Django - 从表单小部件中删除添加新记录>

我创建了一个表单窗口小部件,它自动在窗体顶部添加一个添加新记录部分,我不想在那里.谁能告诉我如何禁用它？我只想显示变量而不是添加表单.

forms.py

class TemplateVariablesWidget(forms.Widget):
    template_name = 'sites/config_variables.html'

    def render(self, name, value, attrs=None):
        sc_vars = ConfigVariables.objects.filter(type='Showroom')
        wc_vars = ConfigVariables.objects.filter(type='Major Site')
        context = {
            'SConfigVariables' : sc_vars,
            'WConfigVariables' : wc_vars,
        }
        return mark_safe(render_to_string(self.template_name, context))


class VariableForm(forms.ModelForm):
    variables = forms.CharField(widget=TemplateVariablesWidget, required=False)

    class Meta:
        model = ConfigVariables
        fields = "__all__" 

admin.py

class ConfigTemplateAdmin(admin.ModelAdmin):  
    list_display = ('device_name', 'date_modified')
    def change_view(self, request, object_id, form_url='', extra_context=None):
        extra_context = extra_context or {}
        #extra_context['include_template'] = '/path/to/template.html'
        extra_context['include_form'] = VariableForm
        return super(ConfigTemplateAdmin, self).change_view(
            request, object_id, form_url, extra_context=extra_context,
        )

change_view.html

{% block extra_content %}
    {% if include_template %}
        {% include include_template %}
    {% endif %}
    {% if include_form %}
    

        {% csrf_token %}
        {{ include_form.as_p }}
    
    {% endif %}
{% endblock %}
