I have 2 classes as like below
public class A
{
public string Name { get; set;}
}
public class B : A
{
public string Description { get; set;}
}
With the following fluent validators
public class AValidator : AbstractValidator<A>
{
public A()
{
RuleFor(x => x.Name).NotEmpty();
}
}
public class BValidator : AbstractValidator<B>
{
public B(IValidator<AValidator> aValidator)
{
Include(aValidator);
RuleFor(x => x.Description).NotEmpty();
}
}
I'm using StrctureMap for IOC and xUnit for unit tests. Is there any way that I can validate / verify that Include has been setup in the BValidator?

How to use FluentValidation.AspNetCore and FluentValidation.MVC6 to validate Entities in AspNetCore , can anyone give me an example ?
This is working for me:
project.json add:
"FluentValidation.AspNetCore": "6.4.0-beta3"
startup.cs
services
.AddMvc()
.AddFluentValidation(fv => fv.RegisterValidatorsFromAssemblyContaining<Startup>());
Validation:
public class Foo
{
public string Bar {get; set;}
}
public class FooValidator : AbstractValidator<Foo>
{
public FooValidator()
{
RuleFor(x => x.Bar).NotEmpty().WithMessage("Error Message");
}
}
first you need to add nuget Install-Package FluentValidation.AspNetCore
you can have an action filter which will handle validation:
public class ValidatorActionFilter : IActionFilter
{
public void OnActionExecuting(ActionExecutingContext filterContext)
{
if (!filterContext.ModelState.IsValid)
{
filterContext.Result = new BadRequestObjectResult(filterContext.ModelState);
}
}
public void OnActionExecuted(ActionExecutedContext filterContext)
{
}
}
Startup.ConfigureServices looks like this to add auto validation and add FluentValidation:
services.AddMvc(opt =>
{
opt.Filters.Add(typeof(ValidatorActionFilter));
}).AddFluentValidation(fvc =>
fvc.RegisterValidatorsFromAssemblyContaining<Startup>())
If you need to read another assembly, name one of its classes instead of startUp
Now you can add a validation to ensure:
public class CreateCustomer
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
}
public class CreateCustomerValidator : AbstractValidator<CreateCustomer>
{
public CreateCustomerValidator()
{
RuleFor(x => x.FirstName).NotNull().WithMessage(Resource.Validaton.FirstNameRequired);
RuleFor(x => x.LastName).NotNull().WithMessage(Resource.Validaton.LastNameRequired);
RuleFor(x => x.Email).Matches(#"\A(?:[a-z0-9!#$%&'*=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*=?^_`{|}~-]+)*#(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?)\Z").WithMessage(Resource.Validaton.EmailFormat);
}
}
i'm trying to apply LAYERS Concept on demo project developed using mvc and entity framework both
Data Annotations : for validations in Data Access Layer and
Fluent API : for mapping and tables relations
Problem : DbContext didn't Create DB and there is a Runtime Exception :
The type 'Domain.DataLayer.Member' was not mapped. Check that the type has not been explicitly excluded by using the Ignore method or NotMappedAttribute data annotation. Verify that the type was defined as a class, is not primitive, nested or generic, and does not inherit from EntityObject.
