mapping

问题 I'm experimenting with knockout and the mapping plugin and wondering why this doesn't work. I have a viewmodel that I want to load using the mapping extension function todoListViewModel(data) { ko.mapping.fromJSON(data, { todos: TodoItem.options }, self); ko.mapping.fromJSON(data, { todos: TodoItem.options }, self); } the mapping has an options that looks like this: var TodoItem = function (options) { var todoItem = ko.mapping.fromJS(options.data); todoItem.remove = function () { alert(

问题 Goal: I wan´t to achieve a rule based Mapping between ontologies in order to fulfill a common task of data migration. Way to achieve the goal: To achieve this i developed a abstract data structure which is capable to store all information provided by the xml representation of any datatype. Then i wrote a parser, which constructs a ontology out of targeted document-type definition. Now when i read the data in it is first associated to the abstractDatatype namespace, lets call it aS .

问题 I'm using NHibernate and Fluent NHibernate to create a mapping file for a domain object (though I don't care if an answer uses fluent NHibernate or xml hbm syntax). And I'm having trouble with figuring out how I specify that a set of columns representing a component within the domain object is unique. Here's the domain object: public class SpaceLocation { public SpaceCoordinate Coordinates { get; set; } public SpaceObject AtLocation { get; set; } } and here is the component I'm having trouble

问题 I am trying to map a simple Oracle UDT in my c# application. When I try to extract data from DataReader , it throws the following exception: Custom type mapping for 'dataSource='DB' schemaName='C##LAZAR' typeName='MATICNIBROJ_T'' is not specified or is invalid Oracle UDT is: create or replace TYPE "MATICNIBROJ_T" AS OBJECT ( MaticniBroj NUMBER(13) ) INSTANTIABLE NOT FINAL Custom class used for mapping: [OracleCustomTypeMapping("C##LAZAR.MATICNIBROJ_T")] public class MaticniBrojT :

问题 Is it possible to join two classes without specified mapping between them (using Criteria API)? I must join two classes and retrieve data from both but I can't mapping them. I know only foreign key SomeID in the first class and primary key ID in second. How to create Criteria to join them? Is it possible without mapping? Please, help, I'm really need it but I'm stuck. :/ PS I know 'any' mapping but I have 10 fields like SomeID. Creating any mappings for 10 fields only for creating joins is

问题 I have a problem that could be boiled down to finding a way of mapping a triangular matrix to a vector skipping the diagonal. Basically I need to translate this C++ code using the Gecode libraries // implied constraints for (int k=0, i=0; i<n-1; i++) for (int j=i+1; j<n; j++, k++) rel(*this, d[k], IRT_GQ, (j-i)*(j-i+1)/2); Into this MiniZinc (functional) code constraint forall ( i in 1..m-1 , j in i+1..m ) ( (differences[?]) >= (floor(int2float(( j-i )*( j-i+1 )) / int2float(2)) )); And I

问题 I'm using spring annotation based controller. I want my URL /user/messages to map to some controller a if query parameter tag is present otherwise to some different controller b. This is required because when parameter tag is present then some more parameters can be present along with that which i want to handle in different controller to keep the implementation clean.Is there any way to do this in spring. Also is there any other elegant solution to this problem ? 回答1: If you want to go the

问题 I wonder if it's possible to define Set in Hibernate mapping in a such way, that element would specify not column in original ( FOO ) table, but in joined one ( BAR ). Let's say we have some FooContainer.hbm.xml , which contains Set of Foo objects: <set ...> <key column="COLUMN_FROM_BAR" /> <one-to-many class="xyz.Foo" /> </set> Here FOO has FK to BAR ( FOO.BAR_ID ), so joining is done through element in Foo.hbm.xml: <many-to-one class="xyz.Bar" fetch="join" column="BAR_ID" foreign-key="barId
