I would like to know how I would add an import csv (from excel) option to appadmin that would update multiple database tables (one of them a relational/intermediate table).
For example, the CSV file would look like this (in excel) ID | posttitle | category | 1 | title1 | cat1, cat2 | 2 | title2 | cat2, cat3 | 3 | title3 | cat1, cat3 | Uploading this would update table 1 with the ID and posttitle, and also the intermediate/relational table with the relationship between posttitle and category (as described here: http://web2py.com/books/default/chapter/29/6#Many-to-many). I'm new to web2py and couldn't find anything in the book, also the questions previously asked already had a good grasp of what to do add a CSV upload feature. I'd appreciate any help as I'm not really sure where to start with this, thanks! --
