• Positioning / Scrolling problem with Flex popup.

  - by user284163

  Hi all, I'm trying to work out a specific problem I'm having with positioning in Flex using the PopUpManager. Basically I'm wanting to create a popup which will scroll with the parent container - this is necessary because the parent container is large and if the user's browser window isn't large enough (this will be the case the majority of the time) - they will have to use the scrollbar of the container to scroll down. The problem is that the popup is positioned relative to another component, and it needs to stay by that component. <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <![CDATA[ import mx.core.UITextField; import mx.containers.TitleWindow; import mx.managers.PopUpManager; private function clickeroo(event:MouseEvent):void { var popup:TitleWindow = new TitleWindow(); popup.width = 250; popup.height = 300; popup.title = "Example"; var tf:UITextField = new UITextField(); tf.wordWrap = true; tf.width = popup.width - 30; tf.text = "This window stays put and doesn't scroll when the hbox is scrolled (even with using the hbox as parent in the addPopUp method), I need the popup to be local to the HBox."; popup.addChild(tf); PopUpManager.addPopUp(popup, hbox, false); PopUpManager.centerPopUp(popup); } ]]> </mx:Script> <mx:HBox width="100%" height="2000" id="hbox"> <mx:Button label="Click Me" click="clickeroo(event)"/> </mx:HBox> </mx:Application> Could anyone give me any pointers in the right direction? Thanks.

• MySQLdb within python2.5 virtualenv

  - by wizard

  I have a Fedora 11 box with MySQL server. Fedora 11 uses python 2.6 internally and python 2.6 is automatically installed on the box. I have created a python virtual-env for version 2.5.5, so that I can run turbogears 1.x application. I have MySQLdb rpm installed on the box (and it works fine with python 2.6). When I import MySQLdb from within python version 2.6 it imports is successfully. When I import MySQLdb from within the python 2.5.5 virtual-env the import fails (because I have installed virtual-env with --no-site-packages). So, I have to install MySQLdb python as a local package (local to virtual-env). 'easy_install MySQL-python' within the virtual env fails. It downloads the MySQL-python-1.2.3.c1.tar.gz/download, but the 'python setup.py build' fails with error. The same problem occurs when building the MySQL outside of virtual-env. Is the 'python setup.py build' for MySQL-python trying to link to a library (and am I missing some library)? Or is the downloaded code missing some header files (unlikely)? Thanks.

• How can I pass extra parameters to the routeMatch object?

