Hello ,
I created two module and one module with one to many relationship .
But in My module folder vardef.php file, Relationship array is blank . why
please suggest me any way to create relationship in this file .
For this reason my load_relationship returns null/empty
How did you create the relationship? In Studio?
If you created it in studio the extended vardefs will be inside a file in custom/Extension/modules/<your_module>/Ext/Vardefs/
You need to run a quick repair to combine the files using the extension framework before the changes will work.
