I am using Yii2 and have 3 related tables:
group (id, name)
entity (id, name, groupID); where groupID is FK to group.ID
register (id, date, entityID); where entityID is FK to entity.ID
[size="2"]N.B. I changed names and stripped tables for simplicity[/size]
In views/register/index.php I want to show in the gridview the fields:
entity.name is easily done, however, I am stuck with group.name
Can anyone help me please to solve that?
