我如何使用 Elasticsearch 从 Django 的前端获取 edit/delete 数据?

How do i edit/delete data from the frontend in Django with Elasticsearch?

我想从我的后端 (postgresql) 检索数据到前端,这样我就可以 edit/delete 它了。

注意:我的项目正在使用django_elasticsearch_dsl_drf

我已经在 views.py 中实现了这个:

def update(request, id):
    resp = Response.objects.get(pk = id)
    resp.response = request.POST.get('Response')
    resp.save()
    return render(request, 'app/update', {
    })

urls.py:

url(r'update/(\d+)/$', views.update, name="update")

如何在我的表单中显示它?

update.html:

<table class="dataTable">

{% for field in qform.visible_fields %}
    <tr>
        <th>{{ field.label_tag }}*</th>
        <td>{{ field }}</td>
    </tr>
{% endfor %}
    <tr>
        <th>{{ rform.Response.label_tag }}*</th>
        <td>{{ rform.Response }}</td>
    </tr>
    <tr>
        <th>{{ rform.Topic.label_tag }}*</th>
        <td>{{ rform.Topic }}</td>
    </tr>
    <tr>
        <th>{{ rform.Client.label_tag }}*</th>
        <td>{{ rform.Client }}</td>
    </tr>
    <tr>
        <th>{{ rform.Planit_location.label_tag }}*</th>
        <td>{{ rform.Planit_location }}</td>
    </tr>
    <tr>
        <th>{{ rform.Date_added.label_tag }}</th>
        <td>{{ rform.Date_added }}</td>
    </tr>
    <tr>
        <th>{{ rform.Document.label_tag }}</th>
        <td>{{ rform.Document }}</td>
    </tr>

此外,当我尝试访问 url .../update

时,我收到断言错误 "No exception message supplied"

编辑 堆栈跟踪:

django_1         |     raise TemplateDoesNotExist(template_name, chain=chain)
django_1         | django.template.exceptions.TemplateDoesNotExist: app/update/

您的 url 路径应该是:

url(r'update/(?P<id>\d+)/$', views.update, name="update")

此外,您需要return更新方法中的内容:

   return render(request, 'update_add.html', { 'rform': resp })
