Displaying Object Entries
Available 7.4+
With Liferay Objects, you can use existing DXP frameworks to display Object entries dynamically in Sites. This includes collection displays for multiple entries and display pages for individual entries.
When an Object is published, Liferay creates a Collection Provider for use with the Collection Display fragment to display multiple Object entries. You can also configure the fragment to style, filter, and paginate the collection. And since published Objects are integrated with the Info framework, you can select them as the content type for Display Page Templates. When selected, the Object is set as the template’s mapping source, so you can easily map fragment fields to Object fields to create flexible page displays for individual Object entries.
Additionally, you can use FreeMarker to create Information Templates for Objects. Once created, you can map fragment fields to your template to determine how entries are rendered in Content Pages and Display Pages.
Information Templates can be used in Content Display fragments and any other fragment with sub-elements (e.g., text, rich text) that can be mapped to Objects.
Together, these integrations enable users to leverage Liferay’s WYSIWYG page building capabilities while delivering personalized user experiences.
Using the Collection Provider for Objects
Once you’ve published an Object, follow these steps to use the Collection Display fragment to display an Object’s entries:
Create a new Content Page or Display Page Template. Alternatively, begin editing (
) an existing one.noteYou can also create a Collection Page using the Collection Provider. See Collections and Collection Pages for more information.
Drag and drop the Collection Display fragment into the Page or Template from the Fragments and Widgets (
) sidebar.
Select the Collection Display Fragment to access its configuration options and click Select Collection in the General tab.
In the modal window, click the Collection Providers tab and select the Object’s provider.
(Optional) Filter which Object entries are displayed. You can filter by any Picklist or Boolean fields in the Object.
To do this, click the Collection Options button (
) and select Filter Collection.
Then, select the desired filters and click Apply.
After selecting the desired provider, use additional fragment options to determine how Object entries are displayed, including List Style and Pagination.
Creating Display Page Templates for Objects
When created, each Object entry is assigned automatically a dedicated friendly URL that uses the following pattern: server-address/l/objectEntryId (e.g., https://mysite.com/l/44337). To view an entry at its URL, you must first create a Display Page Template for the Object.
Follow these steps:
Open the Site Menu (
), expand Design, and go to Page Templates.Click the Display Page Templates tab.
Click the Add button (
) and select the Blank template.This opens a modal window.
Enter a name and select the desired Object for Content Type.
Click Save.
This creates a blank template with the selected Object as its default mapping source and redirects you to the template editing page.
Use page fragments and widgets to create flexible, dynamic displays for Object entries. See Using Display Page Templates for information.
Add the Page Comments widget so end users can comment on entry display pages.
noteYou must enable comments for the object definition. Otherwise, the widget is hidden in the display page.
When finished, click Publish.
Click the Actions button (
) for your template and select Mark as Default.This template is now used to render the Object’s entries whenever users visit their friendly URLs.
Enabling Comments
Open the Global Menu (
), go to the Control Panel tab, and click Objects.Edit an object definition.
In the Details tab, enable comments and click Save.
Creating Information Templates for Objects
Open the Site Menu (
) and go to Design → Templates → Information Templates.Click Add (
)Enter a name and select the desired Object.
Click Save. This redirects you to the template design page.
(Optional) Click Actions (
) in the Application Bar, select Import Script, and choose an .ftlfile to import. This replaces the current template with the file’s FreeMarker script.
Use FreeMarker to design your template.
In the Elements side panel (
), you can access available fields from the selected Object’s structure.
(Optional) Add a description or image to the template in the Properties side panel (
).
Click Save when finished.
You can now select from the template when mapping Object entries to fragment fields.
Adding Entries to Navigation Menus
Since Objects are integrated with the info framework, you can add Object entries to navigation menus to provide quick access. All published Objects automatically appear as available sources for menu elements. See Using the Navigation Menus Application for more information.
