Play Framework Cookbook

Overview of this book

<p>The Play framework is the new kid on the block of Java frameworks. By breaking with existing standards the play framework tries not to abstract away from HTTP as most web frameworks do, but tightly integrates with it. This means quite a shift for Java programmers. Understanding these concepts behind the play framework and its impact on web development with Java are crucial for fast development of applications.<br /><br />The Play Framework Cookbook starts where the beginner documentation ends. It shows you how to utilize advanced features of the Play framework &ndash; piece by piece and completely outlined with working applications!<br /><br />The reader will be taken through all layers of the Play Framework and provided with in-depth knowledge from as many examples and applications as possible. Leveraging the most from the Play framework means to think simple again in a java environment. Implement your own renderers, integrate tightly with HTTP, use existing code, improve site performance with caching and integrate with other web services and interfaces. Learn about non-functional issues like modularity or integration into production and testing environments. In order to provide the best learning experience during reading Play Framework Cookbook, almost every example is provided with source code, so you can start immediately to integrate recipes into your own play applications.</p>

Adding security to the CRUD module


The CRUD module is the base of any rapid prototyping module. It helps you to administer data in the backend, while still being quick to create a frontend that closely resembles your prototype. For example, when creating an online shop, your first task is to create a nice looking frontend. Still it would be useful if you could change some things such as product name, description, or ID in the backend. This is where CRUD helps. However, there is no security inside the CRUD module, so anyone can add or delete data. This is where the secure module can help.

You can find the source code of this example in the chapter3/crud-secure directory.

Getting ready

You should already have added controllers for CRUD editing, as well as an infrastructure for authentication or at least something similar to a user entity. If you do not know about this part, you can read about it at http://www.playframework.org/documentation/1.2/crud.

How to do it...

You should have your own security...
