在Django中，如何覆盖“保存并继续”功能？ [英] In Django, how to override the 'Save and continue' feature?

问题描述

我需要在ModelAdmin中添加一些保存前和保存后的逻辑，但是仅当用户通过保存并继续编辑按钮而非保存按钮提交表单时。我该怎么做？

I need to add some pre- and post-save logic to my ModelAdmin, but only when the user submitted the form via the 'Save and continue editing' button and not the 'Save' button. How can I do this?

推荐答案

就像覆盖普通的保存方法一样，您需要覆盖您的ModelAdmin中的save_model（）函数，其中包括请求 object 。从请求对象，您可以获取 POST 对象，该对象将包括'_ continue' 键，如果用户单击了保存并继续按钮。示例：

Just like overriding the normal save method, you need to override the save_model() function in your ModelAdmin, which includes the request object. From the request object you can get the POST object, which will include a '_continue' key if the user clicked the 'Save and continue button'. Example:

class MyAdmin(admin.ModelAdmin):
    def save_model(self, request, obj, form, changed):
        if '_continue' in request.POST:
            # add your code here
        return super(ServerAdmin, self).change_view(request, obj, form, changed)
