我正在尝试在我的帐户模型中定义范围,但它无效。这是我的代码:
class Account < ActiveRecord::Base
has_many :organizations
scope :primary, joins(:organizations).where('organizations.primary = ?', true)
accepts_nested_attributes_for :organizations
end
class Organization < ActiveRecord::Base
belongs_to :account
has_many :locations
accepts_nested_attributes_for :locations
end
在控制台中,我尝试了以下命令:
Account.primary.first
但是我收到以下错误:
ActiveRecord::StatementInvalid: SQLLite3::SQLException: near "primary":
syntax error: SELECT "accounts".* FROM "accounts" INNER JOIN "organizations" ON
"organizations"."account_id" = "accounts"."id" WHERE (organizations.primary = 't')
LIMIT 1
我认为“主要”这个名称可能会导致问题。当我将范围重命名为“重要”并尝试我得到:
NoMethodError: undefined method 'important' for #<Class:0x1f4a900>
如果有人可以提供帮助,我会非常感激。

我认为您的问题是您有一个名为“primary”的列,而且是reserved word。试着引用它:
scope :primary, joins(:organizations).where('organizations."primary" = ?', true)
此例外:
SQLLite3 :: SQLException:靠近“primary”:
来自SQLite,而不是来自ActiveRecord或Rails。
