Configuring RSS Feeds

To manage a Liferay site’s RSS feeds, navigate to your Site’s Site Administration → Content page and click Web Content. Site administrators can use this Web Content menu option to manage their site’s web content, including web content structures and templates, which you learned in the Creating Web Content section. Site administrators can also use this option to manage their site’s RSS feeds. To add a new feed:

  1. Go to the Feeds tab.

  2. Click the Add Feed button.

  3. Enter a Name, select a Target Page, and select a Web Content Structure for the feed.

A feed’s target page serves two purposes:

  1. The site the target page belongs to determines which web content articles appear in the feed. For example, if the target page belongs to the Marketing site, only web content articles belonging to the Marketing site appear in the feed.

  2. The target page is the page where “orphaned” web content articles are displayed. Orphaned web content articles have been published in your Site but are not displayed in specific Web Content Display applications. Liferay RSS feeds can provide links to any published web content articles, both orphaned articles and articles that have been configured to be displayed in specific Web Content Display applications. For articles that have been configured to be displayed, the RSS feeds’ links point to the Liferay page of that app. For orphaned articles, the RSS feeds’ links point to the feed’s target page. When users click on such links for orphaned articles, the full content of the orphaned article is displayed on the target page.

Figure 1: To create a new RSS feed, you only need to specify a name, target page, and web content structure. Of course, you can also configure other features of the feed such as its permissions, web content constraints, and presentation settings.

To specify a target page, you must enter the target page’s friendly URL. Note that friendly URLs don’t include the host name. For example, the friendly URL of a public page called Welcome belonging to a Site called Marketing might look like this: /web/marketing/welcome. Optionally, you can specify a target portlet ID. This would be the portlet ID of a Web Content Display application on the target page in which orphaned web content should be displayed. The application must exist or else the content isn’t displayed. The URL field contains the address of your RSS feed. It appears after you’ve actually created the feed by clicking Save.

The final two sections of the Add Feed form are for customizing the web content articles that appear in your feed.

  1. Web Content Constraints selects a web content structure to filter the articles that appear in your feed. This is useful since all web content articles are created using web content structures.

  2. Presentation Settings customizes additional details about your feed and how articles are displayed in your feed. Leave the Feed Item Content set to Web Content Description if you want a description of each article to appear in your feed. Set it to Rendered Web Content: Use Default Template if you want the full content of each article to appear in the feed. Customizing the Feed Type allows you to choose which web feed language to use for your feed. You can choose Atom 1.0 (the default), RSS 1.0, or RSS 2.0. Customize the Maximum Items to Display to choose the maximum number of articles should appear in your feed at one time. Leave the Order By Column set to Modified Date to have articles arranged in order from the last time they were published or modified. You can set the Order by Column to Display Date if you want to have articles arranged in order from the time they were configured to be displayed in a specific Web Content Display application. Lastly, you can leave the Order by Type set to Ascending to have the oldest articles at the top of the feed or you can set it to Descending to have the newest articles at the top of the feed.

When you’re done configuring your RSS feed, click Save to create your feed.

Once one or more feeds have been created, they’ll appear in a list in the Feeds tab. You can edit existing feeds using the same form used for creating them. The main difference is that when you edit an existing feed, the URL field is populated. Copy this URL into a new browser tab or window to test your feed. From the Feeds popup window, you can also customize the permissions of feeds or delete feeds.

It’s possible to completely disable RSS feeds at the instance level. You can do this by setting the rss.feeds.enabled property to false in your portal-ext.properties file. By default, it’s set to true. If you keep the default, RSS enabled, you can make several other RSS property customizations. Please refer to the RSS section of your portal.properties file for details.
