优点宝石能否重新评估声誉并重新评估徽章和等级？ [英] Can the merit gem recalculate reputation and re-evaluate badges and ranks?

问题描述

我想在我的Rails应用程序中添加点数，排名和徽章系统。 merit 宝石看起来很酷，但我想确保在使用它之前它是如何工作的。

定义徽章

 ＃app / models / merit / badge_rules.rb 
 grant_on'comments＃vote'，：badge = > 'relevant-commenter'，：to => ：用户do | comment | 
 comment.votes.count == 5 
结束
  

和分数

 ＃app / models / merit / point_rules.rb 
得分10，：to => ：post_creator，：on => '评论＃创建'do | comment | 
 comment.title.present？ 
 end 
  

表明动作是作为一个钩子完成的， code> comments＃vote 或 comments＃create ）。我没有看到徽章和积分的计算/归属如何工作，所以我不确定。

由于我的应用会随着时间的推移而发展，所以我希望成为能够改变点和徽章规则并重新评估它们。例如：假设我首先决定授予帐户激活10分。我希望能够将其更改为20，然后重新评估所有激活的配置文件并获得+10点增加。同样的事情徽章。

这个宝石是否支持？

解决方案

有可能在具有优点的应用程序中重新计算声誉。优点保持在 Merit :: Action 模型中映射到 merit_actions 的哪个点/徽章授予哪个动作的历史记录> table。

以下脚本应该可以工作（首先备份，因为我还没有在生产环境中这样做）：

 ＃1.重设所有徽章/得分
优点:: BadgesSash.delete_all 
优点::得分:: Point.delete_all 
 
＃1.1可选择重置活动日志（直到现在授予/移除的徽章/积分）
优点:: ActivityLog.delete_all 
 
＃2.将所有`merit_actions`标记为未处理的
优点:: Action.all.map {| a | a.update_attribute：processed，false} 
 
＃3.重新计算信誉规则
 Merit :: Action.check_unprocessed 
 Merit :: RankRules.new.check_rank_rules

I would like to add a system of points, ranks and badges in my rails app.

The merit gem looks cool, but I want to make sure how it works before using it.

The way you define badges

# app/models/merit/badge_rules.rb
grant_on 'comments#vote', :badge => 'relevant-commenter', :to => :user do |comment|
  comment.votes.count == 5
end

and points

# app/models/merit/point_rules.rb
score 10, :to => :post_creator, :on => 'comments#create' do |comment|
  comment.title.present?
end

suggest that the action is done as a hook, just after the action (comments#vote or comments#create) in those cases. I havn't looked how the calculation/attribution of badges and points work yet so I am not sure.

As my app will evolve over time, I would like to be able to change the point and badges rules and re-evaluate them. Eg: Say I first decide to grant 10 points on account activation. I would like to be able to change it to 20 and then all activated profiles are re-evaluated and get a +10 point increase. Same thing for badges.

Does this gem support that ?

解决方案

It is possible to recompute reputation in an app with merit gem. Merit keeps the history of which actions triggered which point/badge granting in Merit::Action model, which is mapped to merit_actions table.

Following script should work (do a back up first, as I didn't do this in production yet):

# 1. Reset all badges/points granting
Merit::BadgesSash.delete_all
Merit::Score::Point.delete_all

# 1.1 Optionally reset activity log (badges/points granted/removed until now)
Merit::ActivityLog.delete_all

# 2. Mark all `merit_actions` as unprocessed
Merit::Action.all.map{|a| a.update_attribute :processed, false }

# 3. Recompute reputation rules
Merit::Action.check_unprocessed
Merit::RankRules.new.check_rank_rules
