Ruby on Rails使用预先存在的数据库。 Rails使一切变得复数

Question

What is the deal with this? I'm working with a pre-existing that I did not do myself. Everything in the database is labeled in singular form. user, security, spec, etc. I guess the right way would be users, securities, specs. At least that's what ruby on rails try's to lookup when I generate a scaffold .

How do I specifically state to use user instead of users in the sql. I don't see anywhere in my project where it is looking up the sql. I mean if my model is user you would think it would try to lookup user. Instead of users.

Thanks for any help.

Answer 1

You need set_table_name :name_of_the_table in your model ( source ).

So:

class User < ActiveRecord::Base
  set_table_name :user
end

The reason they use plural for the table and singular for the model is because an instance of the model represents one user, whereas the table contains all the users. It's just to make it more readable and logical.

Answer 2

You can specifiy the table name:
