Membuat Odoo attachment otomatis di Odoo 10 dan 11

Biasanya untuk membuat Odoo attachment (tautan) kita harus melakukan upload manual pada sebuah record di Odoo. Tapi kita juga bisa membuat attachment secara otomatis berdasarkan sebuah report.

Antara Odoo 10 dan Odoo 11 terdapat perbedaan dalam membuat attachment dari sebuah report. Bukan hanya karena perbedaan versi python, tetapi karena seperti yang diketahui, di Odoo 11 sudah tidak ada modul report seperti yang ada pada Odoo 10.

Sebelum memulai pastikan bahwa modul document sudah terinstal.

Anggap saja kita mempunyai model awal sebagai berikut.

from odoo import models, fields, api

class SomeModel(models.Model):
    _name = 'some.model'

    field1 = fields.Char(string="Field 1")
    field2 = fields.Boolean(string="Field 2")

    @api.multi
    def action_generate_attachment(self):
        """ this method called from button action in view xml """
        pass

Untuk view xml sebagai berikut.

<odoo>
    <record model="ir.ui.view" id="view_some_model_form">
        <field name="name">some.model.form</field>
        <field name="model">some.model</field>
        <field name="arch" type="xml">
            <form>
                <header>
                    <button name="action_generate_attachment" string="Generate Attachment" type="object"/>
                </header>
                <!--
                    Other view stuff
                -->
            </form>
        </field>
    </record>
</odoo>

Dan sebuah template report seperti ini.

<odoo>
    <report id="some_report_id"
        model="some.model"
        string="Some Model Report"
        report_type="qweb-pdf"
        name="some_report_name"
        file="some_report_file"
        menu="False"/>

    <template id="some_report_name">
        <t t-foreach="docs" t-as="doc">
            <!--
                Other report stuff
            -->
        </t>
    </template>
</odoo>

Sekarang kita akan memodifikasi action_get_attachement untuk menghasilkan attachment berdasarkan Odoo 10 dan Odoo 11.

Generate Odoo attachment di Odoo 10.

import base64
from odoo import models, fields, api

class SomeModel(models.Model):
    _name = 'some.model'

    field1 = fields.Char(string="Field 1")
    field2 = fields.Boolean(string="Field 2")

    @api.multi
    def action_generate_attachment(self):
        """ this method called from button action in view xml """
        # generate pdf from report, use report's report_name as params for get_pdf
        REPORT_NAME = 'some_report_name'
        pdf = self.env['report'].get_pdf(self.ids, REPORT_NAME)
        b64_pdf = base64.encodestring(pdf)
        
        # save pdf as attachment
        ATTACHMENT_NAME = "My Attachment Name"
        return self.env['ir.attachment'].create({
            'name': ATTACHMENT_NAME,
            'type': 'binary',
            'datas': b64_pdf,
            'datas_fname': ATTACHMENT_NAME + '.pdf',
            'store_fname': ATTACHMENT_NAME,
            'res_model': self._name,
            'res_id': self.id,
            'mimetype': 'application/x-pdf'
        })

Generate Odoo attachment di Odoo 11.

import base64
from odoo import models, fields, api

class SomeModel(models.Model):
    _name = 'some.model'

    field1 = fields.Char(string="Field 1")
    field2 = fields.Boolean(string="Field 2")

    @api.multi
    def action_generate_attachment(self):
        """ this method called from button action in view xml """
        # generate pdf from report, use report's id as reference
        REPORT_ID = 'some_report_id'
        pdf = self.env.ref(REPORT_ID).render_qweb_pdf(self.ids)
        # pdf result is a list
        b64_pdf = base64.b64encode(pdf[0])
        
        # save pdf as attachment
        ATTACHMENT_NAME = "My Attachment Name"
        return self.env['ir.attachment'].create({
            'name': ATTACHMENT_NAME,
            'type': 'binary',
            'datas': b64_pdf,
            'datas_fname': ATTACHMENT_NAME + '.pdf',
            'store_fname': ATTACHMENT_NAME,
            'res_model': self._name,
            'res_id': self.id,
            'mimetype': 'application/x-pdf'
        })
