Front Matter
============
Information about the AnyBlok / Marshmallow project.
Project Homepage
----------------
AnyBlok is hosted on `github <http://github.com>`_ - the main project
page is at https://github.com/AnyBlok/AnyBlok_Marshmallow. Source code is
tracked here using `GIT <https://git-scm.com>`_.
Releases and project status are available on Pypi at
http://pypi.python.org/pypi/anyblok_marshmallow.
The most recent published version of this documentation should be at
http://doc.anyblok-marshmallow.anyblok.org.
Project Status
--------------
AnyBlok with Marshmallow is currently in beta status and is expected to be fairly
stable. Users should take care to report bugs and missing features on an as-needed
basis. It should be expected that the development version may be required
for proper implementation of recently repaired issues in between releases;
Installation
------------
Install released versions of AnyBlok from the Python package index with
`pip <http://pypi.python.org/pypi/pip>`_ or a similar tool::
pip install anyblok_marshmallow
Installation via source distribution is via the ``setup.py`` script::
python setup.py install
Installation will add the ``anyblok`` commands to the environment.
Unit Test
---------
Run the test with ``pytest``::
pip install pytest pytest-cov
ANYBLOK_DRIVER_NAME=postgres ANYBLOK_DATABASE_NAME=mybase pytest anyblok_marshmallow/tests
Dependencies
------------
AnyBlok works with **Python 3.6** and later. The install process will
ensure that `AnyBlok <http://doc.anyblok.org>`_,
`marshmallow >= 3.2.0 <https://marshmallow.readthedocs.io/en/latest/>`_ and
`marshmallow-sqlalchemy <https://marshmallow-sqlalchemy.readthedocs.io/en/latest/>`_
are installed, in addition to other dependencies.
The latest version of them is strongly recommended.
Contributing (hackers needed!)
------------------------------
Anyblok / Marshmallow is at a very early stage, feel free to fork, talk with core
dev, and spread the word!

Memento
=======
Declare your **AnyBlok model**
------------------------------
::
from anyblok.column import Integer, String
from anyblok.relationship import Many2One, Many2Many
from anyblok import Declarations
@Declarations.register(Declarations.Model)
class City:
id = Integer(primary_key=True)
name = String(nullable=False)
zipcode = String(nullable=False)
def __repr__(self):
return '<City(name={self.name!r})>'.format(self=self)
@Declarations.register(Declarations.Model)
class Tag:
id = Integer(primary_key=True)
name = String(nullable=False)
def __repr__(self):
return '<Tag(name={self.name!r})>'.format(self=self)
@Declarations.register(Declarations.Model)
class Customer:
id = Integer(primary_key=True)
name = String(nullable=False)
tags = Many2Many(model=Declarations.Model.Tag)
def __repr__(self):
return '<Customer(name={self.name!r}, '
'tags={self.tags!r})>'.format(self=self)
@Declarations.register(Declarations.Model)
class Address:
id = Integer(primary_key=True)
street = String(nullable=False)
city = Many2One(model=Declarations.Model.City, nullable=False)
customer = Many2One(
model=Declarations.Model.Customer, nullable=False,
one2many="addresses")
.. warning::
The **AnyBlok model** must be declared in a blok
Declare your schema
-------------------
::
from anyblok_marshmallow import SchemaWrapper, PostLoadSchema, Nested
class CitySchema(SchemaWrapper):
model = 'Model.City'
class TagSchema(SchemaWrapper):
model = 'Model.Tag'
class AddressSchema(SchemaWrapper):
model = 'Model.Address'
class Schema:
# Add some marshmallow fields or behaviours
# follow the relationship Many2One and One2One
city = Nested(CitySchema)
class CustomerSchema(SchemaWrapper):
model = 'Model.Customer'
# optionally attach an AnyBlok registry
# to use for serialization, desarialization and validation
registry = registry
class Schema(PostLoadSchema):
# follow the relationship One2Many and Many2Many
# - the many=True is required because it is *2Many
# - exclude is used to forbid the recurse loop
addresses = Nested(AddressSchema, many=True, exclude=('customer', ))
tags = Nested(TagSchema, many=True)
customer_schema = CustomerSchema()
.. note::
**New** in version **1.1.0** the Nested field must come from **anyblok_marshmallow**,
because **marshmallow** cache the Nested field with the context. And the context is not propagated
again if it changed
.. note::
**Ref** in version **1.4.0**, ``post_load_return_instance`` was replaced by the mixin class
``PostLoadSchema``
.. note::
**Ref** in version **2.1.0**, ``ModelSchema`` was replaced by ``SchemaWrapper``. This action
break the compatibility with the previous version, but allow to follow the upgrade of **marshmallow**
(De)serialize your data and validate it
---------------------------------------
::
customer = registry.Customer.insert(name="JS Suzanne")
tag1 = registry.Tag.insert(name="tag 1")
customer.tags.append(tag1)
tag2 = registry.Tag.insert(name="tag 2")
customer.tags.append(tag2)
rouen = registry.City.insert(name="Rouen", zipcode="76000")
paris = registry.City.insert(name="Paris", zipcode="75000")
registry.Address.insert(customer=customer, street="Somewhere", city=rouen)
registry.Address.insert(customer=customer, street="Another place", city=paris)
dump_data = customer_schema.dump(customer).data
# {
# 'id': 1,
# 'name': 'JS Suzanne',
# 'tags': [
# {
# 'id': 1,
# 'name': 'tag 1',
# },
# {
# 'id': 2,
# 'name': 'tag 2',
# },
# ],
# 'addresses': [
# {
# 'id': 1
# 'street': 'Somewhere'
# 'city': {
# 'id': 1,
# 'name': 'Rouen',
# 'zipcode': '76000',
# },
# },
# {
# 'id': 2
# 'street': 'Another place'
# 'city': {
# 'id': 2,
# 'name': 'Paris',
# 'zipcode': '75000',
# },
# },
# ],
# }
customer_schema.load(dump_data).data
# <Customer(name='JS Suzanne' tags=[<Tag(name='tag 1')>, <Tag (name='tag 2')>])>
errors = customer_schema.validate(dump_data)
# dict with all the validating errors
.. note::
We have an instance of the model cause of the mixin ``PostLoadSchema``
Give the registry
-----------------
The schema need to have the registry.
