In this Laravel course, we will learn about the one to one polymorphic in Laravel.
Polymorphic relationships are a way to represent one-to-many relationships in Laravel. This means that the same type of model can be associated with many other models of the same type.
Polymorphic relationships can be defined in two ways:
1) Using a has-many relationship and defining a name for the related model type,
2) Using a belongs-to relationship and specifying which model it belongs to.
Polymorphic relationships are a type of relationship in the database that allows a table to store more than one type of data.
A one-to-one polymorphic relationship means that you have two tables, each with a column for the same type of data. For example, you might have an Orders table and an OrderDetails table.
The Orders table would have columns for order ID and order date. The OrderDetails table would also have columns for order ID and order date, but it would also have columns for product ID, quantity ordered, and price per item.
A one-to-many polymorphic relationship is when you have two tables with the same number of columns but different types of data in them.
For example, you might have an Orders table and an OrderDetails2 table. The Orders table has a column called "OrderID" which is an integer, and the OrderDetails2 table has columns called "OrderID", "OrderDate", and "Product" which are all string-based columns.
SELECT OrderID, OrderDate, Product FROM Orders LEFT JOIN OrderDetails2 ON Orders.OrderID = OrderDetails2.OrderID;Int | Date | Product
A one-to-one polymorphic relationship in Laravel Eloquent ORM is when two models share the same table. One model is used as a ‘parent’ and the other model is used as a ‘child’. The parent and child models are connected through their shared table.
One-to-one polymorphic relationships are useful when we want to store the same data in two different tables. We can use a one-to-one polymorphic relationship when a table has a column that is not unique.
