  • Can I give a different id to define Cakephp model associations?

    - by gacrux
    I have an one to many association in which a Thing can have many Statuses defined as below: Status Model: class Status extends AppModel { var $name = 'Status'; var $belongsTo = array( 'Thing' => array( 'className' => 'Thing', 'foreignKey' => 'thing_id', ); } Thing Model: class Thing extends AppModel { var $name = 'Thing'; var $belongsTo = array( // other associations ); var $hasMany = array( 'Status' => array( 'className' => 'Status', 'foreignKey' => 'thing_id', 'dependent' => false, 'order' => 'datetime DESC', 'limit' => '10', ), // other associations ); } This works OK, but I would like Thing to use a different id to connect to Status. E.g. Thing would use 'id' for all of it's other associations but use 'thing_status_id' for it's Status association. How can I best do this?

  • can't increment Glib::ustring::iterator (getting "invalid lvalue in increment" compiler error)

    - by davka
    in the following code: int utf8len(char* s, int len) { Glib::ustring::iterator p( string::iterator(s) ); Glib::ustring::iterator e ( string::iterator(s+len) ); int i=0; for (; p != e; p++) // ERROR HERE! i++; return i; } I get the compiler error on the for line, which is sometimes "invalid lvalue in increment", and sometimes "ISO C++ forbids incrementing a pointer of type etc... ". Yet, the follwing code: int utf8len(char* s) { Glib::ustring us(s); int i=0; for (Glib::ustring::iterator p = us.begin(); p != us.end(); p++) i++; return i; } compiles and works fine. according the Glib::ustring documentation and the include file, ustring iterator can be constructed from std::string iterator, and has operator++() defined. Weird? BONUS QUESTION :) Is there a difference in C++ between the 2 ways of defining a variable: classname ob1( initval ); classname ob1 = initval; I believed that they are synonymous; yet, if I change Glib::ustring::iterator p( string::iterator(s) ); to Glib::ustring::iterator p = string::iterator(s); I get a compiler error (gcc 4.1.2) conversion from ‘__gnu_cxx::__normal_iterator, std::allocator ’ to non-scalar type ‘Glib::ustring_Iterator<__gnu_cxx::__normal_iterator, std::allocator ’ requesed thanks a lot!

  • Return an Oracle Associative Array from a function

    - by Paul Johnson
    Does anybody know if it is possible to return an associative array as the result of an Oracle function, if so do you have any examples? I have an Oracle package which contains an associative array declaration as defined below: TYPE EVENTPARAM IS TABLE OF NUMBER INDEX BY BINARY_INTEGER; This is then used in a stored procedure outside the package as follows: v_CompParams areva_interface.eventparam; The intention is to store an associative array of strings in the variable v_CompParams, returned from a Parse function in another package. The definition for which is as follows: PACKAGE STRING_MANIP IS TYPE a_array IS TABLE OF NUMBER INDEX BY BINARY_INTEGER; FUNCTION Parse (v_string VARCHAR2, v_delim VARCHAR2) RETURN a_array; FUNCTION RowCount(colln IN a_array) RETURN NUMBER; END; The code which implements this is: v_CompParams := STRING_MANIP.PARSE(v_CompID,v_Delim); Unfortunately it doesn't work, I get the error 'PLS-00382: expression is of wrong type'. I foolishly assumed, that since a_array derives from the same source Oracle type as the variable v_CompParams, that there would be no problem casting between them. Any help much appreciated. Kind Regards Paul J.

