设置Django管理默认操作

Question

我想要将名为“---------”（BLANK_CHOICE_DASH）的默认选定操作更改为另一个特定的操作。有没有更好的实现方法，而不是添加一些JavaScript代码，在加载时覆盖该操作？

可能是为Django选择字段设置默认值的重复问题。 - solarissmoke

@solarissmoke：那不一样。我想要在管理员操作中。 - d33tah

您只需要覆盖相应的管理表单，就可以应用相同的概念。 - solarissmoke

Answer 1

1. 在您的 ModelAdmin 中覆盖 get_action_choices() 方法，清除默认的空白选项并重新排列列表。

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.具体操作。覆盖ModelAdmin.changelist_view，使用extra_context更新action_form。

ChoiceField.initial用于设置默认选择的选项。 所以如果您的操作名称是"print_it"，您可以这样做。

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)

选择 = super（MyModelAdmin，self）.get_action_choices（request） - Nils Zenker

@NilsZenker 好的，我会修复它。 - xavierskip

在你的 admin.py 文件中

class MyModelAdmin(admin.ModelAdmin):
    def get_action_choices(self, request, **kwargs):
        choices = super(MyModelAdmin, 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

而在你的类中

class TestCaseAdmin(MyModelAdmin):

- Nils Zenker

我认为你可以在ModelAdmin中重写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
