django - Django Admin:如何访问admin.py中的list_display方法的请求对象？

Question

我在模型的admin.py类中添加了highlight_link方法:

class RadioGridAdmin(admin.ModelAdmin):
    
    list_display = ('start_time', highlight_link)
    
    def highlight_link(self):
        return ('some custom link')
    
    
admin.site.register(RadioGrid, RadioGridAdmin)

它为更改列表中返回的每个记录返回一个自定义链接(为简便起见，我省略了 highlight_link.short_description)。太好了但我想检查当前的查询字符串并基于此更改自定义链接。有没有办法在 highlight_link中访问请求对象？

Answer 1

我这样解决我的问题。

class MyClassAdmin(admin.ModelAdmin):

    def queryset(self, request):
        qs = super(MyClassAdmin, self).queryset(request)
        self.request = request
        return qs

现在我可以在任何地方使用 self.request
更新

Changed in Django 1.6: The get_queryset method was previously named queryset.

class MyClassAdmin(admin.ModelAdmin):

    def get_queryset(self, request):
        qs = super(MyClassAdmin, self).get_queryset(request)
        self.request = request
        return qs
