I've installed the Attachment module, that allow to attach filesto every module in odoo. The attachments are stored in db in the ir_attachment table. 


There is an entry for every attachment related to the id of the object, for example in the table I have:

res_model =account_invoice

res_id = 2886  (this is the id of the invoice)

index_content = 'image'



When I print the invoce I need to print also the image attached to the invoice.


Could you please give me an example of code to be used?

Try the following code if it works for you.

<t foreach="o.env['ir.attachment'].search([('res_id', '=', o.id), ('res_model', '=', 'account.invoice')])" t-as="attachment">
<span>
<img t-att-src="/web/image/ir.attachment/attachment.id/datas"/>
</span>

</t>

return compile(source, filename, mode, PyCF_ONLY_AST)
