  • Wordpress databse insert() and update() - using NULL values

    - by pygorex1
    Wordpress ships with the wpdb class which handles CRUD operations. The two methods of this class that I'm interested in are the insert() (the C in CRUD) and update() (the U in CRUD). A problem arises when I want to insert a NULL into a mysql database column - the wpdb class escapes PHP null variables to empty strings. How can I tell Wordpress to use an actual MySQL NULL instead of a MySQL string?

  • Binary comparison operators on generic types

    - by Brian Triplett
    I have a generic class that takes a type T. Within this class I have a method were I need to compare a type T to another type T such as: public class MyClass<T> { public T MaxValue { // Implimentation for MaxValue } public T MyMethod(T argument) { if(argument > this.MaxValue) { // Then do something } } } The comparison operation inside of MyMethod fails with Compiler Error CS0019. Is it possible to add a constraint to T to make this work? I tried adding a where T: IComparable<T> to the class definition to no avail.

  • Django admin.py missing field error

    - by user782400
    When I include 'caption', I get an error saying EntryAdmin.fieldsets[1][1]['fields']' refers to field 'caption' that is missing from the form In the admin.py; I have imported the classes from joe.models import Entry,Image Is that because my class from models.py is not getting imported properly ? Need help in resolving this issue. Thanks. models.py class Image(models.Model): image = models.ImageField(upload_to='joe') caption = models.CharField(max_length=200) imageSrc = models.URLField(max_length=200) user = models.CharField(max_length=20) class Entry(models.Model): image = models.ForeignKey(Image) mimeType = models.CharField(max_length=20) name = models.CharField(max_length=200) password = models.URLField(max_length=50) admin.py class EntryAdmin(admin.ModelAdmin): fieldsets = [ ('File info', {'fields': ['name','password']}), ('Upload image', {'fields': ['image','caption']})] list_display = ('name', 'mimeType', 'password') admin.site.register(Entry, EntryAdmin) admin.site.register(Image)

  • Help understanding the Single Responsibility Principle

    - by user204588
    I'm trying to understand what a responsibility actually is so I want to use an example of something I'm currently working on. I have a app that imports product information from one system to another system. The user of the apps gets to choose various settings for which product fields in one system that want to use in the other system. So I have a class, say ProductImporter and it's responsibility is to import products. This class is large, probably too large. The methods in this class are complex and would be for example, getDescription. This method doesn't simply grab a description from the other system but sets a product description based on various settings set by the user. If I were to add a setting and a new way to get a description, this class could change. So, is that two responsibilities? Is there one that imports products and one that gets a description. It would seem this way, almost every method I have would be in it's own class and that seems like overkill. I really need a good description of this principle because it's hard for me to completely understand. I don't want needless complexity.

  • Logging exceptions during bean injection

    - by Marc W
    I think this is a pretty basic question, but after Googling around I can't seem to find the answer. What I need is a way to log some custom output with log4j during Spring bean construction. I have a factory class called ResponderFactory (being used as an instance factory in Spring) with a factory method that can throw 2 different types of exception. public CollectorResponder collectorResponder(String inputQueueName) throws ConfigurationException, BrokerConnectionException {} Now, normally I could wrap a call to this method in a try-catch block with 2 catch clauses to handle the logging situations for each of the exceptions. However, if I'm using Spring to inject this CollectorResponder, created with the factory, into another class I don't see how this is possible. <bean id="responderFactory" class="com.package.ResponderFactory"> <constructor-arg index="0" ref="basicDispatcher" /> <constructor-arg index="1" value="http://localhost:9000" /> </bean> <bean id="collectorResponder" class="com.package.CollectorResponder" factory-bean="responderFactory" factory-method="collectorResponder"> <constructor-arg value="collector.in" /> </bean> <bean id="collectorConsumer" class="com.package.CollectorConsumer"> <constructor-arg ref="collectorResponder" /> </bean> Again, I want to catch these exceptions when the collectorResponder bean is instantiated. Right now I'm dealing with this is CollectorConsumer when I instantiate using new CollectorResponder(...). Is there any way I can do this?

