---------
Changelog
---------
Version 0.12.4
--------------
* Make it compatible with Python 3.10.
Version 0.12.3
--------------
* Fix HashMapsModel's hardcode field type.
Version 0.12.2
--------------
* Fix access to HashMapsModel's field type when it is hardcoded in a class.
Version 0.12.1
--------------
* Fix `~dirty_models.fields.MultiFieldType` on creation mode.
* Fix `~dirty_models.utils.BaseModelFormatterIter` to be aware about override access modes.
* Exposed all useful classes on package root.
Version 0.12.0
--------------
* Added `access_mode` property to fields.
It could be `~dirty_models.base.AccessMode.READ_AND_WRITE` in order to allow to read and write.
`~dirty_models.base.AccessMode.WRITABLE_ONLY_ON_CREATION` in order to set value only on creation.
`~dirty_models.base.AccessMode.READ_ONLY` in order to prevent writing.
And `~dirty_models.base.AccessMode.HIDDEN` in order to hide field.
* Old field property `read_only` is deprecated in favor of `access_mode` but it can be used like until this version.
* Helper `~dirty_models.base.Creating` to mark model as in creation mode.
* Added class method `~dirty_models.models.BaseModel.create_new_model` build a model and insert data
in creation mode.
* Allowed to override field access model on inherited fields using
`~dirty_models.models.BaseModel.__override_field_access_modes__` hashmap.
Version 0.11.3
--------------
- Fix bug casting string negative float.
- Fix exception casting non valid values to enumerations.
- Added `title` property to fields.
- Added `metadata` property to fields. It could be used to store anything.
- Improved model formatter.
Version 0.11.2
--------------
- Fix bug #107.
- Added `~dirty_models.utils.ModelIterator` class in order to be able to iterate over model fields.
.. code-block:: python
from dirty_models.utils import ModelIterator
for fieldname, field_obj, value in ModelIterator(my_model):
print('Field name: {}'.format(fieldname))
print('Field alias: {}'.format(field_obj.alias))
print('Field value: {}'.format(value))
- Some fixes about read only data.
Version 0.11.1
--------------
- Distribution fixes.
Version 0.11.0
--------------
- New field type `~dirty_models.fields.BytesField`.
- String to integer casting could use any format allowed by Python: HEX (`0x23`), OCT (`0o43`) or
no-meaning underscores (`1_232_232`, only since Python 3.6).
Version 0.10.1
--------------
- `Factory<dirty_models.utils>` feature. It allows to define a factory as
default value in order to be executed each time model is instanced. (Issue #100)
.. code-block:: python
from dirty_models.utils import factory
from datetime import datetime
class Model(BaseModel):
field_1 = DateTimeField(default=factory(datetime.now))
model = Model()
print(model.field_1)
# 2017-11-02 21:52:46.339040
- Makefile fixes.
- Python 3.6 is supported officially. It works since first day, but now tests run on Travis for Python 3.6.
Version 0.10.0
--------------
- Pickable lists.
- Improved pickle performance.
- Setting ``None`` to a field remove content.
- More tests.
- Some code improvements.
Version 0.9.2
-------------
- Fix timezone when convert timestamp to datetime.
Version 0.9.1
-------------
- Fix installation.
Version 0.9.0
-------------
- New EnumField.
- Fixes on setup.py.
- Fixes on requirements.
- Fixes on formatter iters.
- Fixes on code.
- Added ``__version__`` to main package file.
- Synchronized version between main packege file, ``setup.py`` and docs.
- Export only modifications.
Version 0.8.1
-------------
- Added __contains__ function to models and lists. It allows to use ``in`` operator.
- Added ``default_timezone`` parameter to DateTimeFields and TimeFields. If value entered has no a timezone
defined, default one will be set.
- Added ``force_timezone`` parameter to DateTimeFields in order to convert values to a specific timezone.
- More cleanups.
Version 0.8.0
-------------
- Renamed internal fields. Now they use double score format ``__fieldname__``.
- Raise a RunTimeError exception if two fields use same alias in a model.
- Fixed default docstrings.
- Cleanup default data. Only real name fields are allowed to use as key.
- Added `~dirty_models.models.BaseModel.get_attrs_by_path` in order to get all values using path.
- Added `~dirty_models.models.BaseModel.get_1st_attr_by_path` in order to get first value using path.
- Added option to access fields like in a dictionary, but using wildcards. Only for getters.
