How to connect button with function?

Avatar

Hi everyone.

I'm trying to put a new button on sales invoice which will print my customized version of invoice. So I've created new addon"my" and now need to connect this button click with function in "my" module. Can you please suggest, how can I refernce function in my model when hitting my new print button. The "print_invoice_my" refers to account.invoice model, while it should refernce to "my" model. Therefore I get an error when trying to run, it says it can not find  "print_invoice_my" in account.invoice.Here is my xml:

<openerp>
<data>
<record id="invoice_form_my" model="ir.ui.view">
<field name="name">account.invoice.form.my</field>
<field name="model">account.invoice</field>
<field name="inherit_id" ref="account.invoice_form"/>
<field name="arch" type="xml">
<button name="invoice_print" position="after">
<button type="object" name="print_invoice_my" string="my Invoice"/>
</button>
</field>
</record>
</data>
</openerp>

Much thanks, Arcull

Hi Arcull,


Make sure you have the method or definition with this name print_invoice_my inside your account.invoice model,

When your button type="object" that means odoo framework will look for the method inside model provided on same view, with button name value.



Hope this might help


Regards,

Anil.

Thanks Anil. I don't want to modify existing model. I will inherit account.invoice model, but don't know how will my xml for custom invoice then look like? I mean the tags:model and inherit_id. Thanks for your help.

You've to define print_invoice_my python function in account.invoice model, because of name="print_invoice_my" the function with name print_invoice_my from the corresponding model (account.invoice in your case) is being called and as you have not defined it, you've got above error.



UPDATE:

if you're interested in changing view of report itself, or add additional fields to it, then you should inherit or change the report view defined here: https://github.com/odoo/odoo/blob/dc48744bf7438761e1f25d411ec61755f74c60df/addons/account/views/report_invoice.xml#L4


for example, if you add new field in account.invoice, named my_field, then something like this should do the trick:

<template id="report_invoice_document" inherit_id="account.report_invoice_document">

<xpath expr="//div/div/div/address" position="after">

<span t-field="o.my_field" /> 

</xpath> </template>

this way, "my_field" is added to the printed invoice.

Thanks Temur, but the point is, that I don' want to adjust the original account.invoice model, I want to inherit it in my module and add the function there. How can I achieve that? Thanks again.

So mean I. It's correct, you must inherit account.invoice model in your module and define your function print_invoice_my in the inherited model, but you're actually extending the existing account.invoice model, and so defining function in it. I just skipped over the details in my answer

Thanks Temur. Will do that, but how will my xml for custom invoice then look like? I guess account.invoice will change to my. What about the "inherit_id" tag? Thanks.

No, there is nothing to change in XML, account.invoice will stay same because you'll extend the account.invoice model by "Extension" inheritance, see documentation at https://www.odoo.com/documentation/8.0/reference/orm.html#inheritance-and-extension , there is explanation of a different inheritance approach, you'll need to apply the "Extension" one (scroll down a bit at the referred page); "inherit_id" refers to the XML record you're extending in your xml, it does not need to be changed either.

Unfortunatelly I can't make the inheritance to work. Please see my post at https://www.odoo.com/forum/help-1/question/cant-inherit-account-invoice-96458

Answered... We do not use _name or we use same _name as in a parent class in case of extension inheritance.
