i've got categories table. each category can have optional parent (defaults 0 if no parent). what want build simple html list tree levels of categories. example date: foods -- fruit ---- apple ---- banana ---- orange -- veg ---- cucumber ---- lettuce drinks -- alcoholic ---- beer ---- vodka misc -- household objects ---- kitchen ------ electrical -------- cooking ---------- stove ---------- toaster ---------- microwave note needs work around 10 'levels'. i'd love infinite dont want going down route of using nested set model it'll cause huge delays on project. the docs on laravel terrible, no real reference start. i've been playing days trying work out , seem getting without huge messy block of each loops within each other 10 times. i've got tree of data using following in model: <?php class item extends eloquent { public function parent() { return $this->hasone('item', 'id', 'parent_id'); }

i made custom widget "duwagwidget" , custom widget plugin "duwagwidgetplugin" can dragged&dropped inside qt designer create duwag.ui file. however, when try compile program, ui_duwag.h generated qt user interface compiler, in auto generated file, uic not include "duwagwidget.h" necessary create custom widget class. the duwagwidgetplugin (derived interface in qt create customwidgets) factory class duwagwidget. here code duwagwidgetplugin :^ #include <duwagwidgetplugin.h> #include <qtplugin> #include <qwidget.h> #include <mtbfwidget.h> duwagwidgetplugin::duwagwidgetplugin( qobject *parent ) : qobject(parent) { initialized = false; } void duwagwidgetplugin::initialize(qdesignerformeditorinterface * /* core */) { if (initialized) return; initialized = true; } bool duwagwidgetplugin::isinitialized() const { return initialized; }

i wanted access application config view. how can achieve in zf 2? actually shouldn't need access application config inside view. in mvc, views responsible displaying/rendering data (output) , shouldn't contain business or application logic. if want can pass view in controller this: <?php namespace yourmodule\controller; use zend\view\model\viewmodel; // ... public function anyaction() { $config = $this->getservicelocator()->get('config'); $viewmodel = new viewmodel(); $viewmodel->setvariables(array('config' => $config )); return $viewmodel; } // ... ?> so in view.phtml file; <div class="foo"> ... <?php echo $this->config; ?> ... </div>

since startup items , rc commands both deprecated (and in many cases not working @ all) on os x in favour of launchd , i'd find out correct way setup shell script runs on logout/shutdown. for startup item possible create shell script looked like: #!/bin/sh startservice() { echo "started." } stopservice() { echo "stopped." } runservice "$1" but runservice command isn't supported when running script launchd , , i'm not sure it's meant used anymore anyway. if possible, i'd create shell script provided launchd on-demand service started near shutdown , somehow informed system shutting down. alternatively, may need shell script opened on login/system start , remains running (or rather, asleep) until sigterm or other kill signal received, can run commands before closing. @gaige reply! in end went following: #!/bin/sh startservice() { echo "started" } stopservice() { echo "stopped&q

i'm trying implement own version of session handler using mysql in php. version differs existing ones (like zend's) in mine namespaced , each namespace stored , locked separately. here's scenario should implemented in code: acquire exclusive lock sid+ns read sid+ns's data ... request takes course ... write sid+ns's data db release lock sid : session id - ns : namespace now question arises is: how use exclusive locks in mysql? there number of issues 1 needs keep in mind before answering question: there arbitrary number of namespaces in each session. one single request might need hold more 1 ex-locks (one request might need work on more 1 namespace @ time). locks need implemented using mysql's internal mechanism. implementing own application-level ex-locks pretty simple. have implement queues , semaphores mimic same behavior mysql giving makes hard. i'm saying want code work on of machines without going through heavy changes , i'm

i'm quite confused on how build models, failed understand last 9 months. although reading , watching references , @teresko gave me. to further narrow down question, i'll give example of how did before. lets have student entity has student_number , first_name, last_name` i create called model , (my professor did same, know quite wrong). don't know if professor knows value objects, do. private $student_number; private $first_name; private $last_name; public function setstudentnumber($sn) {$this->student_number = $sn} public function getstudentnumber() {return $this->student_number} ... , on other properties if correct, setters , getters classified value object pattern, can used this: $s = new student(); $s->setstudentnumber(143); $s->setfirstname('fooname'); $s->setlastname('barname'); and pass in data access object (studentdao) this: $sdao = new studentdao($s); $sdao->add(); where dao extends database class, can crud

i'm developing eclipse plugin. building , deploying supported tycho , maven. add googles guava v. 14 project dependency. on tychos wiki page have found can resolve dependencies if osgi bundles. not able find version of guava osgi bundle. common workaround situation? check out interested revision guava repository, add manifest , bundle , add projects path, seams me dirty workaround — need maintain bundle myself, can't upgrade bundle, need commit binary in vcs ci. doing same storing bundle in maven repository — maintaining repository source code duplicates existing, upgrading not simple to. it seams me very-very hard import existing java code in osgi projects. don't try convert library osgi bundle yourself: either, simple turn library osgi bundle, e.g. if correct manifest can generated using 1 of bnd based tools. in case, provider of library should directly. maven build, they'd need add bundle goal of maven-bundle-plugin . or, hard turn librar

