如何显示 SQLite 数据库中的某些信息？

Question

我想显示从 SQLite 数据库获取的信息，但我只想显示与用户相关的数据。

由于每个用户的电子邮件都是唯一的，我希望它查看是否与当前签名用户的电子邮件匹配。下面是上面对应视图的代码

更新：我刚刚尝试做一个过滤器

claims = SaveClaimForm.objects.filter(email=user.email) 

def newclaim(request):
  
  context = initialize_context(request)
  user = context['user']
  if request.method == 'POST':
      name = request.POST['name_field']
      email = request.POST['email_field']
      claim = request.POST['claim_field']
      claimtype = request.POST.get('claimtype')
      description = request.POST['description_field']
      receipt = request.POST.get('receipt_field')
      cheque = request.POST.get('cheque_field')
      ins = SaveClaimForm(name=name, email=email, claim=claim, claimtype=claimtype, description=description, receipt=receipt, cheque=cheque)
      ins.save()
      print("The Data has been written")
  return render(request, 'Login/newclaim.html/', context)

工作更新视图（参考给出的答案）：

  def viewclaims(request):
      context = initialize_context(request)
      user = context['user']
      if user.get('email', None):
        claims = SaveClaimForm.objects.filter(email=user.get('email', None))
        return render(request, 'Login/existingclaims.html', {'claims':claims, 'user':user})
 

Answer 1

See manual

应该是这样的

if user.get('email', None):
  SaveClaimForm.objects.filter(email=user.get('email', None))
else:
  return HttpResponse('Unauthorized', status=401)

代替

SaveClaimForm.objects.all()
