使用 python 和 django：我的状态没有正确呈现在我的视图上

如何解决使用 python 和 django：我的状态没有正确呈现在我的视图上

所以我的目标是将工作申请的状态显示为默认为“已申请”的下拉列表，但其余的选择将是：('A','已申请'),('B','进行中'),('C','面试安排'),('D','面试完成'),('E','工作机会'),('F','不完整'),('G','未选择'),('H','未知'),但它没有正确渲染，有什么帮助吗？

更新：当我点击“更新状态”时出现错误。 对于“状态”，Job App 表单不应有选择状态的选项，而是自动生成并分配默认值“已申请”，状态的“日期”属性与“日期”相同放入 Job_app

这是我的模型

class Job_application(models.Model):
    name = models.CharField(max_length=100)
    company = models.CharField(max_length=100)
    location = models.CharField(max_length=250)
    date = models.DateField('Date Applied')
    url = models.CharField(
        max_length=250,blank=True
        )
    requirements = models.TextField(
        max_length=500,blank=True
        )
    notes = models.TextField(
        max_length=500,blank=True
        )
    user = models.ForeignKey(User,on_delete=models.CASCADE)

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return reverse('detail',kwargs={'job_id': self.id}) #every model instance has its own method 
        #django will now render the detail page,class Attachment(models.Model): # will implement later with AWS if possible -CO
    url = models.CharField(max_length=250)
    job_app = models.ForeignKey(Job_application,on_delete=models.CASCADE)

    def __str__(self):
        return f'Attachment for job_id: {self.job_id} @{self.url}'

class Status(models.Model):
  date = models.DateField('Date')

  STATUS = (
        ('A','Applied'),'In Progress'),'Interview scheduled'),'Interview complete'),'Job Offer'),'Incomplete'),'Not Selected'),'Unknown'),)
 
  status = models.CharField(
    max_length=1,choices=STATUS,default=STATUS[0][0]
  )

  job_app = models.ForeignKey(Job_application,on_delete=models.CASCADE)

  def __str__(self):
    # Nice method for obtaining the friendly value of a Field.choice
    return f"{self.get_status_display()}"

  # change the default sort
  class Meta:
    ordering = ['-date']

这是我的看法

def home(request):
    return render(request,'home.html')

def about(request):
    return render(request,'about.html')

def jobs_index(request):
    # insert jobs model here
    jobs = Job_application.objects.filter(user=request.user).order_by('-date')
    return render(request,'jobs/index.html',{'jobs': jobs})

def jobs_detail(request,job_id):
    # insert jobs model here
    job = Job_application.objects.get(id=job_id)
    status_form = StatusForm()
    status = Status.objects.filter(job_app=job_id).first()

    return render(request,'jobs/detail.html',{
        'job': job,'status': status,'status_form': status_form,})

def signup(request):
    error_message = ''
    if request.method == 'POST':
        form = UserCreationForm(request.POST)
        if form.is_valid():
            user = form.save()
            login(request,user)
            return redirect('index')
        else:
            error_message = 'Invalid signup data - please try again'
    
    form = UserCreationForm()
    return render(request,'registration/signup.html',{'form': form,'error_message': error_message })

class JobCreate(LoginRequiredMixin,CreateView):
    model = Job_application
    fields = ['name','company','location','date','url','requirements','notes']

    def form_valid(self,form):
        form.instance.user = self.request.user
        return super().form_valid(form)

class JobUpdate(LoginRequiredMixin,UpdateView):
    model = Job_application
    fields = ['name','notes']

class JobDelete(LoginRequiredMixin,DeleteView):
    model = Job_application
    success_url = '/jobs/'

def add_status(request,job_id):
    form = StatusForm(request.POST)
    if form.is_valid():
        new_status = form.save(commit=False)
        new_status.job_id = job_id
        new_status.save()
    
    return redirect('detail',job_id=job_id)

这是我的表格

from .models import Status

class StatusForm(ModelForm):
    class Meta:
        model = Status
        fields = ['date','status']

这是我的detail.html