  • How do I stop ValueConverters from firing when swapping the content of a ContentControl

    - by DanM
    I thought what I was doing was right out of the Josh Smith MVVM handbook, but I seem to be having a lot of problems with value converters firing when no data in the view-model has changed. So, I have a ContentControl defined in XAML like this: <ContentControl Grid.Row="0" Content="{Binding CurrentViewModel}" /> The Window containing this ContentControl references a resource dictionary that looks something like this: <ResourceDictionary ...> <DataTemplate DataType="{x:Type lib_vm:SetupPanelViewModel}"> <lib_v:SetupPanel /> </DataTemplate> <DataTemplate DataType="{x:Type lib_vm:InstructionsPanelViewModel}"> <lib_v:InstructionsPanel /> </DataTemplate> </ResourceDictionary> So, basically, the two data templates specify which view to show with which view-model. This switches the views as expected whenever the CurrentViewModel property on my window's view-model changes, but it also seems to cause value converters on the views to fire even when no data has changed. It's a particular problem with IMultiValueConverter classes, because the values in the value array get set to DependencyProperty.UnsetValue, which causes exceptions unless I specifically check for that. But I'm getting other weird side effects too. This has me wondering if I shouldn't just do everything manually, like this: Instantiate each view. Set the DataContext of each view to the appropriate view-model. Give the ContentControl a name and make it public. Handle the PropertyChanged event for the window. In the event handler, manually set the Content property of the ContentControl to the appropriate view, based the CurrentViewModel (using if statements). This seems to work, but it also seems very inelegant. I'm hoping there's a better way. Could you please advise me the best way to handle view switching so that value converters don't fire unnecessarily?

  • XML problem in the basic menu example

    - by arakn0
    Hi there, I am trying to create an app with some menus, an I am following the basic example available in the official android site: http://developer.android.com/guide/topics/ui/menus.html My problems appear when I define the menu in the XML. After creating the folder res/menu and creating the menu_option.xml file from eclipse.... The project (in general) gives an error that can be read from the Problems tab: Unparsed aapt error(s)! Check the console for output Android Packaging Problem So, changing to the Console tab to get more information about the problem, this can be read: [2010-06-02 11:35:54 - TestAudio] Error in an XML file: aborting build. [2010-06-02 11:35:54 - TestAudio] W/ResourceType(11566): Bad XML block: header size 63327 or total size -144759824 is larger than data size 0 [2010-06-02 11:35:54 - TestAudio] /home/User/workspace/TestAudio/res/menu/options_menu.xml:1: error: Error parsing XML: no element found The strange thing is that eclipse recognizes the menu items that I've defined in the XML,I can reference them in the code with no problems and my main activity builds. (and the rest of the files too). Could it be that when eclipse creates a file, for some reason, the Android SDK has problems to read it, or something similar?? The XML code is exactly the same as the one in the example, so I don't really know what is happening. The code in options_menu.xml is this: <menu xmlns:android="http://schemas.android.com/apk/res/android" <item android:id="@+id/new_game" android:title="New Game" / <item android:id="@+id/quit" android:title="Quit" / </menu Thanks in advance for your help!

  • Problem resizing loader after loading swf

    - by DanK
    I'm using the following code to load an swf in a pure actionscript project (Flex Builder 3) _loader = new Loader(); _loader.contentLoaderInfo.addEventListener(Event.COMPLETE, Loader_Complete); _loader.contentLoaderInfo.addEventListener(Event.INIT, Loader_Init); var request:URLRequest = new URLRequest("Skins/TestSkin.swf"); _loader.load(request); this.addChild(_loader); This works okay and displays the swf on the stage (500x375 for some reason - not sure why, TestSkin.swf is a flex app with no defined width and height) However, when I try to scale the swf so that it will fill the stage, I have problems. I have tried: Setting _loader.width and _loader.height in my Loader_Complete handler Setting _loader.width and _loader.height in my Loader_Init handler Setting _loader.content.width and loader.content.height in my Loader_Complete handler Setting _loader.content.width and loader.content.height in my Loader_Init handler I have seen examples online where people say these work for them but whenever I set width or height in any of these ways, the loaded swf is simply not displayed at all. Any idea what could be causing this? What is the correct way to resize an swf that has been loaded with a Loader object?

