In the Web2Py book section describing the format attribute of a table there is a brief mention of represent. It seems they serve related but different purposes. Also the label parameter of IS_IN_DB() is also very similar. They all have the same format, anyways (and accept lambda functions)
What are the different situations where these should be used? I have not been able to produce any noticeable results from format, I'm not sure now to use represent, and IS_IN_DB(.., label) formats menu items in the drop down when inserting via appadmin. (I was originally trying to format the references in the appadmin query interface) John
