Injecting permissions dynamically #3933 | Support Center

sago created 7 years ago

i use module zero, and i injected some permissions dynamically and it stored as granted after saving . but GetGrantedPermissionsAsync function doesn't return them it returns only the permissions that only matches the hard coded ones and i tried to append them manually but apppermissions table is inaccessible. i need to append them to be shown as checked permissions

Can you show relevant code?

sago created 7 years ago

grantedPermissions = (await _roleManager.GetGrantedPermissionsAsync(role)).ToArray(); //because this function doesn't return my injected objects i iterated permissions on role.permessions as shown in below but the data only exist at the first time if i open them again it becomes null

            if (role.Permissions!=null)
            {
               
                foreach (var item in role.Permissions)
                {
                    Permission p = new Permission(name: item.Name, displayName: L(item.Name));
                    grantedPermissionsList.Add(p);
                }
                if (grantedPermissionsList.Any())
                {
                    grantedPermissions = grantedPermissionsList.ToArray();
                }
                
            }

That should work. Can you show the complete method instead of your workaround?

public async Task<GetRoleForEditOutput> GetRoleForEdit(NullableIdDto input) { var permissions = PermissionManager.GetAllPermissions();

        var grantedPermissions = new Permission[0];
        var grantedPermissionsList = new List&lt;Permission&gt;();
        RoleEditDto roleEditDto;

        if (input.Id.HasValue) //Editing existing role?
        {
            var role = await _roleManager.GetRoleByIdAsync(input.Id.Value);
            grantedPermissions = (await _roleManager.GetGrantedPermissionsAsync(role)).ToArray();

Do you mean that the permissions are already in the database and that every time you get (without editing), it doesn't give the same result?

Yes , role.permission :some times comes with null and sometimes comes with my permissions that have been granted from my injected objects ,and it 's never comes from GetGrantedPermissionsAsync() function

So the roles do not actually have permissions, but only from your injected objects?

sago created 7 years ago

no it has granted some permission of both (hard coded ones and injected ones), but GetGrantedPermissionsAsync() function returns only the granted permissions that matches hard coded ones

but i noticed that GetRoleByIdAsync() has a property called permission this property some times comes with my granted injected permissions and sometimes comes with null (mostly comes with null).

The permissions in the role from GetRoleByIdAsync are populated only if the permissions exist in the current context. You should not rely on the permissions here.

Always use GetGrantedPermissionsAsync, which returns permissions in the database, then inject other permissions.

i think the problem because of the caching how can i disable cache of this page

aaron created 7 years ago

Support Team

Use AsNoTracking. Instead of GetRoleByIdAsync, do:

var role = await Repository.GetAll().AsNoTracking().FirstAsync(x => x.Id == input.Id.Value);

i think the problem is with caching because after i clear cache from maintenance page it works fine,how can i disable page to be cached

The problem is not with page caching. Why does it matter if you need to GetGrantedPermissionsAsync and inject anyway?

thanks aaron very much the problem is solved by your effort

var role = await _role.GetAllIncluding(a=>a.Permissions).AsNoTracking().FirstAsync(x => x.Id == input.Id.Value);
