Rails associations has_many through ban/archive solution?

由 半腔热情 提交于 2019-12-08 06:40:22
问题 I'm new in Rails and am working on a problem. I have two tables: Shoes and Socks A Shoe can have many Socks, but only one active Sock. Other Socks are inactive.

FILESYSTEM vs SQLITE, while storing up-to 10M files

由 ↘锁芯ラ 提交于 2019-12-07 06:25:51
问题 I would like to store up-to 10M files, 2TB storage unit. The only properties which I need restricted to filenames, and their contents (data). The files max-length is 100MB, most of them are less than 1MB.

由 廉价感情. 提交于 2019-12-06 23:43:33
trying to rename internal file within a zip file without having to extract and then re-zip programatically. example. test.zip contains test.txt, i want to change it so that test.zip will contain newtest.txt(test.txt renamed to newtest.txt, contents remain the same) came across this link that works but unfortunately it expects test.txt to exist on the system.
