我正在尝试从 Member.board.order 的模型 Members 升序排序
在我的 Controller 上，institutional_controller.rb 我有:
@display = Member.includes(:board).where('is_board = ?', true).order('member.board.order ASC').references(:board)
# board.rb and member.rb
class Board < ActiveRecord::Base
belongs_to :member
end
class Member < ActiveRecord::Base
has_one :board
end
# index.html.erb
<% @display.each do |member| %> [...]
我得到的错误是:
PG::UndefinedTable: ERROR: missing FROM-clause entry for table "board"
LINE 1: ...= "members"."id" WHERE (is_board = 't') ORDER BY member.board [...]
谢谢。任何帮助将不胜感激。
最佳答案
现在它是这样工作的:
Member.includes(:board).where('is_board = ?', true).order('boards.order ASC').references(:board)
