Django-Admin：整合自定义表单 [英] Django-Admin: integrating custom forms

问题描述

我正在为给定模型的管理界面建立一个CSV文件的导入表单。可以从模型的change_list访问视图，但会引发模板语法错误。

I am trying to build a import form for a CSV file into the admin interface for a given model. the view can be reached from the change_list of the model, but it throws a template syntax error.

我做错了什么？我必须创建自己的模板，或者我可以重新使用现有的admin / change_form.html，但是我不明白吗？

What am I doing wrong? Do I have to create my own template or can I re-use the existing admin/change_form.html somehow and I just don't get it?

推荐答案

您绝对需要使用自己的模板，或修改更改表单，但也可以修改更改视图。例如，将此导入添加到更改表单本身中应该是微不足道的。

You definitely need to use your own template, or modify the change form but also modify the change view. For example, it should be trivial to add this import into the change form itself.

Django的管理员为其管理员使用了很多神奇的东西，这些模板有很多标签这些特定于通过其更改/更改列表视图传递的对象。

Django's admin uses a lot of magical things for its admin, and those templates have many tags that are specific to the objects passed in via its change/changelist views.

代替延长 admin / base_site.html ，你很好。