  • Variable field in a constraint annotation

    - by Javi
    Hello, I need to create a custom constraint annotation which can access the value of another field of my bean. I'll use this annotation to validate the field because it depends on the value of the other but the way I define it the compiler says "The value for annotation attribute" of my field "must be a constant expression". I've defined it in this way: @Target(ElementType.FIELD) @Retention(RetentionPolicy.RUNTIME) @Constraint(validatedBy=EqualsFieldValidator.class) @Documented public @interface EqualsField { public String field(); String message() default "{com.myCom.annotations.EqualsField.message}"; Class<?>[] groups() default {}; Class<? extends Payload>[] payload() default {}; } public class EqualsFieldValidator implements ConstraintValidator<EqualsField, String>{ private EqualsField equalsField; @Override public void initialize(EqualsField equalsField) { this.equalsField = equalsField; } @Override public boolean isValid(String thisField, ConstraintValidatorContext arg1) { //my validation } } and in my bean I want something like this: public class MyBean{ private String field1; @EqualsField(field=field1) private String field2; } Is there any way to define the annotation so the field value can be a variable? Thanks

  • Active Record two belongs_to calls or single table inheritance

    - by ethyreal
    In linking a sports event to two teams, at first this seemed to make sense: events - id:integer - integer:home_team_id - integer:away_team_id teams - integer:id - string:name However I am troubled by how I would link that up in the active record model: class Event belongs_to :home_team, :class_name => 'Team', :foreign_key => "home_team_id" belongs_to :away_team, :class_name => 'Team', :foreign_key => "away_team_id" end Is that the best solution? In an answer to a similar question I was pointed to single table inheritance, and then later found polymorphic associations. Neither of which seemed to fit this association. Perhaps I am looking at this wrong, but I see no need to subclass a team into home and away teams since the distinction is only in where the game is played. If I did go with single table inheritance I wouldn't want each team to belong_to an event so would this work? # app/models/event.rb class Event < ActiveRecord::Base belongs_to :home_team belongs_to :away_team end # app/models/team.rb class Team < ActiveRecord::Base has_many :teams end # app/models/home_team.rb class HomeTeam < Team end # app/models/away_team.rb class AwayTeam < Team end I thought also about a has_many through association but that seems two much as I will only ever need two teams, but those two teams don't belong to any one event. event_teams - integer:event_id - integer:team_id - boolean:is_home Is there a cleaner more semantic way for making these associations in active record? or is one of these solutions the best choice? Thanks

