Question

我在这里有一些关于添加到我的模型中的关系字段(herd/herd_id)的问题。它不会作为Animal模型和AnimalSerializer djangorestframework

的字段显示在API中

这是我的动物模型和序列化器：

models.py

class Animal(models.Model):

    this_id = models.CharField(max_length=25)
    name = models.CharField(max_length=25)
    species_type = models.CharField(max_length=25)
    breed = models.CharField(max_length=25)
    date_of_birth = models.DateField()
    birth_weight = models.IntegerField()
    sex = models.CharField(max_length=7)
    sibling_order = models.IntegerField()
    sire_id = models.CharField(max_length=20)
    sire_name = models.CharField(max_length=25)
    dam_id = models.CharField(max_length=25)
    dam_name = models.CharField(max_length=25)
    rf_id = models.CharField(max_length=25)
    comment = models.TextField(max_length=250, null=True)

    herd = models.ForeignKey(Herd, related_name='animals', on_delete=models.CASCADE)

    created_at = models.DateTimeField(auto_now_add=True, editable=False)
    updated_at = models.DateTimeField(auto_now=True, editable=False)

    class Meta:
        ordering = ('name',)

serializers.py

class AnimalSerializer(serializers.ModelSerializer):

    class Meta:
        model = Animal
        fields = (
            'this_id',
            'name', 
            'species_type', 
            'breed', 
            'date_of_birth', 
            'birth_weight', 
            'sibling_order', 
            'sex',
            'sire_id', 
            'sire_name', 
            'dam_id', 
            'dam_name', 
            'rf_id', 
            'comment', 
            'herd_id', // <--- this field wont appear in the djangorestframework UI.
            'created_at', 
            'updated_at',
        )
        read_only_fields = ('id', 'created_at', 'updated_at')

这是图片。并查找它不会出现的herd_id字段。请帮助

Answer 1

我只需将herd_id更改为herd列名称，以便django识别匹配的序列化名称。

添加的新关系字段不会出现在DjangoRestFramework API上
