When working with Dynamics CRM forms, we can use the XRM client
object model to query the fields and controls on the page. A common field on
every form is the current user id. This however only provides the internal
system id or GUID. When we need more information about the user, we can use the
ODATA web services to get additional information.
This script provides us with a helper function to enable us
to find additional information about the current logged on user.
if (typeof (OGBIT) == "undefined") { OGBIT = {}; }
OGBIT.UserInfo
= {
Get: function () {
var userInfo = {};
if (self.userName == '') {
var serverUrl = window.location.protocol + "//" +
window.location.host + "/" + Xrm.Page.context.getOrgUniqueName();
var userId = Xrm.Page.context.getUserId();
var req = serverUrl + "/xrmservices/2011/OrganizationData.svc/SystemUserSet(guid'{0}')?$select=EmployeeId,FullName,InternalEMailAddress,SystemUserId,DomainName".replace('{0}', userId);
try {
$.ajax({
type: "GET",
contentType: "application/json;
charset=utf-8", datatype:"json",async:false,
url: req,
beforeSend: function (XMLHttpRequest) {
XMLHttpRequest.setRequestHeader("Accept", "application/json");
},
success: function (data, textStatus,
XmlHttpRequest) {
userInfo = data.d;
userInfo.status = true; //dynamic property
},
error: function (XmlHttpRequest,
textStatus, errorObject) {
userInfo.status = false;
//add error handling
}
});
} catch (e) { }
}
return userInfo;
}
}
The script first calls the getUserId method of the page
context. This returns the system id which we can then use to make an ODATA
request to get the additional user information. The ODATA query to get the user
information has this format:
SystemUserSet(guid'{0}')?$select=EmployeeId,FullName,InternalEMailAddress,SystemUserId,DomainName
The SystemUserSet allows us to query the System User entity.
We query for the current user with the
guid’{0}’ parameter. The $select query option is used to indicate what additional
fields should be returned. Those fields are listed below:
Parameters:
|
Field Name
|
Description
|
|
EmployeeId
|
employee id
|
|
FullName
|
First and last name
|
|
InternalEMailAddress
|
Email
|
|
SystemUserId
|
Internal ID or GUID
|
|
DomainName
|
Username with this format:
DomainName\Username
|
The following snippet can be used to test the script. With
this function, we just call the Get method and assign the returning information
into local variables.
function GetUserInfo() {
if (typeof (OGBIT.UserInfo) != 'undefined') {
var info = OGBIT.UserInfo.Get();
if (info.status) {
var empId = info.EmployeeId;
var name = info.FullName;
var email = info.InternalEMailAddress;
var userName = info.DomainName;
var id = info.SystemUserId;
} else {
alert('Unable to find user');
}
}
}
I hope this Script helps you get more understanding on how
to interact with MS CRM.
