我有一個共享引擎,我保持共享AR模型和一堆其他東西。 下面是我的用戶AR模型從Rails引擎模型繼承時的關聯問題
module Shared
class User < ApplicationRecord
validates_presence_of :password, on: :create
# validates_uniqueness_of :email
# validates_uniqueness_of :phone_number
has_many :apps
end
end
而且我在主樑的應用程序(Analytics
)兒童用戶,如下所示:
class User < Shared::User
self.table_name = 'users'
end
當我安裝這臺發動機的Rails應用程序,我動態用下面的方法找到的「正確」(Analytics::User
):
def model_const(const)
# shell_app is set to 'Analytics' somewhere else
shell_app.constantize.const_get const
rescue
Shared.const_get const
end
通過上面,我可以插入,找到數據庫中的記錄,但是當我使用assoc命令的問題開始和儀器選型的AR驗證(以上validates_uniqueness_of
呼籲實例)
user = model_const('User').create ... # works, returns a Analytics::User instance
user.apps # fails with below error
(同樣的錯誤,如果在共享::用戶模式,我未評論驗證,並嘗試建立一個新的記錄)
ActiveRecord::StatementInvalid (PG::UndefinedTable: ERROR: relation "shared_apps" does not exist
LINE 8: WHERE a.attrelid = '"shared_apps"'::regclas...
^
: SELECT a.attname, format_type(a.atttypid, a.atttypmod),
pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod,
(SELECT c.collname FROM pg_collation c, pg_type t
WHERE c.oid = a.attcollation AND t.oid = a.atttypid AND a.attcollation <> t.typcollation),
col_description(a.attrelid, a.attnum) AS comment
FROM pg_attribute a LEFT JOIN pg_attrdef d
ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"shared_apps"'::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
):
而且請注意,我正在創建並嘗試在共享引擎代碼中訪問apps
,不確定是否重要。
在此先感謝!