  - by Marcos Garcia

  I'm trying to unit test a controller, but can't figure out how to pass some extra parameters to the routeMatch object. I followed the posts from tomoram at http://devblog.x2k.co.uk/unit-testing-a-zend-framework-2-controller/ and http://devblog.x2k.co.uk/getting-the-servicemanager-into-the-test-environment-and-dependency-injection/, but when I try to dispatch a request to /album/edit/1, for instance, it throws the following exception: Zend\Mvc\Exception\DomainException: Url plugin requires that controller event compose a router; none found Here is my PHPUnit Bootstrap: class Bootstrap { static $serviceManager; static $di; static public function go() { include 'init_autoloader.php'; $config = include 'config/application.config.php'; // append some testing configuration $config['module_listener_options']['config_static_paths'] = array(getcwd() . '/config/test.config.php'); // append some module-specific testing configuration if (file_exists(__DIR__ . '/config/test.config.php')) { $moduleConfig = include __DIR__ . '/config/test.config.php'; array_unshift($config['module_listener_options']['config_static_paths'], $moduleConfig); } $serviceManager = Application::init($config)->getServiceManager(); self::$serviceManager = $serviceManager; // Setup Di $di = new Di(); $di->instanceManager()->addTypePreference('Zend\ServiceManager\ServiceLocatorInterface', 'Zend\ServiceManager\ServiceManager'); $di->instanceManager()->addTypePreference('Zend\EventManager\EventManagerInterface', 'Zend\EventManager\EventManager'); $di->instanceManager()->addTypePreference('Zend\EventManager\SharedEventManagerInterface', 'Zend\EventManager\SharedEventManager'); self::$di = $di; } static public function getServiceManager() { return self::$serviceManager; } static public function getDi() { return self::$di; } } Bootstrap::go(); Basically, we are creating a Zend\Mvc\Application environment. My PHPUnit_Framework_TestCase is enclosed in a custom class, which goes like this: abstract class ControllerTestCase extends TestCase { /** * The ActionController we are testing * * @var Zend\Mvc\Controller\AbstractActionController */ protected $controller; /** * A request object * * @var Zend\Http\Request */ protected $request; /** * A response object * * @var Zend\Http\Response */ protected $response; /** * The matched route for the controller * * @var Zend\Mvc\Router\RouteMatch */ protected $routeMatch; /** * An MVC event to be assigned to the controller * * @var Zend\Mvc\MvcEvent */ protected $event; /** * The Controller fully qualified domain name, so each ControllerTestCase can create an instance * of the tested controller * * @var string */ protected $controllerFQDN; /** * The route to the controller, as defined in the configuration files * * @var string */ protected $controllerRoute; public function setup() { parent::setup(); $di = \Bootstrap::getDi(); // Create a Controller and set some properties $this->controller = $di->newInstance($this->controllerFQDN); $this->request = new Request(); $this->routeMatch = new RouteMatch(array('controller' => $this->controllerRoute)); $this->event = new MvcEvent(); $this->event->setRouteMatch($this->routeMatch); $this->controller->setEvent($this->event); $this->controller->setServiceLocator(\Bootstrap::getServiceManager()); } public function tearDown() { parent::tearDown(); unset($this->controller); unset($this->request); unset($this->routeMatch); unset($this->event); } } And we create a Controller instance and a Request with a RouteMatch. The code for the test: public function testEditActionWithGetRequest() { // Dispatch the edit action $this->routeMatch->setParam('action', 'edit'); $this->routeMatch->setParam('id', $album->id); $result = $this->controller->dispatch($this->request, $this->response); // rest of the code isn't executed } I'm not sure what I'm missing here. Can it be any configuration for the testing bootstrap? Or should I pass the parameters in some other way? Or am I forgetting to instantiate something?

• Using the groupby method in Python, example included

  - by randombits

  Trying to work with groupby so that I can group together files that were created on the same day. When I say same day in this case, I mean the dd part in mm/dd/yyyy. So if a file was created on March 1 and April 1, they should be grouped together because the "1" matches. Here's the code I have so far: #!/usr/bin/python import os import datetime from itertools import groupby def created_ymd(fn): ts = os.stat(fn).st_ctime dt = datetime.date.fromtimestamp(ts) return dt.year, dt.month, dt.day def get_files(): files = [] for f in os.listdir(os.getcwd()): if not os.path.isfile(f): continue y,m,d = created_ymd(f) files.append((f, d)) return files files = get_files() for key, group in groupby(files, lambda x: x[1]): for file in group: print "file: %s, date: %s" % (file[0], key) print " " The problem is, I get lots of files that get grouped together based on the day. But then I'll see multiple groups with the same day. Meaning I might have 4 files grouped that were created on the 17th. Later on I'll see another unique set of 2 files that are also created on the 17th. Where am I going wrong?

• Add new language to existing Xcode project localization

  - by leolobato

  Hey guys, I'm working on an existing Xcode 3.2.2 Universal iPhone OS project which is already localized for 4 languages (EN, IT, DE and FR). We are now adding a new language (JA) into this project. Each existing .lproj folder (en.lproj, it.lproj, de.lproj and fr.lproj) has almost 60 files - including PNGs, HTMLs and the Localizable.strings file. Each one of those files appear as localized groups inside Groups & Files in Xcode. They're spread all over the tree. If I right-click one of those groups (say, Localizable.strings) inside Xcode, Get Info, click on "Add Localization" and type "ja" - as the Xcode docs suggest, nothing happens. From what I read in this newgroup, it's possibly because of the way those folders are named. If they were named like English.lproj and Italian.lproj, this was supposed to work. So, for me to actually import a new language localized file into the existing group, I have to: Right-click the localized group file. Choose "Add Existing File". Select the corresponding file inside the ja.lproj folder. I'm about to get a new ja.lproj folder with those 60 localized files and would love to import them in the project in a way that doesn't involve searching for every single file in Groups & Trees and performing those steps... for every one of those 60 files. Is that possible? Is there a right (or better) way to import a new language into this Xcode project?

