Question

我正在使用django_tables2来显示“修复细节”列表。到现在为止还挺好。但是我想添加一个新字段（它不在模型中）：服务报告列表。关系是1对多。并显示另一个型号中的序列号。这是非常困难，因为我添加了字段但render_NEW_FIELD不起作用，我无法访问服务报告列表，因为在表模型中我只能访问记录而不是repair_detail模型。我正在使用django_tables 0.15

        fields = ('id', 'repair_detail_number', 'article_code', 'registered_date', 'registered_initials', 'customer_reference', 'serials')
        attrs = {'class': 'table table-striped table-bordered protonic'}
        empty_text = "No records found."

如果你想要（1：N而不是N：1）连接表格单元格中的所有相关模型，请尝试通过设置属性在模型层中执行此操作，如下所示：

class RepairDetail(models.Model):
    # ...

    @property
    def service_reports_list(self):
        return self.servicereport_set.all()

定义您自己的列（继承tables.Column）并覆盖render方法

将其添加到您的表类：

class RepairDetailTable(tables.Table):
    # ...
    service_reports_list = YourOwnColumn(some_kwargs)
    # ...

尝试在django_tables2中插入带有外部字段列表的新列
