Rails 审核批量创建

Question

我使用 rails 5 / 审核 4.6.5 我一次对 2000 多个项目进行了批量操作。为了使其可用，我需要使用 updatre_all 函数。

那么，我想一次性创建需要的audited

我想做的是这样的事情：

Followup.where(id: ids).in_batches(of: 500) do |group|
  #quick update for user responsiveness
  group.update_all(step_id: 1)
  group.delay.newAudits(step_id: 1)
end

但经过审核的 gem 看起来很基础。我敢肯定很多人以前都遇到过这样的问题

Answer 1

在 group.update_all 中，您的回调将被跳过，并且不会最终记录新审计中的更改。

您不能为这些记录手动创建审核，即使您可以手动创建审核更改，您也需要 "what changed?" 的参考（进入 audited_changes）。但是当您之前在 group 上执行 update_all 时，这些更改已经丢失。

(`action`, `audited_changes`, `auditable_id`, `auditable_type`, `created_at`, `version`, `request_uuid`)

在这个audited issue - https://github.com/collectiveidea/audited/issues/352

中也有记载

paper_trail, another such gem which retains change_logs, also has this issue: https://github.com/airblade/paper_trail/issues/337

Answer 2

经过多次迭代，我设法创建了一个优化查询。我把它放在 AditBatch class 中，还添加了延迟

class AuditBatch


############################################
## Init a batch update from a list of ids
## the aim is to avoid instantiations in controllers
## @param string class name (eq: 'Followup')
## @param int[] ids of object to update
## @param changet hash of changes {key1: newval, key2: newval}
############################################

def self.init_batch_creation(auditable_type, auditable_ids, changes)
    obj = Object.const_get(auditable_type)
    group = obj.where(id: auditable_ids)
    AuditBatch.delay.batch_creation(group, changes, false)
end

############################################
## insert a long list of audits in one time
## @param group array array of auditable objects
## @param changet hash of changes {key1: newval, key2: newval}
############################################
 def self.batch_creation(group, changes, delayed = true)

  sql = 'INSERT INTO audits ("action", "audited_changes", "auditable_id", "auditable_type", "created_at", "version", "request_uuid") 
  VALUES '

  total = group.size
  group.each_with_index  do |g, index|

    parameters = 'json_build_object('
    length = changes.size
    i=1
    changes.each do |key, val|
      parameters += "'#{key}',"
      parameters += "json_build_array("
      parameters += "(SELECT ((audited_changes -> '#{key}')::json->>1) FROM audits WHERE auditable_id = #{g.id} order by id desc limit 1),"
      parameters += val.is_a?(String) ? "'#{val.to_s}'" : val.to_s 
      parameters += ')'
      parameters += ',' if i < length
      i +=1
    end
    parameters += ')'

    sql += "('update', #{parameters}, #{g.id}, '#{g.class.name}', '#{Time.now}', (SELECT max(version) FROM audits where auditable_id= #{g.id})+1, '#{SecureRandom.uuid}')"
    sql += ", " if (index+1) < total
  end
  if delayed==true
    AuditBatch.delay.execute_delayed_sql(sql)
  else
    ActiveRecord::Base.connection.execute(sql)
 end

 end

def self.execute_delayed_sql(sql)
  ActiveRecord::Base.connection.execute(sql)
end
end
