我正在使用此宝石评论:https://github.com/lml/commontator
设置为轻松插入此gem以对评论进行投票:https://github.com/ryanto/acts_as_votable
一切似乎都很好。但是当试图计算用户总票数(用户在所有评论上收到的总票数)时(业力)
<%= @user.votes.count %>
我收到此错误
undefined method `votes' for #<User:0x0000010dbf23a0>
所以我尝试了这个:
<%= @user.comments.map{|c| c.votes.count}.inject(:+) %>
导致了另一个错误:
SQLite3::SQLException: no such column: commontator_comments.commontator_id: SELECT "commontator_comments".* FROM "commontator_comments" WHERE "commontator_comments"."commontator_id" = ? AND "commontator_comments"."commontator_type" = ?
如何呈现特定用户在所有评论中收到的总投票数?
答案 0 :(得分:2)
假设您有此设置
class User < ActiveRecord::Base
acts_as_voter
acts_as_commentator
has_many :comments
end
class Comment < ActiveRecord::Base
acts_as_votable
belongs_to :user
end
安装commentator
和acts_as_votable
宝石后的以下内容
rails generate acts_as_votable:migration
rake commontator:install
rake db:migrate
你应该能够得到像这样的票数
@user.comments.collect{|c| c.votes.size}.inject(:+)
