===========
Report Py3o
===========

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 developper to create or modify a report: the report is created and modified with Libreoffice. So this reporting engine has a fully WYSIWYG report developpment 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.

* 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 <https://github.com/aeroo/aeroo_reports>`_: these 2 reporting engines have similar features but their codes are completely different.

Installation
============

You must install 2 additionnal python libs:

.. code::

  pip install py3o.template
  pip install py3o.formats

To allow the conversion of ODT or ODS reports to other formats (PDF, DOC, DOCX, etc.), you must install several additionnal components and Python libs:

* `Py3o Fusion server <https://bitbucket.org/faide/py3o.fusion>`_,
* `Py3o render server <https://bitbucket.org/faide/py3o.renderserver>`_,
* a Java Runtime Environment (JRE), which can be OpenJDK,
* Libreoffice started in the background in headless mode,
* the Java driver for Libreoffice (Juno).

It is also possible to use the Python driver for Libreoffice (PyUNO), but it is recommended to use the Java driver because it is more stable.

The installation procedure below uses the Java driver. It has been successfully tested on Ubuntu 16.04 LTS ; if you use another OS, you may have to change a few details.

Installation of py3o.fusion:

.. code::

  pip install py3o.fusion
  pip install service-identity

Installation of py3o.renderserver:

.. code::

  pip install py3o.renderserver

Installation of Libreoffice and JRE on Debian/Ubuntu:

.. code::

  sudo apt-get install default-jre ure libreoffice-java-common libreoffice-writer

At the end, with the dependencies, you should have 6 py3o python libs:

.. code::

  % pip freeze | grep py3o
  py3o.formats==0.3
  py3o.fusion==0.8.6.dev1
  py3o.renderclient==0.2
  py3o.renderers.juno==0.7
  py3o.renderserver==0.5.1.dev1
  py3o.template==0.9.10.dev1
  py3o.types==0.1.1

Start the Py3o Fusion server:

.. code::

  start-py3o-fusion --debug -s localhost

Start the Py3o render server:

.. code::

  start-py3o-renderserver --java=/usr/lib/jvm/default-java/jre/lib/amd64/server/libjvm.so --ure=/usr/lib --office=/usr/lib/libreoffice --driver=juno --sofficeport=8997

On the output of the Py3o render server, the first line looks like:

.. code::

  DEBUG:root:Starting JVM: /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server/libjvm.so with options: -Djava.class.path=/usr/local/lib/python2.7/dist-packages/py3o/renderers/juno/py3oconverter.jar:/usr/lib/ure/share/java/juh.jar:/usr/lib/ure/share/java/jurt.jar:/usr/lib/ure/share/java/ridl.jar:/usr/lib/ure/share/java/unoloader.jar:/usr/lib/ure/share/java/java_uno.jar:/usr/lib/libreoffice/program/classes/unoil.jar -Xmx150M

After **-Djava.class.path**, there is a list of Java libs with *.jar* extension ; check that each JAR file is really present on your filesystem. On Ubuntu 16.04 LTS, the package *ure* installs several libs in another directory:

* /usr/lib/ure/share/java/juh.jar is located in /usr/share/java/juh.jar
* /usr/lib/ure/share/java/jurt.jar is located in /usr/share/java/jurt.jar
* /usr/lib/ure/share/java/ridl.jar is located in /usr/share/java/ridl.jar
* /usr/lib/ure/share/java/unoloader.jar is located in /usr/share/java/unoloader.jar
* /usr/lib/ure/share/java/java_uno.jar is located in /usr/share/java/java_uno.jar

To work around this problem, you can create a symlink:

.. code::

  sudo ln -s /usr /ure

and then use **--ure=/** instead of **--ure=/usr/lib** in the command line of *start-py3o-renderserver*.

To check that the Py3o Fusion server is running fine, visit the URL http://<IP_address>:8765/form. On this web page, under the section *Target format*, make sure that you have a line *This server currently supports these formats: ods, odt, docx, doc, html, docbook, pdf, xls.*.

Configuration
=============

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

.. code::

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

  <record id="account.account_invoices" model="ir.actions.report.xml">
      <field name="name">Invoice</field>
      <field name="model">account.invoice</field>
      <field name="report_name">account.report_invoice</field>
      <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*.

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

.. code::

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

  <record id="local_py3o_server" model="py3o.server">
      <field name="url">http://localhost:8765/form</field>
  </record>

  <record id="account.account_invoices" model="ir.actions.report.xml">
      <field name="name">Invoice</field>
      <field name="model">account.invoice</field>
      <field name="report_name">account.report_invoice</field>
      <field name="report_type">py3o</field>
      <field name="py3o_filetype">pdf</field>
      <field name="py3o_server_id" ref="local_py3o_server"/>
      <field name="module">my_custom_module_base</field>
      <field name="py3o_template_fallback">report/account_invoice.odt</field>
  </record>

  </odoo>
