Make your Odoo scripts sing.

Project description

https://travis-ci.org/camptocamp/anthem.svg?branch=master

Anthem is a tool to help scripting Odoo instances for automated setup, upgrades, testing and more.

It should be an alternative to the other tools like oerpscenario.

Make your own songs

Writing your songs is as easy as creating a Python Package. The songs functions called by anthem must have a positional ctx argument.

ctx is essentially the execution context - you can access ctx.env from it, which is an Odoo environment instance that you should be pretty much familiar with.

## songs/install.py

def setup_company(ctx):
    """ Setup company """
    company = ctx.env.ref('base.main_company')
    company.name = 'My Company'


def main(ctx):
    setup_company(ctx)

Logs

A song can display some logs when executed with @anthem.log, Context.log and Context.log_line.

import anthem

@anthem.log
def setup_company(ctx):
    """ Setting up company """
    company = ctx.env.ref('base.main_company')
    with ctx.log('Changing name'):
        company.name = 'My Company'
        ctx.log_line('Name changed')
    with ctx.log('Loading a logo'):
        company.logo = b64encode(LOGO_CONTENT)
        ctx.log_line('Logo changed')

The decorator on the function will display the first line of the docstring. Both the decorator and the context manager will show the timing of the execution. The upper example gives:

Execute your songs

Use the command line anthem. Provided your songs and openerp are in the PYTHONPATH:

Anthem will execute the function main of the module songs.install with a ctx initialized with an Odoo env.

Instead of using -c for the command line, you can export the environment variable OPENERP_SERVER with the path of the configuration file.

In order to have openerp in the PYTHONPATH, you might install it as a package with pip install -e or directly modify the PYTHONPATH.

In order to have your songs in the PYTHONPATH, the better is to make a Python package out of them.

Testing

Dependencies

To run the tests, you must have Postgresql running, with accesses for your user (or you will have to modify tests/config/odoo.cfg with your database username and password).

Run the tests

To run anthem’s tests, it is a good idea to do an editable install of it in a virtualenv. You must also prepare the environment by installing odoo packages.

Odoo 9.0 (Python 2):

Odoo 10.0 (Python 2):

Odoo 11.0 (Python 3):

If need be, you can drop the test database with (adapt the version):

These steps will download the nightly release of Odoo install it as a package then install a database, so tests can be run against it (and that’s also why it is important to use a virtualenv!)

When calling pytest, you have to define the OPENERP_SERVER environment variable with the configuration file for the Odoo database that will be used for the tests.

Lyrics

Lyrics are predefined snippets written for the most commonly used cases, like:

Loading data

There’s an ability to supply data in a handy CSV format - Anthem is just able to parse and load those. load_csv method is meant to be the main entrypoint for doing so:

Param Description
ctx Anthem context instance
model Odoo model name or model klass from ctx.env
path absolute or relative path to CSV file. If a relative path is given you must provide a value for ODOO_DATA_PATH in your environment or set --odoo-data-path option.
header whitelist of CSV columns to load
header_exclude blacklist of CSV columns to ignore
fmtparams keyword params for csv_unireader

CSV format is similar to that of an Odoo export format, namely: * it should contain a set of field names in a header * each consecutive row defines a set of values to use to create records on a given model

Records

This section is dedicated to methods that operate on records.

Provide XMLIDs for records

This is as simple as calling anthem.records.add_xmlid with a record as a first parameter and a desired XMLID as a second.

E.g., you have a very special res.partner record foo:

from anthem.records import add_xmlid

[...]
@anthem.log
def add_xmlid_to_foo(ctx):
    """Make Jhony Foo great again."""
    foo = ctx.env['res.partner'].create({
        'name': 'Jhony',
        'lastname': 'Foo',
    })
    add_xmlid(foo, '__setup__.res_partner_foo_jhony')

From now on, Jhony could be referred to as ctx.env.ref('__setup__.res_partner_foo_jhony').

