Error Role Administrator does not exist in identity mvc

Hi Sonal,

Are you refering to this project

 

https://www.c-sharpcorner.com/article/clinic-management-project-using-asp-net-mvc-5

I didn't create the seed for admin and doctor roles. You can seed the roles using Dhrumit Patel solution or manualy add in the database.

please read the repository readme

https://github.com/AhmedMah/ClinicManagement 

It's seems like there is no 'Administrator' exists that you want to assign user

so first create 'Administrator' and then add user to this role

 

Please check below code

 

after create user successfully add below code

 

var role = await _roleManager.FindByNameAsync(RoleName.AdministratorRoleName); // check role from db

if((role) == null)

{

role = await _roleManager.CreateAsync(new ApplicationRole { Name = RoleName.AdministratorRoleName });

}

UserManager.AddToRole(user.Id,RoleName.AdministratorRoleName); //assign role to user
