Hi everyone, I am trying to a cumulative sum on each page using will_paginate. I don't want the sum of each page, but the cumulative sum. Here is an example:
on Page 1 I have: ----------------------------------------------------------------- | date | in | out | balance | ----------------------------------------------------------------- |12-03-2010| 23.0 | 0.0 | 23.0 | ----------------------------------------------------------------- |12-03-2010| 23.0 | 0.0 | 46.0 | ----------------------------------------------------------------- |12-03-2010| 43.0 | 0.0 | 89.0 | ----------------------------------------------------------------- |12-03-2010| 53.0 | 0.0 | 142.0 | ----------------------------------------------------------------- |12-03-2010| 0.0 | 26.0 | 116.0 | ----------------------------------------------------------------- |12-03-2010| 25.0 | 0.0 | 141.0 | ----------------------------------------------------------------- |12-03-2010| 0.0 | 17.0 | 124.0 | ----------------------------------------------------------------- |12-03-2010| 0.0 | 25.0 | 99.0 | ----------------------------------------------------------------- |12-03-2010| 33.0 | 0.0 | 132.0 | ----------------------------------------------------------------- Total | 200.0 | 68.0 | 132.0 | ----------------------------------------------------------------- On page 2 I have: ----------------------------------------------------------------- | date | in | out | balance | ----------------------------------------------------------------- |12-03-2010| 23.0 | 0.0 | 155.0 | ----------------------------------------------------------------- |12-03-2010| 0.0 | 45.0 | 110.0 | ----------------------------------------------------------------- |12-03-2010| 43.0 | 0.0 | 153.0 | ----------------------------------------------------------------- |12-03-2010| 53.0 | 0.0 | 206.0 | ----------------------------------------------------------------- Total | 319.0 | 113.0 | 206.0 | ----------------------------------------------------------------- etc, etc,etc.... Has anyone done something similar to this before using ActiveRecord and will_paginate? I look forward to hearing from you some suggestions.
