#When i run a migration and create all tables for the models below.
I run into the error when creating invoice and trying to add invoiceitem to that invoice
Error:"(1146, "Table 'defaultdb.invoices_invoice_items' doesn't exist")"

from enum import Enum
from tortoise import Model, fields

# --- Invoice Item Model ---**
class InvoiceItemModel(Model):
    id = fields.UUIDField(pk=True)
    item = fields.ForeignKeyField("models.ItemModel", related_name="invoice_items", on_delete=fields.CASCADE)
    totalAmount = fields.DecimalField(max_digits=10, decimal_places=2)
    quantity = fields.IntField()
    numInstalment = fields.IntField()
    paymentPlanPrice = fields.DecimalField(max_digits=10, decimal_places=2)
    description = fields.TextField(null=True)
    created_at = fields.DatetimeField(auto_now_add=True)
    updated_at = fields.DatetimeField(auto_now=True)

    def __str__(self):
        return self.item
    
    class Meta:
        table = "invoice_items"
        table_description = "Invoice Items Model"
        ordering = ["-created_at"]

# --- Invoice Status Model --- **
class InvoiceStatus(Enum):
    New = "New"
    Active = "Active"
    Overdue = "Overdue"
    Completed = "Completed"
    Cancelled = "Cancelled"
    Refund = "Refund"


# --- Invoice Model ---**
class InvoiceModel(Model):
    id = fields.UUIDField(pk=True)
    invoiceNumber = fields.CharField(max_length=255, unique=True)
    customer = fields.ForeignKeyField("models.CustomerModel", related_name="invoices", on_delete=fields.CASCADE)
    items = fields.ManyToManyField("models.InvoiceItemModel", related_name="invoices", through="invoices_invoice_items")
    vat = fields.DecimalField(max_digits=10, decimal_places=2)
    covidTax = fields.DecimalField(max_digits=10, decimal_places=2)
    totalAmount = fields.DecimalField(max_digits=10, decimal_places=2)
    subTotal = fields.DecimalField(max_digits=10, decimal_places=2)
    status = fields.CharEnumField(InvoiceStatus, default=InvoiceStatus.New)
    paymentType = fields.CharField(max_length=255)
    paymentPlanAmount = fields.DecimalField(max_digits=10, decimal_places=2)
    note = fields.TextField(null=True)
    overDueDate = fields.DatetimeField(null=True)
    setDate = fields.DatetimeField(null=True)
    created_at = fields.DatetimeField(auto_now_add=True)
    updated_at = fields.DatetimeField(auto_now=True)

    def __str__(self):
        return self.invoiceNumber
    
    class Meta:
        table = "invoices"
        table_description = "Invoice Model"
        ordering = ["-created_at"]

after manually creating "invoices_invoice_items" using the sql schema below

example:
"CREATE TABLE IF NOT EXISTS invoices_invoice_items (
invoice_id CHAR(36) NOT NULL,
invoice_item_id CHAR(36) NOT NULL,
CONSTRAINT fk_invoices_invoice_items_invoice_id FOREIGN KEY (invoice_id) REFERENCES invoices (id) ON DELETE CASCADE,
CONSTRAINT fk_invoices_invoice_items_invoice_item_id FOREIGN KEY (invoice_item_id) REFERENCES invoice_items (id) ON DELETE CASCADE,
PRIMARY KEY (invoice_id, invoice_item_id)
) CHARACTER SET utf8mb4 COMMENT='Join table for InvoiceModel and InvoiceItemModel';"

Now when i try to create an invoice after building all the tables. The new error i get is "(1054, "Unknown column 'invoices_id' in 'where clause'")"
