Today I will explain how you can use our extension "Link Multiple Pro" with many-to-Many (n:n) relationships.
In this article we assume the following entities Order & Product, and we need to add link n:n between them.
Create the middle entity manually.
Dont create n:n relationship directly using the entity manager
You can name this middle entity any name but we prefer one of these patterns: - OrderProduct (I will choose this name) - OrderItem - OrderProductItem - OrderProductMiddle
To make this more real we will add 2 fields to the middle entity: - Price - Quantity
Go to #Admin/linkManager/scope=OrderProduct (OrderProduct/relationships) add these two links: - Order has many OrderProduct - Product has many OrderProduct
Go to: Admin > Entity Manager > Order > fields > orderProducts:
In the fields options do these:
Select List Small layout or just fill the next input with the fields you want to display on the list. NOTE: if you have "Layout Pro" I prefer to create a new list layout and select it here.
Here is the most important step set the "Middle Link" to "Product".
Other settings are optional
Save and add the orderProducts field to the Order detail layout.
add price & entity to the OrderProduct selected list layout (Optional).
You are done!
