Rails devise 插件已创建一个用户表。我怎样才能添加到它？
我使用 devise Rails 插件创建了以下内容。如何向用户表添加用户名字符串和唯一的 user_id 整数？使用devise时还需要创建users_controller吗？或者说没有必要？
class DeviseCreateUsers < ActiveRecord::Migration
def self.up
create_table(:users) do |t|
t.database_authenticatable :null => false
t.recoverable
t.rememberable
t.trackable
# t.encryptable
# t.confirmable
# t.lockable :lock_strategy => :failed_attempts, :unlock_strategy => :both
# t.token_authenticatable
t.timestamps
end
add_index :users, :email, :unique => true
add_index :users, :reset_password_token, :unique => true
# add_index :users, :confirmation_token, :unique => true
# add_index :users, :unlock_token, :unique => true
# add_index :users, :authentication_token, :unique => true
end
def self.down
drop_table :users
end
end
I created the following with the devise rails plugin. How do I go about adding a username string and unique user_id integer to the users table? Also is it necessary to create a users_controller when using devise? Or is that not necessary?
class DeviseCreateUsers < ActiveRecord::Migration
def self.up
create_table(:users) do |t|
t.database_authenticatable :null => false
t.recoverable
t.rememberable
t.trackable
# t.encryptable
# t.confirmable
# t.lockable :lock_strategy => :failed_attempts, :unlock_strategy => :both
# t.token_authenticatable
t.timestamps
end
add_index :users, :email, :unique => true
add_index :users, :reset_password_token, :unique => true
# add_index :users, :confirmation_token, :unique => true
# add_index :users, :unlock_token, :unique => true
# add_index :users, :authentication_token, :unique => true
end
def self.down
drop_table :users
end
end

要回答你的最后一个问题，不，你不需要创建一个控制器来使用 devise，
尽管如果你想为用户提供索引或显示页面，你可以这样做。在这种情况下，您需要修改 路线一点

Although you could do if you wanted to have an index or show page for your users. In which case you would need to modify your routes a little