Code : my solutions consists of :
1- class library (Domain.Classes project): where i wrote all of my classes
public class Member
{
public int Id { get; set; }
public string UserName { get; set; }
public string Password { get; set; }
public string FullName { get; set; }
}
2- DAL (Domain.DataLayer project): also another class library and i referenced domain.classes
namespace Domain.DataLayer.Repositories
{
[MetadataType(typeof(MemberMetadata))]
public partial class Member : Classes.Member , IValidatableObject
{
public Member()
{
Tasks = new HashSet<Task>();
History = new HashSet<Commint>();
}
public string ConfirmPassword { get; set; }
public HashSet<Task> Tasks { get; set; }
public HashSet<Commint> History { get; set; }
public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
var result = new List<ValidationResult>();
if (!string.Equals(Password,ConfirmPassword))
{
result.Add(new ValidationResult("mismatch pwsd", new[] {"ConfirmPassword" }));
}
return result;
}
}
}
and i used repository pattern :
public class MemberRepository : IRepository<Member>
{
public Task<IQueryable<Member>> GetAllEntities()
{
return Task<IQueryable<Member>>.Factory.StartNew(() => new Context().Members.AsQueryable());
}
}
3-BLL : for sake of simplicity : there is no Business Logic Layer
4- PL (Domain.Application MVC Project) : Member Controller :
public async Task<ActionResult> Index()
{
var members = await _repository.GetAllEntities();
return View(members);
}
Note : i depended on DbContext to create DB with name like : Domain.DataLayer.Context but it didn't craete DB so i created the DB and passed the connectionString through Context constructor like this :
namespace Domain.DataLayer
{
public class Context : DbContext
{
public Context(): base("InterviewDemo") // i tried also base("name=InterviewDemo")
{
}
public DbSet<Member> Members { get; set; }
public DbSet<Task> Tasks { get; set; }
public DbSet<Commint> TaskHistory { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Configurations.Add(new MemberConfig());
modelBuilder.Configurations.Add(new TaskConfig());
modelBuilder.Configurations.Add(new CommintConfig());
base.OnModelCreating(modelBuilder);
}
}
}
I am having an issue with using Fluent NHibernate automapping with Inheritance. Below is my entity setup (abbreviated for simplicity). I have configured Fluent NHibernate to create 1 class for the hierarchy with a discriminator column. The automapping appears to be working correctly as when I generate a database, one table is created named "AddressBase" with a discriminator column that signals what type of address each row is.
The problem lies in the face that when I call the method "GetPrimaryBillingAddress()" on the UserAccount class, instead of just querying Billing Addresses, NHibernate is creating a query that looks at both Billing and Shipping Addresses. It doesn't take into account the discriminator at all. I am assuming there is some sort of configuration I can set but have not been able to find anything.
public abstract class AddressBase : ActiveRecord<AddressBase>
{
public virtual long Id { get; set; }
public virtual string Address1 { get; set; }
}
public class AddressBilling : AddressBase
{
public class TypedQuery : ActiveRecordQuery<AddressBilling> { }
public virtual bool IsPrimary { get; set; }
}
public class AddressShipping : AddressBase
{
public class TypedQuery : ActiveRecordQuery<AddressShipping> { }
[Display(Name = "Is Primary")]
public virtual bool IsPrimary { get; set; }
}
public class UserAccount : ActiveRecord<UserAccount>
{
public virtual long Id { get; set; }
public virtual IList<AddressBilling> BillingAddresses { get; set; }
public virtual IList<AddressShipping> ShippingAddresses { get; set; }
public UserAccount()
{
BillingAddresses = new List<AddressBilling>();
ShippingAddresses = new List<AddressShipping>();
}
public virtual AddressBilling GetPrimaryBillingAddress()
{
if (BillingAddresses.Any(x => x.IsPrimary))
{
return BillingAddresses.Single(x => x.IsPrimary);
}
return BillingAddresses.FirstOrDefault();
}
public virtual AddressShipping GetPrimaryShippingAddress()
{
if (ShippingAddresses.Any(x => x.IsPrimary)) {
return ShippingAddresses.Single(x => x.IsPrimary);
}
return ShippingAddresses.FirstOrDefault();
}
}
UPDATE:
Here is the Mapping override functions used in the automapping:
private static FluentConfiguration GetFluentConfiguration(string connectionStringName = "CS")
{
var autoMapping = AutoMap
.AssemblyOf<Product>(new Mapping.AutoMappingConfiguration())
.Conventions.Setup(c =>
{
c.Add<Mapping.ForeignKeyConvention>();
c.Add<Mapping.DiscriminatorConvention>();
})
.IgnoreBase<AddressBilling.TypedQuery>()
.IgnoreBase<AddressShipping.TypedQuery>()
.IncludeBase<AddressBase>();
return Fluently.Configure()
.Database(MsSqlConfiguration.MsSql2005.ConnectionString(c => c.FromConnectionStringWithKey(connectionStringName)))
.Mappings(m => m.AutoMappings.Add(autoMapping));
}
public class AutoMappingConfiguration : DefaultAutomappingConfiguration
{
public override bool ShouldMap(Type type)
{
var isStatic = type.IsAbstract && type.IsSealed;
return type.Namespace == typeof(Entities.Product).Namespace && !isStatic;
}
public override bool IsDiscriminated(Type type)
{
if (type == (typeof(Entities.AddressBase))) {
return true;
}
return false;
}
public override string GetDiscriminatorColumn(Type type)
{
return "Type";
}
public class DiscriminatorConvention : ISubclassConvention
{
public void Apply(ISubclassInstance instance)
{
//Address
if (instance.Name == typeof(AddressBilling).AssemblyQualifiedName)
{
instance.DiscriminatorValue(Enums.AddressType.BillingAddress);
}
else if (instance.Name == typeof(AddressShipping).AssemblyQualifiedName)
{
instance.DiscriminatorValue(Enums.AddressType.ShippingAddress);
}
}
}
Thanks!
