Question

我想知道是否有办法在用户进行更改时覆盖管理面板中的值？

方案：我有一个带有两个字段的模型，last_edited_by和last_edited_date。我想要做的是当用户对条目进行更改时自动填充这两个字段。

尝试：这里有一些代码允许我打印其中一个字段的值，但即使应用了新值，管理面板也没有变化。

admin.py

class ProcessSheetRefAdmin(admin.ModelAdmin):

    def change_view(self, request, object_id, form_url='', extra_context=None):
        obj = super(ProcessSheetRefAdmin, self).get_object(request, object_id)

        if obj is not None:
            """
                attempting to update the value in last_edited_date, 
                but even after applying new value, the admin panel shows old value from 
                last database entry.
            """
            obj.last_edited_date = time.time() 

        if request.method == 'POST':
            print "admin post"

        return super(ProcessSheetRefAdmin, self).change_view(request, object_id, form_url, extra_context)

admin.site.register(ProcessSheetRefrence, ProcessSheetRefAdmin)

任何帮助都将不胜感激!!

当您对obj进行更改时，需要在此之后保存。

    if obj is not None:
        """
            attempting to update the value in last_edited_date, 
            but even after applying new value, the admin panel shows old value from 
            last database entry.
        """
        obj.last_edited_date = time.time()
        obj.save()

当用户在管理视图中进行更改时，如何在Django中覆盖ModelAdmin值？