Upserting a record

“Upsert” is a commonly used term that basically stands for UPDATE or INSERT. Anthem features a facility that is capable of executing that kind of operations on Odoo databases. There is a method called anthem.records.create_or_update that relies on the model, a set of values and a record XMLID.

If your goal is to create the record in the first place as well as provide an XMLID, as was shown in a previous section, create_or_update does just what you need.

Example
from anthem.records import create_or_update

[...]
@anthem.log
def create_partner_foo(ctx):
    """Ensure that Jhony Foo is known to our Company."""
    create_or_update(
        ctx,
        model='res.partner',
        xmlid='__setup__.res_partner_foo_jhony',
        values={
            'name': 'Jhony',
            'lastname': 'Foo',
        }
    )

Upon calling, it would:

  • Try to fetch the record by a given XMLID
  • If the record was found:
    • Update it with the given values (call record.update(values) on it)
  • Otherwise:
    • Create a record with given values (call model.create(values))
    • Provide an XMLID to it (using anthem.records.add_xmlid)
  • In any case: return that record back

Modules

This section is dedicated to methods that operate on modules.

Uninstalling a module(s)

Sometimes you just need some particular module to be gone from your instance(s) and you’d like it done programmatically, without having to reach for each instance, search for it and hit the “Uninstall” button. Anthem can do the job for you: you can simply call an anthem.lyrics.modules.uninstall with a list of module names that you won’t use anymore.

Example (given that there are modules foo and bar that you want gone):
from anthem.lyrics.modules import uninstall

[...]
@anthem.log
def uninstall_foo(ctx):
    """Get rid of legacy `foo` and `bar`."""
    uninstall(['foo', 'bar'])

Updating translations on module(s)

In a similar fashion, sometimes you need to update translations on a set of modules - anthem.lyrics.modules.update_translations is there for you :wink:

Example is similar to the previous case - just call the different method instead.

Updating module configuration

By using this feature, you’re able to preconfigure your module setup via Anthem song: you’ll just need a straight idea what needs to be done, an instance of a configuration settings model for your module (model name will do as well) and a mapping (in a form of Python dictionary) of technical configuration names with desired values.

Here’s a brief example of sale module configuration:

from anthem.lyrics import settings

[...]
@anthem.log
def define_sale_settings(ctx):
    """Configure `sale` module."""
    model = ctx.env['sale.config.settings']
    # it's okay to use 'sale.config.settings' as a string though
    model = 'sale.config.settings'
    settings(ctx, model, {
        'default_invoice_policy': 'delivery',
        ...: ...,
        'et': 'cetera',
    })

Be advised: settings onchange are not triggered by this function.

Usage within Marabunta

Anthem and Marabunta are powerful when combined: you can call a set of songs inside Marabunta’s migration steps using following syntax:

...
- version: 10.0.1.0.0
  operations:
    pre:
      - anthem songs.upgrade.your_pre_song::main
    post:
      - anthem songs.upgrade.your_post_song::main

By using this approach, you possess the power of full-pledged Odoo Environment instance initialized on a live database while performing a regular upgrade powered by Marabunta.

Let’s say that you have to enable multicompany with inter-company transactions on a migration to next version, lets say, 10.0.1.1.0. In this case, you’ll need a song to back this up on a Python side first:

# songs.upgrade.upgrade_10_0_1_1_0.py
from anthem.lyrics import settings

[...]
@anthem.log
def enable_multicompany(ctx):
    """Set up multicompany."""
    settings(ctx, 'base.config.settings', {
        # enable multicompany as it is
        'group_light_multi_company': True,
        # enable inter-company transactions
        'module_inter_company_rules': True,
    })

 [...]
 @anthem.log
 def main(ctx):
     enable_multicompany(ctx)

And then you’ll need to call it on a migration step:

...
- version: 10.0.1.1.0
  operations:
    post:
      - anthem songs.upgrade.upgrade_10_0_1_1_0::main

Boom! Enjoy your new multicompany settings.

That’s all, folks!

Thanks for reading. Happy hacking and enjoy your songwriting skills!
