如何添加django-reversion到使用django和django-rest框架开发的应用程序 [英] How to add django-reversion to an app developed using django and django-rest framework

问题描述

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。

我已经尝试过 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。

以下是应用程序的模块，我想将Django-reversion包含在还原对象（如果被删除）中。如何设置以下模块的django-reversion配置

admin.py： -

  from django.contrib import admin 
 from.models import类别
 
 admin.site.register（类别）
  

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 
  

.py： -

  from rest_framework import serializers 
 from .models import类别
 
 class CategorySerializer（serializers.ModelSerializer）：
 courses = serializers.HyperlinkedRelatedField（
 many = True 
 read_only = True 
 view_name ='course-detail'
）
 class Meta：
 model =类别
 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_patter ns（[
 
 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类别
来自.serializers import CategorySerializer 
 
 class CategoryViewSet （viewsets.ModelViewSet）：
 queryset = Category.objects.all（）
 serializer_class = CategorySerializer 
 permission_classes =（permissions.IsAuthenticatedor ReadOnly，）
  




解决方案

< a href =http://django-reversion.readthedocs.org/en/latest/api.html#revisionmiddleware =nofollow>创建修订版的最简单的方法是使用reversion.middleware.RevisionMiddleware 。这将自动将每个请求包装在修订版本中，确保您的模型的所有更改都将添加到其版本历史记录中。

要启用修订中间件，只需将其添加到您的 MIDDLEWARE_CLASSES 设置如下：





  MIDDLEWARE_CLASSES =（
'reversion.middleware.RevisionMiddleware'，
＃其他中间件在这里... 
）
  

任何更复杂的事情都需要通过您的代码添加API调用，包含特定保存调用的方式， em>你决定。

I have an app developed using Django and Django Rest framework. I would like to add the django-reversion feature to my app.

I have already tried http://django-reversion.readthedocs.org/en/latest/api.html#low-level-api but I have failed to make specific changes to my app.

Below are the modules of the app where I would like to include the Django-reversion to restore objects if they get deleted. How to set the django-reversion configuration for the below modules

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,)

解决方案

The simplest way to create revisions is to use reversion.middleware.RevisionMiddleware. This will automatically wrap every request in a revision, ensuring that all changes to your models will be added to their version history.

To enable the revision middleware, simply add it to your MIDDLEWARE_CLASSES setting as follows:

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

Any thing more complex with this will require adding API calls through your code in away that wraps specific save calls in ways that you decide.
