| * | HasManyAssociation: moved half of counter cache code to reflectionBogdan Gusiev2015-09-033-70/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation has a lot of utility methods that accept reflection call a lot of methods on it and exit. E.g. has_counter_cache?(reflection) It causes confusion and inability to cache result of the method even through it always returns the same result for the same reflection object. It can be done easier without access to the association context by moving code into reflection itself. e.g. reflection.has_counter_cache? Reflection is less complex object than association so moving code there automatically makes it simplier to understand.
