Use a variable with IsGranted(AppPermissions. #5082

strategy9 created 6 years ago

In a View I have a foreach loop. I have the string name of a set of AppPermissions in a table. I want to iterate through the data (to fill a select list) by evaluating permissions.

How can I use a variable in the IsGranted statement like:

if (IsGranted(AppPermissions.variablename))...

I've tried a bunch of different options using razor formatting but haven't figured it out yet. Is it possible?

Hi,

I think isn't possible for dynamical items. If you have static items list then you can use hard codes in your razor

<select class="form-control" name="IsApprovedFilter" id="IsApprovedFilterId">
                           @if (IsGranted(Pages_Blogs_Comments))
                            {
                                      <option value="-1">@L("All")</option>
                                      <option value="1">@L("True")</option>
                            }
                                <option value="0">@L("False")</option>
                            </select>

OR You can add new string array property to your entity

string[] RequiredPermissions {get; set;}

Usage:

@if (IsGranted(AppPermissions.Pages_SomePermission))
 {
    @foreach (var object in Model.YourObject.Where(e =>  e.RequiredPermissions.Contains("yourSomePermission")))
    {
        @Html.Partial("_ObjectPartialView", object)
    }
}
    @foreach (var object in Model.YourObject.Where(e =>  e.RequiredPermissions.Contains("yourOtherRequiredPermission")))
    {
        @Html.Partial("_ObjectPartialView", object)
    }

hi,

you can filter the data in your controller/application service then give it to your view. and as @CsBeginner says you can use

@IsGranted("myPermission")
