How would you display multiple dates in one field in case of multiple payments?

You should create a compute char field and fetch the payment date from the payment widget as follow:

import json

payment_date = fields.Char(compute='_compute_payment_date')

def _compute_payment_date(self):
    for inv in self:
        dates = []
        for payment_info in json.loads(inv.invoice_payments_widget).get('content', []):
            dates.append(payment_info.get('date', ''))
        inv.payment_date = ', '.join(dates)

This way you can fetch the payment date from the widget and add it to your field. This will work even if there will be multiple payments and that is why I have used CHAR field.

Hi,

You can try this code

payment_date = fields.Date(string='Payment Date',

                               compute='_compute_payment_date')

@api.depends('line_ids')

def _compute_payment_date(self):

    for rec in self:

        payment_dates = [inv.payment_id.payment_date for inv in rec.line_ids if inv.payment_id]

        rec.payment_date = payment_dates[0] if payment_dates else False

Am working on odoo 15 web studio, I have created a field (date) and include that in my Tree view and i created one 'automated action' for 'model journal entry', i set trigger for 'on update' and triggers field is 'payment status' and action to do is 'execute python code' this is what i did, I will give that code here :

all_records = env['account.move'].search([])

#model name -> env['account.move']
#to get all the records ->  .search([])

for rec in all_records:    
if rec.payment_state == 'paid':        
​if rec.invoice_payments_widget:
​ ​try:                
​ ​ ​# Parse the JSON string into a dictionary                ​ ​ ​ ​ ​
​ ​ ​invoice_payments_widget_dict = json.loads(rec.invoice_payments_widget)                                
​ ​ ​# Access the required information                
​ ​ ​content_list = invoice_payments_widget_dict.get('content', [])                                
​ ​ ​if content_list:                    
​ ​ ​ ​content_data = content_list[0]                    
​ ​ ​ ​date_str = content_data.get('date', '')                                        
​ ​ ​ ​if date_str:                        
​ ​ ​ ​ ​rec['x_studio_date_field_a1MrW'] = date_str            
​ ​except Exception:                
​ ​ ​rec['x_studio_date_field_a1MrW'] = None

from odoo import models, fields
import json


class AccountMove(models.Model):
    _inherit = 'account.move'
    _Inherit = 'account.payment'


    def _compute_payment_date(self):
        for inv in self:
            dates = []
            if isinstance(inv.invoice_payments_widget, bool):
                inv.payment_date = ''
                print('info 1', inv.payment_date)
            else:
                if inv.payment_state == 'paid' or inv.payment_state == 'partial':

                    for payment_info in json.loads(inv.invoice_payments_widget).get('content', []):
                        print('info 2 ', payment_info)
                        dates.append(payment_info.get('date', ''))
                        inv.payment_date = ', '.join(dates)
                        print(inv.payment_date)
                else:
                    inv.payment_date = ''
    payment_date = fields.Char(compute='_compute_payment_date')

You can add following in the account.inovice search view
