데이터베이스 테이블에 해당 테이블이 없습니다. django

Question

장고 프로젝트 'cc'에 새로운 앱 'api'를 만들었습니다.

나는 리모각 데이터베이스 'launchg'을 가지고있다.이 데이터베이스는 레거시를 사용하여 장고와 통합했으며 python manage.py inspectdb > models.py을 사용하여 models.py 파일을 생성했다.

다음으로 생성 된 models.py 파일을 api 앱의 models.py 파일로 대체했습니다. 나는이 데이터베이스 예를 들어 database error:no such table 에 쿼리를 해고하려고 할 때마다

# This is an auto-generated Django model module. 
    # You'll have to do the following manually to clean this up: 
    #  * Rearrange models' order 
    #  * Make sure each model has one field with primary_key=True 
    # Feel free to rename the models, but don't rename db_table values or field names. 
    # 
    # Also note: You'll have to insert the output of 'django-admin.py sqlcustom [appname]' 
    # into your database.

또한, 내 models.py 파일 여기 database error: no such table : web_query

을 알리는 오류입니다 발생했을 때 manage.py sql api 명령을 입력하면 모든 테이블이 표시됩니다. 그것은 무엇입니까 ???

친절히 도움 !!!

Answer 1

가장 큰 차이점은 manage.py sql myapphere을 실행하면 데이터베이스 스키마를 만드는 데 사용한 쿼리가 표시되고 myapp.objects.all()의 출력은 해당 데이터베이스의 항목 목록을 반환하기 만하면됩니다. 예를 들어

, 당신은 문서의 목록을 한 경우 manage.py SQL 명령은 MyApp를에게 특성을 보여줄 것 동안 myapp.objects.all() 데이터베이스에 MyApp를의 인스턴스를 표시합니다.

문제점을 더 보완하려면 DB 클라이언트를 열고 열 이름이 모델에 설명 된 것과 일치하는지 확인하십시오. 일치하지 않는 경우 테이블을 삭제하고 데이터베이스를 다시 동기화해야 할 수도 있습니다.
