这是一个正常的表单填写代码，我在其中创建了表单并将 request.post 传递给它。发布请求数据已正确捕获，但在传递到表单后未保存。django 3.1 版是基础语言。

===view===
def adst(request):
    lists   = Site.objects.filter(deleted=False)
    country = Country.objects.filter(deleted=False)
    company = Company.objects.filter(deleted=False)
    region  = Region.objects.filter(deleted=False)
    location= Location.objects.filter(deleted=False)
    sbu     = SBU.objects.filter(deleted=False)
    delta   = {'status': True}
    if request.method == 'POST':
        print(request.POST)                                     # Print_Output
        request.POST                = request.POST.copy()
        request.POST['inserted_by'] = request.user.id
        form = SiteForm(request.POST)
        **if form.is_valid():**
            form.save()
    print(request.GET)                                          # Print_Output
    context = {'form' : SiteForm(), 'list' : lists, 
    'data' : delta, 'sbu' : sbu,'country' : country,
    'company' : company, 'region' : region,
    'location' : location}
    return render(request, 'masters/site.html', context)

===Post Data===
<QueryDict: {'csrfmiddlewaretoken': ['sdtbHHn5OVAf19kkaJUlijHzURZEHNNLKm7PLnR6bxrodIKH4rbgB'], 'country': ['India'], 'company': ['GILI'], 'region': ['north'], 'location': ['Vikhroli'], 'sbu': ['goejo nw'], 'site': ['asdasd'], 'status': ['on']}>

===Form===
class SiteForm(ModelForm):
    class Meta:
        model = Site
        fields = ['id','code','site', 'country', 'company', 'region', 'location', 'sbu', 'status','deleted', 'inserted_by', 'updated_by']

===Model===
class Site(models.Model):
    code        = models.CharField(max_length=250, null=True, blank=True, db_column='code')
    site        = models.CharField(max_length=250, null=True, db_column='site')
    country     = models.ForeignKey(Country, null=True, blank=True, on_delete=models.CASCADE)
    company     = models.ForeignKey(Company, null=True, blank=True, on_delete=models.CASCADE)
    region      = models.ForeignKey(Region, null=True, blank=True, on_delete=models.CASCADE)
    location    = models.ForeignKey(Location, null=True, blank=True, on_delete=models.CASCADE)
    sbu         = models.ForeignKey(SBU, null=True, blank=True, on_delete=models.CASCADE)
    status      = models.BooleanField(default=True, db_column='status')
    deleted     = models.BooleanField(default=False, null=True, blank=True, db_column='deleted')
    inserted_by = models.BigIntegerField(null=True, blank=True, db_column='inserted_by')
    inserted_on = models.DateTimeField(auto_now_add=True, db_column='inserted_on')
    updated_by  = models.BigIntegerField(null=True, blank=True, db_column='updated_by')
    updated_on  = models.DateTimeField(auto_now=True, db_column='updated_on')

    def __str__(self):
        return self.site
    
    def datamodify(self):
        return self.inserted_on >= timezone.now() - datetime.timedelta(days=1)
        return self.updated_on >= timezone.now() - datetime.timedelta(days=1)
