내 코드는 다음과 같습니다

스택 추적 쇼의 마지막 줄에

def by_name(cls, name): 
    u = Articles.all().filter("name =", name).get() 
    return u 

Answer 1

는 먼저 다음 UTF-8로 인코딩 유니 코드로 값을 변환하려고. 그러나 (암시 적) 변환은 ascii를 사용하는데, 이는 문자열에 충분하지 않습니다. filter에 전달하기 전에 올바른 인코딩을 사용하여 유니 코드로 변환 해 볼 수 있습니다. 예 :

u = Articles.all().filter("name =", name.decode('utf-8')).get() 

(당신이 올바른 인코딩을 제공해야 기억, name은 UTF-8 문자열이 아닌,하지만 Cp1252를, ISO 라틴어 또는 뭔가 다른, 당신은에 지정해야하는 경우 decode 전화)
