该记录未保存在DJango SQLite数据库中

Question

我正试图在一个与另外两个模型(User和Exercise(相关的模型(Score(的数据库中保存一条记录，我收到的表单正确，使用save((指令没有任何作用。我甚至不会出错。这里的代码：

表单.py

class ScoreForm(forms.ModelForm):
#idUser = forms.IntegerField(widget=forms.HiddenInput(), label='idUser')
idExercise = forms.IntegerField(widget=forms.HiddenInput(), label='idExercise')
value = forms.FloatField(widget=forms.HiddenInput(), label='Value')
class Meta:
model = Score
fields = ['idExercise', 'value']

视图.py

def save_exercise(request):
if request.method == 'POST' and request.is_ajax:
form_score = ScoreForm(request.POST, instance=request.user)
if form_score.is_valid():
form_score.save()
else:
print('Tenemos un error')
return HttpResponse('Respuesta')

JavaScript

document.getElementById('id_value').value = score;
document.getElementById('id_idExercise').value = idexer
// document.getElementById('id_idUser').value = iduser
let data = new FormData($('#scores').get(0));
Swal.fire({
title: '<strong>Tu resultado: </strong>',
icon: 'success',
html:              
`<div class="progress"  style="height: 30px;"><div class="progress-bar progress-bar-striped progress-bar-animated" style="width:${number}%">${number}%</div></div>` +
`Ganaste: ${score.toFixed(2)}`,
focusConfirm: false,
confirmButtonText:
'<i class="fa fa-thumbs-up"></i> Okey!',
preConfirm: () => {
$.ajax({
type: "POST",
url: "/polls/save/",
data: data, 
processData: false,
contentType: false,
success: function(){
console.log('Funciona!')
show_exercise()
}
})
}
})

在html文件中

<div class="row d-flex justify-content-center">
<form method="POST" action="" novalidate id='scores'>
{% csrf_token %}
{{ form|crispy}}
</form>
</div>

表单的所有输入都是类型隐藏的，因为经过几次计算，我分配了它们各自的值，表单是使用AJAX 从模态发送的

我找不到答案，因为我不知道该找什么错误，你能帮我吗

解决方案如下，在文件views.py 中

def save_exercise(request):
scr = Score.objects.filter(idExercise=request.POST['idExercise'], idUser=request.user)
# print(serializers.serialize('json', scr))
exer = Exercise.objects.get(id=request.POST['idExercise'])
if request.method == 'POST' and request.is_ajax():
if scr:
scr.update(value=request.POST['value'])
else:
scr = Score(idUser=request.user, idExercise=exer, value=request.POST['value'])
scr.save()
return HttpResponse('Respuesta')

我没有考虑到与我的分数模型相关的实例。