Please, try to change your class UserAccount like this:
public class UserAccount : ActiveRecord<UserAccount>
{
public virtual IList<AddressBase> Addresses { get; set; }
public virtual IList<AddressBilling> BillingAddresses { get {return this.Addresses.OfType<AddressBilling>();} }
public virtual IList<AddressShipping> ShippingAddresses { get {return this.Addresses.OfType<AddressShipping>();} }
// ...
}
Of course, only Addresses property should be mapped here.
I've been trying for ages to find an example (because I can't get it to work myself) of the correct mapping for a one-to-many relationship on an abstract class of a table-per-subclass implementation, in fluent nHibernate.
An example below: I'm looking to map the list of Fines on the Debt abstract base class to the Fine class.
If anyone knows of any tutorial or example they've come across before please let me know.
public abstract class Entity
{
public int Id { get; set; }
}
public abstract class Debt : Entity
{
public decimal Balance { get; set; }
public IList<Fine> Fines { get; set; }
public Debt()
{
Fines = new List<Fine>();
}
}
public class CarLoan : Debt
{
}
public class CreditCard : Debt
{
}
public class LoanApplication : Entity
{
public IList<Debt> ExistingDebts { get; set; }
public LoanApplication()
{
ExistingDebts = new List<Debt>();
}
}
public class Fine
{
public Int64 Cash { get; set; }
}
Can you tell us where exactly you're having difficulty? What have you tried?
Obviously, you'll need to declare all of your members as virtual (I assume this was an oversight in the example).
Basically, though, it would look like this:
public DebtMap : ClassMap<Debt>
{
public DebtMap()
{
Id(x => x.Id);
HasMany(x => x.Fines);
}
}
public FineMap : ClassMap<Fine>
{
public FineMap()
{
Id(x => x.Id);
// map other members
}
}
public CarLoanMap : SubclassMap<CarLoan> { }
public CreditCardMap : SubclassMap<CreditCard> { }
I am pretty new to S#harp architecture and fluent nhibernate. I was trying to build a sample solution using the template.
MappingIntegrationTest fails for me when I try to run it for the following domains
public class Component
{
public virtual string comp { get; set; }
}
public class Parent : Entity
{
public virtual string Type { get; set; }
}
public class Child1: Parent
{
public virtual Component Blah { get; set }
}
The ParentMap looks like following:
public class ParentMap : IAutoMappingOverride<Parent>
{
public void Override(AutoMapping<Parent> mapping)
{
mapping.DiscriminateSubClassesOnColumn("Type")
.SubClass<Child1>(m =>
{
m.Component(c => c.Blah, c =>
{
c.Map(x => x.comp , "comp");
}
}
}
}
The mapping integration tests fail for me
* Database was not configured through Database method.
----> NHibernate.MappingException : An association from the table Parent refers to an unmapped class: Component
Do I need to remove these classes from AutoMapper?
