I want to generate a random value for every invoice I create, to use it as an access key for online payment of the invoice.

How can I accomplish the creation of this random value? The online payment part, displaying it on the invoice, and creating the payment I will be able to do just fine.

Hi,

You can use sequence for this purpose. Here is more details.

First you have to define "sequence type" and "sequence" as follows in xml file (better define a new xml file for sequence) :-

<openerp>

<data noupdate="1">

<!-- Sequences for purchase.order -->

<record id="seq_type_brand" model="ir.sequence.type">

<field name="name">Brand</field>

<field name="code">product.brand</field> # name of type

</record>

<record id="seq_brand" model="ir.sequence">

<field name="name">Brand</field>

<field name="code">product.brand</field> # name of type

<field name="padding">5</field>

<field name="number_next">50000</field> # first number

<field name="number_increment">1</field> # increment by

</record>

</data>

</openerp>

->here in "ir.sequence" you can use attribute like 'prefix' and 'suffix' if needed (number_next is starting number)

Then you can use get method (of ir.sequence) in defaults of field you want to generate sequence :-

Eg : test = fields.Char('Test', default = lambda obj: obj.env['ir.sequence'].get('product.brand') or '/')

or if you want to only generate the sequence when a record is saved, you can override the create function.

Hope this helps........
