4. Scaffolding
• Based on the fields in in your domain class grails
generates views and controllers
• It also handles UI for basic operations like:
▫ Creation
▫ Read
▫ Update
▫ Delete
• For applying scaffold we just need to give the
following in the controller class
def scaffold = <Domain Class name>
8. Convention over Configuration
• Grails Follows convention over configuration
philosophy
▫ So we need to take care of the naming and the placement of
various files in the project
• So no need to write lot of XML files, thus faster
web dev
9. GORM
• Grails Object Relational Mapping
• Helps in the process of getting Objects in and
out from the database.
• We don’t need to care about writing SQL queries
for db operations
• It uses hibernate under the hood
10. MVC architecture
• Grails application has the most commonly used
Model-View-Controller Architecture
• It uses the spring MVC as underlying
framework
• When we create a grails application
using create-app, it makes a directory
structure in accordance with the MVC
11. Future Work
• Would try to compare Grails with other Java
based web development frameworks such as
Play, Spring MVC, struts etc.
