Fakers for SQLAlchemy

SQLAlchemy Faker is a provider for the Faker library that helps populate SQLAlchemy ORM models with dummy data. Creating a new instance of a model can be as simple as calling fake.sqlalchemy_model(SomeModel).

Installation

The recommend way to install SQLAlchemy Faker is with pip:

pip install faker_sqlalchemy

Example

Say you have some model declared using SQLAlchemy's ORM.

>>> class SomeModel(Base):
...     __tablename__ = "some_model"
...
...     id = Column(Integer, primary_key=True)
...
...     value = Column(String)

And, you want to easily generate some data,

>>> from faker_sqlalchemy import SqlAlchemyProvider
>>>
>>> fake = Faker()
>>> fake.add_provider(SqlAlchemyProvider)
>>>
>>> instance = fake.sqlalchemy_model(SomeModel)

Use instance as desired.

>>> print(instance.value)

Supported Versions

Currently SQLAlchemy versions 1.3 and 1.4 are supported. Support for SQLAlchemy 2.0 will be added when it is released.

Faker versions >=8 are currently supported, though it should be noted that the testing matrix isn't exhaustive. If bugs come up with a particular version of faker beyond version 8.0, submit a ticket to add support.

Python versions >=3.7 are currently supported. If python 3.6 support is desired, submit a ticket to add support. Support for Python 3.11 will be added when it is officially supported by SQLAlchemy. Currently, this is waiting on greenlet releasing support for python 3.11.
