Sortable Trait
Adds sortable behavior to Eloquent (Laravel) models
Usage
Add position
field to your model (see below how to change this name):
Add \AlexCrawford\Sortable\SortableTrait
to your Eloquent model.
if you want to use custom column name for position, set $sortableField
:
Now you can move your entities with methods moveBefore($entity)
and moveAfter($entity)
(you dont need to save
model after that, it has saved already):
Also this trait automatically defines entity position on the create
event, so you do not need to add position
manually, just create entities as usual:
This entity will be at position entitiesMaximumPosition + 1
To get ordered entities use the sorted
scope:
Note : Resorting does not take place after a record is deleted. Gaps in positional values do not affect the ordering of your lists. However, if you prefer to prevent gaps you can reposition your models using the
deleting
event. Something like:You need alexcrawford-sortable >=2.3 to use
->next()
Sortable groups
if you want group entity ordering by field, add to your model
now moving and ordering will be encapsulated by this field.
If you want group entity ordering by many fields, use as an array:
Sortable many to many
Let's assume your database structure is
and you want to order tags for each post
Add position
column to the pivot table (you can use any name you want, but position
is used by default)
Add \AlexCrawford\Sortable\BelongsToSortedManyTrait
to your Post
model and define belongsToSortedMany
relation provided by this trait:
Note:
$this->belongsToSortedMany
has different signature then$this->belongsToMany
-- the second argument for this method is$orderColumn
('position'
by default), next arguments are the same
Attaching tags to post with save
/sync
/attach
methods will set proper position
Getting related model is sorted by position
You can reorder tags for given post
Many to many demo: http://sortable5.boxfrommars.ru/posts (code)
You can also use polymorphic many to many relation with sortable behavour by using the MorphsToSortedManyTrait
trait and returning $this->morphToSortedMany()
from relation method.
By following the Laravel polymorphic many to many table relation your tables should look like
And your model like
Sortable Controller
Also this package provides \AlexCrawford\Sortable\SortableController
, which handle requests to sort entities
Usage
Add the service provider to config/app.php
publish the config:
Add models you need to sort in the config config/sortable.php
:
Add route to the sort
method of the controller:
Now if you post to this route valid data:
Then entity with \Input::get('id')
id will be moved relative by entity with \Input::get('positionEntityId')
id.
For example, if request data is:
then the article with id 3 will be moved after the article with id 14.

Note: Laravel 5 has csrf middleware enabled by default, so you should setup ajax requests: http://laravel.com/docs/5.0/routing#csrf-protection
