i have model person has many comments how sort people collection number of comments something person.desc(:"comments.count") you can't work 2 collections @ once need in person can can sort on. usual approach use counter cache cache number of comments in each person . you'd have this: class person include mongoid::document has_many :comments end class comment include mongoid::document belongs_to :person, :counter_cache => true end the :counter_cache => true option belongs_to add comments_count field person contain cached number of comments. once have counter cache, can say: person.desc('comments_count') to sorting. you'll need initialize counters hand using person.reset_counters or person#reset_counters things started.

i'd read large file line line, perform string replacement , save changes file, iow rewriting 1 line @ time. there simple solution in php/ unix? easiest way came on mind write lines new file , replace old one, it's not elegant. i think there're 2 option use memory read, replace store replaced string memory, once done, overwrite source file. use tmp file read & replace string write every line tmp file, once done, replace original file tmp file the #1 more effective bcuz io expensive, use if have vast memory or processing file not big. the #2 bit slow quite stable on large file. of course, may combine both way writing replaced string by chunk of lines file (instead of by line ) there're simplest, elegant ways can think out. please correct me if wrong.
