paginate :per_page => per_page, :page => page,
         :include => [{:stores => :locations}, :categories, :kosher], :origin => origin,
         :conditions => ["products.name LIKE ? #{conditions}", "%#{search}%"],
         :within => distance,
         :order => sort_order

我在OSX上使用带有Rails 2.3.5的ruby 1.9.1p243并且此代码工作正常（开发计算机）

在生产服务器上，在Ubuntu上使用Rails 2.3.5的Ruby 1.9.1p376，它会产生SQL错误。

Does anyone have any thoughts on this?

Also, all gems that are used match in version numbers.



Here is the sql that is generated

编辑： 这是因为使用will_paginate插件限制结果。如果我限制结果小于查询返回的结果，它会中断，如果我限制在数字之上，那就没问题。

您可能忘记了在服务器上进行迁移。检查'locations.lat'是否存在。

答案 1 :(得分：1)

我通过将will_paginate信息替换为：offset和：limit。

来修复此问题 
find     :all, :offset => per_page.to_i * (page.to_i - 1), :limit => per_page,
         :include => [{:stores => :locations}, :categories, :kosher], :origin => origin,
         :conditions => ["products.name LIKE ? #{conditions}", "%#{search}%"],
         :within => distance,
         :order => sort_order
