[CanMik]

Module

sale_start_end_dates

Describe the bug

With Odoo 17, in the module sale_renting there is identical field "start_date", "end_date", these fields are datetime fields

To Reproduce

Affected versions: 17.0

Steps to reproduce the behavior:

1. Install sale_renting
2. Go into Renting module
3. Create a product that can be rented
4. Create a sale_order with a rentable product
5. You've got an error
   File "/usr/lib/python3/dist-packages/odoo/addons/sale_stock_renting/models/sale_order_line.py", line 98, in
   keyfunc = lambda line_id: (max(lines_grouping_key[line_id][0], now), lines_grouping_key[line_id][1], lines_grouping_key[line_id][2])
   TypeError: '>' not supported between instances of 'datetime.datetime' and 'bool'

Expected behavior
Chanege the type of start_date & end_date and complete compatibility with sale_renting module.

Forgot to mention that this module has a link with "Account Invoice Start End Dates".
In Odoo 17 there is two new fields that invalided the module "account_invoice_start_end_dates" -> deferred_start_date and deferred_end_sate.

So it needs to update this feature "Upon invoice creation, the values of the start/end dates of the sale order line are copied to the start/end dates of invoice lines."