  • How to find specific/local files via CMake

    - by Andreas Romeyke
    Hello, I have a problem with a locally installed library. In my project there is the xmlrpc++0.7-library: myproject/ +-- xmlrpc++0.7/ +-- src/ I want that CMake fallbacks using the local xmlrpc++0.7 directory if not found otherwise. Two problems, the first one, find_path() or find_library() does not work with local dir. I used a workaround testing if variables processed by find_xxx() are empty or not. If empty I set them manually. The cmake generates the Makefile without errors now. But if I want to compile the project via make, the c++ compiler returns "error: XmlRpc.h: file not found". The file XmlRpc.h lies in myproject/xmlrpc++0.7/src and if I compile all them manually it works fine. Here is my CMakeLists.txt. I am very happy if anyone could me point to the right solution to use cmake under conditions described above. --- CMakeLists.txt --- project(webservice_tesseract) cmake_minimum_required(VERSION 2.6) set(CMAKE_INCLUDE_CURRENT_DIR ON) # find tesseract find_path(TESSERACT_INCLUDE_DIR tesseract/tesseractmain.h /opt/local/include /usr/local/include /usr/include ) find_library(TESSERACT_LIBRARY_DIR NAMES tesseract_main PATHS /opt/local/lib/ /usr/local/lib/ /usr/lib ) message(STATUS "looked for tesseract library.") message(STATUS "Include file detected: [${TESSERACT_INCLUDE_DIR}].") message(STATUS "Lib file detected: [${TESSERACT_LIBRARY_DIR}].") add_library(tesseract STATIC IMPORTED) set_property(TARGET tesseract PROPERTY IMPORTED_LOCATION ${TESSERACT_LIBRARY_DIR}/libtesseractmain.a ) #find xmlrpc++ message(STATUS "cmake home dir: [${CMAKE_HOME_DIRECTORY}].") set(LOCAL_XMLRPCPLUSPLUS ${CMAKE_HOME_DIRECTORY}/xmlrpc0.7++/) message(STATUS "xmlrpc++ local dir: [${LOCAL_XMLRPCPLUSPLUS}].") find_path(XMLRPCPLUSPLUS_INCLUDE_DIR XmlRpcServer.h ${LOCAL_XMLRPCPLUSPLUS}src /opt/local/include /usr/local/include /usr/include ) find_library(XMLRPCPLUSPLUS_LIBRARY_DIR NAMES XmlRpc PATHS ${LOCAL_XMLRPCPLUSPLUS} /opt/local/lib/ /usr/local/lib/ /usr/lib/ ) # next lines are an ugly workaround because cmake find_xxx() does not find local stuff if (XMLRPCPLUSPLUS_INCLUDE_DIR) else (XMLRPCPLUSPLUS_INCLUDE_DIR) set(XMLRPCPLUSPLUS_INCLUDE_DIR ${LOCAL_XMLRPCPLUSPLUS}src) endif (XMLRPCPLUSPLUS_INCLUDE_DIR) if (XMLRPCPLUSPLUS_LIBRARY_DIR) else (XMLRPCPLUSPLUS_LIBRARY_DIR) set(XMLRPCPLUSPLUS_LIBRARY_DIR ${LOCAL_XMLRPCPLUSPLUS}) endif (XMLRPCPLUSPLUS_LIBRARY_DIR) message(STATUS "looked for xmlrpc++ library.") message(STATUS "Include file detected: [${XMLRPCPLUSPLUS_INCLUDE_DIR}].") message(STATUS "Lib file detected: [${XMLRPCPLUSPLUS_LIBRARY_DIR}].") add_library(xmlrpc STATIC IMPORTED) set_property(TARGET xmlrpc PROPERTY IMPORTED_LOCATION ${XMLRPCPLUSPLUS_LIBRARY_DIR}/libXmlRpc.a ) #### link together include_directories(${XMLRPCPLUSPLUS_INCLUDE_DIR} ${TESSERACT_INCLUDE_DIR}) link_directories(${XMLRPCPLUSPLUS_LIBRARY_DIR} ${TESSERACT_LIBRARY_DIR}) add_library(simpleocr STATIC simple_ocr.cpp) add_executable(webservice_tesseract webservice.cpp) target_link_libraries(webservice_tesseract xmlrpc tesseract simpleocr)

  • Fancybox close button not showing when using different template

    - by VeraG
    I have a page where I need to use 2 different FancyBox styles for different elements on the page. To achieve that, I added tpl option and modified stylesheet accordingly. Here is what I have: $(document).ready(function() { $(".login").fancybox({ closeClick : false, closeBtn : true, tpl: { wrap : '<div class="fancybox-wrap1" tabIndex="-1"><div class="fancybox-skin1"><div class="fancybox-outer"><div class="fancybox-inner"></div></div></div></div>', closeBtn : '<a title="Close" class="fancybox-item fancybox-close" href="javascript:;"></a>' } }); }); In my CSS, I added new styles for .fancybox-wrap1 and .fancybox-skin1. Styles work great BUT on the FancyBox with modified template "close" button completly disappears! I tried both adding and deleting closeBtn from tpl but it doesn't seem to make any difference. I also have a demo here (eventually I will need different background-images for FancyBox, not just background-color, that's why I'm doing it). What am I doing wrong? Any help will be greatly appreciated!

  • Error in Jaclplus component

    - by Aruna
    Hi, I am working on Joomla 1.5 and our site is using the Bluehost server.Till March 9th, 2010 our site was working perfectly.And on March 10th,2010 , the following error was shown in the site as Warning: Unexpected character in input: '' (ASCII=28) state=1 in /home1/tcscoinc/public_html/tcsrnd/administrator/components/com_jaclplus/jac lplus.class.php on line 73 Parse error: syntax error, unexpected T_STRING in /home1/tcscoinc/public_html/tcsrnd/administrator/components/com_jaclplus/jac lplus.class.php on line 73 For time being, i have just renamed the file jaclplus.class.php to make the site to function. As we are using Jaclplus component and we have purchased the Jaclplus component from Byos Tech , i have checked in the membership details.And we found that our Membership has been expired on 03/10/2010 . I have asked them but they had replied that it may not be a problem on membership. Please anyone share what can be the reason for the error.I am not able to open that file(jaclplus.class.php) since its a binary file.