  • Embedded Jetty resourceBase classpath URL

    - by drewzilla
    I'm embedding Jetty in a Spring based application. I configure my Jetty server in a Spring context file. The specific part of the configuration I'm having trouble with is this: <bean class="org.eclipse.jetty.webapp.WebAppContext"> <property name="contextPath" value="/" /> <property name="resourceBase" value="????????" /> <property name="parentLoaderPriority" value="true" /> </bean> If you see above, where I've put the ????????, I ideally want the resourceBase to reference a folder on my classpath. I'm deploying my application in a single executable JAR file and have a folder config/web/WEB-INF on my classpath. Jetty seems to be able to handle URLs defined in the resourceBase (e.g. jar:file:/myapp.jar!/config/web) but it doesn't seem to support classpath URLs. I get an IllegalArgumentException if I define something like classpath:config/web. This is a real pain for me. Does anyone know of anyway to achieve this functionality? Thanks, Andrew

  • Runtime Exception when using Custom Healthmonitoring event in medium trust

    - by Elementenfresser
    Hi, I'm using custom healthmonitoring events in ASP.NET We recently moved to a new server with default High Trust Permissions. Literature says that healthmonitoring and custom events should work under Medium or higher trust (http://msdn.microsoft.com/en-us/library/bb398933.aspx). Problem is it doesn't. In less than high trust I get a SecurityException saying The application attempted to perform an operation not allowed by the security policy It works in Full trust or when I remove the inheritance of System.Web.Management.WebErrorEvent. Any suggestions anyone? Here is the super simple code behind with a custom event defined: public partial class Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { try { CallCustomEvent(); } catch (Exception ex) { Response.Write(ex.Message); throw ex; } } /// <summary> /// this metho is never called due to lacking permissions... /// </summary> private void CallCustomEvent() { try { //do something useful here } catch (Exception) { //code to instantiate the forbidden inheritance...

  • Subsonic, child records, and collections

    - by Dane
    Hi, I've been working with subsonic for a few weeks now, and it is working really well. However, I've just run into an issue with child objects with additional partial properties. Some of it is probably me just not understanding the .Net object lifecycle. I have an object - search. This has a few properties like permissions and stuff, and it links to a child table called search_options. In my Asp.Net app, it loops through these search options and creates controls. Then on postback, it grabs the values and assigns it back to a "value" property on the search_option. This value property is a simple string that's defined in a partial class. I then want to create a method on the search object, called PerformSearch. This then loops through the child search_options, and performs a custom query based on the "value" property. However, even though I assign the "value" property to the child search_option, when I access it later via the search.search_options collection, it is null. I'm guessing that maybe because it's accessing it in two different places, it performs another lazy load from the DB and the value is lost? Is there a way to tell the class that it's already loaded or something? or a way to access it so it's not reloaded from the DB? Code is below (shitty pseudocode, not full version) : ASP.Net page, loading back the values from postback : dim obj_search as search = new subsonic.query.select().......' retrieves the search object for each opt as search_option in obj_search.search_options opt.Value = Ctype(FindControl("search_option_" + opt.search_option_id),Textbox).Text debug.print(opt.Value) ' value is correct next for each opt as search_option in obj_search.search_options debug.print(opt.Value) 'this is nothing next Now, the partial class : public partial class search_option private m_value as string public property Value() as string get return m_value end get set( byval value as string) m_value = value end set end property end class

  • Strings exported from a module have changed line breaks

    - by Jesse Millikan
    In a DrScheme project, I'm using a MrEd editor-canvas% with text% and inserting a string from a literal in a Scheme file. This results in an extra blank line in the editor for each line of text I'm trying to insert. I've tracked this down to the apparent fact that string literals from outside modules are getting extra line breaks. Here's a full example. The editor is irrelevant at this point, but it displays the result. ; test-literals.ss (module test-literals scheme (provide (all-defined-out)) (define exported-string "From another module with some more line breaks. ")) ; editor-test.ss (module editor-test scheme (require mred "test-literals.ss") (define w (instantiate frame% ("Editor Test" #f) )) (define c (instantiate editor-canvas% (w) (line-count 12) (min-width 400))) (define editor (instantiate text% ())) (send c set-editor editor) (send w show #t) (send editor erase) (send editor insert "Some text with some line breaks. ") (send editor insert exported-string)) And the result in the editor is Some text with some line breaks. From another module with some more line breaks. I've traced in and figured out that it's changing Unix line breaks to Windows line breaks when strings are imported from another module, but these display as double line breaks. Why is this happening and is there a way to stop it other than changing every imported string?

