django - 设置 Django 管理员默认操作

Question

我想将名为“--------”(BLANK_CHOICE_DASH)的默认选定操作更改为另一个特定操作。有没有比添加一些会在加载时覆盖操作的 javascript 代码更好的方法来实现这一点？

Answer 1

1.覆盖ModelAdmin中的get_action_choices()方法，清除默认的空白选择并重新排序列表。

class YourModelAdmin(ModelAdmin):
    def get_action_choices(self, request):
    choices = super(YourModelAdmin, self).get_action_choices(request)
    # choices is a list, just change it.
    # the first is the BLANK_CHOICE_DASH
    choices.pop(0)
    # do something to change the list order
    # the first one in list will be default option
    choices.reverse()
    return choices

2.具体action.Override ModelAdmin.changelist_view，使用extra_context更新action_form

ChoiceField.initial 用于设置默认选择的选项。所以如果你的 Action 名称是“print_it”，你可以这样做。

class YourModelAdmin(ModelAdmin):
    def changelist_view(self,request, **kwargs):
        choices = self.get_action_choices(request)
        choices.pop(0)  # clear default_choices
        action_form = self.action_form(auto_id=None)
        action_form.fields['action'].choices = choices
        action_form.fields['action'].initial = 'print_it'
        extra_context = {'action_form': action_form}
        return super(DocumentAdmin, self).changelist_view(request, extra_context)
