Question

I’m developing a project, where there are two tables, region and district. In region I have:

+-------------+------------+------+-----+---------+----------------+
| Field       | Type       | Null | Key | Default | Extra          |
+-------------+------------+------+-----+---------+----------------+
| id          | bigint(20) | NO   | PRI | NULL    | auto_increment |
| name        | blob       | YES  |     | NULL    |                |
+-------------+------------+------+-----+---------+----------------+

and in district I have:

+-------------+------------+------+-----+---------+----------------+
| Field       | Type       | Null | Key | Default | Extra          |
+-------------+------------+------+-----+---------+----------------+
| id          | bigint(20) | NO   | PRI | NULL    | auto_increment |
| name        | blob       | YES  |     | NULL    |                |
| region_id   | bigint(20) | NO   | MUL | NULL    |                |
+-------------+------------+------+-----+---------+----------------+

In the District view, The name of the district gets displayed, but not the Region name:

Id  1
Name    Community College
Description Community College
Homepage    
Logo    
Region  ctv.Region : 1
Streams 

This is the show in the DistrictController:

def show = {
        def districtInstance = District.get(params.id)

        if(!districtInstance){
            flash.message = "${message(code: 'default.not.found.message', args: [message(code: 'district.label', default: 'District'), params.id])}"
            redirect(action : "list")
        }
        else{
            [districtInstance : districtInstance]
        }
    }

How can I modify my show closure in other to instead of displaying the Region.id I have the region.name instead?
Thanks

I assume you are just using the scaffolding? So try overriding toString() in Region, eg

public String toString() {
   name
}
