I am writing this article to show you how to create and assign user role. Create a new asp.net web application project with MVC template along with individual authentication. You have noticed that AspNetRoles, AspNetUsers etc tables are already available in our project . So, we can make use of these tables to fulfill our need . Find and open the Startup.cs file from the solution explorer .You can add here function to create roles.
In this function we are making our database object with name context and role manager object . Then we are checking whether visitor role already exist in our roles table if this role exist then we do not create this role and vice versa. For creating a role we first create role object then give role name to this and then we create that role . Like this
After that you need to call this function in configuration method to make it work.
Built your project and run . Your roles are being added . You can verify it by opening your AspNetRoles table .
Now this will show how you can assign these roles to user .
You need to add new column in users table with name UserRole .For this go to Model->Identity.cs open it and add user role property .
After this you need to perform migrations because you are updating a users table by adding a new column with the name UserRole . For this search and open package manager console in visual studio and pass these three commands.
Now, add a UserRole property in RegisterViewModel. For this go to Model->AccountViewModel open it and find RegisterViewModel and add UserRole property in it .
Go to Views->Account->Register.cshtml open it and add the following for display.
After that go to the Controller->AccountController .
Find the Register method and then add the UserRole and make it mapping to other tables like AspNetUserRoles table as well.
Now build the project and run it . You should now understand how to create and assign roles to users.
