Django ModelForm：如何覆盖或检查“save_as” [英] Django ModelForm: How to override or check for "save_as"

问题描述

我需要添加一些自定义，例如Django Admin中的一个实例是saved_as一个副本。可以在 save（）中执行此操作，如果是，请检查 save_as kwarg ？
或者有一个 save_as（）方法我可以覆盖某处。我无法找到任何关于常规 save（）与 save_as = True

I need to add some customizations for the case that a instance in Django Admin is "saved_as" a copy. Can I do that in save(), if so how do I check for the save_as kwarg? Or is there a save_as() method I can override somewhere. I was not able to find any information about the differences in the process between a regular save() and one with save_as = True.

有人可以给我一个例子，或给我一个提示去哪里？

Can someone point me to an example or give me an hint where to go?

谢谢你非常喜欢你的时间！

Thank you very much for your time!

另存为新按钮是一个提交元素，一个特定的名称 _saveasnew ，这意味着您可以通过 _saveasnew POST参数的存在来检查该按钮是否被按下。

The Save as New button is a submit element with a specific name, _saveasnew, meaning you can check whether that button was pressed via the presence of the _saveasnew POST parameter.

def change_view(self, request, object_id, extra_context=None):        
    if '_saveasnew' in request.POST:
        # custom logic for save as new
        print "I am saved as new"
    return super(ModelAdmin, self).change_view(request, object_id, extra_context)
