我如何通过 Django 中选中的表单复选框过滤查询集?

how can i filter queryset by checked form checkboxes in django?

我需要根据 django 形状中标记的复选框更新模型 我怎样才能在查询

中只得到一些table字段

应该通过查询集更新“checked”行 models.py

class moIn(models.Model):
    date = models.DateTimeField(auto_now_add=True, verbose_name='')
    dateUpdate = models.DateTimeField(auto_now=True)
    ts = models.IntegerField(verbose_name='')
    pl = models.IntegerField(verbose_name='')
    rem = models.IntegerField(verbose_name='')
    comment = models.TextField(max_length=200, verbose_name='', blank=True)
    staffer = models.ForeignKey(User, on_delete=models.PROTECT, verbose_name='')
    checked = models.BooleanField(verbose_name='', default=False)
    checkedUser = models.ForeignKey(User, on_delete=models.PROTECT, verbose_name='', blank=True, null=True, related_name='checkedUser')

通过单击此复选框,您将需要接收数据库记录 forms.py

class checkForm(ModelForm):
    checked = fields.BooleanField(required=False)
    class Meta:
        model = moIn
        fields = {"id", "checked"}

views.py

def dashboard(request):
    if request.user.groups.filter(name='DashBoardAccess').exists():
        form = checkForm
        f = tableDashFilter(request.GET, queryset=moIn.objects.all())
        if request.method == 'POST':
            form = checkForm(request.POST)
            if form.is_valid():
                tt = form.save(commit=False)
                data = form.cleaned_data
                field = data['checked']=True
                f.qs.filter(checked=field).update(checked=True, checkedUser=request.user)
                return HttpResponse('ok')
        else:
            context = {
                'filter': f,
                'form': form
            }
            return render(request, 'dashboard/index.html', context)
    else:
        raise Http404()

在粗体行中,您只需要获取那些标记了复选框的行

f.qs.filter(checked=field).update(checked=True, checkedUser=request.user)

查询集使用“.values()”即可获取所有字段,与foreignKey一起使用需要显式指定模型字段:

f = tableDashFilter(request.GET, queryset=moIn.objects.values('id','date','ts','pl','rem','comment','checked','staffer__username','checkedUser__username'))

输入的“值”,也将通过以下方式获得: 由于可以有多个值(标记的复选框),因此会有一个“.getlist”

checkID = request.POST.getlist('checked')

查询设置过滤器:

f.qs.filter(id__in=checkID).update(checked=True, checkedUser=request.user)

在html模板中通过循环,遍历并插入模型id

的输入值
