Grails integration allows performing dynamic queries for the domain class instances. So doing, code completion makes it possible to combine different queries based on the fields of the domain classes.
To create a dynamic query
- In a Grails domain class, declare fields to define mappings. For example, in the domain class
Book.groovythere are four fields:
Date acquired String title String author1 String author2
- In a Grails view, controller, or test class, create a method. For example, in the
BookTests.groovy, create method
- In the method body, reference a domain class to be queried, and start typing the query. Press Ctrl+Space:
- Press Ctrl+Space once more, and select the desired condition from
the suggestion list:
Repeat code completion to concatenate as many search conditions as required.
The same procedure applies to the count function:
