This documentation is still in progress. We are working hard to update all our screenshots to the new Magnolia 6 style. Please bear with us.
The tutorial consists of three pages:
- My first content app – This page, which describes the Bookshelf app.
- Part I - Creating a basic content app – Shows how to install Magnolia with Magnolia CLI and create the basic Bookshelf app from a content type definition.
- Part II - Fine-tuning a basic content app – Provides instructions to turn the basic app into the final and ready-to-use Bookshelf app.
Going through the tutorial you learn:
- How to define content types and use them to quickly create a content app.
- The basics of configuring fields and setting field validators.
- How to override configuration properties.
- How to make the elements of the app's UI ready for internationalization.
If you want to skip the tutorial and install the final app immediately, clone the repository containing the ready-made Bookshelf app as a light module directly into your Magnolia light module folder with the command:
Bookshelf app use case
The Bookshelf app you create in this tutorial is an example of content app. It is a simple book catalog allowing the user to store bibliographic data about each book: its title, the names of the author(s), publisher's name and the ISBN-13 number. The app also allows you to group selected book items into folders called shelves in the app.
What is a content app?
A Content app is a specialized app type for managing structured content. The content app user interface consists of a browser subapp and one or more detail subapps. Content apps make it easy to enter items such as products or events. Many native Magnolia apps such as Tours and Contacts are content apps. Because this app style is used often, the framework provides convenience classes to make building a content app faster.
Bookshelf app subapps
The Bookshelf app consists of two subapps.
In the Book Browser subapp, you can:
- Browse in the book catalog.
- Add, rename and delete books.
- Add, rename and delete shelves (folders for organizing books).
For each book item, the Bookshelf app stores and retrieves the following content properties:
- Short cataloging name (a required content property).
- Full book title.
- Author(s)' name(s).
- Whether the author(s) role is editorial or not.
- Book description.
- Publisher's name.
- ISBN-13 number.
Bookshelf app and Magnolia content types
The Bookshelf app is based on Magnolia content types. Expand the following link to see more details about the app's design parameters.
lib:book node type
books workspace, each book is a custom
lib:book node type defined for this tutorial.
Each book of the
lib:book type can have the following content properties:
|Property name||Usage||Data type||Restriction|
|Name(s) of the author(s) of the book.||String||none|
|The property to store the ||Boolean||none|
|Official book title.||String||none|
|Description of what the book is about.||String||5000 characters max.|
|Book publisher's name.||String||none|
|Date of publication of the book.||Date|
|International Standard Book Number in the 13-character variant.||String|
When you create an app from a content type definition, the
name property is generated automatically. Then the JCR node name is automatically deduced from the name.
We make use of this auto-generated
name property in the Bookshelf app by:
- Setting it to be a required property.
- Referring to it via the Cataloging name label in user dialogs.
Using it for creating a short and hyphenated book identifier (JCR node name) such as:
Therefore, in the Bookshelf app, the data in the Cataloging name field must be entered using the following syntax:
Magnolia automatically replaces the spaces with hyphens when creating a node name from the
Book data in the
books workspace and in the Book Detail subapp
Compare the following images, which show an example book item of type
lib:book and its various bibliographic data stored in the
books repository as seen through the interface of JCR Browser app (on the left), and the book data in the fields of the Book Detail subapp (on the right). Note especially the correspondences between the property names in the
books workspace and the fields in the Book Details tab:
On the next page, you create a basic Bookshelf app.
