[django] shell 사용하기

이번에는 장고 셸을 이용해 데이터베이스에 저장된 값을 출력해보거나 데이터를 추가하는 방법에 대해 알아보겠습니다.

1. shell 실행하기

$> python manage.py shell

2. Candidate object 에 저장된 데이터 모두 가져오기

>>> candidates = Candidate.objects.all()

3. 특정 조건을 만족하는 데이터만 가져오기

>>> no1 = Candidate.objects.filter(party_number = 1)

>>> from elections.models import Candidate
>>> Candidate.objects.all()
<QuerySet [<Candidate: James>, <Candidate: Paul>]>
>>> new_candidate = Candidate(name="Lubio")
>>> Candidate.objects.all()
<QuerySet [<Candidate: James>, <Candidate: Paul>]>
>>> new_candidate.save()
>>> Candidate.objects.all()
<QuerySet [<Candidate: James>, <Candidate: Paul>, <Candidate: Lubio>]>
>>> no1 = Candidate.objects.filter(party_number=1)
>>> no1
<QuerySet [<Candidate: James>, <Candidate: Lubio>]>
>>> no1[1]
<Candidate: Lubio>
>>> no1[1].party_number
1