See: `~dirty_models.models.BaseModel.get_1st_attr_by_path`.
- Added some documentation.
Version 0.7.2
-------------
- Fixed inherited structure
- Added ``get_default_data`` method to models in order to retrieve default data.
Version 0.7.1
-------------
- Solved problem formatting dynamic models
- Added date, time and timedelta fields to dynamic models.
Version 0.7.0
-------------
- Timedelta field
- Generic formatters
- Json encoder
.. code-block:: python
import json
from datetime import datetime
from dirty_models import BaseModel, DatetimeField
from dirty_models.utils import JSONEncoder
class ExampleModel(BaseModel):
field_datetime = DatetimeField(parse_format="%Y-%m-%dT%H:%M:%S")
model = ExampleModel(field_datetime=datetime.now())
assert json.dumps(model, cls=JSONEncoder) == '{"field_datetime": "2016-05-30T22:22:22"}'
- Auto camelCase fields metaclass
Version 0.6.3
-------------
- Documentation fixed.
- Allow import main members from root package.
Version 0.6.2
-------------
- Improved datetime fields parser and formatter definitions. Now there are three ways to define them:
* Format string to use both parse and formatter:
.. code-block:: python
class ExampleModel(BaseModel):
datetime_field = DateTimeField(parse_format='%Y-%m-%dT%H:%M:%SZ')
* Define a format string or function for parse and format datetime:
.. code-block:: python
class ExampleModel(BaseModel):
datetime_field = DateTimeField(parse_format={'parser': callable_func,
'formatter': '%Y-%m-%dT%H:%M:%SZ'})
* Use predefined format:
.. code-block:: python
DateTimeField.date_parsers = {
'iso8061': {
'formatter': '%Y-%m-%dT%H:%M:%SZ',
'parser': iso8601.parse_date
}
}
class ExampleModel(BaseModel):
datetime_field = DateTimeField(parse_format='iso8061')
Version 0.6.1
-------------
- Improved model field autoreference.
.. code-block:: python
class ExampleModel(BaseModel):
model_field = ModelField() # Field with a ExampleModel
array_of_model = ArrayField(field_type=ModelField()) # Array of ExampleModels
Version 0.6.0
-------------
- Added default value for fields.
.. code-block:: python
class ExampleModel(BaseModel):
integer_field = IntegerField(default=1)
model = ExampleModel()
assert model.integer_field is 1
- Added default values at model level. Inherit default values could be override on new model classes.
.. code-block:: python
class InheritExampleModel(ExampleModel):
__default_data__ = {'integer_field': 2}
model = InheritExampleModel()
assert model.integer_field is 2
- Added multi type fields.
.. code-block:: python
class ExampleModel(BaseModel):
multi_field = MultiTypeField(field_types=[IntegerField(), StringField()])
model = ExampleModel()
model.multi_field = 2
assert model.multi_field is 2
model.multi_field = 'foo'
assert model.multi_field is 'foo'
Version 0.5.2
-------------
- Fixed model structure.
- Makefile helpers.
Version 0.5.1
-------------
- Added a easy way to get model structure. It will be used by autodoc libraries as sphinx or json-schema.
Version 0.5.0
-------------
- Added autolist parameter to ArrayField. It allows to assign a single item to a list field,
so it will be converted to a list with this value.
.. code-block:: python
class ExampleModel(BaseModel):
array_field = ArrayField(field_type=StringField(), autolist=True)
model = ExampleModel()
model.array_field = 'foo'
assert model.array_field[0] is 'foo'
------------
Installation
------------
.. code-block:: bash
$ pip install dirty-models
------
Issues
------
- Getter and setter feature needs refactor to be able to use as decorators.
- DynamicModel is too strange. I don't trust in it. Try to use HashMapModel or FastDynamicModel.
-----------
Basic usage
-----------
.. code-block:: python
from dirty_models.models import BaseModel
from dirty_models.fields import StringField, IntegerField
class FooBarModel(BaseModel):
foo = IntegerField()
bar = StringField(name="real_bar")
alias_field = IntegerField(alias=['alias1', 'alias2'])
fb = FooBarModel()
fb.foo = 2
assert fb.foo is 2
fb.bar = 'wow'
assert fb.bar is 'wow'
assert fb.real_bar is 'wow'
fb.alias_field = 3
assert fb.alias_field is 3
assert fb.alias1 is fb.alias_field
assert fb.alias2 is fb.alias_field
assert fb['alias_field'] is 3