  • How can I stop sorl thumbnail from breaking with very long filenames?

    - by bitbutter
    I've noticed that when working with SORL thumbnail, sometimes a user will upload an image with a very long filename, longer than the varfield in the database can hold. The name gets truncated in the database and the project gives errors whenever the image is requested. Is there a smart and safe way to have django automatically truncate long filenames in sorl uploads (prior to saving them in the database) to prevent this sort of thing? As reference, here's how the relevant model from my current project looks: class ArtistImage(models.Model): artist = models.ForeignKey(Artist) position = models.IntegerField() image = ThumbnailField( thumbnail_tag='<span class="artistimagewrapper"><img class="artistimage" src="%(src)s" width="%(width)s" height="%(height)s"></span>', upload_to='uploaded_images/artistimages', size=(900,900), quality=100, options={'crop': 'center'}, extra_thumbnails={ 'small':{ 'size':(92,92), 'quality':100, 'options':{'crop': 'center'}, } } ) class Meta: ordering = ('image',) def __unicode__(self): return (u"%s" % self.image)

  • Getting proper indentation using XMLBuilder in a helper

    - by Robbie
    I'm attempting to use a view helper to create some dynamic links based on if you're logged in or not. What I want returned, for sake of easy code readability, is: <ul class="right"> <li><a href="#">Login</a></li> <li><a href="#">Register</a></li> </ul> In the view helper I have this Ruby code: def loginh xm = Builder::XmlMarkup.new(:indent=>2, :margin=>4) xm.ul("class" => "right") { xm.li('class' => 'text') { xm.text("test") } } end In the view, the line that calls login helper is already indented 4 levels. Because of this, the first line gets 'skewed', so in the view I have: <%= loginh %> Which results in: <ul class="right"> <li class="text"> <text>test</text> </li> </ul> You can see it works perfectly, except for the first line. It would appear that the first line is affected by the indent before <%= loginh % is called. I can easily remedy this by removing the indentation prior to <%= loginh % - but in essence I'd be sacrificing code readability for markup readability. Which isn't what I'm looking to do. Is there any way I could remove the beginning whitespace?

  • Both tab & hover triggered popups problem

  • Java invokeAndWait of C# Action Delegate

    - by ikurtz
    the issue i mentioned in this post is actually happening because of cross threading GUI issues (i hope). could you help me with Java version of action delegate please? in C# it is done as this inline: this.Invoke(new Action(delegate() {...})); how is this achived in Java? thank you. public class processChatMessage implements Observer { public void update(Observable o, Object obj) { System.out.println("class class class" + obj.getClass()); if (obj instanceof String){ String msg = (String)obj; formatChatHeader(chatHeader.Away, msg); jlStatusBar.setText("Message Received"); // Show chat form setVisibility(); } } } processChatMessage is invoked by a separate thread triggered by receiving new data from a remote node. and i think the error is being produced as it trying to update GUI controls. do you think this is the reason? i ask because im new to Java and C#, but this is what is going on i think. SOLUTION: public class processChatMessage implements Observer { public void update(Observable o, Object obj) { if (obj instanceof String){ final String msg = (String)obj; try { SwingUtilities.invokeAndWait(new Runnable( ) { public void run( ) { formatChatHeader(chatHeader.Away, msg); jlStatusBar.setText("Message Received"); setVisibility(); } }); } catch (InterruptedException e){ } catch (InvocationTargetException e){ } } } }

