Hi,

when joining on identityuser in our modules services, we get an "Cannot use multiple context instances within a single query execution" exception. Our DbContextBase has the ReplaceDbContext attribute and implements all dbcontext interfaces of these dbcontext

  • ABP Framework version: v5.3.0
  • UI type: Blazor
  • DB provider: EF Core
  • Tiered (MVC) or Identity Server Separated (Angular): no
  • Exception message and stack trace:
System.InvalidOperationException: Cannot use multiple context instances within a single query execution. Ensure the query uses a single context instance.

    hi

    Please try to use code

    context.Services.AddAbpDbContext<YourDbContext>(options =>
{
    options.ReplaceDbContext<IIdentityDbContext>();
});

    nope - doesnt work. Always the same exception tried:

    • ReplaceDbContext inside AddAbpDbContext ( only IIdentityDbContext ) and attribute on context
    • ReplaceDbContext inside AddAbpDbContext ( only IIdentityDbContext ) without attribute on context
    • ReplaceDbContext inside AddAbpDbContext ( all replaced context ) and attribute on context
    • ReplaceDbContext inside AddAbpDbContext ( all replaced context ) without attribute on context
    • ( also tried to put options.AddDefaultRepositories( includeAllEntities: true ) in PreConfigureServices )

    So you say you tried and it works for you ?

    updated to 6.0.0 -> same result

    here is an example project, tried to be as close as possible to our project / structure. ( removed test projects, removed apb commercial from nuget config )

    hi

    var query = from example in await Repository.GetQueryableAsync()
	join user in await _userRepository.GetQueryableAsync() on example.UserId equals user.Id
	select new
	{
		example,
		user.Name
	};

    The Repository is MultiTenantDbReplace.Example.EntityFrameworkCore.ExampleDbContext The _userRepository is MultiTenantDbReplace.EntityFrameworkCore.MultiTenantDbReplaceTenantDbContext

    im not sure what you mean.

    So how do i get both entities in the same context ? I thought that is the purpose of ReplaceDbContext ( tried to add IMultiTenant to exampleEntity, but same result )

    Found one problem: options.AddDefaultRepository<TEntity> prevents ReplaceDbContext to work But ExampleEntity still in host context and user in tenant context

    Found the last problem: you need a custom repository, it looks like MultiTenant doesnt work with default genrated repository

    With custom repository and multi-tenant, all entities are on the same context, finally.

    i belive there are two bugs that should be fixed:

    1. AddDefaultRepository on an entity which is part of an context with ReplaceDbContext prevents this entity from being part of the target context
    2. injected default repositories like IReadOnlyRepository in application services for entities with IMultiTenant get the host context instead of the tenant context when they do not have a custom repository
