I ask because I would like to use Spring to preload my fixtures prior to forking. (It’s taking about 6 seconds to load ~300 fixture files)
However, after forking, ActiveRecord::Base returns a new connection (probably because one needs to establish a new connection after forking). This meant that FixtureSet.cache_for_connection returned nil even though there is a class level fixture cache.
The following monkey-patch gives me the cached fixtures again.
-
ActiveRecord::FixtureSet.class_eval do
-
# spring reconnects - this results in a new ActiveRecord::Base.connection object -
def self.cache_for_connection(connection) -
ActiveRecord::FixtureSet.class_variable_get(:@@all_cached_fixtures).values.only -
end -
end

Could it be for multiple databases or something like multi-threading ?
