ruby-on-rails - 使用 Sunspot 从 Solr 索引中排除草稿

Question

我有一个名为 Article 的索引模型，我不希望 solr 索引未发表的文章。

class Article < ActiveRecord::Base
  searchable do
    text :title
    text :body
  end
end

如何指定不是#published 的文章？不应该被索引吗？

Answer 1

一定要索引已发布的状态。

class Article < ActiveRecord::Base
  searchable do
    text :title
    text :body
    boolean :is_published, :using => :published?
  end
end

然后将过滤器添加到您的查询中

Sunspot.search(Article) do |search|
  search.with(:is_published, true)
  # ...
end

Answer 2

如果你想确保未发表的文章永远不会包含在搜索索引中，你可以这样做：

class Article < ActiveRecord::Base
  searchable :if => :published? do
     text :title
     text :body
  end
end

该模型将仅在发布时被索引。

但是，如果您还希望管理员能够搜索文章（包括未发表的文章），我的方法就不那么有趣了。

注意：article.index!无论参数如何，调用都会将实例添加到索引中:if => :method。

Answer 3

A small look into the code base of sunspot_rails reveals a method called maybe_mark_for_auto_indexing which will be added to the models that include solr. You could override that method and set @marked_for_auto_indexing based on your criteria in the specific model. Its monkey patching but can help you solve the problem. The code for ur reference is in lib/sunspot/searchable.rb.
