undefined method database_authenticatable' for #<ActiveRecord::ConnectionAdapters::PostgreSQLAdapter::TableDefinition:0xd715388>
迁移是:
class DeviseCreateUsers < ActiveRecord::Migration
def self.up
create_table(:users) do |t|
t.database_authenticatable :null => false
t.recoverable
t.rememberable
t.trackable
t.timestamps
end
add_index :users, :email, :unique => true
add_index :users, :reset_password_token, :unique => true
end
def self.down
drop_table :users
end
end
如果我没记错的话,设计改变了它生成的迁移风格
create_table(:user) do |t|
t.database_authenticatable
end
to
create_table(:user) do |t|
## Database authenticatable
t.string :email, :null => false, :default => ""
t.string :encrypted_password, :null => false, :default => ""
end
2.0版本之后。