  • iPhone: Using a NSMutableArry in the AppDelegate as a Global Variable

    - by aahrens
    What i'm trying to accomplish is to have an NSMutableArray defined in the AppDelegate. I then have two UIViewControllers. One view is responsible for displaying the array from the AppDelegate. The other view is used to add items to the array. So the array starts out to be empty. View1 doesn't display anything because the array is empty. The User goes to View2 and adds an item to the array in AppDelegate. Then when the user goes back to View1 it now displays one item. Here is how I'm trying to accomplish this @interface CalcAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; UITabBarController *tabBarController; NSMutableArray *globalClasses; } @property (nonatomic,retain) NSMutableArray *globalClasses; My other view In the viewDidload I set the array in my View to be the one in the AppDelegate. In an effort to retain values. allCourses = [[NSMutableArray alloc]init]; CalcAppDelegate *appDelegate = (CalcAppDelegate *)[[UIApplication sharedApplication] delegate]; allCourses = appDelegate.globalClasses; Then I would update my allCourses array by adding a new item. Then try to set the array in the AppDelegate to be equal to the modified one. CalcAppDelegate *appDel = (CalcAppDelegate *)[[UIApplication sharedApplication] delegate]; NSLog(@"Size before reset %d",[appDel.globalClasses count]); appDel.globalClasses = allCourses; NSLog(@"Size after reset %d",[appDel.globalClasses count]); What I'm seeing that's returned is 2 in the before, and 2 after. So it doesn't appear to be getting updated properly. Any suggestions?

  • Django internationalization for admin pages - translate model name and attributes

    - by geekQ
    Django's internationalization is very nice (gettext based, LocaleMiddleware), but what is the proper way to translate the model name and the attributes for admin pages? I did not find anything about this in the documentation: http://docs.djangoproject.com/en/dev/topics/i18n/internationalization/ http://www.djangobook.com/en/2.0/chapter19/ I would like to have "???????? ????? ??? ?????????" instead of "???????? order ??? ?????????". Note, the 'order' is not translated. First, I defined a model, activated USE_I18N = True in settings.py, run django-admin makemessages -l ru. No entries are created by default for model names and attributes. Grepping in the Django source code I found: $ ack "Select %s to change" contrib/admin/views/main.py 70: self.title = (self.is_popup and ugettext('Select %s') % force_unicode(self.opts.verbose_name) or ugettext('Select %s to change') % force_unicode(self.opts.verbose_name)) So the verbose_name meta property seems to play some role here. Tried to use it: class Order(models.Model): subject = models.CharField(max_length=150) description = models.TextField() class Meta: verbose_name = _('order') Now the updated po file contains msgid 'order' that can be translated. So I put the translation in. Unfortunately running the admin pages show the same mix of "???????? order ??? ?????????". I'm currently using Django 1.1.1. Could somebody point me to the relevant documentation? Because google can not. ;-) In the mean time I'll dig deeper into the django source code...

  • How do I pass parameters between request-scoped beans

    - by smayers81
    This is a question that has been bothering me for sometime. My application uses ICEFaces for our UI framework and Spring 2.5 for Dependency Injection. In addition, Spring actually maintains all of our backing beans, not the ICEFaces framework, so our faces-config is basically empty. Navigation is not even really handled through navigation-rules. We perform manual redirects to new windows using window.open. All of our beans are defined in our appContext file as being request-scoped. I have Page ABC which is backed by BackingBeanABC. Inside that backing bean, I have a parameter say: private Order order; I then have Page XYZ backed by BackingBeanXYZ. When I redirect from page ABC to page XYZ, I want to transfer the 'order' property from ABC to XYZ. The problem is since everything is request-scoped and I'm performing a redirect, I am losing the value of 'description'. There has got to be an easier way to pass objects between beans in request scope during a redirect. Can anyone assist with this issue?

