无法将数组传递到Django REST

Question

我有一个REST端点。当我通过DRF GUI访问这个端点时，我可以手动输入我的数据，它成功地工作了。我的模型是这样的：

class Post(models.Model):
    title       = models.CharField(max_length=100, null=False)
    content     = HTMLField()
    created_at  = models.DateField(auto_now_add=True)
    authors     = models.ManyToManyField(User)

我的序列化程序和视图如下所示：

class CreatePostSerializer(CreateAPIView):
    serializer_class = PostSerializer

class PostSerializer(serializers.ModelSerializer):

    class Meta:
        model = Post
        fields = ('title', 'content', 'authors')

当我实际尝试通过Ajax将数据提交到端点时，如下所示：

$.ajax({
    type: 'POST',
    url: '/api/save-post/',
    data: {
    "csrfmiddlewaretoken": getCookie('csrftoken'),
    "title": "dasf",
    "desct": "dasf",
    "content": "fdasf",
    "authors": [1,2]
    },
    success: function (msg) {
        console.log(msg);
    }
});

我得到一个错误，说：{"authors":["This list may not be empty."]} with a payload sending：

title: dasf
desct: dasf
content: fdasf
authors[]: 1

我已经尝试将应用程序更改为contentType /json，我几乎尝试了所有的方法，但似乎都不起作用。我如何才能使我的端点理解我发送的内容？

Answer 1

var authors = [];
authors[0] = 1;
authors[1] = 2;

var arr = {
    "csrfmiddlewaretoken": getCookie('csrftoken'),
    "title": "dasf",
    "desct": "dasf",
    "content": "fdasf",
    "authors": authors
    };

$.ajax({
    url: '/api/save-post/',
    type: 'POST',
    data: arr,
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    success: function(msg) {
        alert(msg);
    }
});
