I am trying to calculate the number of days and use that value in another calculation in my database. I used this method below which used to to work perfectly but todays its giving me an error db.define_table('invoice', Field('loaning_date', 'date', label=SPAN('Date Loaned', _style="font-weight: bold;"), requires=IS_NOT_EMPTY()), Field('returning_date', 'date', label=SPAN('Date Returned', _style="font-weight: bold;"), requires=IS_NOT_EMPTY()), * #Number of days calculation* *Field('daysLoaned', compute=lambda r: (r['returning_date']-r['loaning_date']).days),* Field('price', 'float', label=SPAN('Price', _style="font-weight: bold;"), requires=IS_MATCH('[0-9]+', error_message=T('Enter Money in Proper Figures'))), Field('totalPrice', compute=lambda r: float(r['price'])* int (r['daysLoaned']), label=SPAN('Total Price', _style="font-weight: bold;")))
Why am i getting this error? How do i rectify it, maybe i am missing something!
