• why isn't my id showing up in django admin list?

  - by FurtiveFelon

  Hi all, I have a class Task(models.Model), and i didn't define id field explicitly (since it defines automatically for you). I checked in the database, it exists for the Task. Now i would like to display it in the list via list_display property in admin.ModelAdmin. I have a bunch of things in there, only id is not showing up for any of the rows i have. Everything else works fine. Anyone know anything special i have to do to get id to display? Thanks a lot! Jason

• CGAL replacement for iOS

  - by Aleks N.

  I have a set of nodes that define streets. Each node has latitude and longitude. Also I have user location with latitude and longitude. My intention is to build Voronoi diagram for segments defined by each pair of nodes, and then find which node user location is closest to. Looks like this task can be accomplished with CGAL library. While I'm in the process of compiling it for iOS environment, probably you guys will be able to give links to libs that are already compiled against iOS, or were intended to be used in Objective C environment from the very beginning... Because I'm afraid that even if CGAL compiles for me, I might get into trouble when using it. Thanks!

• Seeking tutorial: introduction to ODBC with Delphi

  - by mawg

  I have a lot of embedded C/C++/Ada experience and an outdated smattering of Delphi plus some database stuff. Now I have to implement an app in Delphi which can manipulate MySql, Oracle, maybe MS Access. In short, I need ODBC. I need to programmatically created a database, define its structure and populate its contents, then later query its existence and programmatically search. I would prefer not to use 3rd party components, unless there is a compelling reason to do so (performance ought not to be an issue for the app, it won't have much data or be run often, at least not in v1.0) . Can anyone point me at a tutorial which can get me up to speed? Thanks

• PHP APC - Why is loading cached array op codes slow?

  - by Aaron Kreider

  I'm using APC to reduce my loading time for my PHP files. My files load very fast, except for one file where I define more than 100 arrays. This 270 kb file takes 200 ms to load. The rest of the files are full of objects, methods, and functions. I'm wondering: does OP code caching not work as well for arrays? My APC cache should be big enough to handle all of my classes. Currently 40% of my cache is free. My hit rate is 99%. apc.shm_size=32 M apc.max_file_size = 1M apc.shm_segments= 1 APC 3.1.6 I'm using PHP 5.2, Apache 2, and Windows Vista.

• Can't inherit from auto_ptr without problems

  - by fret

  What I want to do is this: #include <memory> class autostr : public std::auto_ptr<char> { public: autostr(char *a) : std::auto_ptr<char>(a) {} autostr(autostr &a) : std::auto_ptr<char>(a) {} // define a bunch of string utils here... }; autostr test(char a) { return autostr(new char(a)); } void main(int args, char **arg) { autostr asd = test('b'); return 0; } (I actually have a copy of the auto_ptr class that handles arrays as well, but the same error applies to the stl one) The compile error using GCC 4.3.0 is: main.cpp:152: error: no matching function for call to `autostr::autostr(autostr)' main.cpp:147: note: candidates are: autostr::autostr(autostr&) main.cpp:146: note: autostr::autostr(char*) I don't understand why it's not matching the autostr argument as a valid parameter to autostr(autostr&).

• In MAYA 2009, is it possible to capture the cube rotate event?

  - by Rahul2047

  I need to call a function ( Maya-Python ) based on cube rotationX. For that I have to capture the event, programmatically. I tried using while loop but It stucks in the loop, Nothing can be done in that time. I tried theading (python), still same. Can it be done this or other way? If yes, How? Maya 2009 in Windows XP Some failed code references: import maya.cmds as cmds while (count < 90): lock = cmds.getAttr('pCube1.rotateX',lock=False) print lock count = count + 1 Here Python wise: #!/usr/bin/python import thread import time # Define a function for the thread def cubeRotateX( threadName, delay): count = 0 while count < 5: time.sleep(delay) count += 1 try: thread.start_new_thread( cubeRotateX, ("Thread-1", 2, ) ) except: print "Error: unable to start thread" while 1: pass

• Conditional type definitions

  - by pythonic metaphor

  I'm sure that boost has some functions for doing this, but I don't know the relevant libraries well enough. I have a template class, which is pretty basic, except for one twist where I need to define a conditional type. Here is the psuedo code for what I want struct PlaceHolder {}; template <typename T> class C{ typedef (T == PlaceHolder ? void : T) usefulType; }; How do I write that type conditional?

