if you are trying to set a String property as nullable, you cannot do that. String is a reference type and always nullable,
ABP is different than the Zero project. In ABP almost everything is module. And these modules are referenced as NuGet packages. So it's very easy to upgrade. Actually making a new module for your business is good but you don't need to create modules for your sub applications. If you want to seperate a sub application via microservice then it's OK but if you'll not seperate it from the main application, just develop it in the main project.
@buaziz did you ask question or is it a way of how you do upgrade?
then you rename your logo images. logo.png => logo-reverse.png logo-reverse.png => logo.png
as I understand from your questions, you are trying to achieve a permission problem with settings. why don't you try to use Roles for this. add a permission to your admin role. or create a new TenantRole and add permissions to TenantRole. Setting system is more application related values (there's no scope for admins or users).
See the definition https://docs.abp.io/en/abp/latest/Settings#settingdefinition. There's no option for users
duplicate of #263. closing this one.
can you try to download this sample and check with the same configuration. I think it's not related with your angular code.
I'm closing this question.
You can also use PdfSharpCore library if you want to generate PDF in cross-platform. https://www.nuget.org/packages/PdfSharpCore/
First of all, the settings with the same key is being cached, so the second call will not go to database.
Also, you can inject ISettingProvider and use GetAllAsync() to retrieve all. it's better than getting 30 of them.
If you want to multiple features you can also injectIFeatureValueRepository see
https://github.com/abpframework/abp/blob/dev/modules/feature-management/src/Volo.Abp.FeatureManagement.Domain/Volo/Abp/FeatureManagement/FeatureManagementStore.cs
in ABP v3.0 settings and permission usage will be refactored and will be made more performance
can you check this https://aspnetboilerplate.com/Pages/Documents/Zero/Organization-Units#common-use-cases it's very similar
