Devise with existing database: 401 Unauthorized us

问题:

I am trying to use devise for user authentication of my website. It uses an existing User table.

The table has username and password, however when I try to log in, I get the following error:

Completed 401 Unauthorized in 90ms.

Logs:

回答1:

Its solved! I changed the encryption key of the rails project in configs/initializers/devise.rb.

Rails version: 3.2.13 Devise version: 2.04

I just had this exact problem but only in production (using rails 4 and devise 3).

The solution was to add a domain declaration to the config/initializers/session_store.rb file like this:

YourAppName::Application.config.session_store :cookie_store, key: '_your_session', domain: {
  production: 'prpoduction_domain',
  development: 'development_domain'
}.fetch(Rails.env.to_sym, :all)

Though it is important that this was changed initially due to adding sub-domains to the application.
