# Manipulate data
This page shows you various ways to manipulate the data shown in your BREADs.
## Filters
Read more about filters [here](../plugins/#filter)
## Scopes
You can apply a scope to every layout in a BREAD.
The [Laravel documentation](https://laravel.com/docs/eloquent#local-scopes) shows you how to implement them.
For Voyager to recognize your scope, please make sure to follow the naming convention `scope[X]`, for example `scopeActive`.
You can now select the scope you want to use in the layout options:
::: info
Because Voyager doesn't know which [view](views) you use in combination with which [list](lists), you **should** also apply the scope to your views to prevent users from manually setting URL parameters and using entries they are not supposed to.

## Computed properties
Computed properties allow you to display and edit properties that don't physically exist in your database.
### Getting data
To get the data to be shown when browsing, simply create an [accessor](https://laravel.com/docs/eloquent-mutators#defining-an-accessor) as described in the Laravel docs.
Please be aware that an accessor has to be named `get[X]Attribute` (for example `getFullNameAttribute`) to be recognized by Voyager.
### Setting data
If you want to be able to edit and/or add the data of a non-existing property, you **have** to create a [mutator](https://laravel.com/docs/eloquent-mutators#defining-a-mutator).
When used in a list, an accessor is sufficient.
The mutator also has to follow the naming convention `set[X]Attribute`, for example `setFullNameAttribute`.
### Using your computed property
Now that you created an accessor (and a mutator when you want to edit/add), you can simply select your accessor in the `Column` dropdown.
