问题 I'm trying to use distinct() with pagination() in laravel 5.2 with fluent and it's given result proper but pagination remain same(Like without apply distinct). I have already reviewed and tested below answers with mine code - laravel 5 - paginate total() of a query with distinct - Paginate & Distinct - Query Builder paginate method count number wrong when using distinct My code is something like: DB::table('myTable1 AS T1') ->select('T1.*') ->join('myTable2 AS T2','T2.T1_id','=','T1.id') -

问题 I am in the process of updating the existing *.hbm.xml files into fluent ClassMaps and have stumbled on a mistake in our mapping files, and I don't know the default behavior for me to map this correctly. The mapping file has: <one-to-one name="LineItemAssembly" class="LineItemAssembly" cascade="all-delete-orphan" /> When using Fluent, I would expect this to map to: HasOne<LineItemAssembly>(x => x.LineItemAssembly) .Cascade.AllDeleteOrphan(); However, AllDeleteOrphan() is not an option off of

问题 Hi I'm stuck with a problem. I want to implement the builder pattern to make creating my objects easier. The problem I face has to do with nested object. The object I would like to create has a list of other objects in it, and I don't really have an idea on how to tackle it. I want to be able to do the following (Simpler objects for example): Receipt RestaurantReceipt = new ReceiptBuilder() .withDate("value") .withName("value") .AddItem("value") .WithIngredients("value") .WithType("value")

问题 I am having a problem in Fluent NHibernate example utilizing the Many-to-Many relationships. I tried to find out examples on a similar case, and I found tons, but I'm still having the same problem. When running the test project, the following exception is thrown: NHibernate.PropertyAccessException: Exception occurred getter of project.Entities.User.UserName ---> System.Reflection.TargetException: Object does not match target type. This is an image of the tables: and the code public UsersMap()

问题 Given the following scenario, I want map the type hierarchy to the database schema using Fluent NHibernate. I am using NHibernate 2.0 Type Hierarchy public abstract class Item { public virtual int ItemId { get; set; } public virtual string ItemType { get; set; } public virtual string FieldA { get; set; } } public abstract class SubItem : Item { public virtual string FieldB { get; set; } } public class ConcreteItemX : SubItem { public virtual string FieldC { get; set; } } public class

问题 Foo foo = Foo.builder() .setColor(red) .setName("Fred") .setSize(42) .build(); So I know there is the following "Builder" solution for creating named parameters when calling a method. Although, this only seems to work with inner static classes as the builder or am I wrong? I had a look at some tutorials for builder pattern but they seem really complex for what im trying to do. Is there any way to keep the Foo class and Builder class separate while having the benefit of named parameters like

问题 How does one go about create an API that is fluent in nature? Is this using extension methods primarily? 回答1: This article explains it much better than I ever could. EDIT, can't squeeze this in a comment... there are two sides to interfaces, the implementation and the usage. There's more work to be done on the creation side, I agree with that , however the main benefits can be found on the usage side of things. Indeed, for me the main advantage of fluent interfaces is a more natural, easier

问题 I am trying to write a Fluent Interface API that can scale well. What structure would allow for strong types, inheritance, and state-full(as in the class type)? For instance class A { public A PerformFoo() { //do stuff return this; } } class B : A { } I would like class B when calling PerformFoo to return B not A, ideally I would prefer to stay away from public class B : A { public new B PerformFoo() { return (B)base.PerformFoo(); } } As to not have to override or new Every method in child

问题 Given this XML configuration (which works) <component type="X.Y.Z.ActivityService, X.Y.Z.Services" id="X.Y.Z.ActivityService" lifestyle="transient"> <parameters> <Listeners> <array> <item>${DefaultActivityListener}</item> </array> </Listeners> </parameters> </component> <component type="X.Y.Z.DefaultActivityListener, X.Y.Z.Services" id="DefaultActivityListener" lifestyle="transient" /> I have converted to use the fluent API as below (which doesn't work): Container.Register( Component.For<X.Y
