I am having trouble to create an expand query using the REST API.

I have two lists which are linked.
PIR
Title, Date, Number

SIR
Title, PIR2SIR (lookup to Title in PIR), Date, Number
Now I want to display all listitems from PIR with their related SIR's 

$.ajax({

    url: url + "/_api/web/lists/getbytitle('" + listname + "')/items?$select=Title,Date, Number,Title/PIR2SIR&$expand=Title",
    method: "GET",                                                      
    headers: { "Accept": "application/json; odata=verbose" },
    timeout: 2000,
    dataType:"json",
    success: function (data) {
        complete(data); // Returns JSON collection of the results
    },
    error: function (xhr,status,error) {
        console.log(status);
    }
});

My code returns an error. How should I use the linked list in this query?

You can expand it as 

$select=Title,Date, Number,PIR2SIR/Title&$expand=PIR2SIR

This will give you the value of PIR2SIR field.

  • Still get an error with your example. I don't know where it is from. The console just writes error, that's all. – Marco Jul 24 '18 at 11:15
  • I changed the code, now the error I get is the field PIR2SIR doesn't exists. – Marco Jul 24 '18 at 12:11
  • Your select only works when I use the second list (SIR) as source. But then I get the data in the wrong way. SIR 1.1 PIR 1 SIR 1.2 PIR 1 – Marco Jul 24 '18 at 12:25
  • yes, the query will work when you are fetching the data from SIR list since the lookup field is in the SIR list. To display : "all listitems from PIR with their related SIR's" : you can still query the SIR list to get all items which will give you the "PIR2SIR" field (which is the PIR as it is a lookup) and also the corrosponding "title" of SIR. This way you already have a mapping of SIR and PIR...am I missing something ? – Vipul Kelkar Jul 25 '18 at 3:50
  • Well I think items in the PIR list which have no SIR are not displayed for one. Secondly I need some code to display them, like: for(var i =0; i < data.d.results.length; i++) { if (eh != data.d.results[i].Eenheid) { console.log(data.d.results[i].Eenheid); eh = data.d.results[i].Eenheid; } if (PIR != data.d.results[i].PIR2SIR.Title) { console.log(data.d.results[i].PIR2SIR.Title); PIR = data.d.results[i].PIR2SIR.Title; } console.log(data.d.results[i].Volgnr); console.log(data.d.results[i].Title); – Marco Jul 25 '18 at 8:33
