Py3o Report Engine

The py3o reporting engine is a reporting engine for Odoo based on
[Libreoffice](http://www.libreoffice.org/):
- 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 module report_py3o is the base module for the Py3o reporting
engine. If used alone, it will spawn a libreoffice process for each ODT
to PDF (or ODT to DOCX, ..) document conversion. This is slow and can
become a problem if you have a lot of reports to convert from ODT to
another format. In this case, you should consider the additionnal module
report_py3o_fusion_server which is designed to work with a libreoffice
daemon. With report_py3o_fusion_server, the technical environnement is
more complex to setup because you have to install additionnal software
components and run 2 daemons, but you have much better performances and
you can configure the libreoffice PDF export options in Odoo (allows to
generate PDF forms, PDF/A documents, password-protected PDFs,
watermarked PDFs, etc.).
This reporting engine is an alternative to
[Aeroo](https://github.com/aeroo-community/aeroo_reports): 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.
Table of contents
Install the required python libs:
:literal:`` 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:
:literal:`` apt-get –no-install-recommends install libreoffice``
For example, to replace the native invoice report by a custom py3o
report, add the following XML file in your custom module:
:literal:`` <?xml version=”1.0” encoding=”utf-8”?> <odoo> <record id=”account.account_invoices” model=”ir.actions.report”> <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.
:literal:`` <?xml version=”1.0” encoding=”utf-8”?> <odoo> <record id=”account.account_invoices” model=”ir.actions.report”> <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.
:literal:`` [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:
:literal:`` <?xml version=”1.0” encoding=”utf-8”?> <odoo> <record id=”account.account_invoices” model=”ir.actions.report”> <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:
:literal:`` <?xml version=”1.0” encoding=”utf-8”?> <odoo> <record id=”partner_summary_report” model=”ir.actions.report”> <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> <!– Add entry in “Print” drop-down list –> <field name=”binding_type”>report</field> <field name=”binding_model_id” ref=”base.model_res_partner”/> </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.
The templating language is [extensively
documented](http://py3otemplate.readthedocs.io/en/latest/templating.html),
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
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
o_format_lang(value, lang_code=False, digits=None, grouping=True,
monetary=False, dp=False, currency_obj=False, no_break_space=True)
Return a formatted numeric or monetary value according to the context
language and timezone
o_format_date(value, lang_code=False, date_format=False) Return a
formatted date or time value according to the context language and
timezone
## Sample report templates
Sample py3o report templates for the main Odoo native reports (invoice,
sale order, purchase order, picking, etc.) are available on the Github
project
[odoo-py3o-report-templates](https://github.com/akretion/odoo-py3o-report-templates).
- generate barcode ?
- add more detailed example in demo file to showcase features
- add migration guide aeroo -> py3o
