django 모델은 fixture와 일치하지 않습니다

Question

django에서 조명기를 사용하여 초기 값으로 postgresql 데이터베이스를 채우려고합니다. 내가 왜이 오류를 얻고있다

class Article(models.Model): 
    _id = models.CharField(max_length=1000) 
    author_name = models.CharField(max_length=1000) 
    caption = models.CharField(max_length=1000) 
    isGraphic = models.BooleanField(max_length=1000, default=True) 
    pictures = models.URLField(max_length=1000) 
    text = models.CharField(max_length=10000) 
    title = models.CharField(max_length=1000) 
    user_img = models.URLField(max_length=1000) 
    videoname = models.CharField(max_length=1000) 
    vimeo_id = models.IntegerField(max_length=1000)

Answer 1

귀하의 JSON기구에 기본 키가 없습니다. 귀하의 모델에 장고 automatically adds a primary key; id이라고합니다. 이 키가 필요하므로 키를 제공해야합니다.

이 키가없는 것입니다 게시 한 치구, 당신은 그것을 추가해야합니다 : 당신은 당신의 고정에서 모델에 필요한 키 필드를 누락

      "id": "1",

. user_img을 추가해야하고 pictures은 비워 둘 수 없습니다.

조명기는 모델의 모든 유효성 검사 규칙을 통과해야합니다. 모델마다 모든 필드가 필요하기 때문에 모든 필드를 조명기에서 사용할 수 있어야합니다.

또한 정수, 부울 및 url 필드에 대해서는 max_length 인수가 있으며 적용 할 수 없습니다.
