我有一个大型产品数据库（＆gt; 23.000），当我对schema.xml或sunspot的搜索定义进行更改时，我想重新索引所有产品。但有时重新索引失败并出现以下错误：
FloatDomainError: Infinity

我调试了重新索引，并抓住了抛出该错误的产品。但是，当我尝试在该产品上调用.index方法时，一切正常。
我已经读过这个FloatDomainError: Infinity，当支持INFINITY的某个数字数据类型转换为数字数据类型时，会发生这种情况，并且不支持{{1} }。问题是，我无法弄清楚，从哪里开始调试，或究竟是什么导致了这个错误。
修改
我向github repo提交了一个问题：https://github.com/sunspot/sunspot/issues/521
因为它更容易，我也在这里添加来自github的信息：
这是INFINITY字段的搜索定义（该字段会引发错误）：
count_on_hand我不认为integer :count_on_hand, stored: true do |product|
product.on_hand.nil? ? -1 : product.on_hand
end
字段定义很有用，因为它们只包含标准配置。
然后，我调试了太阳黑子宝石内schema.xml的{{1}}方法，并在抛出错误时添加了更多输出：
populate_document如您所见，来自field_factory.rb:57的{{1}}的值为model.inspect =>
#<Spree::Product id: 19502, name: "Foo Bar", description: "Bar foo", available_on: "2013-12-14 13:30:10", deleted_at: nil, permalink: "foo-bar", meta_description: nil, meta_keywords: "", tax_category_id: 3, shipping_category_id: 1, created_at: "2013-11-26 15:12:25", updated_at: "2013-12-14 13:30:10", count_on_hand: 2>
document.inspect =>
#<RSolr::Xml::Document:0x007ff6f4d58390 @fields=[#<RSolr::Xml::Field:0x007ff6f4d58570 @attrs={:name=>:id}, @value="Spree::Product 19502">,
<RSolr::Xml::Field:0x007ff6f4d58b88 @attrs={:name=>:type}, @value="Spree::Product">,

<RSolr::Xml::Field:0x007ff6f47a7220 @attrs={:name=>:price_f}, @value="10.3">],
@attrs={:boost=>1.0}>
@field =>
#<Sunspot::AttributeField:0x00000006081320 @multiple=false, @type=#<Sunspot::Type::IntegerType:0x00000003722dd0>, @name=:count_on_hand, @stored=true, @more_like_this=false, @indexed_name="count_on_hand_is", @reference=nil>
value =>
Infinity
。但是方法中的count_on_hand变量的值为model.inspect。此外，2并未显示在value中。我不确定，如果这与它有关，但也许这是一个暗示。
问题是，我无法在开发中重现这个问题。上面的错误在生产中被抛出，这就是为什么我对太阳黑子宝石进行猴子修补，并将此代码添加到生产中（以及Airbrake.notify）：
