generate new line on the database
on the database, we have an actors table (one lin by actor) which has a manyToManyField linked to the invoicing table. An actor can have several lines on invoicing table (one line by year). We would like to automatically add new lines (one by actor) on the invoicing table at the begining of the year. We have to add an amount wich will be calculated with several indicators.
Should we do that on the client side or on the server side ?
