Pagination in Groovy Grails

To implement pagination in a Groovy Grails application, you can use the paginate method provided by the Grails framework. This method allows you to retrieve a specific number of records from a database query result.

Here's an example of how to use the paginate method in Groovy Grails:

def results = Book.createCriteria().list(max: 10, offset: 20) {
    // Add any additional criteria or restrictions here
    // For example, you can add a where clause or order the results

// Access the paginated results
def books = results.results

In the above example, we use the createCriteria method to create a query for the Book domain class. We then use the list method with the max and offset parameters to specify the number of records to retrieve and the starting index of the records. The max parameter determines the maximum number of records to retrieve, and the offset parameter determines the starting index of the records.

You can also add additional criteria or restrictions to the query by using closures inside the createCriteria block.

After executing the query, you can access the paginated results using the results.results property.

Please note that the above example assumes you have a Book domain class defined in your Grails application. You may need to modify the code according to your specific domain class and query requirements.