okay question find few proper arguments for/against. i appreciate value these patterns provide testability , separation of concerns. in cases have sort of data store(s), presented user in different ways. but consider application each model bound 1 view. example maybe audio format converter, small gui sitting on (a) big api(s) back-end. ui needs basic validation (for paths , formats), , rest left back-end. would benefit of using 1 such pattern here justify code? personally, see unneeded overhead, may wrong, hence question. :-) edit: the example application wrote here seems have been distracting people main point of question. i'm asking when mvp/mvc not good. here's quote golden 4: no discussion of how use design patterns complete without few words on how not use them. design patterns should not applied indiscriminately. achieve flexibility , variability introducing additional levels of indirection, , can complicate design and/or cost performance. design patt

i'm pretty new web development. best practice in keeping same sidebar , other elements across web pages on one's site? store sidebar html , call that? if so, how 1 go doing that? here's one way it: use "include" files . no javascript required. server work, instead of requiring client add content. ssi, or server side includes, first developed allow web developers "include" html documents inside other pages. if web server supports ssi, it's easy create templates web site. save html common elements of site separate files. example, navigation section might saved navigation.html or navigation.ssi. use following ssi tag include html in each page. <!--#include virtual="path file/include-file.html" --> use same code on every page want include file. that page describes other approaches. if know called using include files, can search more easily. example, this article describes includes , how c

does python stores similar objects @ memory locations nearer each other? because id of similar objects, lists , tuples , nearer each other object of type str . no, except of course coincidence. while highly implementation- , environment-specific, , there memory management schemes dedicate page-sized memory regions objects of same type, no python implementations i'm aware of exhibits behavior describe. possible exception of small numbers, cached under hood , located next each other. what you're seeing may because string literals created @ import time (part of constants in byte code) , interned, while lists , tuples (that don't contain literals) created while running code. if bunch of memory allocated in between ( especially if isn't freed), state of heap may sufficiently different quite different addresses handed out when you're checking.

i'm pretty new vba, , i'm having problem on comparison of 2 columns (all of data under 2 columns). the workflow is, column compare column b result put in column c. column (column d) used comparison (all of columns in 1 worksheet). the logic this: compare column column b if column b blank, put "no value here" if column b has value (sample value: product-id), compare b column d (sample value: pi, abbreviation of product-id) if matched put "matched". if no matches, put "no match" instead of vba, here solution using formulas in worksheet in column c want apply rule: if b="" "no value here" else if b=d "matched" else "not matched" end if you can below formula in column c (then filled down) =if(b:b="","no value here",if(b:b=d:d,"matched","not matched"))

i need assistance creating query following result: i have 2 tables accounts, lists users , how initial owe , payments, holds records of payments users have made. know how merge tables join don't know how math needed owed amount , paid amounts. the columns in accounts consist of: id, name, account, borrowed columns in payments consist of: id, acctid, paymentamt i need query combine both of these tables , math show how user has paid , how user still owes initial borrowed amount. example table data: accounts table id = 3, name = joe, account = business, borrowed = 100.00 payments table id = 1, acctid = 3, paymentamt = 10.00 id = 2, acctid = 3, paymentamt = 10.00 i using ms sql in c#. you need join , use sum , group by. select a.name , a.account , a.borrowed - coalesce(sum(p.paymentamt),0) [still owes], coalesce(sum(p.paymentamt),0) paid, a.borrowed accounts left join payments p on a.id = p.acctid

i wondering if there pythonic way of adding 2 tuples elementwise? so far (a , b tuples), have map(sum, zip(a, b)) my expected output be: (a[0] + b[0], a[1] + b[1], ...) and possible weighing give 0.5 weight , b 0.5 weight, or on. (i'm trying take weighted average). which works fine, wanted add weighting, i'm not quite sure how that. thanks zip them, sum each tuple. [sum(x) x in zip(a,b)] edit : here's better, albeit more complex version allows weighting. from itertools import starmap, islice, izip = [1, 2, 3] b = [3, 4, 5] w = [0.5, 1.5] # weights => a*0.5 + b*1.5 products = [m m in starmap(lambda i,j:i*j, [y x in zip(a,b) y in zip(x,w)])] sums = [sum(x) x in izip(*[islice(products, i, none, 2) in range(2)])] print sums # should [5.0, 7.0, 9.0]

i trying read xml file , store structure array of objects. here code: class bike attr_accessor :id, :color, :name def initialize(id, color, name) @id = id @color = color @name = name end end ---x---snip---x--- rules.root.each_element |node1| case node1.name when "bike" bike = bike.new(node1.attributes['id'], node1.attributes['color'], { |bike_elem| bike_elem.text.chomp if bike_elem.name == "name"}) bikes.push bike end end however, last element not fetching value alone. fetching whole tag. there better way it? your code block { |bike_elem| bike_elem.text.chomp if bike_elem.name == "name" } doesn't seem make sense inside new parameter list. where bike_elem come from? not valid ruby in context. it's hard give answer here without knowing xml looks like. recommend using xml library nokogiri, libxml, , parse out name before new . try using xpath .
