How to create your own application

This first part introduces how to create an application with his code. Why do we have to create an application ? Because AnyBlok is just a framework not an application.

The goal is that more than one application can use the same database for different usage. The web server needs to give access to the user, but a profiler needs another access with another access rule, or another application needs to provide one part of the functionnalities.

We will write a simple application that connects to a new empty database:

  • Employee
    • name: employee’s name
    • office (Room): the room where the employee works
    • position: employee position (manager, developer...)
  • Room
    • number: describe the room in the building
    • address: postal address
    • employees: men and women working in that room
  • Address
    • street
    • zipcode
    • city
    • rooms: room list
  • Position
    • name: position name

Declare bloks in the entry points

A blok must be declared in a setuptools entry point named bloks.

File tree:

WorkBlok
└── setup.py

We declare 4 bloks in the setup.py file that we will define explain after:

bloks = [
    'office=exampleblok.office_blok:OfficeBlok',
    'employee=exampleblok.employee_blok:EmployeeBlok',
    'position=exampleblok.position_blok:PositionBlok',
    'employee-position=exampleblok.employee_position_blok:EmployeePositionBlok',
],

setup(
    # (...)
    entry_points={
        'bloks': bloks,
    },
)

Create Bloks

A blok contains Declarations such as:

  • Model: a Python class usable by the application and linked in the registry
  • Mixin: a Python class to extend Model
  • Column: a Python class, describing an sql column type
  • RelationShip: a Python class, allowing to surh on the join on the model data
  • ...

The blok name must be declared in the blok group of the setup.py file of the distribution as explain before.

And the blok must inherit the Blok class of anyblok in the __init__.py file of a package:

from anyblok.blok import Blok

class MyFirstBlok(Blok):
    """ This is valid blok """

The blok class must be in the init file of the package so that all modules and sub-packages which have declarations have to be imported by anyblok, in the import_declaration_module method

Employee blok

Some bloks can have requirements. Each blok define its dependencies:

  • required: required bloks must be loaded before
  • optional: If the blok exists, optional bloks will be loaded

A blok can be declared as autoinstall if the blok is not installed upon the loading of the registry, then this blok will be loaded and installed.

EmployeePosition blok:

Some bloks can be installed when other bloks are installed, they are called conditional bloks.

File tree:

employee_position_blok
├── __init__.py
└── employee.py

__init__.py file:

from anyblok.blok import Blok


class EmployeePositionBlok(Blok):

    version = '1.0.0'
    priority = 200

    conditional = [
        'employee',
        'position',
    ]

    def install(self):
        Employee = self.registry.Employee

        position_by_employee = {

                'position_name': position})

    def update(self, latest_version):

            self.install()

    @classmethod
    def import_declaration_module(cls):
        from . import employee  # noqa

Warning

There are no strong dependencies between conditional blok and bloks, so the priority number of the conditional blok must be bigger than bloks defined in the conditional list. Bloks are loaded by dependencies and priorities so a blok with small dependency/priority will be loaded before a blok with an higher dependency/priority.

Create Models

The Model must be added under the Model node of the declaration with the class decorator Declarations.register:

from anyblok import Declarations

@Declarations.register(Declarations.Model)
class AAnyBlokModel:
    """ The first Model of our application """

There are two types of Model:

  • SQL: Create a table in the database (inherit SqlBase and Base)
  • Non SQL: No table but the model exists in the registry and can be used (inherits Base).

SqlBase and Base are core models. Directly calling them is not allowed. But they are inheritable and each subclass is propagated to all the anyblok models. This example uses insert and multi_insert added by the anyblok-core blok.

An SQL model can define columns:

from anyblok import Declarations
from anyblok.column import String

register = Declarations.register
Model = Declarations.Model


@register(Model)
class ASQLModel:

    acolumn = String(label="The first column", primary_key=True)

Warning

Any SQL Model must have a primary key composed with one or more columns.

Warning

The table name depends on the registry tree. Here the table is asqlmodel. If a new model is defined under ASQLModel (example UnderModel: asqlcolumn_undermodel), the registry model will be stored as Model.ASQLModel.UnderModel

office_blok.office:

from anyblok import Declarations
from anyblok.column import Integer, String
from anyblok.relationship import Many2One

register = Declarations.register
Model = Declarations.Model


@register(Model)
class Address:

    id = Integer(label="Identifier", primary_key=True)
    street = String(label="Street", nullable=False)
    zip = String(label="Zip", nullable=False)
    city = String(label="City", nullable=False)

    def __str__(self):
        return "%s %s %s" % (self.street, self.zip, self.city)


@register(Model)
class Room:

    id = Integer(label="Identifier", primary_key=True)
    number = Integer(label="Number of the room", nullable=False)
    address = Many2One(label="Address", model=Model.Address, nullable=False,
                       one2many="rooms")

    def __str__(self):
        return "Room %d at %s" % (self.number, self.address)

