Storing an Integer Array in a Django Database

Question

What is the best way to store an array of integers in a django database?

Answer 1

CommaSeparatedIntegerField comes to mind instantly. It is implemented as VARCHAR on most database backends. To be sure though, you may want to skim through django/db/backends/*.

Answer 2

See this answer for a description of a possible alternative version of CommaSeparatedIntegerField that would do more of the work for you (converting from list to string and back). Maybe you could check in with that guy about whether he wrote it already :-)
