Rails 3-数据库种子数据验证 [英] Rails 3 - DB seed data validation

问题描述

我正在通过seeds.rb文件中的数千个create调用在Rails 3.1中植入测试数据库.

I am seeding a test database in Rails 3.1 through thousands of create calls in the seeds.rb file.

当这些调用未通过模型验证时会出现一个小问题:rails不会通知我这一点，并且播种会正确进行直到文件结束.在该过程的最后，我不知道哪些记录已经创建，哪些记录没有创建，除非我逐一检查它们...

A little problem arises when these calls do not pass the model validations: rails will not notify me this, and the seeding goes on correctly until the end of the file. At the end of the process I do not know which records have been created and which aren't, unless I check them one by one ...

当使用rake db:seed或rake db:reset的记录未通过验证时，是否有办法得到通知?

Is there a way to get notified when records do not pass validations when using rake db:seed or rake db:reset?

谢谢！

推荐答案

您可以在模型中创建所需的验证，然后使用ModelName.create!.如果输入无效，则会引发异常

You can create validations you want in the Models and use ModelName.create!. This will raise an exception if the input is invalid