  • Webpage shared with like button not showing in users timeline

    - by einar
    I have a single pages and a one page that lists all of the single pages. On the overview page you can like each single page with their url. And of corse you can do the same when you are viewing a single page. My issue is very strange. Most of the pages that I would like show up on my timeline. But then there are some that don't show after I click like, not even if I click on "Post to Facebook". This page will not show in a users timeline if liked ore "Post'ed to Facebook". http://www.inspiredbyiceland.com/inspiration/iceland-airwaves/valdimar/ But this one will http://www.inspiredbyiceland.com/inspiration/iceland-airwaves/snorri-helgason/ But these pages are excls the same, they use the same template so the code should not be any different, and in fact I cant see any differents between these pages that could be causing this kind of problem. You can view the overview page here http://www.inspiredbyiceland.com/inspiration/iceland-airwaves/ . Most of the single pages work fine and show up on users timeline. Most of the content on the site works fine so far as I know. There is an Facebook application defined on the page. I'm not sure if that is related to this problem.

  • Can Core Data be used for objects with variable schemas?

    - by glenc
    I'm implementing a new iPhone app and am relatively new to Cocoa development overall. I am at the stage of choosing how the persistence layer of this app will work, and it looks like I'm basically choosing between Core Data and sqlite3. The persisted models in this app are intended to have a schema that is loaded at runtime (from some kind of defn file, probably XML). By which I mean, this app is intended to have objects that are user-definable to some extent, e.g. the Customer type (which has certain built-in fields like "name" and "email") can be modified to have extra fields based on the user's specific needs (e.g. a user might want to add a "favourite fruit" field to their Customer type). Having said that, will Core Data work for an app with a non-baked-in data model like this? I've just started playing around with the Core Data object designer thing in XCode and it seems like this thing wants to work with objects that have fixed fields that are compiled in. I'm definitely trying to take the path of least resistance here, and I can see the benefits of using an Apple-supplied data framework, but don't want to start down that path if it's going to lock me into a data model that's defined at compile time.

  • How do I find Microsoft APIs?

    - by Stephen
    I'm a java programmer, and if I see something that: I don't know about or just want to find a method description without opening an ide or am on support I type java [classname] into google, and there it is. If I try this crazy stunt for C# I'll come up with a whole heap of tutorials (how do I use it etc). If I manage to get to MSDN, I have to wade through a page describing every .net technology to see how their syntax references the same object, and then I have to find the appropriate page from there ([class name] Constructor) for example. This is even more pronounced, because I don't have Visual Studio, so I've got nothing to make it easier. There must be something I'm missing or don't know... how does this situation work for Microsoft developers? how can I make my life easier/searches better? are there techniques that work no matter what computer I'm on (e.g. require no computer setup/downloads) Notes It could be thought that java is just "java", but it's just that the java apis are only referenced/defined in the core language. For all the other languages on the JVM, it's assumed that you will just learn the correct syntax to use the java apis. I presume that .Net only lists a whole heap of languages as the api classes are actually different and have different interfaces capabilities (or some approximation of this presumption). Edit While searching msdn works... in the java space I can type 'java [anyclass]' and it will generally be found... whether it's a java core api or a third party library

  • If the address of a function can not be resolved during deduction, is it SFINAE or a compiler error?

    - by Faisal Vali
    In C++0x SFINAE rules have been simplified such that any invalid expression or type that occurs in the "immediate context" of deduction does not result in a compiler error but rather in deduction failure (SFINAE). My question is this: If I take the address of an overloaded function and it can not be resolved, is that failure in the immediate-context of deduction? (i.e is it a hard error or SFINAE if it can not be resolved)? Here is some sample code: struct X { // template T* foo(T,T); // lets not over-complicate things for now void foo(char); void foo(int); }; template struct S { template struct size_map { typedef int type; }; // here is where we take the address of a possibly overloaded function template void f(T, typename size_map::type* = 0); void f(...); }; int main() { S s; // should this cause a compiler error because 'auto T = &X::foo' is invalid? s.f(3); } Gcc 4.5 states that this is a compiler error, and clang spits out an assertion violation. Here are some more related questions of interest: Does the FCD-C++0x clearly specify what should happen here? Are the compilers wrong in rejecting this code? Does the "immediate-context" of deduction need to be defined a little better? Thanks!

