access lookup item description column

By using 'this.get("xxx").value' and 'this.get("xxx").displayValue' in the page edit code, it is possible to get the id and Name of a lookup item. Is there a way to access the value of the Description column too ?



The only way to get the description is to first get the lookup item Id, then use an EntitySchemaQuery to get the description from the lookup object.

Something like this:

// get account type. then use an esq to get the 
// description for the selected type
var accountType = this.get("Type");
var esq = Ext.create("Terrasoft.EntitySchemaQuery", {
    rootSchemaName: "AccountType"
esq.getEntity(accountType.value, function (result) {
    if (result.success) {
        var desc = result.entity.values.Description;
        console.log("Description is: " + desc);
}, this);

I have an article on the basics of using EntitySchemaQuery, if needed, here:


It's possible to add the "Description" column of a lookup object by setting columns property of "lookupListConfig". There is an example for "Type" lookup below:

     attributes: {
            "Type": {
                lookupListConfig: {
                    columns: ["Description"]

After that you can get "Description" column value by using  this.get("Type").Description
