ruby on rails - How to generate string value for _id field in mongodb collection? -


i want generate id of newly created object string instead of bson::objectid('59afe79b92caf8948b000005').

i using mongoid of version mongoid (4.0.2) .

is there idgeneration of page https://docs.meteor.com/api/collections.html .

i want create id random string(swpabpucounbrjzoh) work our meteor application.

any suggestion helpful me.

thanks,

if generate @ end , assign _id field in insert query, mongo shall accept _id. if don't specify field name _id mongodb intelligently creates _id field generated algorithm can used sorting purpose in future.

here information how object id generated mongodb. click here

you can self generate _id around 17 character (depends how long need it). before inserting make sure not exists. mongodb indexes keys identified field _id. can click here know more how generate desired key. take hints , develop own code.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
