Creating a Child Object in Application Composer



Steps:

  1. Hello, my name is John, and today we are discussing extending  applications using Application Composer.

    Step 1

  2. In this demo, I will show you how to create a child object in Application Composer.

    Step 2

  3. This is the first in a series of related demos that show how to create a child object, add fields to it, and display it in the UI of a parent object.

    You can create child objects to add functionality to both custom objects and to existing application objects.

    Step 3

  4. Here is the child object we are building in this set of demos.

    It's called Activity and you use it to record tasks that are carried out to resolve a trouble ticket.

    All child objects appear as subtabs in the edit pages of the parent object, in this case the custom object Trouble Ticket.

    Child objects do not have a separate work area, and their records are saved  only when you save the parent object records.

    Step 4

  5. To create a child object, you begin by navigating to the parent object in Application Composer and clicking the Create Child Object button.

    Step 5

  6. Click the Create Child Object button.

    Step 6

  7. In the Display Label field,  we'll enter the name of the child object that will appear in the user interface. In our case, that's Activity.

     

    Enter the desired information into the Display Label field. Enter

     a valid value
     e.g.
     "Activity"
    .

    Step 7

  8. We press Tab and the rest of the fields are populated for us.

     

    Press [Tab].

    Step 8

  9. We don't  have to change the Plural Label field as we did when we created the parent object. That's because this field is not used in child objects.

    Step 9

  10. The Record Name Label field is the name of the field where  users enter the activity title. We're OK with Activity Name here.

     

    Step 10

  11. The Child Collection Name is the internal name for this set of child object records. You can use it for writing Groovy scripts.

    Step 11

  12. We don't need to make any changes here, so we are done.

    Step 12

  13. Click the OK button.

    Step 13

  14. The application displays an overview of the child object we just created. In the next demo, we'll add some fields.

    Step 14

  15. In this demo you learned how to create a child object in Application Composer.
