问题 I understand that the fastest way to check if a row exists isn't even to check, but to use an INSERT IGNORE when inserting new data. This is most excellent for my application. However, I need to be able to check if the insert was ignored (or conversely, if the row was actually inserted). I could use a try/catch, but that's not very elegant. Was hoping that someone might have a cleaner and more elegant solution. 回答1: Naturally, a final search after I post the question yields the result. mysql

Okay I recently upgraded from Ubuntu 10.04 to 12.04 Only to be faced by a lot of problems.

Getting peewee to work on elastic beanstalk

梦想的初衷 提交于 2019-12-02 10:48:09
问题 I'm trying to install the peewee package on an elastic beanstalk instance to control a bottle application. I think the problem is with the MySQL-python dependency, but peewee doesn't load either. My requirements file looks like this: bottle==0.11.6 peewee==2.1.1 MySQL-python I also tried MySQL-python as MySQL-python==1.2.4b4 . For a number of reasons which I believe are summed up here, this doesn't work; peewee isn't installed and I get this error message in the log: 2013-05-18 06:57:08,407