The relationships can also define the opposite relation. Here the address Many2One relation also declares the room One2Many relation on the Address Model

A Many2One or One2One relationship must have an existing column. The column_name attribute allows to choose the linked column, if this attribute is missing then the value is “‘model.table’.’remote_column’” If the linked column does not exist, the relationship creates the column with the same type as the remote_column.

position_blok.position:

from anyblok import Declarations
from anyblok.column import String

register = Declarations.register
Model = Declarations.Model


@register(Model)
class Position:

    name = String(label="Position", primary_key=True)

    def __str__(self):
        return self.name

employee_blok.employee:

from anyblok import Declarations
from anyblok.column import String
from anyblok.relationship import Many2One

register = Declarations.register
Model = Declarations.Model


@register(Model)
class Employee:

    name = String(label="Number of the room", primary_key=True)
    room = Many2One(label="Office", model=Model.Room, one2many="employees")

    def __str__(self):
        return "%s in %s" % (self.name, self.room)

Updating an existing Model

If you create 2 models with the same declaration position and the same name, the second model will subclass the first model. The two models will be merged to get the real model

employee_position_blok.employee:

from anyblok import Declarations
from anyblok.relationship import Many2One

register = Declarations.register
Model = Declarations.Model


@register(Model)
class Employee:

    position = Many2One(label="Position", model=Model.Position, nullable=False)

    def __str__(self):
        res = super(Employee, self).__str__()
        return "%s (%s)" % (res, self.position)

Add entries in the argparse configuration

Some applications may require options. Options are grouped by category. And the application chooses the option category to display.

employee_blok.config:

from anyblok.config import Configuration


@Configuration.add('message', label="This is the group message")
def add_interpreter(parser, configuration):
    parser.add_argument('--message-before', dest='message_before')
    parser.add_argument('--message-after', dest='message_after')

Create an application

The application can be a simple script or a setuptools script. For a setuptools script, add this in the setup.py:

setup(
    ...
    entry_points={
        'console_scripts': ['exampleblok=exampleblok.scripts:exampleblok'],
        'bloks': bloks,
    },
)

The script must display:

  • the provided message_before
  • the lists of the employee by address and by room
  • the provided message_after

scripts.py:

import anyblok
from logging import getLogger
from anyblok.config import Configuration

logger = getLogger()


def exampleblok():
    # Initialise the application, with a name and a version number
    # select the groupe of options to display
    # return a registry if the database are selected
    registry = anyblok.start(
        'Example Blok', argparse_groups=['message', 'logging'])

    if not registry:
        return

    message_before = Configuration.get('message_before')
    message_after = Configuration.get('message_after')

    if message_before:
        logger.info(message_before)

    for address in registry.Address.query().all():
        for room in address.rooms:
            for employee in room.employees:
                logger.info(employee)

    if message_after:
        logger.info(message_after)

Display the help of your application:

The registry is loaded twice:

  • The first load installs the bloks anyblok-core, office, position and employee
  • The second load installs the conditional blok employee-position and runs a migration to add the field employee_name

The registry is loaded only once, because the bloks are already installed

Generic application of AnyBlok

Anyblok provides some console script to help :

  • anyblok_createdb

  • anyblok_updatedb

  • anyblok_interpreter .. note:

    if IPython is in the sys.modules then the interpreter is an IPython interpreter
    
  • anyblok_nose (nose test)

TODO: I know it’s not a setuptools documentation but it could be kind to show a complete minimalist exampe of setup.py with requires (to anyblok). We could also display the full tree from root

A direct link to download the full working example.

AnyBlok plugin for nosetests

You can test your bloks in your anyblok distribution with nose. use the option –with-anyblok-bloks. The plugin load the BlokManager et the RegistryManager after load the coverage plugin.

Create the configuration file

The configuration file allow to load all the initialisation variable:

[AnyBlok]
key = value

You can extend an existing config file:

[AnyBlok]
extend = ``path of the configfile``

The logging configuration are also loaded, see logging configuration file format:

[AnyBlok]
logging_configfile = ``name of the config file``
# json_logging_configfile = logging config file write with json
# yaml_logging_configfile = logging config file write with yaml

Default configuration file

You can define default system or user configuration file in fonction of your OS:

  • linux
    • system: /etc/xdg/AnyBlok/conf.cfg
    • user: /home/user name/.config/AnyBlok/conf.cfg
  • mac os x
    • system: /Library/Application Support/AnyBlok/conf.cfg
    • user: /Users/user name/Library/Application Support/AnyBlok/conf.cfg

Note

Works also for windows, See https://pypi.python.org/pypi/appdirs. The entry used are:

  • system: site_config_dir
  • user: user_config_dir

Theses configuration files are load before the specific configuration file. If the the configuration file does not exist then it will not raise error
