Check User Roles

Checking user role is a common requirement in MS CRM application. Here is the code using oData query.

//Get user roles

CustomcheckSecurityRole: function () {

    //Getting the user id of the logged in user 

    var user = Xrm.Page.context.getUserId();

    var loggedInUserId = user.substring(1, 37);

    flag = false;

    //Getting the roles of logged in user

    var odataSelect = "/SystemUserSet?$select=systemuserroles_association/Name,systemuserroles_association/RoleId&$expand=systemuserroles_association&$filter=SystemUserId eq guid'" + loggedInUserId + "'";

    var requestResults = GetEntityData(odataSelect);

    var roleName = ""; 

    //Comparing the roles of logged in user,If Display Role or Read All User is present return false

    for (var i = 0; i < requestResults.results[0].systemuserroles_association.results.length; i++) {

        roleName = requestResults.results[0].systemuserroles_association.results[i].Name; 

        if (roleName.toString() != "System Administrator")

        {

            flag = true;

        } 

    }

    return (flag);

}

//Get entity data. It requires oData query.

GetEntityData :function(OData) {

    var serverURL = getServerUrl();

    var oDataEndpointUrl = serverURL + "/XRMServices/2011/OrganizationData.svc";

    oDataEndpointUrl += OData;

    var service = GetRequestObject(); 

    if (service != null) {

        service.open("GET", oDataEndpointUrl, false);

        service.setRequestHeader("X-Requested-Width", "XMLHttpRequest");

        service.setRequestHeader("Accept", "application/json, text/javascript, */*");

        service.send(null);

        var requestResults = eval('(' + service.responseText + ')').d;

        if (requestResults != null)

            return requestResults;

        else

            return null;

    }

}

GetRequestObject: function () {

        if (window.XMLHttpRequest) {

            return new window.XMLHttpRequest;

        }

        else {

            try {

                return new ActiveXObject("MSXML2.XMLHTTP.3.0");

            }

            catch (ex) {

                return null;

            }

        }

    } 

getServerUrl: function {

       var customServerURL = document.location.protocol + "//" + document.location.host + "/" + Xrm.Page.context.getOrgUniqueName();

       return customServerURL;

      }
