.to_message() fails on Arrays #16
Description
Test code:
import os
from eip712_structs import Bytes, Array, EIP712Struct, make_domain
class TestStruct(EIP712Struct):
byte_array = Array(Bytes(32), 4)
byte_array = [os.urandom(32) for _ in range(4)]
domain = make_domain(name='hello')
s = TestStruct(byte_array=byte_array)
print(s.to_message(domain))This code will raise:
Traceback (most recent call last):
File "test.py", line 11, in <module>
print(s.to_message(domain))
File "site-packages/eip712_structs/struct.py", line 165, in to_message
structs = {domain, self}
File "site-packages/eip712_structs/struct.py", line 315, in __hash__
value_hashes = [hash(k) ^ hash(v) for k, v in self.values.items()]

value_hashes = [hash(k) ^ hash(v) for k, v in self.values.items()]

Same problem here. How about changing to
structs = [domain, self]in that line?

I have the same error when I used
.to_message()on Arraysand when I use
.signable_bytes(domain)I get:AttributeError: 'bytes' object has no attribute 'version'PierreMkt commentedon Jul 14, 2022
Same error. Any workaround found ?

This project appears to be dormant. I used a custom solution instead: https://github.com/jvinet/eip712
Perhaps it can work for you, too.

This is fixed in my branch at https://github.com/ViciNFT/py-eip712-structs. The answer posted by @numpde is part of the solution, and there were a few other changes required.

Arrayshould pass variables of type tuple.Like this:byte_array = tuple([os.urandom(32) for _ in range(4)])BoboTiG commentedon Oct 18, 2024
FTR it's fixed on my fork (available on PyPI): https://github.com/BoboTiG/py-eip712-structs-ng
