Django-Admin:集成自定义表单

Question

我正在尝试将CS​​V文件的导入表单构建到给定模型的管理界面中.可以从模型的change_list到达视图,但它会引发模板语法错误.

我究竟做错了什么？我是否必须创建自己的模板,或者我可以以某种方式重新使用现有的admin/change_form.html而我只是不明白？

您肯定需要使用自己的模板,或修改更改表单,但也需要修改更改视图.例如,将此导入添加到更改表单本身应该是微不足道的.

Django的管理员为其管理员使用了许多神奇的东西,这些模板有许多标签,这些标签特定于通过其更改/更改列表视图传入的对象.

admin/base_site.html相反延伸,你很高兴.
