Activities of "defacto"

Hi, I want to be sure about something.

We want to host our Web Api on 2 servers. Apart from the Framework, we do not have any server-based processes such as session, local server cache, which we specially develop. We use a single database.

Should api requests made by clients go to the web api server where the client is logged in? Does hosting the Web Api on multiple servers create problems in Authorization or other situations?

Thanks

Here is github issue.

DevelopmentObjectiveCategoryMapping ia a many-to-many table. When we insert 3 entities into it we only see that only the latest one is inserted. Do you have any idea why this could be happening?

public async Task CreateObjective(CreateDevelopmentObjectiveInput input)
{
     var o1 = new DevelopmentObjective
     {
         FormId = input.FormId,
         TemplateId = input.TemplateId,
         MeasureOfSuccess = input.MeasureOfSuccess,
         CompletionDate = input.CompletionDate,
         Status = input.Status
     };
    
     await _objectiveRepository.InsertAndGetIdAsync(o1);

     var docm1 = new DevelopmentObjectiveCategoryMapping
     {
         ObjectiveId = o1.Id,
         CategoryId = input.ObjectiveCategory.CategoryId,
         OtherCategoryName = input.ObjectiveCategory.OtherCategoryName,
         CategoryDescription = input.ObjectiveCategory.CategoryDescription
     };

     var docm2 = new DevelopmentObjectiveCategoryMapping
     {
         ObjectiveId = o1.Id,
         CategoryId = input.ObjectiveCategory.CategoryId,
         OtherCategoryName = input.ObjectiveCategory.OtherCategoryName,
         CategoryDescription = input.ObjectiveCategory.CategoryDescription
     };

     var docm3 = new DevelopmentObjectiveCategoryMapping
     {
         ObjectiveId = o1.Id,
         CategoryId = input.ObjectiveCategory.CategoryId,
         OtherCategoryName = input.ObjectiveCategory.OtherCategoryName,
         CategoryDescription = input.ObjectiveCategory.CategoryDescription
     };

     await _objectiveCategoryMappingRepository.InsertAndGetIdAsync(docm1);
     await _objectiveCategoryMappingRepository.InsertAndGetIdAsync(docm2);
     await _objectiveCategoryMappingRepository.InsertAndGetIdAsync(docm3);
}

We want to create a new user with the help of a backround task by using Hangfire integraion of ABP for 16.000 Employees which is coming from our SAP service. Below is the code which demonstrates for a single creating action. We even couldn't create a single user. There is our code and exception. Please help us.

I'm trying to simply update navigation properties of an entity but i couldn't succeed. I did a some seaching on the internet but those solution didn't work for me. i actually solved this easy-looking problem but the way i solved it did not satisfy me.

Here is an appropriate forum post and answer by @ismcagdas. Here is an appropriate sof question.

At this and this lines we send a mail to users to inform them about their accounts. But this mail doesn't contain password if we check "Set random password" checkbox checked. This is a desired behaviour? If so, how a user would log in the system.

This fixes the issue.

if (input.SetRandomPassword)
{
    var randomPassword = User.CreateRandomPassword();
    user.Password = _passwordHasher.HashPassword(user, randomPassword);
    input.User.Password = randomPassword;
}
