Utilities to make it easier to work with Ethereum from your Django app.
Project description
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))
