Django Admin actions

from django.db import modelsSTATUS_CHOICES = (    ('d', 'Draft'),    ('p', 'Published'),    ('w', 'Withdrawn'),)class Article(models.Model):    title = models.CharField(max_length=100)    body = models.TextField()    status = models.CharField(max_length=1, choices=STATUS_CHOICES)    # On Python 3: def __str__(self):    def __unicode__(self):        return self.titlefrom django.contrib import adminfrom myapp.models import Articledef make_published(modeladmin, request, queryset):    queryset.update(status='p')make_published.short_description = "Mark selected stories as published"class ArticleAdmin(admin.ModelAdmin):    list_display = ['title', 'status']    ordering = ['title']    actions = [make_published]admin.site.register(Article, ArticleAdmin)      

但是因为actions和这个Admin是紧耦合的，所以我们把这个函数当做方法卸载Admin内部

actions = ['make_published']def make_published(self, request, queryset):    queryset.update(status='p')make_published.short_description = "Mark selected stories as published"

这里在actions中使用了字符串代替了上面的函数名，表示在make_published是方法。

使用self.message_user来对用户进行提示

使用action来提供一个中间页直接返回一个响应

from django.http import HttpResponsefrom django.core import serializersdef export_as_json(modeladmin, request, queryset):    response = HttpResponse(content_type="application/json")    serializers.serialize("json", queryset, stream=response)    return response

或者重定向

from django.contrib import adminfrom django.contrib.contenttypes.models import ContentTypefrom django.http import HttpResponseRedirectdef export_selected_objects(modeladmin, request, queryset):    selected = request.POST.getlist(admin.ACTION_CHECKBOX_NAME)    ct = ContentType.objects.get_for_model(queryset.model)    return HttpResponseRedirect("/export/?ct=%s&ids=%s" % (ct.pk, ",".join(selected)))

将actions作用于全站,第二个参数是名字.

admin.site.add_action(export_selected_objects, 'export_selected')

禁用actions

admin.site.disable_action('delete_selected')#禁用了自带的删除admin.site.disable_action('delete_selected')                                                                                                       class SomeModelAdmin(admin.ModelAdmin):    actions = ['some_other_action']    ...class AnotherModelAdmin(admin.ModelAdmin):    actions = ['delete_selected', 'a_third_action']    ...

actuions只是ModelAdmin的一个字段,如果想禁用一个ModelAdmin的所有actions

class MyModelAdmin(admin.ModelAdmin):    actions = None

如果想对用一个ModelAdmin下的不用字段或者同一字段对不用用户使用不同的actions,那么就覆盖掉get_actions方法.

返回一个允许的actions字典,keys是action的名字,value是一个(function,name,short_description)的元组.

class MyModelAdmin(admin.ModelAdmin):    ...    def get_actions(self, request):        actions = super(MyModelAdmin, self).get_actions(request)        if request.user.username[0].upper() != 'J':            if 'delete_selected' in actions:                del actions['delete_selected']                                                                             return actions
