO's, I'm seeing one place that I know is going to bite me, and that is indexing into the array returned by the parameterless function that returns "many" relationships and assuming a certain order. I'd almost rather not even have that function, at least by default, so that it would force me to always either qualify or sort the results. e.g.
Doing this (assuming the array is sorted appropriately for winIndex: WinAnalysis currWA = currGame.winAnalyses().objectAtIndex(winIndex);
Instead of this: EOQualifier winQual = WinAnalysis.PLACE.eq(winIndex + 1); WinAnalysis currWA = currGame.winAnalyses(winQual).lastObject();
Or am I missing something? I'm just really scared this is going to bite me, and cost me LOTS of debugging time.
Thanks, Jeff |
