Question

我有一个模特＆＃39;读者＆＃39;它扩展了默认用户＆＃39;模型：

def loopNplot(NSdf, variantsDF, window):
    #store window
    windows = list(range(1,101))
    #store diversity
    diversity = []

    #Loop through windows appending to the list.
    for i in range(window, 101000, window):

        #Create a list to hold counts for each chromosome (which we then take the mean of)
        tempList = []

        #Loop through chromosomes
        for j in NSdf['CHROM']:
            #Subset NS polymorphisms
            subDF = vtable.loc[(vtable['CHROM'] == j)].copy()
            #Subset all variants
            subVar = all_variants.loc[(all_variants['CHROM'] == j)].copy()

            x = windowAvg(subDF, subVar, i)
            #convert series to list
            x = x.tolist()
            #extend templist to include x
            tempList.extend(x)

        #Append mean of tempList - counts of diversity - to list.
        diversity.append(sum(tempList)/len(tempList))


    #Copy diversity
    divCopy = list(diversity)
    #Add a new first index of 0
    diversity = [0] + diversity
    #Remove last index
    diversity = diversity[:-1]
    #x - diversity to give number of variants in each window
    div = list(map(operator.sub, divCopy, diversity))

    plt.scatter(windows, div)

    plt.show()

问题1 ：我可以直接创建一个Reader而不是User（无需将读者与我现在在管理界面中看到的现有用户相关联），在这种情况下应该如何我的POST电话看起来像？对于目前注册新用户，我需要用户名，密码1，密码2。

问题2 ：在创建阅读器时，我还想为该阅读器创建心愿单。如何实现？

到目前为止，我有一个序列化器：

class Wishlist(models.Model):
    wishlist_id = models.AutoField(primary_key=True)

class Reader(models.Model):
    user = models.OneToOneField(User)
    phone = models.CharField(max_length=30)
    address = models.CharField(max_length=80)
    dob = models.DateField(auto_now=False, auto_now_add=False, null=True, blank=True)
    # A library has many readers
    which_library = models.ForeignKey('Library', related_name='readers', on_delete=models.CASCADE)
    wishlist = models.OneToOneField(Wishlist, null=True, blank=True)

    #This helps to print in admin interface
    def __str__(self):
        return u"%s" % (self.user)

观点：

class ReaderSerializer(serializers.ModelSerializer):
    class Meta:
        model = Reader
        fields = '__all__'
        #depth = 1

    def create(self, validated_data):
        wishlist_data = validated_data.pop('wishlist')
        reader = Reader.objects.create(**validated_data)
        Wishlist.objects.create(reader=reader, **wishlist_data)
        return reader

我认为我的序列化程序会自动创建一个wishlist实例，但它并没有。

Django Rest Framework自定义用户模型创建实例以及嵌套对象实例
