Django formset - 更改字段类型

Question

我的参数模型如下：

class Parameter(models.Model):
    spot = models.ForeignKey(Spot, related_name = 'spot_parameters', verbose_name = _("Spot"))
    parameter = models.ForeignKey(ParameterTemplate, verbose_name = _("Parameter"))
    value = models.CharField(max_length = 255, db_index = True, verbose_name = _("Value"))
    is_auto_generated = models.BooleanField(default = False, verbose_name = _("Is auto generated"))

和ParameterTemplate模型：

class ParameterTemplate(PositionMixin):
    DATA_TYPE_CHOICE = (
        ('int', "int"),
        ('decimal', "decimal"),
        ('text', "text"),
        ('list', "list"),
        ('size', "size"),
        ('boolean', "boolean"),
    )

    name = models.CharField(max_length = 255, verbose_name = _("Name"))
    data_type = models.CharField(
        max_length=50, 
        choices=DATA_TYPE_CHOICE, 
        db_index=True, 
       verbose_name=_("Data type")
       )
    values = models.CharField(max_length = 255, blank = True, null = True, verbose_name = _("Value list"))
    glyph_class = models.CharField(max_length = 255, blank = True, null = True, verbose_name = _("Icon"))

创建表单时遇到问题。

例如，如果DATA_TYPE_CHOICE是参数的布尔值，我想在表单复选框中显示，而不是TextInput

@EDIT

参数表单视图

@login_required @secure_required def account_spot_parameters_change（request，spot_id）：     spot = get_object_or_404（Spot，id = spot_id，user = request.user）

title = _("Spot parameters")

ParameterFormSet = inlineformset_factory(Spot, Parameter, form = ParameterForm, extra = 0)

if request.method == 'POST':
    formset = ParameterFormSet(request.POST, instance = spot)
    if formset.is_valid():
        formset.save()
        formset = None
        messages.success(request, _("Your changes have been saved."))
    else:
        messages.error(request, _("Form is not filled correctly. Please check the highlighted fields."))
else:
    formset = ParameterFormSet(instance = spot)

extra_context = {
    'spot': spot,
    'title': title,
    'formset': formset,
    'mode': 'parameters',
}

return shortcuts.render(request, 'account_spot_change.html', extra_context)

ParameterForm

class ParameterForm(forms.ModelForm):
class Meta:
    model = Parameter
    fields = ('parameter', 'value')

def __init__(self, *args, **kwargs):
    super(ParameterForm, self).__init__(*args, **kwargs)
    add_widget_css_class(self, 'form-control')

模板

% for form in formset %}
      {% for field in form.hidden_fields %}
        {{ field }}
      {% endfor %}

      <div class="form-group">
        <div class="col-sm-4 col-sm-offset-2">  
          {{ form.parameter }}
        </div>

        <div class="col-sm-3">
          {{ form.value }}
        </div>


        <div class="col-sm-1 text-center">
          {{ form.DELETE }}
        </div>
      </div>

    {% endfor %}
