我有一个使用Django和Django Rest框架开发的应用程序。我想将django-reversion功能添加到我的应用程序中。

我已经尝试http://django-reversion.readthedocs.org/en/latest/api.html#low-level-api,但我未能对我的应用进行具体更改。

下面是应用程序的模块,如果它们被删除,我希望包含Django-reversion来恢复对象。如何为以下模块设置django-reversion配置

admin.py: -

from django.contrib import admin
from.models import Category

admin.site.register(Category)

models.py: -

  from django.db import models
  class Category(models.Model):
     name = models.CharField(max_length=64, unique=True)

     def __unicode__(self):
         return self.name

serializers.py: -

        from rest_framework import serializers
        from .models import Category

        class CategorySerializer(serializers.ModelSerializer):
              courses = serializers.HyperlinkedRelatedField(
                  many=True
                  read_only=True
                  view_name='course-detail'
               )
               class Meta:
                     model = Category
                     fields = ('pk', 'name', 'courses',)

urls.py: -

            from django.conf.urls import patterns, url
            from rest_framework.urlpatterns import format_suffix_patterns
            from .import views
            from django.conf.urls import include

            category_list = views.CategoryViewSet.as_view({
                'get': 'list',
                'post': 'create'
            })

            category_detail = views.CategoryViewSet.as_view({
                'get': 'retrieve',
                'put': 'update',
                'patch': 'partial_update',
                'delete': 'destroy',
           })

           urlpatterns = format_suffix_patterns([

                url(r'^categories/$',
                    category_list,
                    name='category-list'),
                url(r'^categories/(?P<pk>[0-9]+)/$',
                    category_detail,
                    name='category-detail'),
           ])

           urlpatterns += [
               url(r'^api-auth/', include('rest_framework.urls',
                                          namespace='rest_framework')),
           ]

views.py: -

from rest_framework import permissions
from rest_framework import viewsets
from .models import Category
from .serializers import CategorySerializer

class CategoryViewSet(viewsets.ModelViewSet):
 queryset = Category.objects.all()
 serializer_class = CategorySerializer
 permission_classes = (permissions.IsAuthenticatedorReadOnly,)

The simplest way to create revisions is to use reversion.middleware.RevisionMiddleware。这将自动包装修订中的每个请求,确保将对模型的所有更改添加到其版本历史记录中。

     

要启用修订中间件,只需将其添加到MIDDLEWARE_CLASSES设置,如下所示:

MIDDLEWARE_CLASSES = (
    'reversion.middleware.RevisionMiddleware',
    # Other middleware goes here...
)

任何更复杂的事情都需要通过您的代码添加API调用,以您决定的方式包装特定的save调用。

<强> admin.py

from django.contrib import admin
from.models import Category
import reversion

class BaseReversionAdmin(reversion.VersionAdmin):
 pass

admin.site.register(Category, BaseReversionAdmin)

还添加了对installed_apps和middlewareclasses的恢复。

最后,我可以看到&#34;恢复删除的对象按钮&#34;。