• Log information inside a JUnit Suite

  - by Alex Marinescu

  I'm currently trying to write inside a log file the total number of failed tests from a JUnite Suite. My testsuite is defined as follows: @RunWith(Suite.class) @SuiteClasses({Class1.class, Class2.class etc.}) public class SimpleTestSuite {} I tried to define a rule which would increase the total number of errors when a test fails, but apparently my rule is never called. @Rule public MethodRule logWatchRule = new TestWatchman() { public void failed(Throwable e, FrameworkMethod method) { errors += 1; } public void succeeded(FrameworkMethod method) { } }; Any ideas on what I should to do to achieve this behaviour?

• Parsing a text file with a fixed format in Java

  - by EugeneP

  Suppose I know a text file format, say, each line contains 4 fields like this: firstword secondword thirdword fourthword firstword2 secondword2 thirdword2 fourthword2 ... and I need to read it fully into memory I can use this approach: open a text file while not EOF read line by line split each line by a space create a new object with four fields extracted from each line add this object to a Set Ok, but is there anything better, a special 3-rd party Java library? So that we could define the structure of each text line beforehand and parse the file with some function thirdpartylib.setInputTextFileFormat("format.xml"); thirdpartylib.parse(Set, "pathToFile") ?

• Make Excel Defined Names within a worksheet to be global

  - by idazuwaika

  Hi, I wrote Powershell script to copy a worksheet from a workbook A to another workbook B. The worksheet contains define names for ranges within that sheet. Originally, the defined names are global in workbook A, ie. can be referenced from any worksheets within workbook A. But now, after copy to worksheet B, the defined names are limited to that worksheet only. How to I programmatically (via Powershell script preferably) make all those named range global i.e. can be referenced from all worksheets within workbook B. Some codes for clarity. #Script to update SOP from 5.1 to 5.2 $missing = [System.Type]::missing #Open files $excel = New-Object -Com Excel.Application $excel.Visible = $False $excel.DisplayAlerts = $False $newTemplate = "C:\WorkbookA.xls" $wbTemplate = $excel.Workbooks.Open($newTemplate) $oldSop = "C:\WorkbookB.xls" $wbOldSop = $excel.Workbooks.Open($oldSop) #Delete 'DATA' worksheet from old file $wsOldData = $wbOldSop.Worksheets.Item("DATA") $wsOldData.Delete() #Copy new 'DATA' worksheet to old file $wbTemplate.Worksheets.Item("DATA").Copy($missing,$wbOldSop.Worksheets.Item("STATUS")) #Save $wbOldSop.Save() $wbOldSop.Close() #Quit Excel $excel.Quit()

• Better Java method Syntax? Return early or late? [closed]

  - by Gandalf

  Duplicate: Should a function have only one return statement? and Single return or multiple return statements? Often times you might have a method that checks numerous conditions and returns a status (lets say boolean for now). Is it better to define a flag, set it during the method, and return it at the end : boolean validate(DomainObject o) { boolean valid = false; if (o.property == x) { valid = true; } else if (o.property2 == y) { valid = true; } ... return valid; } or is it better/more correct to simply return once you know the method's outcome? boolean validate(DomainObject o) { if (o.property == x) { return true; } else if (o.property2 == y) { return true; } ... return false; } Now obviously there could be try/catch blocks and all other kinds of conditions, but I think the concept is clear. Opinions?

• Best approch to dynamically filter .net objects

  - by maxba

  The project i´m working currently on has a way to define a filter to filter objects from a database. This filter is a pretty straitforward class containing filtercriteria that will be combined to a sql where-clause. The goal now is to use this filter class to filter .net objects as well. So the filter for example defines, that the title property of the object that it is applied to must contain some userdefined string etc. What are ways to approch this problem? What should the filter return instead of the sql where-clause and how can it be applied to the object? I´m thinking about this for hours and don´t yet have even a slight idea how to solve this. Been thinking about reflection, dynamic code execution, building expressions but still haven´t found an acutal starting point.

