Django REST 通用 ListCreateView GET 请求有效但 POST 请求无效

Question

我创建了一个通用的 ListCreateAPI 视图。我能够对视图执行 GET 请求，但不能执行 POST 请求。

这是我的模型：

class InvoiceEntry(models.Model):

    SERVICE_OR_EXPENSE_CHOICE = [('SER', 'Service'),('EXP', 'Expense')]
    TYPE_CHOICE = [('BPA', 'BPA'),('CAE', 'CAE'),('MEC', 'MEC'),('TRA', 'Travel')]

    invoice_number = models.CharField(max_length=20)
    description = models.CharField(max_length=200)
    rate = models.FloatField()
    units = models.FloatField()
    discount = models.FloatField(default=0)
    amount = models.FloatField()
    service_or_expense = models.CharField(max_length=10, choices=SERVICE_OR_EXPENSE_CHOICE)
    type = models.CharField(max_length=10, choices=TYPE_CHOICE)

    def __str__(self):
        return '[' + str(self.invoice_number) + '][' + self.description + '][' + self.service_or_expense  + '][' + self.type + ']'

这是我的观点：

class InvoiceEntryListCreate(ListCreateAPIView):

    queryset = InvoiceEntry.objects.all()
    serializer_class = InvoiceEntrySerializer

这是我的序列化器：

class InvoiceEntrySerializer(serializers.ModelSerializer):

  class Meta:
    model = InvoiceEntry
    fields = ['invoice_number', 'description', 'rate', 'units', 'discount', 'amount', 'service_or_expense', 'type']

尝试 post 请求时出现以下错误：

{ “详细信息”：“JSON 解析错误 - 预期值：第 1 行第 1 列（字符 0）” }

Answer 1

就像 Abdul 和 Carlos 提到的那样，它需要作为 JSON 有效负载

提交
