在django如何显示父模型数据与子模型数据在更改列表视图？ [英] In django How to display parent model data with child model data in change list view?

问题描述

示例：我有一个发票作为父模型和发票明细作为子模型。我想在发票模型管理员中显示子信息作为发票的条目。目标是在列表页面中实现统一视图。有什么办法可以实现的：它应该是这样的：

Example: I have an Invoice as the parent model and invoice details as the child model. I would like to display the child details in the Invoice model admin as entries of the invoice. Target is to achieve a consolidated view in the listing page itself. Is there any alternative to achieve this: It should look like this:

Invoice 1:
 -details 1
 -details 2
Invoice 2:
 -details 1
 -details 2
 -details 3

在django 1.6.5中有没有可用的模板？

Is there some template available as this in django 1.6.5?

推荐答案

假设以下示例：

models.py

class Invoice(models.model):
    date = models.DateTimeField()  # for example

class InvoiceDetail(models.model):
    invoice = models.ForeignKey(Invoice)

views.py

# example, don't fetch all in production
return render(request, 'mytemplate.html', {'invoices': Invoice.objects.all()})

然后你的模板将是：

mytemplate.html

{% for invoice in invoices %}
    <p>Invoice {{ invoice.id }} ({{ invoice.date }})
    {% if invoice.invoicedetail_set %}
        <ul>
        {% for detail in invoice.invoicedetail_set %}
            <li>Detail {{ detail.id }}</li>
        {% endfor %}
        </ul>
    {% endif %}
    </p>
{% endfor %}

对于管理界面，有一个非常好的教程 Django文档：教程：添加相关对象。

For the admin interface, there is a very good tutorial in Django documentation: Tutorial: Adding related objects.
