The Object Manager opens displaying the Property_c object. On the Property_c element, click the gear icon and then select View Object.There is a lookup relationship from the Broker_c custom field on the Property_c custom object to the Broker_c custom object. Hover over the relationship line that connects Property_c to Broker_c.(The API name for a custom field is the custom field name with _c added at the end.) The Property_c custom object has two custom fields: Picture_c and Broker_c. These are the custom objects we use in this unit. In the Select from list, choose Custom Objects.(The API name for a custom object is the custom object name with _c added at the end.) Display Element Names shows us field API names instead of field labels. Remember that in code we use field API names. If you see Broker rather than Broker_c, click View Options and then select Display Element Names.In your Trailhead Playground, click and select Setup.We use objects in the DreamHouse app, so first let’s examine the DreamHouse schema (data model) to understand how the data is structured. Now we discuss how to query custom objects. Until now, we’ve queried only standard objects. Click the Properties tab, and familiarize yourself with the sample data.In the confirmation dialog box, click OK.(If you don’t see the Data Import tab, expand the More list.) Click, type Dream in the Search box, and then select the DreamHouse app.When the package is finished installing, you see a confirmation page and get an email to the address associated with your playground. If prompted to approve third-party access, select Yes, grant access… and then click Continue.Select Install for Admins Only, then click Install.If you don’t see the Playground Starter app, copy this link to the Dreamhouse Package and check out Install a Package or App to Complete a Trailhead Challenge on Trailhead Help. If not, from the App Launcher ( ), find and open Playground Starter and follow the steps. If you see a tab in your org labeled Install a Package, great! Skip ahead to step 1. If it’s not already open, launch your Trailhead Playground. Let’s install the app in your Trailhead Playground and import sample data. The examples and hands-on activities in the rest of this module use a sample real estate application called DreamHouse.
