As a workaround for missing content-repository functionality, copy a provided file into the directory for Tcl files:

    cp /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/acs-core-docs/www/files/tutorial/note-procs.tcl /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/myfirstpackage/tcl/

To make this file take effect, go to the APM and choose "Reload changed" for "MyFirstPackage".

Our package will have two visible pages. The first shows a list of all objects; the second shows a single object in view or edit mode, and can also be used to add an object. The index page will display the list, but since we might reuse the list later, we'll put it in a separate file and include it on the index page.

Figure 9.5. Page Map

Each user-visible page in your package has, typically, three parts. The tcl file holds the procedural logic for the page, including Tcl and database-independent SQL code, and does things like check permissions, invoke the database queries, and modify variables, and the adp page holds html. The -postgres.xql and -oracle.xql files contains database-specific SQL. The default page in any directory is index, so we'll build that first, starting with the Tcl file:

[$OPENACS_SERVICE_NAME postgresql]$ cd /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/myfirstpackages/www
[$OPENACS_SERVICE_NAME www]$ emacs index.tcl

Paste this into the file.

ad_page_contract {
    This is the main page for the package.  It displays all of the Notes and provides links to edit them and to create new Notes.

Now index.adp:

  <property name="doc(title)">@page_title;literal@</property>
  <property name="context">@context;literal@</property>
<include src="/packages/myfirstpackage/lib/note-list">

The index page includes the list page, which we put in /lib instead of /www to designate that it's available for reuse by other packages.

You can test your work by viewing the page /myfirstpackage on your installation.

Create the add/edit page. If note_id is passed in, it display that note, and can change to edit mode if appropriate. Otherwise, it presents a form for adding notes.

[$OPENACS_SERVICE_NAME lib]$ cd /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/myfirstpackage/www
[$OPENACS_SERVICE_NAME www]$ emacs note-edit.tcl

ad_page_contract {
    This is the view-edit page for notes.

And the delete page. Since it has no UI, there is only a Tcl page, and no adp page.
