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。有没有更好的方式来实现这一点，而不是添加一些JavaScript代码，将重载加载时间的行动？

Answer 1

我想你可以覆盖ModelAdmin中的get_action_choices()方法。

class MyModelAdmin(admin.ModelAdmin): 
    def get_action_choices(self, request, default_choices=BLANK_CHOICE_DASH): 
     """ 
     Return a list of choices for use in a form object. Each choice is a 
     tuple (name, description). 
     """ 
     choices = [] + default_choices 
     for func, name, description in six.itervalues(self.get_actions(request)): 
      choice = (name, description % model_format_dict(self.opts)) 
      choices.append(choice) 
     return choices 

Answer 2

1.Override的get_action_choices()方法在ModelAdmin，清除默认空白选择和重新排序列表。

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，专业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。 所以如果你的动作名称是“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)