  • Implementing INotifyPropertyChanged with PostSharp 1.5

    - by no9
    Hello all. Im new to .NET and WPF so i hope i will ask the question correctly. I am using INotifyPropertyChanged implemented using PostSharp 1.5: [Serializable, DebuggerNonUserCode, AttributeUsage(AttributeTargets.Assembly | AttributeTargets.Class, AllowMultiple = false, Inherited = false), MulticastAttributeUsage(MulticastTargets.Class, AllowMultiple = false, Inheritance = MulticastInheritance.None, AllowExternalAssemblies = true)] public sealed class NotifyPropertyChangedAttribute : CompoundAspect { public int AspectPriority { get; set; } public override void ProvideAspects(object element, LaosReflectionAspectCollection collection) { Type targetType = (Type)element; collection.AddAspect(targetType, new PropertyChangedAspect { AspectPriority = AspectPriority }); foreach (var info in targetType.GetProperties(BindingFlags.Public | BindingFlags.Instance).Where(pi => pi.GetSetMethod() != null)) { collection.AddAspect(info.GetSetMethod(), new NotifyPropertyChangedAspect(info.Name) { AspectPriority = AspectPriority }); } } } [Serializable] internal sealed class PropertyChangedAspect : CompositionAspect { public override object CreateImplementationObject(InstanceBoundLaosEventArgs eventArgs) { return new PropertyChangedImpl(eventArgs.Instance); } public override Type GetPublicInterface(Type containerType) { return typeof(INotifyPropertyChanged); } public override CompositionAspectOptions GetOptions() { return CompositionAspectOptions.GenerateImplementationAccessor; } } [Serializable] internal sealed class NotifyPropertyChangedAspect : OnMethodBoundaryAspect { private readonly string _propertyName; public NotifyPropertyChangedAspect(string propertyName) { if (string.IsNullOrEmpty(propertyName)) throw new ArgumentNullException("propertyName"); _propertyName = propertyName; } public override void OnEntry(MethodExecutionEventArgs eventArgs) { var targetType = eventArgs.Instance.GetType(); var setSetMethod = targetType.GetProperty(_propertyName); if (setSetMethod == null) throw new AccessViolationException(); var oldValue = setSetMethod.GetValue(eventArgs.Instance, null); var newValue = eventArgs.GetReadOnlyArgumentArray()[0]; if (oldValue == newValue) eventArgs.FlowBehavior = FlowBehavior.Return; } public override void OnSuccess(MethodExecutionEventArgs eventArgs) { var instance = eventArgs.Instance as IComposed<INotifyPropertyChanged>; var imp = instance.GetImplementation(eventArgs.InstanceCredentials) as PropertyChangedImpl; imp.OnPropertyChanged(_propertyName); } } [Serializable] internal sealed class PropertyChangedImpl : INotifyPropertyChanged { private readonly object _instance; public PropertyChangedImpl(object instance) { if (instance == null) throw new ArgumentNullException("instance"); _instance = instance; } public event PropertyChangedEventHandler PropertyChanged; internal void OnPropertyChanged(string propertyName) { if (string.IsNullOrEmpty(propertyName)) throw new ArgumentNullException("propertyName"); var handler = PropertyChanged as PropertyChangedEventHandler; if (handler != null) handler(_instance, new PropertyChangedEventArgs(propertyName)); } } } Then i have a couple of classes (user and adress) that implement [NotifyPropertyChanged]. It works fine. But what i want would be that if the child object changes (in my example address) that the parent object gets notified (in my case user). Would it be possible to expand this code so it automaticly creates listeners on parent objects that listen for changes in its child objets?

  • subclassing and data contracts

    I'm playing with the following code: [ServiceContract] public interface IUserAccountService { [OperationContract] UserAccountResponse CreateNewUserAccount(UserAccountRequest userAccountRequest); } public abstract class BaseResponse { public bool Success { get; set; } public string Message { get; set; } } public class UserAccountResponse : BaseResponse { public int NewUserId { get; set; } } My questions are: Do I need to add the DataContract attribute to both the abstract class and the subclass? If the abstract class does not need the DataContract attribute, can I add the DataMember attribure to its properties?