• Python: puzzling behaviour inside httplib

  - by Anna

  I have added one line ( import pdb; pdb.set_trace() ) to httplib's HTTPConnection.putheader, so I can see what's going on inside. httplib.py, line 489: def putheader(self, header, value): """Send a request header line to the server. For example: h.putheader('Accept', 'text/html') """ import pdb; pdb.set_trace() if self.__state != _CS_REQ_STARTED: raise CannotSendHeader() str = '%s: %s' % (header, value) self._output(str) then ran this from the interpreter import urllib2 urllib2.urlopen('http://www.ioerror.us/ip/headers') ... and as expected PDB kicks in: > c:\python26\lib\httplib.py(858)putheader() -> if self.__state != _CS_REQ_STARTED: (Pdb) in PDB I have the luxury of evaluating expressions on the fly, so I have tried to enter self.__state: (Pdb) self.__state *** AttributeError: HTTPConnection instance has no attribute '__state' Alas, there is no __state of this instance. However when I enter step, the debugger gets past the if self.__state != _CS_REQ_STARTED: line without a problem. Why is this happening? If the self.__state doesn't exist python would have to raise an exception as it did when I entered the expression. Python version: 2.6.4 on win32

• Niewbie OutOfMemory problem

  - by Nick

  So I am trying to create a producer/consumer type scala app. The LoopControl just sends a message to the MessageReceiver continoually. The MessageReceiver then delegates work to the MessageCreatorActor (whose work is to check a map for an object, and if not found create one and start it up). Each MessageActor created by this MessageCreatorActor is associated with an Id. Eventually this is where I want to do business logic. But I run out of memory after 15 minutes. Any help is appreciated import scala.actors.Actor import java.util.HashMap; import scala.actors.Actor._ case object LoopControl case object MessageReceiver case object MessageActor case object MessageActorCreator class MessageReceiver(msg: String) extends Actor { var messageActorMap = new HashMap[String, MessageActor] val messageCreatorActor = new MessageActorCreator(null, null) def act() { messageCreatorActor.start loop { react { case MessageActor(messageId) = if (msg.length() 0) { var messageActor = messageActorMap.get(messageId); if(messageActor == null) { messageCreatorActor ! MessageActorCreator(messageId, messageActorMap) }else { messageActor ! MessageActor } } } } } } case class MessageActorCreator(msg:String, messageActorMap: HashMap[String, MessageActor]) extends Actor { def act() { loop { react { case MessageActorCreator(messageId, messageActorMap) = if(messageId != null ) { var messageActor = new MessageActor(messageId); messageActorMap.put(messageId, messageActor) println(messageActorMap) messageActor.start messageActor !

• Wrapping FUSE from Go

  - by Matt Joiner

  I'm playing around with wrapping FUSE with Go. However I've come stuck with how to deal with struct fuse_operations. I can't seem to expose the operations struct by declaring type Operations C.struct_fuse_operations as the members are lower case, and my pure-Go sources would have to use C-hackery to set the members anyway. My first error in this case is "can't set getattr" in what looks to be the Go equivalent of a default copy constructor. My next attempt is to expose an interface that expects GetAttr, ReadLink etc, and then generate C.struct_fuse_operations and bind the function pointers to closures that call the given interface. This is what I've got (explanation continues after code): package fuse // #include <fuse.h> // #include <stdlib.h> import "C" import ( //"fmt" "os" "unsafe" ) type Operations interface { GetAttr(string, *os.FileInfo) int } func Main(args []string, ops Operations) int { argv := make([]*C.char, len(args) + 1) for i, s := range args { p := C.CString(s) defer C.free(unsafe.Pointer(p)) argv[i] = p } cop := new(C.struct_fuse_operations) cop.getattr = func(*C.char, *C.struct_stat) int {} argc := C.int(len(args)) return int(C.fuse_main_real(argc, &argv[0], cop, C.size_t(unsafe.Sizeof(cop)), nil)) } package main import ( "fmt" "fuse" "os" ) type CpfsOps struct { a int } func (me *CpfsOps) GetAttr(string, *os.FileInfo) int { return -1; } func main() { fmt.Println(os.Args) ops := &CpfsOps{} fmt.Println("fuse main returned", fuse.Main(os.Args, ops)) } This gives the following error: fuse.go:21[fuse.cgo1.go:23]: cannot use func literal (type func(*_Ctype_char, *_Ctype_struct_stat) int) as type *[0]uint8 in assignment I'm not sure what to pass to these members of C.struct_fuse_operations, and I've seen mention in a few places it's not possible to call from C back into Go code. If it is possible, what should I do? How can I provide the "default" values for interface functions that acts as though the corresponding C.struct_fuse_operations member is set to NULL?

