I am newbie of ASP.NET BoilerPlate (ABP) and I am trying to understand how to create custom mappings using AutoMapper.
if I have two classes like the following where I want the property AB to be automapped as a join of A and B:
[AutoMapTo(typeof(DestClass)] // <= do I need it for this case?
public class SourceClass {
public string A { get; set; }
public string B { get; set; }
}
public class DestClass {
public string AB { get; set; }
}
I image I have to init automapper properly by using this kind of code:
Mapper.CreateMap<SourceClass, DestClass>()
.ForMember(dest => dest.AB,
opts => opts.MapFrom(src => (src.A + ", " + src.B)));
My question is: As I am in my web module and the classes are used by my AppService, where do I place the automapper init code above? Also, do I need to decorate the classes with the [AutoMap] attrib (I think, no)?
Thank you
I try to reply by myself hoping some feedback about my solution.
[DependsOn(typeof(MyProjectCoreModule), typeof(AbpAutoMapperModule))]
public class MyProjectApplicationModule : AbpModule
{
public override void Initialize()
{
IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());
// --- MY CODE
var mapperConfiguration = new MapperConfiguration(cfg => {
cfg.AddProfile(new MyProjectMapperProfile()); // <= here my custom mapping
});
var mapper = mapperConfiguration.CreateMapper();
IocManager.IocContainer.Register(
Castle.MicroKernel.Registration.Component.For<IMapper>().Instance(mapper)
);
// --- MY CODE
}
}
public class UserAppService : MyNewHouseAppServiceBase, IUserAppService {
. . .
public UserAppService(IRepository<User, long> userRepository, AutoMapper.IMapper mapper) {
. . .
}
public async Task<ListResultOutput<UserListDto>> GetUsers() {
var users = await _userRepository.GetAllListAsync();
return new ListResultOutput<UserListDto>(
// USE THE INJECTED MAPPER
_mapper.Map<List<UserListDto>>(users)
);
}
}
What do you think about this solution?
Tnx gp
This is the same issue I have with tenant data.
All my tests running on non-tenant data works, but when I call the AppService working on tenant data it always return 0.
I tried to disable filters, set the correct tenant Id without success.
This is the test
public async Task GetShowCase_Test() {
// I call the DB just to be sure the query returns the correct # of items (16)
IList<PropertyForSale> dbShowCase = null;
await UsingDbContextAsync(async context => {
dbShowCase = await context.REProperties.OfType<PropertyForSale>()
.Include(p => p.SaleAgreement)
.Where(p => p.SaleAgreement == null)
.ToListAsync();
});
var input = new GetPfsShowCaseInput {
MaxResultCount = 100,
SkipCount = 0
};
var output = await _pfsAppService.GetShowCase(input);
output.Items.Count.ShouldBeGreaterThan(0); // this fails as items are 0!
}
This is the service method that works when I run it normally
public async Task<GetPfsShowCaseOutput> GetShowCase(GetPfsShowCaseInput input) {
// this returns 0 tiems during unit test
var items = _propertiesManager.GetShowCase(input.SkipCount, input.MaxResultCount, input.Sorting);
return new GetPfsShowCaseOutput {
Items = items.MapTo<ReadOnlyCollection<PropertyForSaleDto>>()
};
}
}
And this is the Repository code:
public IQueryable<PropertyForSale> GetShowCase(int skipCount, int maxResultCount, string sorting = null) {
var query = GetAll()
.Where(p => (p.ShowOnline && (p.SaleAgreement == null)));
// sorting and paging
query = query
.OrderByDescending(p => p.ShowOnlineDate);
query = query
.Skip(skipCount)
.Take(maxResultCount);
return query;
}
Well,
//Seed initial data for default tenant
AbpSession.TenantId = 1;
UsingDbContext(context =>
{
new TenantRoleAndUserBuilder(context, AbpSession.GetTenantId()).Create();
new DefaultTenantBusinessDataCreator(context, AbpSession.GetTenantId()).Create(20); // Gp - create app business data
});
It is you original code. My code is just the last line (// Gp ...)
TenantId is correctly 1, when I extract it from DB:
PropertyForSale pfs = null;
await UsingDbContextAsync(async context => {
pfs = await context.REProperties.OfType<PropertyForSale>()
.Include(p => p.Owner)
.Include(p => p.Solicitor)
.Include(p => p.ZipCode)
.Include(p => p.City)
.Include(p => p.Attachments)
.Include(p => p.SaleAgreement)
.FirstAsync();
});
But when I execute the line
_myRepository.FirstOrDefaultAsync(p => p.Id == pfsId)
or
AbpSession.TenantId = 1;
. . .
_myRepository.FirstOrDefaultAsync(p => p.Id == pfsId)
it returns nothing.
even the code _myRepository.GetAllList() returns an empty list.
Thanks again for your reply. I went on with tests and I think it might be a bug somewhere (in your code?) as I found a workaround to solve the issue:
if I ran the same test by calling first a _userAppService.FindUser(...), everything works! See my working new testing code:
[Fact]
public async Task GetPropertyFull_Test() {
PropertyForSale entity = null;
await UsingDbContextAsync(AbpSession.TenantId, async context => {
entity = await context.REProperties.OfType<PropertyForSale>()
.FirstAsync(u => (u.TenantId == AbpSession.TenantId));
});
// only needed for a possible bug!
await _userAppService.FindUser(long.MaxValue); // only needed for a possible bug!
