Hello,

I've added in the form view for the invoices additional filed "Total In Words".

See picture:

I've also written following piece of code

from openerp import tools
from openerp.osv import fields, osv
from openerp.tools.translate import _
from tools.translate import _
from tools.amount_to_text_en import amount_to_text

#Import the logger for debug code
import logging
_logger = logging.getLogger(__name__)

class account_invoice(osv.osv):
    _inherit = 'account.invoice'
    _columns = {
                'zTotalInWords': fields.char('Total In Words', size=100, readonly=True, states={'draft': [('readonly', False)]}),                
                }   

    def onchange_amount(self, cr, uid, ids, amount):
        text_amount = amount_to_text_en.amount_to_text(amount, 'en', 'EURO')
        _logger.debug(self, 'zFS_account_invoice:account_invoice: amount: %s; text_amount: %s', amount, text_amount)
        return {'value': {'zTotalInWords': text_amount}}

and created following xml file

<?xml version="1.0" encoding="utf-8"?> <openerp>
    <data>      <record id="zinvoice_form" model="ir.ui.view">
            <field name="name">account.invoice.form.inherited</field>
            <field name="model">account.invoice</field>
            <field name="inherit_id" ref="account.invoice_form"/>          

            <field name="arch" type="xml">
                <field name="amount_total" position="replace">
                    <field name="amount_total" on_change="onchange_amount(amount_total)" class="oe_subtotal_footer_separator" widget="monetary" options="{'currency_field': 'currency_id'}"/>       
                </field>
                <field name="amount_tax" position="after">
                    <field name="zTotalInWords"/>
                </field>                      
            </field>
        </record>            
    </data> </openerp>

Still, I don't get my logger.info message in the server log and the field does not get updated automatically and I don't get error... I suspect that the event is not fired at all so my py code is not executed... Same when I hit the "update" button, which updates the total price in numbers...

What did I do wrong and how to fix it?

I don't think that total has a onchange method since it's a function field. Maybe you can override the function.

Hi Grover, have you seen some docu or examples on that? I'm not sure I understand your proposal... My understanding is that I can add an OnChange method via mu zinvoice_form in the XML file. Thank you! Regards, Pavel

Hi Pavel,

To convert amount to text, you can use the amount_to_text method defined in openerp/tools/amount_to_text_en.py

Create a field which will store text value of amount. You can either create char or text field.

 'text_amount': fields.char("TextAmount", size=100)

or

'text_amount': fields.text("Text Amount")

Now write a on_change method which will be called when you change the value of amount field. First add on_change in your xml where your amount field is.

Like this:

<field name="your_amount_field" on_change="onchange_amount(your_amount_field)"/>

Write the following code inside your class in your py:

from openerp.tools import amount_to_text_en

def onchange_amount(self, cr, uid, ids, amount):
    text_amount = amount_to_text_en.amount_to_text(amount, 'en', 'EURO')
    return {'value': {'text_amount': text_amount}}

This solution is suggested by Sudhir Arya

Hi Pavel, You should not define on_change on function field, it will not be called. For your scenario you should override the function which is called to count 'amount_total'. Want to add one more thing the value fetched from on_change can't be saved b'coz you have field with readonly attributes. Values with readonly attribute didn't get in vals on 'write' method.

Thanks, Ajay Chauhan
