Constants

VERSION

Attributes

query_context[W]

Optional configuration: Set a proc which takes as arguments (1) the class we are counting and (2) the block that runs the count query. The `query_context` block must call the block that's passed as an argument.

This is useful for replication, e.g.,

CachedCounts.query_context = proc do |klass, &run_query|
  role = klass == User ? :reading : :writing
  ActiveRecord::Base.connected_to(role: role) do
    run_query.call
  end
end
