Report Py3o

The py3o reporting engine is a reporting engine for Odoo based on Libreoffice:

  • the report is created with Libreoffice (ODT or ODS),
  • the report is stored on the server in OpenDocument format (.odt or .ods file)
  • the report is sent to the user in OpenDocument format or in any output format supported by Libreoffice (PDF, HTML, DOC, DOCX, Docbook, XLS, etc.)

The key advantages of a Libreoffice based reporting engine are:

  • no need to be a developer to create or modify a report: the report is created and modified with Libreoffice. So this reporting engine has a full WYSIWYG report development tool!
  • For a PDF report in A4/Letter format, it’s easier to develop it with a tool such as Libreoffice that is designed to create A4/Letter documents than to develop it in HTML/CSS, also some print peculiarities (backgrounds, margin boxes) are not very well supported by the HTML/CSS based solutions.
  • If you want your users to be able to modify the document after its generation by Odoo, just configure the document with ODT output (or DOC or DOCX) and the user will be able to modify the document with Libreoffice (or Word) after its generation by Odoo.
  • Easy development of spreadsheet reports in ODS format (XLS output possible).

This reporting engine is an alternative to Aeroo: these two reporting engines have similar features but their implementation is entirely different. You cannot use aeroo templates as drop in replacement though, you’ll have to change a few details.

Installation

Install the required python libs:

pip install py3o.template
pip install py3o.formats

To allow the conversion of ODT or ODS reports to other formats (PDF, DOC, DOCX, etc.), install libreoffice:

apt-get --no-install-recommends install libreoffice

Configuration

For example, to replace the native invoice report by a custom py3o report, add the following XML file in your custom module:

<?xml version="1.0" encoding="utf-8"?>
<odoo>

<record id="account.account_invoices" model="ir.actions.report.xml">
    <field name="report_type">py3o</field>
    <field name="py3o_filetype">odt</field>
    <field name="module">my_custom_module_base</field>
    <field name="py3o_template_fallback">report/account_invoice.odt</field>
</record>

</odoo>

where my_custom_module_base is the name of the custom Odoo module. In this example, the invoice ODT file is located in my_custom_module_base/report/account_invoice.odt.

It’s also possible to reference a template located in a trusted path of your Odoo server. In this case you must let the module entry empty and specify the path to the template as py3o_template_fallback.

<?xml version="1.0" encoding="utf-8"?>
<odoo>

<record id="account.account_invoices" model="ir.actions.report.xml">
    <field name="report_type">py3o</field>
    <field name="py3o_filetype">odt</field>
    <field name="py3o_template_fallback">/odoo/templates/py3o/report/account_invoice.odt</field>
</record>

</odoo>

Moreover, you must also modify the Odoo server configuration file to declare the allowed root directory for your py3o templates. Only templates located into this directory can be loaded by py3o report.

[options]
...

[report_py3o]
root_tmpl_path=/odoo/templates/py3o

If you want an invoice in PDF format instead of ODT format, the XML file should look like:

<?xml version="1.0" encoding="utf-8"?>
<odoo>

<record id="account.account_invoices" model="ir.actions.report.xml">
    <field name="report_type">py3o</field>
    <field name="py3o_filetype">pdf</field>
    <field name="module">my_custom_module_base</field>
    <field name="py3o_template_fallback">report/account_invoice.odt</field>
</record>

</odoo>

If you want to add a new py3o PDF report (and not replace a native report), the XML file should look like this:

<?xml version="1.0" encoding="utf-8"?>
<odoo>

<record id="partner_summary_report" model="ir.actions.report.xml">
    <field name="name">Partner Summary</field>
    <field name="model">res.partner</field>
    <field name="report_name">res.partner.summary</field>
    <field name="report_type">py3o</field>
    <field name="py3o_filetype">pdf</field>
    <field name="module">my_custom_module_base</field>
    <field name="py3o_template_fallback">report/partner_summary.odt</field>
</record>

<!-- Add entry in "Print" drop-down list -->
<record id="button_partner_summary_report" model="ir.values">
    <field name="key2">client_print_multi</field>
    <field name="model">res.partner</field>
    <field name="name">Partner Summary</field>
    <field name="value" eval="'ir.actions.report.xml,%d'%partner_summary_report" />
</record>

</odoo>

Configuration parameters

py3o.conversion_command
The command to be used to run the conversion, libreoffice by default. If you change this, whatever you set here must accept the parameters --headless --convert-to $ext $file and put the resulting file into $file’s directory with extension $ext. The command will be started in $file’s directory.

Usage

Try me on Runbot

The templating language is extensively documented, the records are exposed in libreoffice as objects, on which you can also call functions.

Available functions and objects

user
Browse record of current user
lang
The user’s company’s language as string (ISO code)
b64decode
base64.b64decode
format_multiline_value(string)
Generate the ODF equivalent of <br/> and &nbsp; for multiline fields (ODF is XML internally, so those would be skipped otherwise)
html_sanitize(string)
Sanitize HTML string
time
Python’s time module
display_address(partner)
Return a formatted string of the partner’s address

Sample report templates

Sample py3o report templates for the main Odoo native reports (invoice, sale order, purchase order, picking, …) are available on the Github project odoo-py3o-report-templates.

Known issues / Roadmap

  • generate barcode ?
  • add more detailed example in demo file to showcase features
  • add migration guide aeroo -> py3o