• Why is iPdb not displaying STOUT after my input?

  - by BryanWheelock

  I can't figure out why ipdb is not displaying stout properly. I'm trying to debug why a test is failing and so I attempt to use ipdb debugger. For some reason my Input seems to be accepted, but the STOUT is not displayed until I (c)ontinue. Is this something broken in ipdb? It makes it very difficult to debug a program. Below is an example ipdb session, notice how I attempt to display the values of the attributes with: user.is_authenticated() user_profile.reputation user.is_superuser The results are not displayed until 'begin captured stdout ' In [13]: !python manage.py test Creating test database... < SNIP remove loading tables nosetests ...E.. /Users/Bryan/work/APP/forum/auth.py(93)can_retag_questions() 92 import ipdb; ipdb.set_trace() ---> 93 return user.is_authenticated() and ( 94 RETAG_OTHER_QUESTIONS <= user_profile.reputation < EDIT_OTHER_POSTS or user.is_authenticated() user_profile.reputation user.is_superuser c F /Users/Bryan/work/APP/forum/auth.py(93)can_retag_questions() 92 import ipdb; ipdb.set_trace() ---> 93 return user.is_authenticated() and ( 94 RETAG_OTHER_QUESTIONS <= user_profile.reputation < EDIT_OTHER_POSTS or c .....EE......

• How to update QStandartItemModel without freezing the main UI

  - by user1044002

  I'm starting to learn PyQt4 and have been stuck on something for a long time now and can't figure it out myself: Here is the concept: There is a TreeView with custom QStandartItemModel, which gets rebuild every couple of seconds, and can have a lot (hundreds at least) of entries, there also will be additional delegates for the different columns etc. It's fairly complex and the building time for even plain model, without delegates, goes up to .3 sec, which makes the TreeView to freeze. Please advice me for the best approach on solving this. I was thing of somehow building the model in different thread, and eventually sending it to the TreeView, where it would just perform setModel() with the new one, but couldn't make that work. here is some code that may illustrate the problem a bit: from PyQt4.QtCore import * from PyQt4.QtGui import * import sys, os, re, time app = QApplication(sys.argv) REFRESH = 1 class Reloader_Thread(QThread): def __init__(self, parent = None): QThread.__init__(self, parent) self.loaders = ['\\', '--', '|', '/', '--'] self.emit(SIGNAL('refresh')) def run(self): format = '|%d/%b/%Y %H:%M:%S| ' while True: self.emit(SIGNAL('refresh')) self.sleep(REFRESH) class Model(QStandardItemModel): def __init__(self, viewer=None): QStandardItemModel.__init__(self,None) self.build() def build(self): stTime = time.clock() newRows = [] for r in range(1000): row = [] for c in range(12): item = QStandardItem('%s %02d%02d' % (time.strftime('%H"%M\'%S'), r,c)) row.append(item) newRows.append(row) eTime = time.clock() - stTime outStr = 'Build %03f' % eTime format = '|%d/%b/%Y %H:%M:%S| ' stTime = time.clock() self.beginRemoveRows(QModelIndex(), 0, self.rowCount()) self.removeRows(0, self.rowCount()) self.endRemoveRows() eTime = time.clock() - stTime outStr += ', Remove %03f' % eTime stTime = time.clock() numNew = len(newRows) for r in range(numNew): self.appendRow(newRows[r]) eTime = time.clock() - stTime outStr += ', Set %03f' % eTime self.emit(SIGNAL('status'), outStr) self.reset() w = QWidget() w.setGeometry(200,200,800,600) hb = QVBoxLayout(w) tv = QTreeView() tvm = Model(tv) tv.setModel(tvm) sb = QStatusBar() reloader = Reloader_Thread() tvm.connect(tvm, SIGNAL('status'), sb.showMessage) reloader.connect(reloader, SIGNAL('refresh'), tvm.build) reloader.start() hb.addWidget(tv) hb.addWidget(sb) w.show() app.setStyle('plastique') app.processEvents(QEventLoop.AllEvents) app.aboutToQuit.connect(reloader.quit) app.exec_()

