问题 I have a full operating locale django app, but I'm having troubles while migrating to the site5 server.

Any idea? 回答1: http:/

问题 This is my first real crack at making a database in Third Normal Form. I managed to create the DDL script ok (I had the logical model verified to 3NF before I went ahead and built the script) but I get a whole lot of errors I am unsure of fixing. I may have bitten more than I can chew for this particular case but I don't want to give up - it's a big learning curve for me and with some help I can get past this and move on. First of all, here is my DDL script: -- This sql script creates the
