TypeError : unhashable type : 'bytearray'

Question

저는 장고를 처음 사용하고 홈페이지를 만들려고합니다. 하지만 이미 데이터베이스 설정에 문제가 있습니다. 내가

python manage.py migrate 

를 실행하면이 오류를 내가 파이썬 3.4, 장고-1.7.4을 사용하고

을 얻고 SQL 연결을위한 MySQL의 커넥터 - 파이썬 2.0.2. 이 프로젝트에서는 python 3 venv로 가상 환경을 만들었습니다. 나는이 프로젝트를 github에서 개최합니다 : https://github.com/pkreker/p_kreker

미리 감사드립니다!

Answer 1

오늘이 오류가 발생했습니다. 나는 내 데이터베이스를 utf8_bin 데이터 정렬로 만들었는데, 데이터 정렬의 이유라고 생각합니다. utf8_general_ci으로 다시 만든 DB를 삭제하고 마이그레이션을 실행하여 정상적으로 작동했습니다.

Answer 2

나는이 MySQL의 커넥터 - 파이썬에 버그가 될 가능성이 높습니다 생각 - 그것은 장고 1.7.4를 지원합니까? sqlite를 사용하여 코드를 실행하면 코드가 올바르게 작동합니다.

Answer 3

버그 헤드 라인에서 "Django"를 지정하지 않았으므로 많은 Python 3 초보자가 여기에 올 것으로 예상됩니다. "bytearray"에 대한 해시 가능/불변의 카운터 파트는 "바이트"유형입니다.

>>> b1 = bytearray([1, 2, 3]) 
>>> s = set() 
>>> s.add(b1) 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
TypeError: unhashable type: 'bytearray' 
>>> b2 = bytes(b1) 
>>> b2 
b'\x01\x02\x03' 
>>> s.add(b2) 
>>>
