因此，我遵循这个教程https://youtu.be/hISSGMafzvU，用我的不同方法(而不是一个要做的应用程序，我试图使它成为一个诊所管理系统)。

所以我面临的问题是我的api正在接收数据，而且没有错误，而且我从本地服务器获得了200个状态代码，这意味着一切正常，但是由于某种原因，数据没有被存储在DB中。

这是代码：

models.py

class Employee(models.Model):
    fullname                   = models.CharField(max_length = 250)
    age                        = models.DateField(null=True, blank=True)
    gender                     = models.CharField(max_length=10, 
    choices=(('Male', 'Male'), ('Female', 'Female')), default='Male')
    usertype                   = models.CharField(max_length = 50, choices=
    (('Admin','Admin'),('Doctor','Doctor'),('Receptionist','Receptionist')),
    default='Receptionist')
    
    def __str__(self):
        return self.fullname

class Patient(models.Model):
    fullname                   = models.CharField(max_length = 250)

    def __str__(self):
        return self.fullname

class Appointments(models.Model):
    Paitent_Attending                = models.ForeignKey(Patient, on_delete= models.CASCADE)
    Doctor_Attending                 = models.ForeignKey(Employee, on_delete= models.CASCADE)
    appointment_date                 = models.DateField()

    def __str__(self):
        return self.Paitent_Attending.fullname

serializers.py

from rest_framework import serializers
from .models import Employee,Patient,Appointments



class PatientSerializers(serializers.ModelSerializer):
    class Meta:
        model = Patient
        fields = '__all__'

class EmployeeSerializers(serializers.ModelSerializer):
    class Meta:
        model = Employee
        fields = '__all__'

class AppointmentsSerializers(serializers.ModelSerializer):
    class Meta:
        model = Appointments
        fields = '__all__'

    employee = Employee.objects.get(id=pk)
    employee.delete()

@api_view(['DELETE'])
def deleteAppointment(request,pk):
    appointment = Appointments.objects.get(id=pk)
    appointment.delete()

    return Response("Appointment was successfully deleted")

通过fetch api发送数据的JS。

function getCookie(name) {
    let cookieValue = null;
    if (document.cookie && document.cookie !== '') {
        const cookies = document.cookie.split(';');
        for (let i = 0; i < cookies.length; i++) {
            const cookie = cookies[i].trim();
            // Does this cookie string begin with the name we want?
            if (cookie.substring(0, name.length + 1) === (name + '=')) {
                cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                break;
            }
        }
    }
    return cookieValue;
}
const csrftoken = getCookie('csrftoken');

var form = document.getElementById('newPatient');
form.addEventListener('submit', function(e) {
    e.preventDefault()
    console.log('form submited');
    var url = 'http://127.0.0.1:8000/api/add-patient/'
    var Fullname = document.getElementById('Fullname').value
    fetch(url, {
        method: 'POST',
        headers:{
            'Content-Type': 'application/json',
            'X-CSRFToken' : csrftoken,
        },
        body: JSON.stringify({'Fullname':Fullname})
    }

    )
})

我仍然是api世界的新手，我在这里很困惑，救命！

这是那些愚蠢的错误之一，当你不把注意力放在名字上的时候。

addPatient属性fullname的名称，fetch api试图将数据发送到不存在的Fullname大写字母F，这导致数据由于在views.py中的代码而不被保存。

def addPatient(request):
   serializer = PatientSerializers(data=request.data)

   if serializer.is_valid():
       serializer.save()

   return Response(serializer.data)

序列化程序正在接收数据，但由于大写F不匹配addPatient属性，即全名而不是全名，这导致序列化程序无效，从而不满足if语句条件，从而无法保存数据xD，请叹
