我有以下三个模型
法官（设计用户）
Judge.column_names
=> ["id", "email", "encrypted_password", "reset_password_token", "reset_password_sent_at", "remember_created_at", "sign_in_count", "current_sign_in_at", "last_sign_in_at", "current_sign_in_ip", "last_sign_in_ip", "created_at", "updated_at", "confirmation_token", "confirmed_at", "confirmation_sent_at", "unconfirmed_email"]
class Judge < ActiveRecord::Base
has_many :votes
end
入口
Entry.column_names
=> ["id", "entrant_id", "title_of_work", "price", "created_at", "updated_at", "media_file_name", "media_content_type", "media_file_size", "media_updated_at", "paid", "height", "width", "type_of_media"]
class Entry < ActiveRecord::Base
belongs_to :entrant
has_many :votes
end
投票
Vote.column_names
=> ["id", "entry_id", "judge_id", "score", "created_at", "updated_at"]
class Vote < ActiveRecord::Base
belongs_to :entry
belongs_to :judge
end
我需要一个执行以下操作的查询
如果我以评委身份登录，请选择一个付费入场的人，该人还没有我已经给予的投票。
我有这个，但它似乎不起作用
Entry.where(:paid => 1).includes(:votes).where.not(votes: { id: nil }).where.not(votes: {judge_id: current_judge.id }).first
我正在尝试创建一个显示可以投票的“条目”的页面。一旦投票，投票表中就会有一条记录，并且永远不会再显示。有很多法官，因此这些规则中的每一个都适用于每位法官。
有没有更好的方法来做到这一点？