If no registry found when the de(serialization) or validation then the
**RegistryNotFound** exception will be raised.
Add the **registry** by the class attribute
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is the solution given in the main exemple::
class CustomerSchema(SchemaWrapper):
model = 'Model.Customer'
registry = registry
Add the **registry** during init
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This solution is use during the instanciation
::
customer_schema = CustomerSchema(registry=registry)
Add the **registry** by the context
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This solution is use during the instanciation or after
::
customer_schema = CustomerSchema(context={'registry': registry})
or
::
customer_schema = CustomerSchema()
customer_schema.context['registry'] = registry
Add the **registry** when the de(serialization or validator is called
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
::
customer_schema.dumps(customer, registry=registry)
customer_schema.dump(customer, registry=registry)
customer_schema.loads(dump_data, registry=registry)
customer_schema.load(dump_data, registry=registry)
customer_schema.validate(dump_data, registry=registry)
**model** option
----------------
This option add in the model name. As the registry, this option
can be passed by definition, initialization, context or during the call of the (de)serialization / validation
::
class AnySchema(SchemaWrapper):
model = "Model.Customer"
or
::
any_schema = AnySchema(model="Model.customer")
or
::
any_schema.context['model'] = "Model.Customer"
or
::
any_schema.dumps(instance, model="Model.Customer")
any_schema.dump(instance, model="Model.Customer")
any_schema.loads(dump_data, model="Model.Customer")
any_schema.load(dump_data, model="Model.Customer")
any_schema.validate(dump_data, model="Model.Customer")
**only_primary_key** option
---------------------------
This option add in the only argument the primary keys of the model. As the registry, this option
can be passed by definition, initialization, context or during the call of the (de)serialization / validation
::
class CustomerSchema(SchemaWrapper):
model = "Model.Customer"
only_primary_key = True
or
::
customer_schema = CustomerSchema(only_primary_key=True)
or
::
customer_schema.context['only_primary_key'] = True
or
::
customer_schema.dumps(instance, only_primary_key=True)
customer_schema.dump(instance, only_primary_key=True)
customer_schema.loads(dump_data, only_primary_key=True)
customer_schema.load(dump_data, only_primary_key=True)
customer_schema.validate(dump_data, only_primary_key=True)
**required_fields** option
--------------------------
This option force the generated fields, and only them to be requried.
::
class CustomerSchema(SchemaWrapper):
model = "Model.Customer"
required_fields = True
# or required_fields = [ list of fieldname ]
or
::
customer_schema = CustomerSchema(required_fields=True)
or
::
customer_schema.context['required_fields'] = True
or
::
customer_schema.loads(dump_data, required_fields=True)
customer_schema.load(dump_data, required_fields=True)
customer_schema.validate(dump_data, required_fields=True)
.. note:: All the attributes can take **True** or the list of the fieldname to be required
Use the field JsonCollection
----------------------------
This field allow the schema to inspect an AnyBlok.fields.Json in an any specific instance to
validate the value.
AnyBlok models::
@register(Model)
class Template:
name = anyblok.column.String(primary_key=True)
properties = anyblok.column.Json(defaumt={})
@register(Model)
class SaleOrder:
id = anyblok.column.Integer(primary_key=True)
number = anyblok.column.Integer(nullable=False)
discount = anyblok.column.Integer()
AnyBlok / Marchmallow schema::
class SaleOrderSchema(SchemaWrapper):
model = 'Model.SaleOrder'
class Schema:
discount = JsonCollection(
fieldname='properties',
keys=['allowed_discount'],
cls_or_instance_type=marshmallow.fields.Integer(required=True)
)
Use::
goodcustomer = registry.Template.insert(
name='Good customer',
properties={'allowed_discount': [10, 15, 30]
)
customer = registry.Template.insert(
name='Customer',
properties={'allowed_discount': [0, 5, 10]
)
badcustomer = registry.Template.insert(
name='Bad customer',
properties={'allowed_discount': [0]
)
schema = SaleOrderSchema(registry=registry)
--------------------------
data = schema.load(
{
number='SO0001',
discount=10,
},
instances={'default': goodcustomer}
)
--------------------------
data = schema.load(
{
number='SO0001',
discount=10,
},
instances={'default': customer}
)
==> error = {}
--------------------------
data = schema.load(
{
number='SO0001',
discount=10,
},
instances={'default': badcustomer}
)
==> error = {'discount': ['Not a valid choice']}
