The end goal of this is that the user gets a monthly email with various statistics (Users logged in, Sites activated, things like hat)</div><div class=""><br class=""></div><div class="">I have settled on Report Stat model and Report Card models. One a month, Report Stat will run and save that data. I take the last 2 report stats (or any 2 report stats, really - thats why I built it this way) and generate the Report Card.</div><div class=""><br class=""></div><div class="">The thing is, most of the data from the Report Card will be the same data from the most recent Report Stat. The users_logged_in from the most recent Report Stat scan will be the number of users_logged_in in the Report Card. There are a few instances where I will want a percentage increase or decrease between Report Stats, I have a integer column ready for that and will just perform simple math on :users_logged_in between my various time frames via various Report Stats.</div><div class=""><br class=""></div><div class="">My issue is, how can I most easily transplant the data from ReportStat into the ReportCard.
