association preloading problems

- first off there are some patches on that look sane to me (and maybe have slipped under the radar because they weren't in their own ticket).
Secondly it has been very rightly pointed out that the include_eager_conditions? and include_eager_order? functions that preloading leans on to decide whether to fallback to the old eager loading code aren't smart enough (specifically they understand, but not `other_table`.`foos`).
It's not as completely straightforward as adding that to the regex (currently /([\.\w]+)\.\w+/) since the change to be made obviously depends on how that particular database quotes table & column names.
Anyone have a smart idea for generating the right regular expression ? perhaps lean on connection.quote_table_name and connection.quote_column_name to generate the right delimiters and then the expression is




Oops, meant to post that to core.
Move along, nothing to see :slight_smile:
