Hartl Rails教程 - 种子用户密码

Question

I'm working my way through the excellent Rails tutorial by Michael Hartl, and I'm trying to wrap my head around an aspect of the seed users. I just finished chapter 9, so I've got a working login/logout/edit/delete system with admin privileges. As part of this chapter, we create some dummy users in the fixtures file:

michael:
  name: Michael Example
  email: michael@example.com
  password_digest: <%= User.digest('password') %>
  admin: true

My question is: how do I login as michael@example.com? It's not clear to me what the password is. On a related note, what is the best practice for creating a universal "admin" user? Should I use a fixture, or should I add one to the database through the Rails console before deploying the app?

Thanks for your help!

Answer 1

You're generating password digest from string "password"

User.digest('password')

So user's password is "password"

Answer 2

The password is not saved as-is in the database. Instead a digest/secured version of the same is saved. The method #digest takes a parameter and outputs the digest version.

So, technically, the set password is "password". But in the database, you'll find it gibberish.

Makes sense?

Answer 3

To address the main question what is database seed. db/seed.rb is a very nifty thing that helps you to seed some test users really fast. As you can see it has the .rb extension so it is a normal ruby program nothing unusual. You have access here to all your Models and don't have to enter everything manually from console. Well I guess what's the deal with password you already figured out form the previous answers. Just take a look at the method digest, and on SitePoint is the perfect article about how user should be authenticated. And for your final question take a look at this article , it will help you understand the concept
