设置Django管理员默认动作

问题描述

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。有没有更好的方法来实现这一点，而不是添加一些JavaScript代码来覆盖加载时间的操作？

I would like to change the default selected action named "---------" (BLANK_CHOICE_DASH) to another specific action. Is there a better way to implement this than adding some javascript code that would override the action in load time?

推荐答案

1.Override您的 ModelAdmin 中的 get_action_choices（）方法，清除默认空白选项并重新排列列表。

1.Override the get_action_choices() method in your ModelAdmin, clear the default blank choice and reorder the list。

class YourModelAdmin(ModelAdmin):
    def get_action_choices(self, request):
    choices = super(DocumentAdmin, 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

2.Specific action.Override ModelAdmin.changelist_view, use extra_context to update action_form

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

ChoiceField.initial used to set the default selected choice.so if your action name is "print_it", you can do this.

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)
