literally always have to look up the meaning of :limit in migrations when it comes to integer values. Here's an overview. Now let's memorise it (oh, this works for MySQL, other databases may work differently): | |
:limit Numeric Type Column Size Max value | |
1 tinyint 1 byte 127 | |
2 smallint 2 bytes 32767 | |
3 mediumint 3 byte 8388607 | |
nil, 4, 11 int(11) 4 byte 2147483647 | |
5..8 bigint 8 byte 9223372036854775807 | |
Note: by default MySQL uses signed integers and Rails has no way (that I know of) to change this behaviour. Subsequently, the max. values noted are for signed integers. |
