ruby on rails - How to send form data to #index with post instead of #create? -

-
i have resource route setup: resources :events for 1 form, i'd send data #index action :post method. how can this? i tried <%= form_tag url_for(controller: 'events', action: 'index'), method: :post , still goes #create short answer: can't routes. long answer: when using resources :events following routes defined you: get /events events#index /events/new events#new post /events events#create /events/:id events#show /events/:id/edit events#edit patch/put /events/:id events#update delete /events/:id events#destroy therefore index action isn't accessible post request. and trying (with f.e. custom routes resources :events ) make create action on post inaccessible.

i'm rather asking if makes sense this. have not seen examples of haven't seen goes against idea. i in publisher-subscriber model, idea have far is: create list of topics, added file. but instead of having each name of topic , pointer next topic, kind of wanted have node of suscribers each topic, in each topic's node. since i'm explaining myself poorly, idea: struct topicnode{ char * topicname; //i believe there no problem pointers in lists again, have not seen doing either so... struct suscribernode; struct topicnode next; }; and make, if there's suscriber topic, list of suscribers topic. i've done similar things in java, i'm worried it's not such idea in c. yes, single linked list can contain data ------------------------------ ------------------------------ | | | \ | | | | data | next |--------------| data | next | |

we migrating microsoft's analysis services (ssas) hp vertica database our olap solution. part of involves changing our query language mdx sql. had custom mdx query generator allowed others query data through api or user interface specifying needed dimensions , facts (outputs). generated mdx queries ok , didn't have handle joins manually. however, using sql language , since keeping data in different fact tables need find way how generate queries using same dimension , fact primitives. eg. if user wants see client name number of sales, might take request: dimensions: { 'client_name' } facts: { 'total_number_of_sales' } and generate query this: select clients.name, sum(sales.total) clients join sales on clients.id = sales.client_id group 1 and gets more complicated quickly. i thinking graph based solution store relations between dimension , fact tables , build required joins finding shortest path between nodes in graph. i appreciate information

Image
i working on mac app. wandering if possible change title bar colour in nswindow? know how remove it, problem removes 3 buttons (close, minimise, resize). want keep 3 buttons rid of bar. is there anyway this? yes, it's been done here on so: how change color of nswindow title bar in osx they one-link answers bad form here, heck-- you're asking. , works-- i've tried myself. the couple things notice: code there works on default window of nsapp... need bit of work generalize case of / "any" nswindow. ( take code puts in appdelegate , move own subclass of nswindow or nswindowcontroller. controller. ) also, says subclass nsview "mytitleview", in code, it's called "blacktitlebarview"... pick 1 name, consistent, , it's fine. also, color of title text in drawstring: method, has [nscolor whitecolor]. also, gets fancy gradients, you'll see when run code... if don't need or want that, can replace chunks of code

image processing - Rolling ball background subtraction algorithm for OpenCV -

-
is there opencv (android) implementation of "rolling ball" background subtraction algorithm found in imagej: process->subtract background? opencv has backgroundsubtractormog class, used video streams not single, independent images. this example of method does: http://imgur.com/8sn2cfz here documentation of process: http://imagejdocu.tudor.lu/doku.php?id=gui:process:subtract_background there's no implementation in opencv c libraries know of , android jni wrappers - wrappers around main libraries. having said source code imagej implementation available online here , should able incorporate directly android image processing pipeline. there discussion relative merits of rolling ball vs. e.g. using disk structuring element (which is available in opencv) here . if absolutely require rolling ball , opencv unfortunately it's not available 'out of box'.

multithreading - c# Controlled Thread Pooling. More threads are running simultaneously than expected -

first timer threadpooling , critical sections. i'm trying manage number of threads active @ given time. mythreadpool class manages thread counts , active threads. myusefulwork has square method accessed threads. main method queues work using threadpool.queueuserworkitem. i'm using manualresetevent class methods set() , waitone() try , limit threads max count(mythreadpool.maxthreads) 3 in example. apparently i'm doing wrong, given activethreads count going way beyond maxthreads upto 18(which displayed in output 'increment: number' or 'decreement: number'). activethreads incremented within lock if thread waiting, active thread not incremented. so if can point out doing wrong, of great help. thank you. using system; using system.collections.generic; using system.threading; namespace threadingdemo { class myusefulwork { public void square(object number) { try { console.writeline("thr

How method preference work in java? -

-
i want understand how below code snippet work ? class annathread extends thread { public static void main(string args[]){ thread t = new annathread(); t.start(); } public void run(){ system.out.println("anna here"); } public void start(){ system.out.println("rocky here"); } } output - rocky here there's not explain. you override start() code prints rocky here then call start() prints rocky here . (the run method never involved) people confuse purpose of start , run . see instance question:        why call thread.start() method in turns calls run method? the rules simple: thread.run ordinary method (no magic) thread.start contains magic because spawns separate thread (and lets thread invoke run ). if override thread.start own method, there's no magic left anywhere.

i use toolbar action bar, drawerlayout , actionbardrawertoggle. min , target sdk 21. @ point, working fine while device running 5.0.1 (api 21). other day, got 5.1 update , drawer toggle broke - arrow/hamburger icon not showing more. here code: setactionbar((toolbar) findviewbyid(r.id.toolbar)); drawerlayout = (drawerlayout) findviewbyid(r.id.drawer_layout); drawertoggle = new actionbardrawertoggle(this, drawerlayout, r.string.action_open_drawer, r.string.action_close_drawer); drawerlayout.setdrawerlistener(drawertoggle); i have drawertoggle.syncstate() in onpostcreate(). since i've updated min , target 22, along compile , build tools 22 , 22.0.1 respectively, , support libs use 22.0.0, , nothing helped. any ideas? so managed hamburger/arrow icon work again. did add magic line: getactionbar().setdisplayhomeasupenabled(true); why works have no idea. seems not make sense, hamburger has nothing drawer toggle. or it?
