Question

Rake 0.8.7
Rails 2.3.18
RubyGems 1.7.2

我查看了类似的问题，但这里不适用：

在任务中没有进行任何递归
不使用Bundler或RVM（如果使用bundler是解决方案，那么我就搞砸了）
不包括ActionView :: Helpers
未使用名为scrubyt的宝石
更改代码以使用事务无法解决问题。

Braindead简单行更新。如果我将其作为迁移或种子运行，结果相同。

class AddValuesForPlanApiQuotaDaily < ActiveRecord::Migration
  def self.up

    p = Plan.find(10)
    p.api_quota_daily = 3000
    p.save!

  end
end

或者来自db / seeds.rb：

p = Plan.find(10)

if p.api_quota_daily.nil?

    p.api_quota_daily = 3000
    p.save!

end

结果：

$ rake db:seed --trace
** Invoke db:seed (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:seed
rake aborted!
stack level too deep

无法升级rake或开始为此项目使用bundler。

Answer 1

另一个实际上是单词的选项，在迁移中使用原始SQL执行：

class AddValuesToPlanApiQuotas < ActiveRecord::Migration
  def self.up
  plan_id_api_limits = {
      10 => 3000,
      20 => 3000,
      30 => 5000,
      40 => 10000,
      50 => 20000,
      60 => 35000
    }
    plan_id_api_limits.each do |k,v|
      query = "UPDATE plans set api_quota_daily = #{v} where id=#{k}"
      ActiveRecord::Base.connection.execute(query);
    end
  end

end

我显然无法在0.8.7的rake迁移或种子任务中使用ActiveRecord。

Answer 2

不幸的是，我无法从经验中说出来，但我想知道这篇博客的内容是否可以帮到你：

http://dalibornasevic.com/posts/5-ruby-stack-level-too-deep-systemstackerror

基本上：

ulimit -a | grep 'stack size'

和

ulimit -s <some reasonably larger number>

希望有所帮助。

当然，我假设你是在类Unix系统上这样做的。

Answer 3

这是一种可怕的做法，但我没有时间完成这项任务，今天也无法用耙子研究问题。

ruby script/runner db/seeds.rb

Ta da。

rake 0.8.7 db：migrate或db：种子运行时错误，＆＃34;堆栈级别太深＆＃34;
