I have this code in odoo 16:
from odoo import models, fields, api
class AccountMove(models.Model):
_inherit = 'account.move'
def merge_invoice_lines(self):
for invoice in self:
lines_dict = {}
lines_to_remove = self.env['account\.move\.line'\]
\ \ \ \ \ \ for\ line\ in\ invoice\.invoice_line_ids:
\ \ \ \ \ \ \ \ if\ line\.product_id\.id\ in\ lines_dict:
\ \ \ \ \ \ \ \ \ \ \#\ If\ the\ product\ already\ exists,\ add\ the\ quantities\ and\ delete\ the\ original\ line\.
\ \ \ \ \ \ \ \ \ \ lines_dict\[line\.product_id\.id\]\.quantity\ \+=\ line\.quantity
\ \ \ \ \ \ \ \ \ \ lines_to_remove\ \+=\ line
\ \ \ \ \ \ \ \ else:
\ \ \ \ \ \ \ \ \ \ lines_dict\[line\.product_id\.id\]\ =\ line
\ \ \ \ \ \ \#\ Delete\ the\ original\ invoice\ lines
\ \ \ \ \ \ invoice\.invoice_line_ids\ \-=\ lines_to_remove
\ \ \ \ \ \ \#\ Add\ the\ merged\ lines\ back\ to\ the\ invoice
\ \ \ \ \ \ for\ product_id,\ line\ in\ lines_dict\.items\(\):
\ \ \ \ \ \ \ \ invoice\.invoice_line_ids\ \+=\ line
\ \ \ \ return\ True
and\ this\ in\ xml:
\ \
\ \ \ \
\ \ \ \ ir\.ui\.view">
\ \ \ \ \ \ account.invoice.form.merge.button
account.move
What I am trying to do is the following: I make 4 sales orders, the 4 orders have the same customer and the same products (which are 4 products, snacks, chocolates, juices, soft drinks) but with different quantities, I select the 4 sales orders. sale and I make an invoice in which the invoice shows me all the products that have the 4 sales orders only on the invoice, until then everything is fine... on the invoice there is a button to access the 4 sales orders where the invoice was generated, the method is called action_view_source_sale_orders, now, on the invoice when I click on the button called "Merge repeated lines", the products are merged without problem, BUT it alters the action_view_source_sale_orders button, because When I merge the repeated products of the invoice, in the other button where it shows the sales orders, instead of being 4 orders there are now 2... how can I prevent the action_view_source_sale_orders method from being altered?
