Formula and Rollup fields not retrieved

[chris-sigono]

I successfully used the Notion Python library to extract database table data off our Notion pages, but it seems the only kinds of table fields supported are regular data fields, User fields, and relations (retrieving relation fields is also very very slow per row, but I think that issue was already raised here).

However, if a field is a formula, or a rollup, it is nowhere to be found (or maybe I have overlooked it?). Are there any extra steps necessary to get those fields too?

Unfortunately, it isn't currently possible to get the computed values of formulas or rollups in Notion-py. As far as I can tell (mostly by their absence in API results), these are all computed by Notion's client-side code. If you (or anyone) is able to find somewhere in the Notion API that returns these values, that would be awesome -- and then I could add support. As it is, it would be a lot of work to re-create all the formula/rollup value calculation logic in Python -- though if someone wants to try that and open a PR, that'd be welcome as well! :)

Just a remark: curiously, Notion HTML export does include formula properties, while CSV export does not. I wonder if they render to HTML for HTML export.