  • Fabric "TypeError: not all arguments converted during string formatting"

    - by Brian Carpio
    I have the following fabric task: @task def deploy_west_ec2_ami(name, puppetClass, size='m1.small', region='us-west-1', basedn='joe', ldap='arch-ldap-01', secret='secret', subnet='subnet-d43b8ab d', sgroup='sg-926578fe'): execute(deploy_ec2_ami, name='%s',puppetClass='%s',size='%s',region='%s',basedn='%s',ldap='%s',secret='%s',subnet='%s',sgroup='%s' %(name, puppetClass , size, region, basedn, ldap, secret, subnet, sgroup)) However when I run the command: fab deploy_west_ec2_ami:test,java I get the following Traceback: Traceback (most recent call last): File "/usr/local/lib/python2.6/dist-packages/fabric/main.py", line 710, in main *args, **kwargs File "/usr/local/lib/python2.6/dist-packages/fabric/tasks.py", line 321, in execute results['<local-only>'] = task.run(*args, **new_kwargs) File "/usr/local/lib/python2.6/dist-packages/fabric/tasks.py", line 113, in run return self.wrapped(*args, **kwargs) File "/home/bcarpio/Projects/githubenterprise/awsdeploy/fabfile.py", line 35, in deploy_west_ec2_ami execute(deploy_ec2_ami, name='%s',puppetClass='%s',size='%s',region='%s',basedn='%s',ldap='%s',secret='%s',subnet='%s',sgroup='%s' %(name, puppetClass, size, region, basedn, ldap, secret, subnet, sgroup)) TypeError: not all arguments converted during string formatting I am not sure I understand why. I am pretty sure I have all the values defined here just fine. Also when I run the execute task deploy_ec2_ami as so: deploy_ec2_ami:test,java,m1.small,us-west-1,'dc\=test\,dc\=net',ldap-01,secret,subnet-d43b8abd,sg-926578fe It works just fine

  • Why aren't my objects sorting with sortedArrayUsingDescriptors?

    - by clozach
    I expected the code below to return the objects in imageSet as a sorted array. Instead, there's no difference in the ordering before and after. NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"imageID" ascending:YES]; NSSet *imageSet = collection.images; for (CBImage *image in imageSet) { NSLog(@"imageID in Set: %@",image.imageID); } NSArray *imageArray = [[imageSet allObjects] sortedArrayUsingDescriptors:(descriptor, nil)]; [descriptor release]; for (CBImage *image in imageArray) { NSLog(@"imageID in Array: %@",image.imageID); } Fwiw, CBImage is defined in my core data model. I don't know why sorting on managed objects would work any differently than on "regular" objects, but maybe it matters. As proof that @"imageID" should work as the key for the descriptor, here's what the two log loops above output for one of the sets I'm iterating through: 2010-05-05 00:49:52.876 Cover Browser[38678:207] imageID in Array: 360339 2010-05-05 00:49:52.876 Cover Browser[38678:207] imageID in Array: 360337 2010-05-05 00:49:52.877 Cover Browser[38678:207] imageID in Array: 360338 2010-05-05 00:49:52.878 Cover Browser[38678:207] imageID in Array: 360336 2010-05-05 00:49:52.879 Cover Browser[38678:207] imageID in Array: 360335 ... For extra credit, I'd love to get a general solution to troubleshooting NSSortDescriptor troubles (esp. if it also applies to troubleshooting NSPredicate). The functionality of these things seems totally opaque to me and consequently debugging takes forever.
