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'].

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.

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.
