i want delete element hash in rails. delete method looks promising, , works 1 unintended consequence... deletes model. # users. @search = user.all # unset yourself. id stored in current_user.id @users.delete(current_user.id) the resulting @users hash in fact have own id removed... deletes model. correct way unset key in ruby / rails? the behaviour describe isn't accurate on many counts. first, user.all returns array, not hash, assuming you're using activerecord here, premise of question flawed. secondly, deleting item array using array#delete not invoke delete on item itself. isn't true. wouldn't hash either. thirdly, also won't delete item array @ all, unless index happens match index of item in array, isn't likely. you're wildly misinterpreting experiment. you don't delete things array passing field belonging object (like id) array#delete . need pass array index. need figure out index of record matching current user, ,

i wondering benefit of passing parameters class rather method. in terms of code, what's benefit of doing this: $books = new books($book_id, $book_name); instead of $books = new books; $books->setbook($book_id, $book_name); thanks! "passing class" not thing. new foo($bar, $baz) instantiating new object , passing parameters constructor method : class foo { public function __construct($bar, $baz) { ... } } there's no difference such between passing parameters regular method , constructor. difference constructor called when object instantiated, , other methods called anytime later. you should pass parameters constructor object requires @ construction time. typically means pass parameters required object work @ all. constructor can throw exception if doesn't parameters, means object fail instantiate @ all. guarantees object in known, consistent state. compare: $api = new fooapi($id, $password); $api->dosomething()

[[[[],3],2],1] i can't understand how can make return flattened list [3, 2, 1] . possible @ all? in syntax [h|t], h element , t list (at least proplist), in code [reverse(t) | [h]] creates list first element result of reverse(t) , , tail single element list [h] . if want achieve function way, should use syntax proposed fenollp. if want write efficient code, should avoid make multiple intermediate copy of partial results, , avoid non tail recursive calls (in order limit size of call stack: reverse(l) -> reverse(l,[]). % use accumulator create tail recursive function reverse([],r) -> r; reverse([h|t],r) -> reverse(t,[h|r]). % [h|r] can evaluated before recursively calling reverse

here pseudo code : [[[@[ctx1,ctx2]rac_sequence]signalwithscheduler:racscheduler.immediatescheduler] flattenmap:^racstream *(id ctx) { // first flatten map return [racsignal createsignal:^(id <racsubscriber> subscriber) { [executerequestasynch ondone:^{ [subscriber sendnext:ctx]; [subscriber sendcompleted]; } ] }] flattenmap:^racstream *(id ctx) { // second flattenmap }]; } now here want happen upon subscribe: 1) ctx1 should fed first flattenmap block 2) server request "executerequestasynch" should called 3) on completion of serverrequest second flattenmap should called ctx1 4) ctx2 should fed first flattenmap block 5) server request "executerequestasynch" should called 6) on completion of serverrequest second flattenmap should called ctx1 but instead scenario happens: 1) ctx1 gets fed first flattenmap block 2) server request "executerequest

i'm building project on top of existing code written developer. it's javascript project build chrome extension. 1 of html files has code written in following format: <% $.each(this, function(index, value) { %> <% var valpart = value.from_mail.split('<'); %> <% var name = valpart[0]; %> <% var ma_name= name; %> and of html tags on page contain elements like <a class='view_name' title='<%= value.filename %>' href='<%= getviewurl(value.viewurl) %>'><%= value.filename %></a> getviewurl function defined in code. main query code between <%...%> now, have fair idea embedded ruby html files use <% ... %> creating code elements inside html file. know fact ruby isn't being used in project or erb files matter. idea be? looks underscore template: http://underscorejs.org/#template

i have dataset records have 2 variables: "time" id's of decades, , "latitude" geographic latitudes. have 7 time periods (numbered 26 32). i want visualize potential shift in latitude through time. need ggplot2 do, plot graph latitude on x-axis , count of records @ latitude on y-axis. need seperate time periods , plot in 1 graph. i understood need function freqpoly ggplot2, , got far: qplot(latitude, data = lat_data, geom = "freqpoly", binwidth = 0.25) this gives me correct graph of data, ignoring time. how can implement time? tried subsetting data, can't figure out if best way.. so i'm trying graph 7 lines showing frequency distribution in each decade in order latitude shift. thanks!! without sample data hard answer try add color=factor(time) (where time name of column time periods). draw lines each time period in different color. qplot(latitude, data = lat_data, geom = "freqpoly", binwidth = 0.25,