// test
var output = await _pfsAppService.GetPropertyFull(entity.Id);
output.ShouldNotBeNull();
output.Id.ShouldBe(entity.Id);
}
This test works! But if I comment out code lines related to user, specifically the line:
var userDto = await _userAppService.FindUser(long.MaxValue); // only needed for a possible bug!
the test fails.
The test works even if I move the 'finduser' code in the Test's constructor leaving my test method clean:
public PfsAppService_Tests() {
_pfsAppService = Resolve<IPfsAppService>();
// only needed for a possible bug!
_userAppService = Resolve<IUserAppService>();
_userAppService.FindUser(long.MaxValue);
}
[Fact]
public async Task GetPropertyFull_Test() {
PropertyForSale entity = null;
await UsingDbContextAsync(AbpSession.TenantId, async context => {
entity = await context.REProperties.OfType<PropertyForSale>()
.FirstAsync(u => (u.TenantId == AbpSession.TenantId));
});
// test
var output = await _pfsAppService.GetPropertyFull(entity.Id);
output.ShouldNotBeNull();
output.Id.ShouldBe(entity.Id);
}
What I miss?
Going further to this point, I got the exception received on my unit test.
When I run this code:
[Fact]
public async Task GetPropertyFull_Test() {
PropertyForSale entity = null;
await UsingDbContextAsync(AbpSession.TenantId, async context => {
entity = await context.REProperties.OfType<PropertyForSale>()
.FirstAsync(u => (u.TenantId == AbpSession.TenantId));
});
. . .
}
The exception I receive when fetching the entity is:
System.TypeInitializationException : The type initializer for 'Effort.DbConnectionFactory' threw an exception.
---- Effort.Exceptions.EffortException : The Effort library failed to register its provider automatically, so manual registration is required.
a) Call the Effort.Provider.EffortProviderConfiguration.RegisterProvider() method at entry point of the application
or
b) Add the following configuration to the App.config file:
<system.data>
<DbProviderFactories>
<add name="Effort.Provider"
invariant="Effort.Provider"
description="Effort.Provider"
type="Effort.Provider.EffortProviderFactory, Effort" />
</DbProviderFactories>
</system.data>
<entityFramework>
<providers>
<provider invariantName="Effort.Provider"
type="Effort.Provider.EffortProviderServices, Effort" />
</providers>
</entityFramework>
But If I add this line of code (theoretically not neede) at the beginning of the code, all works:
[Fact]
public async Task GetPropertyFull_Test() {
var dummyService = Resolve<IUserAppService>(); // why?
PropertyForSale entity = null;
await UsingDbContextAsync(AbpSession.TenantId, async context => {
...
}
Anybody can help me?
Tnx, gp
<cite>hikalkan: </cite> this maybe related to that: <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/issues/1163">https://github.com/aspnetboilerplate/as ... ssues/1163</a> After v0.10 release, please try it again.
It is still there, but I went on with my investigation and I was able to get the exception thrown when running the code:
await UsingDbContextAsync(AbpSession.TenantId, async context => {
entity = await context.REProperties.OfType<PropertyForSale>()
.FirstAsync(u => (u.TenantId == AbpSession.TenantId));
});
I receive this error:

I hope I helped you. Gp
<cite>Shyamjith: </cite> I did wrote code here but i can't invoke it using Repository
What do you mean with this sentence? Do you mean you don't see methods from a client class of your repository? If so, it is a matter of interfaces.
Your concrete repository is probably declare in this way:
public class MySpecificRepo : SampleRepositoryBase<MyEntity, int>, IMySpecificRepo {
...
}
This means, clients see your class by the interface IMySpecificRepo.
So you have to define a ISampleRepositoryBase interface declaring the new methods added to SampleRepositoryBase and declare your Concrete Interface by extending it:
public interface ISampleRepositoryBase<TEntity, TPrimaryKey> : IRepository<TEntity, TPrimaryKey> {
// here your additional common methods declarations
...
}
public interface IMySpecificRepo : ISampleRepositoryBase<MyEntity, int> {
// here your specific repository methods
...
}
public class MySpecificRepo : SampleRepositoryBase<MyEntity, int>, IMySpecificRepo {
// here the implementations
...
}
In this way all works
Gp
Hi All, I have the same problem. Anyone solved the issue?
Hi, I am trying to implement a method into a service that create a user and then assign a role to it.
The problem is that to assign the role, I need the User.Id of the created user and I have not it but any FindBy into the same transaction return null due to the fact (I think) I am into the unit of work:
public class UserAppService : MyNewHouseAppServiceBase, IUserAppService {
// ....
public async Task CreateAdmin(CreateUserInput input) {
var user = input.MapTo<User>();
(await UserManager.CreateAsync(user)).CheckErrors(LocalizationManager);
var u = await UserManager.FindByNameAsync(input.UserName); // <-- this returns null!!!
(await UserManager.AddToRoleAsync(u.Id, StaticRoleNames.Tenants.Admin)).CheckErrors(LocalizationManager);
}
}
I can I get the user.Id by staying into the unit of work? I wish to have the operation all transaction.
Tnx gp
