Question

我试图按照Django文档中的示例来为我的表单添加一个选择字段。我创建了以下选择模型：

class Ref_AccessDescription(models.Model):
    FACILITY = '7'
    MARKET = '6'
    DIVISION = '5'
    GROUP = '4'
    CORPORATE = '3'
    DEVELOPER = '1'
    access_level_CHOICES = (
        (FACILITY, 'Facility'),
        (MARKET, 'Market'),
        (DIVISION, 'Division'),
        (GROUP, 'Group'),
        (CORPORATE, 'Corporate'),
        (DEVELOPER, 'Developer'),
    )
    access_level = models.CharField(
        max_length=1,
        choices=access_level_CHOICES,
        default=FACILITY,
    )

    def is_corporate(self):
        return self.access_level in (self.CORPORATE)

    def is_developer(self):
        return self.access_level in (self.DEVELOPER)

然后我创建以下表格来拉动所有对象：

class AccessLevelForm(forms.Form):
    accesslevel = forms.ModelChoiceField(Ref_AccessDescription.objects.all())

我创建视图以使用传递我的参数的表单：

form = AccessLevelForm()
errors = form.errors or None # form not submitted or it has errors

args = {'retreivecheckbox': reportlist,'form': form,'errors': errors}

return render(request,'accounts/requestaccess.html', args)

当我尝试在模板中渲染表单时，它不会用我的选择字段填充它。

<label for="accesslevel">Access Level</label>
<select class="form-control" id="accesslevel">
  <option>{{ form.accesslevel }} </option>

我还尝试过使用{{form}}并且没有任何内容被填充
