Question

django rest框架中的嵌套关系存在一些问题

我的 models.py

function populateForm() {
    var form = FormApp.openById('Id of your form');    
    form.setDestination(FormApp.DestinationType.SPREADSHEET, spreadsheet.getId());
    var item = form.addCheckboxItem();

    form.addMultipleChoiceItem()
        .setTitle('What is your phone model?')
        .setChoiceValues([('iPhone 6', 'iPhone 5', ...])

    form.addMultipleChoiceItem()
       .setTitle('What is your phone capacity?')
       .setChoiceValues([('32GB', '64GB', ...])

  ...   
}

serializers.py

 class Category(models.Model):
    category = models.CharField(max_length=128)
    profile = models.ForeignKey(Profile, on_delete=models.CASCADE)

    def __str__(self):
        return self.category


class Interest(models.Model):
    name= models.CharField(max_length=250, default='')
    category = models.ForeignKey(Category, on_delete=models.CASCADE)
    profile = models.ForeignKey(Profile, related_name='category_profiles', on_delete=models.CASCADE)

    def __str__(self):
        return self.name

当我在类别集中获取个人资料时，视图中的

为空

Form Service References for Apps Script

但是如果我在浏览器中单独显示它，则会显示正确的内容

现在，这就是我所拥有的。如何在个人资料中设置适当的类别？预先谢谢你！

Answer 1

您尚未指定概要文件序列化程序应序列化的字段列表。它是空的。

在您的ProfileSerializer中执行此操作

class ProfileSerializer(serializers.ModelSerializer):
    category_set = CategorySerializer(many=True)

    class Meta:
      model = Profile
      fields = ( 'category_set', )

DRF将空东西带入对象
