geokit-rails的未定义方法'merge_conditions'

Question

我正在玩Geokit-Rails(https://github.com/andre/geokit-rails),我需要查找距离原点10英里范围内的所有记录.这是我的错误:

Company.find(:all, :origin=>'New York, NY', :within=>10)
NoMethodError: undefined method `merge_conditions' for #<Class:0x0000010832f740>

from script/rails:6:in `<main>'

我acts_as_mappable在Company.rb,我已经迁移列lat和lng成公司.我哪里错了？

我自己偶然发现了这件事.

这完全是一个1分钟的黑客修复,但由于它是一个相对无害的方法插入,不会影响它的使用范围,我只是将方法直接添加到插件中.

merge_conditions是rails 2.3.8中不推荐使用的 ActiveRecord :: Base方法.

插入app/vendor/plugins/geokit-rails/lib/geokit-rails/acts_as_mappable.rb

  private
    def merge_conditions(*conditions)
    segments = []

    conditions.each do |condition|
      unless condition.blank?
        sql = sanitize_sql(condition)
        segments << sql unless sql.blank?
      end
    end

    "(#{segments.join(') AND (')})" unless segments.empty?
    end

我不确定是什么替换了这种手动SQL条件链接(可能是:范围？),所以geokit代码有点旧,但有时你需要1分钟的黑客修复,特别是当黑客被包含在内时较旧的外部图书馆......

我想我会发现原始代码是否在其他地方调用merge_conditions.也许我会花时间找出更新代码的"正确"方法,如果它仍在积极管理中.

我们不是唯一遇到这个问题的人.

必须像第一条评论一样尝试myModel.geo_scope,bblzzz ......
