in cakephp each method of controller has own view , view template file name of method. class datacontroller extends appcontroller { public function one() { // render one.ctp } public function two() { // render two.ctp } } accourding api documentation there $view property of controller specifies view render. should have ability specify default view file, all.ctp , methods of controller class datacontroller extends appcontroller { public $view = 'all'; public function one() { // should render all.ctp } public function two() { // should render all.ctp } } however not work , cakephp ignores $view property , continues template file of same name method. is there way have default view without having insert $this->render('all'); in each of controller's methods? the value going overridden in controller::setrequest() being called in controllers class constructor . you use controllers beforefilter()

how subscribe objects being added , removed nsmutabledictionary using reactivecocoa? also, i'd broadcast notification when changes. guess broadcasting can done using racmulticastconnection how tie dictionary change? i'm trying use reactivecocoa first time in project , stuck on first thing wanted :( racobserve wrapper around key-value observing , , inherits same features , flaws. unfortunately, nsmutabledictionary not automatically observable. there 2 ways work around that: subclass , add kvo support . create real model object, properties instead of dictionary keys. you'll kvo on properties, long use setters instead of direct ivar modification. i'm not sure mean "[broadcasting] notification when changes," or why it'd valuable. notifications way global taste, , i'd promote using more limited observation instead (like kvo). however, assuming want this, it's simple enough post notification in response new signal value: @weak

clientsitea.com, clientsiteb.com, ....

i'd use matplotlib plot histogram on data that's been pre-counted. example, have raw data data = [1, 2, 2, 3, 4, 5, 5, 5, 5, 6, 10] given data, can use pylab.hist(data, bins=[...]) to plot histogram. in case, data has been pre-counted , represented dictionary: counted_data = {1: 1, 2: 2, 3: 1, 4: 1, 5: 4, 6: 1, 10: 1} ideally, i'd pass pre-counted data histogram function lets me control bin widths, plot range, etc, if had passed raw data. workaround, i'm expanding counts raw data: data = list(chain.from_iterable(repeat(value, count) (value, count) in counted_data.iteritems())) this inefficient when counted_data contains counts millions of data points. is there easier way use matplotlib produce histogram pre-counted data? alternatively, if it's easiest bar-plot data that's been pre-binned, there convenience method "roll-up" per-item counts binned counts? you can use weights keyword argument np.histgram (whic

i have followed tutorial http://www.yiiframework.com/doc/guide/1.1/en/form.table tabular input got stuck. everything works fine except filling inputs. when fill fields , do $model->attributes=$_post['racingtable']; it doesn't pick of entries , when user doesn't fill , suppose show error remove entries inputs. but when this $model->attributes=$_post['racingtable'][0]; it takes entries first group of input fields , fill other groups entries. i'm not talking saving database. i'm talking when user wrong takes him create action , should fill inputs user's entries. post complete controller/action code can better picture. now, guessing not validating model before trying save. , tabular input array hence not able value doing $_post['racingtable']; have define index of array too. that's reason when defining index [0] in second line of code it's taking first set of values. should run loop , try values defining

my understanding of how stuff works limited, make library calls make audio / video magically show up. i want able mitm "attacks" programs on own computer. (i'd guy intercepting signals between software , hardware). kind of thing useful in number or scenarios. for instance, audio: xp doesn't have way change audio specific programs while keeping others unchange. has 1 audio manager across programs. if intercept signal (and detect program coming from) in theory make own audio manager. i record conversations, possibly testing out audio -> text software may have/create. many more. for video: (primary goal here): record conversations. have used third party program, i'm guessing doing taking snapshots because 1) video choppy , 2) when mouse or other thing gets in way of video, records too. wouldn't easier record signal going video card specific program of interest, play when want see again? for network traffic: for recording traffic

i have table orders fields id , customer_id , amt : sql fiddle and want customer_id largest amt , value of amt . i made query: select customer_id, max(amt) orders; but result of query contained incorrect value of customer_id . then built such query: select customer_id, max(amt) maximum orders group customer_id order maximum desc limit 1; and got correct result. but not understand why first query not worked properly . what doing wrong? and possible change second query obtain necessary information me in simpler , competent way? mysql allow leave group by off of query, returning max(amt) in entire table arbitrary customer_id . other rdbms require group by clause when using aggregate. i don't see wrong 2nd query -- there other ways it, yours work fine.