• Merging photo textures - (from calibrated cameras) - projected onto geometry

  - by freakTheMighty

  I am looking for papers/algorithms for merging projected textures onto geometry. To be more specific, given a set of fully calibrated cameras/photographs and geometry, how can we define a metric for choosing which photograph should be used to texture a given patch of the geometry. I can think of a few attributes one may seek minimize including the angle between the surface normal and the camera, the distance of the camera from the surface, as well as minimizing some parameterization of sharpness. The question is how do these things get combined and are there well established existing solutions?

• Combining 2 PHP frameworks that both implement __() internationalization function

  - by mclin

  Never had a question I couldn't google until now, and it may be a doozy: I have a PHP site that combines Wordpress with Kohana - Wordpress for the blog, and Kohana for the custom functionality. This is done using a Wordpress plugin that stitches them together. This works great except they both define a __() internationalization function, with different arguments etc. so once wordpress has overridden kohana's __(), if kohana calls __() it explodes. I'm not that familiar with PHP so this might be naive, but shouldn't this stuff be namespaced? Is there anyway other than changing the source of one or the other framework to allow them to call their own respective __()?

• Indexes and multi column primary keys

  - by David Jenings

  Went searching and didn't find the answer to this specific noob question. My apologies if I missed it. In a MySQL database I have a table with the following primary key PRIMARY KEY id (invoice, item) In my application I will also frequently be selecting on "item" by itself and less frequently on only "invoice". I'm assuming I would benefit from indexes on these columns. MySQL does not complain when I define the following: INDEX (invoice), INDEX (item), PRIMARY KEY id (invoice, item) But I don't see any evidence (using DESCRIBE -- the only way I know how to look) that separate indexes have been established for these two columns. So the question is, are the columns that make up a primary key automatically indexed individually? Also, is there a better way than DESCRIBE to explore the structure of my table?

• How to have type hinting in PHP that specifies variable scope inside of a template? (specifically PhpStorm)

  - by Lance Rushing

  I'm looking for a doc comment that would define the scope/context of the current php template. (similar to @var) Example View Class: <?php class ExampleView { protected $pageTitle; public function __construct($title) { $this->pageTitle = $title; } public function render() { require_once 'template.php'; } } -- <?php // template.php /** @var $this ExampleView */ echo $this->pageTitle; PHPStorm gives an inspection error because the access on $pageTitle is protected. Is there a hint to give scope? Something like: <?php // template.php /** @scope ExampleView */ // <---???? /** @var $this ExampleView */ echo $this->pageTitle;

• Any reccomendations for implementing a user-defined workflow in Ruby?

  - by midas06

  I'm interested in creating a system where the user can define the steps in a workflow. Is there a gem that already handles this? I thought about one of the state machine gems, but they all seem to be for pre-defined states. I've been thinking maybe i can use state machine for the individual step types... An email step could have a few states [New, Assigned, Done], and the workflow could just be lists of these stateful steps. Are there other solutions out there?

• Automatic initialization routine in C++ library?

  - by Robert Mason

  If i have a header file foo.h and a source file foo.cpp, and foo.cpp contains something along the lines of: #ifdef WIN32 class asdf { asdf() { startup_code(); } ~asdf() { cleanup_code(); } }; asdf __STARTUP_HANDLE__ #else //unix does not require startup or cleanup code in this case #endif but foo.h does not define class asdf, say i have an application bar.cpp: #include "foo.h" //link in foo.lib, foo.dll, foo.so, etc int main() { //do stuff return 0; } If bar.cpp is compiled on a WIN32 platform, will the asdf() and ~asdf() be called at the appropriate times (before main() and at program exit, respectively) even though class asdf is not defined in foo.h, but is linked in through foo.cpp?

• Prevent Carousel scroll within scrollable Container (Sencha 2)?

