Hi Sundar
Sorry for being so slow on responding to this.
Certainly, the code you’ve got there will not remove documents from the core
index. What this means is that any queries that match old data in the core
index will return results that you may not want. What you could do instead is
the following:
ids = Article.where(<some_condition>).pluck :id
Article.where(:ids => ids).update_all :delta => true
ThinkingSphinx::Deltas::IndexJob.new(‘article_delta’).perform
indices =
ThinkingSphinx::Configuration.instance.indices_for_references(:article)
indices.reject { |index| index.delta? }.each do |index|
ids.each do |id|
ThinkingSphinx::Deltas::DeleteJob.new(
index.name, index.document_id_for_key(id)
).perform
end
end
Note that this code should work with TS v3.0.4. A slightly simpler approach
(which involves far fewer Sphinx queries) is available since v3.1.2:
ids = Article.where(<some_condition>).pluck :id
Article.where(:ids => ids).update_all :delta => true
ThinkingSphinx::Deltas::IndexJob.new(‘article_delta’).perform
indices =
ThinkingSphinx::Configuration.instance.indices_for_references(:article)
indices.reject { |index| index.delta? }.each do |index|
ThinkingSphinx::Deletion.perform index, ids
end
If you wanted to push this behaviour into Delayed Job instead, then I’d
recommend creating a custom job class to do so (as the internals of
ts-delayed-delta for deleting from the core index are written with single
instances in mind).
Hope this helps!
