wikimedia exposes a REST interface: https://wikimedia.org/api/rest_v1/#/
It looks like results are limited to 5k items with pagination. In such cases, you get a next value like the following:
Object {
items: Array(5000) [Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, …]
next: "AAAAJAAKMjAxNjAxMjUwNwAAEBOBQAAd0hGygICAgICAgIAAAAF2AH//7Hd//+x3"
}
The spec doesn't say anything about how to use it to get the next page. What should be the "next" call?
pun intended :)

I am trying to subsequently manipulate the menus and tabs of a w2ui application.
In order to implement a generic solution, I added an additional attribute (zndesktop) to the related elements. Now I am looking for a generic method which gives me an array of all objects having this attribute.
Of course, I can hardcode such a query. But I am asking if there is an generic approach (for example w2ui.objects) which would return an array of all UI objects created for the application (recursive search)
w2ui objects are actually stored directly in the global w2ui object using their name, until you destroy them.
Example: if you create a grid with
$('#grid').w2grid({
name: 'my_grid',
...
});
Then you can access it with w2ui.my_grid or w2ui['my_grid'].
Of course you can also iterate the w2ui object (or rather its properties) just like any other JS object.
While trying to assign an object to a view in my controller action I get the following message because this object is not persisted:
Could not serialize Domain Object Vendor\Extension\Domain\Model\Object. It is neither an Entity with identity properties set, nor a Value Object.
Is there any possibility to add this object to the view without creating a databaseentry?
The exception [InvalidArgumentValueException('Could not serialize Domain Object $className. It is neither an Entity with identity properties set, nor a Value Object.', 1260881688)][1] is thrown in the UriBuilder, thus when a model shall be used as argument for creating a link.
The instance of Vendor\Extension\Domain\Model\Object must either fulfill these requirements:
can be represented as array (is array or implements Iterator interface) OR
extends TYPO3\CMS\Extbase\DomainObject\AbstractDomainObject AND one of
extends TYPO3\CMS\Extbase\DomainObject\AbstractValueObject OR
having a valid uid, not null
Thus, if you instantiated the object directly in the controller, the uid property is not defined yet. This property is assigned if domain objects are fetched or added with a repository.
TypeConverters
TypeConverters allow to convert from a given identifier (some string representation, hash-value, ...) to a proper domain object. The following links show how to do that for the concept of an IBAN (International Bank Account Identifier).
IBAN model
TypeConverter to create object from string
TypeConverters have to registerd in ext_localconf.php like this:
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerTypeConverter(
\H4ck3r31\BankAccountExample\Domain\Property\TypeConverter\IbanTypeConverter::class
);
The Iban object can be used then in your controller:
public function someAction(Iban $iban) { ... }
Use array representation of your object
Another alternative could be to assign an array representation of the domain object to the view and use that to fill the link arguments:
$this->view->assign('myObject', $object->toArray());
When invoking a controller action, the object is reconstituted from the submitted array keys and are used as properties - thus array keys and properties must have the same naming, or a persistence column mapping is defined.
public function someAction(MyObject $object) { ... }
In my previously mentioned bank account example it looks like this:
BankDto model
Controller action invocation
The term "Dto" is the abbreviation for "Data Transfer Object", thus it's not a real domain entity, does not have a proper UID and is just used to encapsulate information in a domain object when passing that to different components.
What is the way to consume a list of custom objects inside another custom object in JAX-RS CXF implementation? As an example my object looks like below
#POST
#Produces({MediaType.APPLICATION_JSON})
#Path("test")
public Response myMethod(MyCustomObject myCustomObject) {
Inside MyCustomObject it has a list of another custom object which reside inside this as an inner class
public class MyCustomObject {
private List<MyInner> innerObjects;
public class MyInner {
private String property;
....
}
....
}
Request JSON object is passed as the POST body of the request. When I debug this I could get the MyCustomObject passed properly while I am sending the innerObjects list as null. But it seems its not picking this correctly when I have this array based structure there with a custom object. Additionally instead of this custom object array when I have a primitive type or a string based array the service works fine. How to deal with the above scenario.
It is probably because of the inner class.

Not sure what mapper you use (cxf default is jettison but it is all configurable), but the case is probably similar.
Great explanation here
non-static inner classes (including anonymous ones) have set of hidden variables added by compiler, passed via (hidden) constructor. And as a consequence, do not have zero-argument ("default") constructor
Briefly, I'm loading objects that descend from a base class using a repository defined against the base class. Although my objects are created with the correct descendant classes, any descendant classes that add navigation properties not present in the base class do not have those related objects loaded, and I have no way to explicitly request them.
Here is a simple method in a repository class that loads a given calendar event assuming you know its ID value:
public CalendarEvent GetEvent(int eventId)
{
using (var context = new CalendarEventDbContext(ConnectionString))
{
var result = (from evt in context.CalendarEvents
where eventId.Equals((int)evt.EventId)
select evt).ToList();
return result.ToList()[0];
}
}
CalendarEvent is a base class from which a large number of more specific classes descend. Entity Framework correctly determines the actual class of the calendar event specified by eventId and constructs and returns that derived class. This works perfectly.
Now, however, I have a descendant of CalendarEvent called ReportIssued. This object has a reference to another object called ReportRequest (another descendant of CalendarEvent, although I don't think that's important).
My problem is that when Entity Framework creates an instance of ReportIssued on my behalf I always want it to create and load the related instance of ReportRequested, but because I am creating the event in the context of generic calendar events, although I correctly get back a ReportIssued event, I cannot specify the .Include() to get the related object. I want to do it through this generically-expressed search because I won't necessarily know the type of eventId's event and also I have several other "Get" methods that return collections of CalendarEvent descendants.
I create my mappings using the Fluent API. I guess what I'm looking for is some way to express, in the mapping, that the related object is always wanted or, failing that, some kind of decorator that expresses the same concept.
I find it odd that when saving objects Entity Framework always walks the entire graph whereas it does not do the equivalent when loading objects.
I'm using a web service which returns results like the following example:
{
"name":"Frank",
"meals":[
"cheeseburger",
"lasagne"
]
}
My Core Data schema looks like this:
Using MagicalRecord's MR_importValuesForKeysWithObject method, how would I set about mapping the meals key to the related Meals.name attribute?
I can map the meals manually after, using a for in loop, but just wondered if there was a way MR_importValuesForKeysWithObject would perform this for me?
Basically I want each object in the JSON "meals" array to become a new Meals entity.
Override importMeals: on the Person object and do the lookup/create/associate manually.
(longer answer)
every property imported via MagicalRecord calls import(PropertyName) on the target object, by implementing it you can override functionality.
