Note on the "It would be best if i didn't have to add any extra fields to the model, but if i really have to i can." 

Sorry, but order of information in a database is determined by the information itself: you always have to add a column for ordering. There's really no choice about that. 

Further, to retrieve things in this order, you'll need to specifically add <code>.order_by(x)</code> to your queries or add <code>ordering</code> to your model.

<pre><code>class InOrder( models.Model ):
 position = models.IntegerField()
 data = models.TextField()
 class Meta:
 ordering = [ 'position' ]
</code></pre>

Without the additional field ordering cannot happen. It's one of the rules of relational databases.

You may try this snippet <a href="https://gist.github.com/barseghyanartur/1ebf927512b18dc2e5be" rel="nofollow">https://gist.github.com/barseghyanartur/1ebf927512b18dc2e5be</a> (originally based on this snippet <a href="http://djangosnippets.org/snippets/2160/" rel="nofollow">http://djangosnippets.org/snippets/2160/</a>).

Integration is very simple.

Your model (in models.py):

<pre><code>class MyModel(models.Model):
 name = models.CharField(max_length=255)
 order = models.IntegerField()
 # Other fields...

 class Meta:
 ordering = ('order',)
</code></pre>

You admin (admin.py):

<pre><code>class MyModelAdmin(admin.ModelAdmin):
 fields = ('name', 'order',) # Add other fields here
 list_display = ('name', 'order',)
 list_editable = ('order',)

 class Media:
 js = (
 '//code.jquery.com/jquery-1.4.2.js',
 '//code.jquery.com/ui/1.8.6/jquery-ui.js',
 'path/to/sortable_list.js',
 )
</code></pre>

Change the JS (of the snippet) accordingly if your attributes responsible for holding the name and ordering are named differently in your model.

blocks|key|1750546|text|在模型类中，您可能必须添加"+order“字段，以保持特定的顺序(例如：order+=+10是最后一个，order+=1是第一个)。然后，您可以在管理change_list模板(请参阅this)中添加JS代码来维护拖放功能。最后，将模型的Meta中的排序更改为类似“order”的内容。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1750547|entityMap|0|LINK|mutability|MUTABLE|url|http://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-media-definitions^0|2K|4|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

In model class you would probably have to add "order" field, to maintain specific order (eg. item with order = 10 is the last one and order = 1 is the first one). Then you can add a JS code in admin change_list template (see <a href="http://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-media-definitions" rel="nofollow noreferrer">this</a>) to maintain drag&amp;drop feature. Finally change ordering in Meta of model to something like ['order'].

blocks|key|1535900|text|只有在模型中添加字段时，才能确定顺序。让我们在模型中添加位置字段。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1535901|In+your+models.py+

The order can only be determined if you add a field in your model.Let's add a position field in your model. 

<pre><code>In your models.py 

class MainModel(models.Model):

 name = models.CharField(max_length=255)
 position = models.PositiveSmallIntegerField(null=True)

 class Meta:
 ordering = ('position',)

In your apps admin.py

class IdeaCardTagInline(nested_admin.NestedStackedInline):
 model = MainModel
 extra = 0
 min_num = 1
 sortable_field_name = "position"
</code></pre>

<code>ordering = ('position',)</code> in Meta will order the MainModel according to the value in the position field. 
<code>sortable_field_name = "position"</code> will help in autofill of the value in position when an user drag and drop the multiple models. 

To see the same order in your api, use order_by(x) in views_model.py.
Just a model example:

<pre><code>Model.objects.filter().order_by('position').
</code></pre>

Say I have a blogging app in Django. How can i re-order the posts using a draggable table in the default admin?

It would be best if i didn't have to add any extra fields to the model, but if i really have to i can.

假设我在Django有一个博客应用程序。如何在默认管理中使用可拖动表重新排序帖子？如果我不需要向模型中添加任何额外的字段，那将是最好的，但如果真的有必要的话，我可以这样做。
