在 ActiveResource 中设置站点/用户字段 [英] Set site/user fields in ActiveResource

问题描述

我正在构建一个将使用 Highrise CRM gem 访问 Highrise 数据的 sinatra 应用程序.这个 gem 基于 ActiveResource 类.我想为每个请求设置站点、用户字段.我遵循了这里发布的建议 - 在每个用户的基础上设置 Active Resource HTTP 身份验证是否线程安全?.我添加了代码(如下所示)，但出现错误.任何人都可以帮助理解此错误以及如何修复它.

I am building a sinatra app that will use Highrise CRM gem to access Highrise data. This gem is based on ActiveResource class. I want to set site, user fields for every request. I followed suggestion posted here - Is it thread safe to set Active Resource HTTP authentication on a per-user basis?. I add code (shown below) and I get an error. Can anyone help understand this error and how to fix it.

class ActiveResource::Base
  class << self
    %w(site user).each do |attr|               

      define_method(attr) do
        Thread.current["active_resource.#{attr}"]
      end

      define_method("#{attr}=", val) do
        Thread.current["active_resource.#{attr}"] = val
      end
    end
  end
end

和错误:

c:/dev/hgadget/application.rb:18:in `block in singletonclass':
undefined local variable or method `val' for #<Class:ActiveResource::Base> (NameError)
    from c:/dev/hgadget/application.rb:12:in `each'
    from c:/dev/hgadget/application.rb:12:in `singletonclass'

推荐答案

我一直在玩很多在运行时动态设置 site 选项的方法，也是我发现的唯一不会导致竞争条件.

I've been playing a lot with setting site option dynamically during runtime and the only solution I have found which will not lead to race condition.

class Runner
  def self.new(site)
    Class.new(ActiveResource::Base) do
      self.site = site
      self.element_name = 'runner'

      # your methods here
    end.new
  end
end
