Change DB data type and limited decimals
Rails3.1.3
I have db type,
startp:integer
I need to change it to float. More specifically,
1.2, 45.1, 143.8 ...
I have two questions:
1. Is removing and adding the field through migration the only way?
in other words, is there a single command to change the type?
2. Is there anyway to limit the decimal place to only one?
56.3, 34.2... are acceptable, but 23.112, 77.34, ... are
