I was moving my budget into Org, and while trying to make it work via
column view and properties I ran into two major impediments.
First, properties can't be calculated from one another ala spreadsheet
or elisp (ie: Property C = Property A + Property B). Thus I had to add
conversion to a dynamic block capturing the column view as formulas.
Second, though column view and captured columns support totaling by
tree hierarchy (ie: parent shows sum of children), I can't add a total
row to the bottom of the dynamic blocks that is preserved across
updates.
Here's a sample:
* Summaries
#+BEGIN: columnview :hlines 3 :id "Budget"
| ITEM | VENDOR | DUE | FREQ | AMOUNT | BIMONTHLY | MONTHLY | YEARLY |
|-----------------------------+--------+-----+------+---------+-----------+---------+-----------+
| *** Optional | | | | -250.00 | -250.00 | -250.00 | -250.00 |
| **** TODO Russell Fun Money | | 1 | 0.5 | -250.00 | -250.00 | -500.00 | -6000.00 |
#+TBLFM: $6=$5*(1/$4)/2;%.2f::$7=$5*(1/$4);%.2f::$8=$5*(1/$4)*12;%.2f
#+END:
No entry has a BIMONTHLY, MONTHLY, or YEARLY property. I used that to
create the columns for my formulas so that I can populate those
numbers. The parent has the wrong sum because it is using the property
values, not summing from the spreadsheet calculation.
* Budget Items
:PROPERTIES:
:COLUMNS: %25ITEM %15VENDOR %3DUE %3FREQ %AMOUNT{+;%.2f} %BIMONTHLY %MONTHLY %YEARLY
:ID: Budget
:END:
** Expenses
:PROPERTIES:
:FREQ: 1
:END:
*** Optional
**** TODO Russell Fun Money
:PROPERTIES:
:DUE: 1
:AMOUNT: -250.00
:FREQ: 0.5
:END:
I've reverted to using spreadsheet with hyperlinks for items so I can
keep notes... I really thought that column view would be superior
though.
Perhaps this will inspire some new features.
Thanks.
