当我运行api时,我没有获得category
名称和subcategory
名称,而是获得了他们的身份,
[
{
"id": 1,
"name": "StrawBerry",
"category": 1,
"subcategory": 1
}
]
我其实想要这样的事情:
[
{
"id": 1,
"name": "StrawBerry",
"category": "Fruits",
"subcategory": "Berries"
}
]
注意:我已经有了类别和子类别。我只是想知道如何访问它们。
models.py
from django.db import models
class Category(models.Model):
category = models.CharField(max_length=200)
parent = models.ForeignKey('self', blank=True, null=True, related_name='children')
class Meta:
unique_together = ('parent' , 'category')
def __str__(self):
return self.category
class SubCategory(models.Model):
subcategory = models.CharField(max_length=200)
category = models.ForeignKey('Category', null=True, blank=True)
parent = models.ForeignKey('self', blank=True, null=True, related_name='subchilren')
class Meta:
unique_together = ('parent' , 'subcategory')
def __str__(self):
return self.subcategory
class Product(models.Model):
name = models.CharField(max_length=200)
category = models.ForeignKey('Category', null=True, blank=True)
subcategory = models.ForeignKey('SubCategory', null=True, blank=True)
def __str__(self):
return self.name
serializers.py
class GetProductSerializer(serializers.ModelSerializer):
class Meta:
model = Product
fields = ('id', 'name', 'category', 'subcategory')
views.py
class GetProductViewSet(viewsets.ModelViewSet):
serializer_class = GetProductSerializer
queryset = Product.objects.all()
答案 0 :(得分:1)
一种解决方案是将category
的{{1}}和subcategory
字段定义为GetProductSerializer
:
StringRelatedField可用于使用 unicode 方法表示关系的目标。

或者,类似地,StringRelatedFields
:
SlugRelatedField可用于使用目标上的字段来表示关系的目标。
