django를 레거시 데이터베이스에 연결하는 중 오류가 발생했습니다.

Question

브라우저에서 실행되는 django 앱에서 dcm4chee pacs 데이터베이스 (postgresql)의 데이터베이스 필드를 표시하려고합니다. 나는 모델을 만드는 inspectdb를 사용했다 - 아래의 관련 비트 : 내가 장고 관리자에서 응용 프로그램에 추가 할 때, 나는 "초과 최대 재귀 깊이"를 얻을 그러나

class Study(models.Model): 


    pk = models.IntegerField(primary_key=True) 
    patient_fk = models.ForeignKey(Patient, null=True, db_column='patient_fk', blank=True) 
    description = models.CharField(max_length=400, blank=True) 

    class Meta: 
     db_table = 'study' 

    def __unicode__(self): 
     return u"%s" % self.pk

Answer 1

pk은 특별한 경우로 취급됩니다. 당신은 당신의 분야를 pk으로 지칭하지 말아야합니다. 시도 :

id = models.IntegerField(primary_key=True, db_column="pk") 

문제는 pk 속성에 대한 세터로 사용되는 _set_pk_val,, 그냥 기본 키, _meta.pk.attname에 대한 속성 이름이 'PK'
