hi, i want to get all parent permissions with childs to create permission tree by jstree.

this is my code in permissionAppService:

public virtual List<PermissionListDto> GetAllPermissionList()
{
 var permissions = _permissionManager.GetAllPermissions(true).Where(a=>a.Parent==null).ToList();
            return permissions.MapTo<List<PermissionListDto>>();
}

and my PermissionListDto:

[AutoMapFrom(typeof(Permission))]
    public class PermissionListDto 
    {
        public virtual ICollection<PermissionListDto> Children { get; }
        public virtual string Description { get; set; }
       public virtual string DisplayName { get; set; }
        public virtual string Name { get; set; }

        public virtual string Text { get; set; }

        public virtual PermissionListDto Parent { get; set; }
    }

but when i call my function in javacsript, i get this error in browser console:

There is an action GetAllPermissionList defined for api controller app/permission but with a different HTTP Verb. Request verb is GET. It should be Post

i think that, automap from IReadonlylist to ICollection (for childrens) is the problem, but i dont khnow how to solve it. please help me, :cry:

    Hi,

    According to error message your making a GET reuqest. You should make a POST request.

    How do you call this GetAllPermissionList from client side ?

    hi and thank you for reply. i solve this error.

    but i have another problem. in PermissionAppService i want to load only parent permissions with childrens of this parents.

    and i write this code:

    var permissions = _permissionManager.GetAllPermissions(true).Where(a=>a.Parent==null).ToList();

    when i write this where condition, only parent permissions returned, but childrens of parent permissions are null and does not load. and when i remove where condition,all parents and childerens are load together and my program display incorrect tree. how can i solve this problem?

    Hi,

    You can get all permissions and parent permissions like this.

    var permissions = PermissionManager.GetAllPermissions();
var rootPermissions = permissions.Where(p => p.Parent == null);

    Then you can fill child permissions using a recursive method like this.

    foreach (var rootPermission in rootPermissions)
{
    AddChildPermission(rootPermission, permissions);
}

    void AddChildPermission(...)
{
.....
}

    Hi,

    In AddChildPermission when you say fill children do you mean rootPermission.CreateChildPermission or something else? Am sorry having a hard time trying to populate the children. This is what i have so far:

    public List<PermissionListDto> GetPermissions()
        {
            var permissions = PermissionManager.GetAllPermissions();
            var rootPermissions = permissions.Where(p => p.Parent == null);

            foreach (var rootPermission in rootPermissions)
            {
                AddChildPermission(rootPermission, permissions);
            }

            List<PermissionListDto> retValue = rootPermissions.MapTo<List<PermissionListDto>>();

            return retValue;
        }

        private void AddChildPermission(Permission rootPermission, IReadOnlyList<Permission> permissions)
        {
            foreach(var child in rootPermission.Children)
            {
//dont know what to do in here
            }
        }