  • C# 4.0: casting dynamic to static

    - by Kevin Won
    This is an offshoot question that's related to another I asked here. I'm splitting it off because it's really a sub-question: I'm having difficulties casting an object of type dynamic to another (known) static type. I have an ironPython script that is doing this: import clr clr.AddReference("System") from System import * def GetBclUri(): return Uri("http://google.com") note that it's simply newing up a BCL System.Uri type and returning it. So I know the static type of the returned object. now over in C# land, I'm newing up the script hosting stuff and calling this getter to return the Uri object: dynamic uri = scriptEngine.GetBclUri(); System.Uri u = uri as System.Uri; // casts the dynamic to static fine Works no problem. I now can use the strongly typed Uri object as if it was originally instantiated statically. however.... Now I want to define my own C# class that will be newed up in dynamic-land just like I did with the Uri. My simple C# class: namespace Entity { public class TestPy // stupid simple test class of my own { public string DoSomething(string something) { return something; } } } Now in Python, new up an object of this type and return it: sys.path.append(r'C:..path here...') clr.AddReferenceToFile("entity.dll") import Entity.TestPy def GetTest(): return Entity.TestPy(); // the C# class then in C# call the getter: dynamic test = scriptEngine.GetTest(); Entity.TestPy t = test as Entity.TestPy; // t==null!!! here, the cast does not work. Note that the 'test' object (dynamic) is valid--I can call the DoSomething()--it just won't cast to the known static type string s = test.DoSomething("asdf"); // dynamic object works fine so I'm perplexed. the BCL type System.Uri will cast from a dynamic type to the correct static one, but my own type won't. There's obviously something I'm not getting about this...

  • What does stdole.dll do?

    - by rc1
    We have a large C# (.net 2.0) app which uses our own C++ COM component and a 3rd party fingerprint scanner library also accessed via COM. We ran into an issue where in production some events from the fingerprint library do not get fired into the C# app, although events from our own C++ COM component fired and were received just fine. Using MSINFO32 to compare the loaded modules on a working system to those on a failing system we determined that this was caused by STDOLE.DLL not being in the GAC and hence not loaded into the faulty process. Dragging this file into the GAC caused events to come back fine from the fingerprint COM library. So what does stdole.dll do? It's 16k in size so it can't be much... is it some sort of link to another library like STDOLE32? How come its absence causes such odd behavior? How do we distribute stdole.dll? This is an XCOPY deploy app and we don't use the GAC. Should we package it as a resource and use the System.EnterpriseServices.Internal.Publish.GacInstall to ensure it's in the GAC?

  • What to pass to UserType, BlobType.setPreparedStatement session parameter

    - by dlots
    http://blog.xebia.com/2009/11/09/understanding-and-writing-hibernate-user-types/ I am attempting to defined a customer serialization UserType that mimics, the XStreamUserType referenced and provided here: http://code.google.com/p/aphillips/source/browse/commons-hibernate-usertype/trunk/src/main/java/com/qrmedia/commons/persistence/hibernate/usertype/XStreamableUserType.java My serializer outputs a bytearray that should presumably written to a Blob. I was going to do: public class CustomSerUserType extends DirtyCheckableUserType { protected SerA ser=F.g(SerA.class); public Class<Object> returnedClass() { return Object.class; } public int[] sqlTypes() { return new int[] {Types.BLOB}; } public Object nullSafeGet(ResultSet resultSet,String[] names,Object owner) throws HibernateException,SQLException { if() } public void nullSafeSet(PreparedStatement preparedStatement,Object value,int index) throws HibernateException,SQLException { BlobType.nullSafeSet(preparedStatement,ser.ser(value),index); } } Unfortunetly, the BlobType.nullSafeSet method requires the session. So how does one define a UserType that gets access to a servlet requests session? EDIT: There is a discussion of the issue here and it doesn't appear there is a solution: Best way to implement a Hibernate UserType after deprecations?

  • java.lang.ClassNotFoundException using google commons

    - by pie154
    I have two classes inside a package. Both call a method from another class, one works perfectly fine and the other gives the error java.lang.ClassNotFoundException and the error java.lang.NoClassDefFoundError: com/google/common/base/Predicate The class path should be the same for both as they are in he same package so I can't figure out why one has access to the class and the other doesn't? thanks in advance for any help given.

  • Accessing underlying managed object through a COM interface

    - by mfeingold
    I have a third party assembly with a public abstract class implementing a certain COM interface. Something to the effect of [ComVisible(true)] public abstract class SomeClass: ISomeInterface { .... public void Method1() {...} } The actual object is an internal object extending the SomeClass and is instantiated by the third party code Is there a way to access public methods of this class if all I have is the CCW to the ISomeInterface?
