Object of type Decimal is not JSON serializable

[yubarajshrestha]

Describe the bug
If you have decimal migrations then you can't return response.

Migration

def up(self):
        """
        Run the migrations.
        """
        with self.schema.create("commerce_products") as table:
            table.increments("id")
            table.string("title")
            table.string("slug").unique()
            table.decimal("price", 19, 2)
            table.timestamps()

Modal

class Product(Model):
    __fillable__ = ["title", "slug", "price"]

Controller

class ProductController(Controller):
    def __init__(self, response: Response, request: Request) -> None:
        self.response = response
        self.request = request

    def index(self):
        """Returns a list of products"""

        per_page = int(self.request.input("per-page", 10))
        page = int(self.request.input("page", 1))

        return  Product.paginate(per_page, page)

Expected behavior
I should see a proper json response

The fix to this is to cast the decimal to a float in the model:

class CommerceProducts(Model):

    __casts__ = {
        "price": "float"
    }
