在Rails 3项目中加载种子数据 [英] Load seed data in Rails 3 Project
问题描述
到目前为止，我一直在使用Fixtures和rake任务来为我的数据库创建一些种子数据.这很好用，但是我突然遇到了奇怪的问题(例如在模型中获得1,2,3 ..的自动生成ID，然后在联接模型中获得错误的ID，使关联根本无法工作).
Till now, i have been using Fixtures, along with a rake task to create some seed data for my database. This worked well, but i suddenly have weird problems(like getting autogen ids of 1,2,3.. in a model and then wrong ids in the join model, making the association not work at all).
因此，我想知道什么是更好的选择.我了解了不同的内容，以及有关播种数据的内容.
Thus, i was wondering what a better alternative is. I've read about different things, as well as the railscast on seeding data.
我的数据并没有真正共享相同的信息.就像必须按原样插入单独的条目.例如，认为我必须插入具有特定能力和技能的1000个用户.这需要一些联接模型和对关联的一些整洁处理，例如fixture.
My data does not really share same pieces of information. It's like separate entries that have to be inserted as they are. For instance, think that i have to insert 1000 users that have particular abilities and skills. This needs some join models and some neat handling of the associations like fixtures do.
那么，有没有比固定装置更好的方法来实现这一目标?
So, is there a better than fixtures way to accomplish that ?
