Django Ethereum Utilities

A collection of helpers to make it easier to work with Ethereum from your Django app.

Currently this only consists of a custom model field which stores Ethereum addresses in the checksummed format.

Install

pip install django-ethereum

Fields

EthereumAddressField

A CharField which automatically converts an Ethereum address into its checksummed representation.

    from django_ethereum.fields import EthereumAddressField

    class MyModel(models.Model):
        address = EthereumAddressField()

    my_model = MyModel(address="0x627306090abab3a6e1400e9345bc60c78a8bef57")
    my_model.save()
    print(my_model.address)
    "0x627306090abaB3A6e1400e9345bC60c78a8BEf57"  # Note capitalisation

If the address is invalid a ValidationError will be raised.

Note that the address is stored in the checksummed format. If you want to compare against a non-checksummed address you will need to perform a case-insensitive match (or preferably convert the address to a checksummed address before comparing):

    MyModel.objects.filter(address__iexact=non_checksummed_address)
    # Or
    MyModel.objects.filter(address__iexact=Web3.toChecksumAddress(non_checksummed_address))
