Answer 1

You don't need to do any kind of override. Each currency record has this function builtin. If you have multi-currency setup then the order_id of purchase.requisition or the company or user should have the reference to currency. Decide which currency you want to use Or you can get the default currency id in qweb and call currency_id.amount_to_text(o.amount_total). Here currency_id is the reference to currency object.

Answer 2

I think the issue is understanding what model is represented by your line_ids.
Your report captures the object(s) it is representing as an object "o" for each object in the parameter "docs" which is passed to the report rendering function.
t-foreach="docs" t-as="o"
The report is now busy rendering as per your xml for the object "o" and is then iterating over each of the line_ids found within the object "o".
t-foreach="o.line_ids" t-as="line_ids"
I did not see what model each "line_ids" corresponded to however that model must have the function
def amount_to_text()
My suspicion is that your function is not in the proper model and if you want to execute the function you must move it to the correct model.

Answer 3

Dear Phillip thank you very much for your detailed reply.
The solution worked for me is like this and as I mentioned in my question I am using odoo 10.
Models.py :
# -*- coding: utf-8 -*-
from odoo import models, fields, api
import num2words
class purchase_requisition(models.Model):
_inherit = 'purchase.requisition'
def conv(self, val):
return num2words.num2words(val)
templates.xml :
<span t-esc="o.conv(total_value)" style="text-transform:uppercase;"/>

Answer 4

from odoo.tools import amount_to_text_en
amt_in_words = fields.Char(compute='set_amt_in_words')
def set_amt_in_words(self):
for each in self:
amount, currency = each.amount_total, each.currency_id.name
amount_in_words = amount_to_text_en.amount_to_text(amount, lang='en', currency=currency)
if currency == 'INR':
amount_in_words = str(amount_in_words).replace('INR', 'rupees')
amount_in_words = str(amount_in_words).replace('Cents', 'paise')
amount_in_words = str(amount_in_words).replace('Cent', 'paise')
amount_in_words += '\tonly'
each.amt_in_words = amount_in_words.title()
XML :
<span t-esc="o.amt_in_words"/>

Answer 5

#api.multi
def amount_to_text(self, amount, currency='INR'):
amount_in_words = amount_to_text_en.amount_to_text(amount, lang='en', currency=currency)
if currency == 'INR':
amount_in_words = str(amount_in_words).replace('INR', 'rupees')
amount_in_words = str(amount_in_words).replace('Cents', 'paise')
amount_in_words = str(amount_in_words).replace('Cent', 'paise')
amount_in_words += '\tonly'
return amount_in_words
def get_amount_in_words(self, amount):
amount_in_words = self.amount_to_text(amount)
return amount_in_words
and the xml -
