Rails, collection_select - remembering values with :selected after form submitted -

-

(using rails 2.3.5 on internal work server no choice of versions, , i'm pretty new)

i'm building search form need provide list of directories user can select one(s) search against. i'm trying figure out how selected values of collection_select remain after form submitted.

say user selected 3 directories collection_select, id's of directories in params:

directory: !map:hashwithindifferentaccess    id:    - "2"   - "4"   - "6"

i know can manually specify multiple selected items:

<%= collection_select :directory, :id, @directories, :id, :name,                  {:selected => [2,4,6]}, {:size => 5, :multiple => true} %>

i've played around bit , able "to_i" against single value in params hash:

<%= collection_select :directory, :id, @directories, :id, :name,                  {:selected => params[:directory][:id][0].to_i}, {:size => 5, :multiple => true} %>

what can't figure out how use of values of :directory params @ same time user selected remains after form submitted. help.

i'm not precisely sure you're asking, if you're trying array of strings in params[:directory][:id] array of integers, need is

params[:directory][:id].map{|id|id.to_i}

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
