optimization - Saving result of has_one association to avoid fetching DB in Rails? -

-

i have has_one association between user model , player model. see myself doing current_user.player many times in controllers , views, , feel hitting db way every time that. nice have current_player method.

how , define method can access current_player both controllers , views?

it's (properly) going reload @ least once each time hit page, can prevent following loads memoizing result:

class user   has_one :player   def current_player     @current_player ||= player   end end

as alternative, possibly include player model in default scope, loads whenever user model loaded:

class user   has_one :player   default_scope includes(:player) end

unfortunately, whenever i've tried tend find didn't want auto-loading other table every time, , switch previous method loads 2nd table on first use. memoizing object ivar vastly more flexible.

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