• JConsole does not connect when a program (running in eclipse) is waiting for a console input

  - by Calm Storm

  Hi, I have a problem similar to the one mentioned here. I have a program which launches a selenium browser and refreshes it every 2 seconds. My idea here was to monitor the memory usage of my application as the page is being hit. This console program does a "System.in.read" and when a user presses enter key, this stops the browser refresh thread. I run the program and it runs as I would expect it to. But when I fire jconsole and attach it to the process, it looks like jconsole waits forever to attach. This is because of the "System.in.read", apparently as shown in the JConsole source. In my code it makes perfect sense for me to terminte the browser when user presses something so is there any alternative available at all ? (Posted code sample below) package com.ekanathk; import java.util.ArrayList; import java.util.List; import org.junit.Test; public class MultiThread { @Test public void testSimple() throws Exception { List<Integer> x = new ArrayList<Integer>(); for(int i = 0; i < 1000; i++) { x.add(i); } System.out.print("Press Enter to stop (try attach a jconsole now...."); System.in.read(); } } The problem here seems to be that any System.in.read (either in Main thread or any threads) seems to completely block jconsole. I guess the problem essentially boils down to multiple threads requesting system inputs at the same time? Is there a solution ? UPDATE 1: It seems this works fine when launching the class from a command line, however when I run from eclipse, jconsole cant connect. Any reasons ?

• Adding a font for use in ReportLab

  - by Jimmy McCarthy

  I'm trying to add a font to the python ReportLab so that I can use it for a function. The function is using canvas.Canvas to draw a bunch of text in a PDF, nothing complicated, but I need to add a fixed width font for layout issues. When I tried to register a font using what little info I could find, that seemed to work. But when I tried to call .addFont('fontname') from my Canvas object I keep getting "PDFDocument instance has no attribute 'addFont'" Is the function just not implemented? How do I get access to fonts other than the 10 or so default ones that are listed in .getAvailableFonts? Thanks. Some example code of what I'm trying to make happen: from reportlab.pdfgen import canvas c = canvas.Canvas('label.pdf') c.addFont('TestFont') #This throws the error listed above, regardless of what argument I use (whether it refers to a font or not). c.drawString(1,1,'test data here') c.showPage() c.save() To register the font, I tried from reportlab.lib.fonts import addMapping from reportlab.pdfbase import pdfmetrics pdfmetrics.registerFont(TTFont('TestFont', 'ghettomarquee.ttf')) addMapping('TestFont', 0, 0, 'TestFont') where 'ghettomarquee.ttf' was just a random font I had lying around.

• Print a string that contains a certain pattern in Java

  - by jjpotter

  I am trying to find a regular expression within a line of a .csv file, so I can eventually save all the matches to another file, and lose all the other junk. So a line in my file might look like: MachineName,User,IP,VariableData,Location The VariableData is what I want to match, and if there's a match, print the line. I am using a pattern for this because I only want 3 out of 10 of variations of VariableData, and out of those 3, they are numbered differently(example, "pc104, pccrt102, pccart65"). I am trying to do this using the Scanner Class and keeping it simple as possible so I can understand it. Here is where I was heading with this...(the pattern isn't complete, just have it like this for testing). import java.io.File; import java.util.Scanner; import java.util.regex.Pattern; public class pcv { public static void main(String[] args) { File myFile = new File("c:\\temp\\report.csv"); Pattern myPat = Pattern.compile("pc"); try{ Scanner myScan = new Scanner(myFile); while(myScan.hasNext()){ if(myScan.hasNext(myPat)){ System.out.println("Test"); } } }catch(Exception e){ } } } This code loops, im guessing the .hasNext() methods are resetting themselves. I've played around with the Matcher class a little bit, but only found a way to match the expression but not get the whole line. My other throught was maybe somehow count the line that contains the pattern, then go back and print the line that corresponds to the counts.

