Error in foreign key through 2 tables
krumld opened this issue · comments
Hi,
i'm trying to set through column for addColumnText.
I wrote QueueGrid and I need get column with environment name.
My code:
$grid->addColumnText('environment_id', 'Environment', 'file.environment.name')->setFilterText('file.environment.name');
I'm getting this error:
Cannot read an undeclared column 'file.environment.name'
If I change third parameter of addColumnText to 'file.environment:file_id', there is no error. But datagrid doesn't generate LEFT JOIN in SQL.
It generates LEFT JOIN only when filtering environment name.
My question: Why does the 'file.environment.name' in filter generates LEFT JOIN, but same relation in through column throws error?
Is there possibility to create relation over 2 tables?
My tables:
queue
- id
- file_id
- ...
file
- id
- environment_id
- ...
environment
- id
- name
- ...
