Templates django管理模型，覆盖的change\u form.html缺少上下文

我有以下3个模型，每一个模型都与它的孩子有一对多的关系

* Experiment
  * Site (lab, schools, etc.)
     * Participants

因为一个站点可能有数百名参与者，所以我覆盖了它的models change\u form.html，在“after\u field\u set”块中添加了一个“bulk create”表单

以下是我的项目/模板/管理员/我的应用程序/网站/更改表单.html：

{% extends "admin/change_form.html" %}
{% load i18n admin_urls %}

{% block after_field_sets %}
{{ block.super }}
<h3>Bulk Create Participants</h3>
 <form method="POST">
    <input type="hidden" name="action" value="create"/>
    <label>First uid (inclusive) <input type="text" name="firstUid"/></label>
    <label>Last uid (inclusive) <input type="text" name="lastUid"/></label>
    <label>Condition Order<input type="text" name="conditionOrder"/></label>
  </form>
<hr/>

{% endblock %}

是否需要向上下文传递更多信息以显示整个表单

任何帮助都将不胜感激。

事实证明，更好的方法是不要覆盖change\u form.html模板，而是为我的站点模型创建一个

ModelForm

，在这里我定义了一些额外的字段（不是实际模型的一部分），在这些字段上设置required=False，将它们添加到ModelAdmin的字段集中，并在my

SiteAdmin:：save_model（）

class SiteAdmin(admin.ModelAdmin):
    fields = ['experiment', 'name', 'description']
    readonly_fields = ['experiment']
    inlines = [ParticipantInline]

        urls = super(SiteAdmin, self).get_urls()
        my_urls = [
            url(r"^(?P<pk>[0-9]+)/$", self.admin_site.admin_view(self.my_view,