• HttpParsing for hypertext

  - by Nani

  I am in process of getting all hierarchical links from a given link and validating them; This is the code I wrote. But I am not feeling it as efficient. Reasons are: 1.For the non unique links which open same page, code is getting sub-links again and again 2.Is the code getting all links? 3.Is it making valid URLs from the sub-links it derived? 4.May be some other reasons about which I have no idea. Please suggest me how to make this piece of code efficient . Thank you. class Program { public static ArrayList sublink = new ArrayList(); public static ArrayList subtitle = new ArrayList(); public static int ini = 0, len_o, len_n, counter = 0; static void Main(string[] args) { // Address of URL string URL = "http://www.techonthenet.com/"; sublink.Add(URL); l: len_o = sublink.Count; len_o); Console.WriteLine("-------------Level:" + counter++); for (int i = ini; i < len_o; i++) test(sublink[i].ToString()); len_n = sublink.Count; if (len_o < len_n) { ini = len_o; goto l; } Console.ReadKey(); } //method to get the sub-links public static void test(string URL) { try { // Get HTML data WebClient client = new WebClient(); Stream data = client.OpenRead(URL); StreamReader reader = new StreamReader(data); string str = "", htmldata = "", temp; int n1, n2; str = reader.ReadLine(); while (str != null) { htmldata += str; str = reader.ReadLine(); } data.Close(); for (int i = 0; i < htmldata.Length - 5; i++) { if (htmldata.Substring(i, 5) == "href=") { n1 = htmldata.Substring(i + 6, htmldata.Length - (i + 6)).IndexOf("\""); temp = htmldata.Substring(i + 6, n1); if (temp.Length > 4 && temp.Substring(0, 4) != "http") { if(temp.Substring(0,1)!="/") temp=URL.Substring(0,URL.IndexOf(".com/")+5)+temp; else temp = URL.Substring(0, URL.IndexOf(".com/") + 5) + temp.Remove(0,1); } if (temp.Length < 4) temp = URL.Substring(0, URL.IndexOf(".com/") + 5) + temp; sublink.Add(temp); n2 = htmldata.Substring(i + n1 + 1, htmldata.Length - (i + n1 + 1)).IndexOf("<"); subtitle.Add(htmldata.Substring(i + 6 + n1 + 2, n2 - 7)); i += temp.Length + htmldata.Substring(i + 6 + n1 + 2, n2 - 7).Length; } } for (int i = len_n; i < sublink.Count; i++) Console.WriteLine(i + "--> " + sublink[i]); } catch (WebException exp) { Console.WriteLine("URL Could not be Resolved" + URL); Console.WriteLine(exp.Message, "Exception"); } } }

• ExternalInterface

  - by Jesse

  Hey, so I'm having a bunch of trouble getting ExternalInterface to work, which is odd, because I use it somewhat often. I'm hoping it's something I just missed because I've been looking at it too long. The flash_ready function is correctly returning the objectID, and as far as I can tell, everything else is in order. Unfortunately, when I run it, I get an error (varying by browser) telling me that basically document.getElementById(<movename>).test() is not a valid method. Here's the code: javascript: function flash_ready(i){ document.getElementById(i).test('success!'); } Embed Html (Generated): <script type="text/javascript"> swfobject.embedSWF("/chainmaille/includes/media/flash/upload_image.swf", "/chainmaille/includes/media/flash/upload_image", "500", "50", "9.0.0","expressInstall.swf", {}, {allowScriptAccess:'always', wmode:'transparent'},{id:'uploader_flash',name:'uploader_flash'}); </script> <object type="application/x-shockwave-flash" id="uploader_flash" name="uploader_flash" data="/chainmaille/includes/media/flash/upload_image.swf" width="500" height="50"><param name="allowScriptAccess" value="always"><param name="wmode" value="transparent"></object> AS3 : package com.jesseditson.uploader { import flash.display.MovieClip; import flash.external.ExternalInterface; import flash.system.Security; public class UI extends MovieClip { // Initialization: public function UI() { Security.allowDomain('*'); ExternalInterface.addCallback("test", test); var jscommand:String = "flash_ready('"+ExternalInterface.objectID+"');"; var url:URLRequest = new URLRequest("javascript:" + jscommand + " void(0);"); navigateToURL(url, "_self"); } public function test(t){ trace(t); } } } Swfobject is being included via google code, and the flash embeds just fine, so that's not the problem. I've got a very similar setup working on another server, but can't seem to get it working on this one. It's a Hostgator shared server. Could it be the server's fault? Anybody see any obvious syntax problems? Thanks in advance!