  - by TragedyStruck

  I've got a Container with a header, content (Carousel) and a footer. The Container itself is therefor scrollable (vertical) to be able to scroll down to the footer. The Carousel can be swiped horizontally to change active item. I want to lock it to do only two thing: If starting to move vertically, only scroll Container If starting to move horizontally, only scroll Carousel If you now grab the Carousel you are able to scroll both ways at the same time. Example code: Ext.define('MyApp.view.MyContainer', { extend: 'Ext.Container', config: { scrollable: true, items: [ { xtype: 'container', items: [ { xtype: 'label', html: 'abc' } ] }, { xtype: 'carousel', height: 200, scrollable: false, items: [ { xtype: 'label', html: 'x' }, { xtype: 'label', html: 'y<br/>y<br/>y<br/>y<br/>y<br/>y<br/>y<br/>y' } ] }, { xtype: 'container', items: [ { xtype: 'label', html: 'def' } ] } ] } }); Using Sencha Touch 2.

• Instance where embedded C++ compilers don't support multiple inheritance?

  - by Nathan

  I read a bit about a previous attempt to make a C++ standard for embedded platforms where they specifically said multiple inheritance was bad and thus not supported. From what I understand, this was never implemented as a mainstream thing and most embedded C++ compilers support most standard C++ constructs. Are there cases where a compiler on a current embedded platform (i.e. something not more than a few years old) absolutely does not support multiple inheritance? I don't really want to do multiple inheritance in a sense where I have a child with two full implementations of a class. What I am most interested in is inheriting from a single implementation of a class and then also inheriting one or more pure virtual classes as interfaces only. This is roughly equivalent to Java/.Net where I can extend only one class but implement as many interfaces as I need. In C++ this is all done through multiple inheritance rather than being able to specifically define an interface and declare a class implements it.

• <function> referenced from; symbol(s) not found.

  - by jfm429

  I have a piece of C code that is used from a C++ function. At the top of my C++ file I have the line: #include "prediction.h" In prediction.h I have this: #ifndef prediction #define prediction #include "structs.h" typedef struct { double estimation; double variance; } response; response runPrediction(int obs, location* positions, double* observations, int targets, location* targetPositions); #endif I also have prediction.c, which has: #include "prediction.h" response runPrediction(int obs, location* positions, double* observations, int targets, location* targetPositions) { // code here } Now, in my C++ file (which as I said includes prediction.h) I call that function, then compile (through Xcode) I get this error: "runPrediction(int, location*, double*, int, location*)", referenced from: mainFrame::respondTo(char*, int)in mainFrame.o ld: symbol(s) not found collect2: ld returned 1 exit status prediction.c is marked for compilation for the current target. I don't have any problems with other .cpp files not being compiled. Any thoughts here?

• Spring & Hibernate EJB Events

  Is it possible to define a spring-managed EJB3 hibernate listener? I have this definition in my persistence.xml: <properties> <property name="hibernate.ejb.interceptor" value="my.class.HibernateAuditInterceptor" /> <property name="hibernate.ejb.event.post-update" value="my.class.HibernateAuditTrailEventListener" /> </properties> But I would like to manage HibernateAuditInterceptor and HibernateAuditTrailEventListener with spring, so I can do some bean injection (ex: session-scoped bean) within these classes. Is this possible?

• Testing whether an event has happened after a period of time in jQuery

  - by chrism

  I'm writing a script for a form-faces xforms product that is keyed off an event built into form faces. The event is called 'xforms-ready'. I have define 'startTime' as happening as soon as the document in 'ready'. What I want the script to do is warn the user that it is taking too long before the 'xforms-ready' happens, say if it's been 6 seconds since 'startTime'. I can easily do things when the 'xforms-ready' event happens using the code below: new EventListener(document.documentElement, "xforms-ready", "default", function() { var endTime = (new Date()).getTime(); } ); however the warning will want to happen before 'endTime' is defined. So I guess I want something that works like this: If 6 seconds has passed since startTime and endTime is not yet defined do X or possibly more efficiently: If 6 seconds has passed since startTime and 'xforms-ready' has not yet happened do X Can anyone suggest a way of doing this?
