In this section, you will create the following:
A template defines the default content of a new page. Complex websites may use several templates for creating the different types of pages in the site. Further, the set of templates may become a blueprint used to rollout changes to a cluster of servers.
In this exercise, all pages are based on one simple template.
In the explorer pane of CRXDE Lite
In the Create Template dialog, type the following values and then click Next:
An SCF Sandbox Play Template
An SCF Sandbox template for play pages
The Label is used for the node name.
The Resource Type appears on the
playpage’s jcr:content node as the property
sling:resourceType. It identifies the component (resource) that renders the content when requested by a browser.
In this case, all pages created using the
playpagetemplate are rendered by the
an-scf-sandbox/components/playpage component. By convention, the path to the component is relative, allowing Sling to search for the resource first in the
/apps folder and, if not found, in the
If using copy/paste, ensure the Resource Type value has no leading or trailing spaces.
“Allowed Paths” refers to the paths of pages which use this template, such that the template is listed for the New Page dialog.
To add a path, click the plus button
+ and type
/content(/.*?lang=en)? in the text box that appears. If using copy/paste, ensure there are no leading or trailing spaces.
Note: The value of the allowed path property is a regular expression. Content pages that have a path that matches the expression can use the template. In this case, the regular expression matches the path of the /content folder and all its subpages.
When an author creates a page below
playpagetemplate titled “An SCF Sandbox Page Template” appears in a list of available templates to use.
After the root page is created from the template, access to the template could be restricted to this website by modifying the property to include the root path in the regular expression, i.e…
Click Next in the Allowed Parents panel.
Click Next in the Allowed Children panels.
Once you click OK and finish creating the template, you will notice red triangles showing in the corners of the Properties tab values for the new
playpagetemplate. These red triangles indicate edits which have not been saved.
Click Save All to save the new template to the repository.
Create the component that defines the content and renders any pages created based on the playpage template.
In CRXDE Lite, right-click
/apps/an-scf-sandbox/components and click Create > Component.
By setting the node’s name (Label) to playpage, the path to the component is
which corresponds to the Resource Type of the playpage template (optionally minus the initial
/apps/ part of the path).
In the Create Component dialog, type the following property values:
Click Next until the Allowed Children panel of the dialog appears
Verify that the path to the component and the resourceType for the template match.
The correspondence between the path to the playpage component and the sling:resourceType property of the playpage template is crucial to the correct functioning of the website.