• Django-South introspection rule doesn't work.

  - by Ory Band

  I'm using Django 1.2.3 and South 0.7.3. I am trying to convert my app (named core) to use Django-South. I have a custom model/field that I'm using, named ImageWithThumbsField. It's basically just the ol' django.db.models.ImageField with some attributes such as height, weight, etc. While trying to ./manage.py convert_to_auth core I receieve South's freezing errors. I have no idea why, I'm Probably missing something... I am using a simple custom Model: from django.db.models import ImageField class ImageWithThumbsField(ImageField): def __init__(self, verbose_name=None, name=None, width_field=None, height_field=None, sizes=None, **kwargs): self.verbose_name=verbose_name self.name=name self.width_field=width_field self.height_field=height_field self.sizes = sizes super(ImageField, self).__init__(**kwargs) And this is my introspection rule, which I add to the top of my models.py: from south.modelsinspector import add_introspection_rules from lib.thumbs import ImageWithThumbsField add_introspection_rules( [ ( (ImageWithThumbsField, ), [], { "verbose_name": ["verbose_name", {"default": None}], "name": ["name", {"default": None}], "width_field": ["width_field", {"default": None}], "height_field": ["height_field", {"default": None}], "sizes": ["sizes", {"default": None}], }, ), ], ["^core/.fields/.ImageWithThumbsField",]) This is the errors I receieve: ! Cannot freeze field 'core.additionalmaterialphoto.photo' ! (this field has class lib.thumbs.ImageWithThumbsField) ! Cannot freeze field 'core.material.photo' ! (this field has class lib.thumbs.ImageWithThumbsField) ! Cannot freeze field 'core.material.formulaimage' ! (this field has class lib.thumbs.ImageWithThumbsField) ! South cannot introspect some fields; this is probably because they are custom ! fields. If they worked in 0.6 or below, this is because we have removed the ! models parser (it often broke things). ! To fix this, read http://south.aeracode.org/wiki/MyFieldsDontWork Does anybody know why? What am I doing wrong?

• Grails validation problems with sets of data: only getting one error message for all errors in a set

  - by Matt

  Hi, I'm trying to validate a domain class that has a number of subsets. class IebeUser { ... static hasMany = [openUserAnswers:OpenUserAnswer, closedUserAnswers:ClosedUserAnswer] } class OpenUserAnswer { OpenQuestion openQuestion String text static belongsTo = [user:IebeUser] static constraints = { openQuestion(nullable:false) text(blank:false) } } class ClosedUserAnswer { ClosedQuestion closedQuestion ClosedAnswer answer static belongsTo = [user:IebeUser] static constraints = { closedQuestion(nullable:false) answer(nullable:false) } } A closed question has a set of predefined answers and an open question lets the user enter a freeform answer. All is well until I come to validate the object after entry in a form: params: [closedUserAnswers[0].answer.id:, closedUserAnswers[0]:[answer:[id:], answer.id:], password:dfgdfgdf, openUserAnswers[0].text:gdfgdfgdfg, openUserAnswers[0]:[text:gdfgdfgdfg], _isOptedOut:, create:Continue, username:gdfgdfggdf, email:[email protected], closedUserAnswers[1].answer.id:, closedUserAnswers[1]:[answer:[id:], answer.id:], openUserAnswers[1].text:, openUserAnswers[1]:[text:], firstName:dfgdf, lastName:gdfgdfgd, action:save, controller:main] The key bits being: closedUserAnswers[0].answer.id:, closedUserAnswers[0]:[answer:[id:] closedUserAnswers[1].answer.id:, closedUserAnswers[1]:[answer:[id:] openUserAnswers[1].text:, openUserAnswers[1]:[text:] In my tests I have two objects of type closedUserAnswers and two of openUserAnswers. But when I call validation on IebeUser I only get validation errors for the closedUserAnswers or the openUserAnswers as a whole. I don't get validation errors for each object with a problem which is what I need. I really need an error per instance. Does anyone know what I'm doing wrong? Even when I call the validate method against each closedUserAnswer/openUserAnswer I still only get one per type. Here are my errors. Sorry for all the code, but thought I'd include as much of the code as possible so that it makes sense.
