i searching through array of hashes , need find specific objects within hash. issue getting need search model. searching this... @insur_transactions = user.transactions.find_all { |t| (t.fetch('name').downcase! =~ /user.bill.name/) } the problem wont search hashes object found in bill.name. how pull object bill model , search specific item? using mongoid db. got answer. since using regex can pull object using /#{ object }/ code looks this @insur_transactions = user.transactions.find_all { |t| (t.fetch('name').downcase! =~ /#{user.bill.name}/) } that got it!

i have data in following format \a,b,c,d/ a,b strings of letters , numbers; c, d integers. i tried using format \%s,%s,%d,%d/ format scan it, causes a,b,c,d/ scanf'ed first string instead of a. question: is there type in format in order achieve desired result? you can use following format string use commas delimiters : "\\%[^,],%[^,],%d,%d/" the idea tell scanf read isn't comma each string, read delimiting comma , continue. here (bad , unsafe!) example: char a[100], b[100]; int c=0, d=0; scanf("\\%[^','],%[^','],%d,%d/", a, b, &c, &d); printf("%s, %s, %d, %d\n", a, b, c, d); in real code, you'll want write safer. can example use fgets read full line of input reuse same format string sscanf parse it.

i trying create plot of user login behavior 2 month period. used qplot function ggplot2 package, , following code qplot(date_time, login_count, data=client_login_clean) i plotted login_count on time shown below. unfortunately, y-axis, num_records sorted such first 5 tick marks on y-axis 1, 10, 106, 11, , 12, rather 1, 2, 3, 4, 5. let me know how fix this? that's because, reason, login_count variable character vector. ggplot internally coerces character vectors factors, labels ordered alphabetically, , sorts axis according order. i think know why happened: "num_records" value in login_count column, whole thing has been coerced character vector. delete element , use as.numeric , ordering should correct. opportunity read on data loading/generating process , make sure haven't made other mistakes. tiniest bugs can uncover massive problems never have noticed otherwise. as side note, why should careful character -class variables , ggplot plotti...
