Commands

Create layout

To create a new layout you can run the command below.

Create templates

Prepare

Nova Resource

You can use the getFlex() method to get all the layouts that are provided with this package and the layouts that you created yourself. If you want to manualy add flexibles to your Nova resource, please reference the manual usage section of this readme.

Models

Make sure your model will cast this data correctly by adding this to the field of your model.

Customize

Title on Layout classes

Sometimes its very hard to see which group is what because all items look the same. It is possible to get a value from one of the fields to be displayed in the group overview. By default the title field will be used but it can be overriten.

Title on custom layouts

Config Methods

You can call a load config method once you've created your flexible field to change the behaviour of the flexible field. Below you will find some examples.

Helpers

You can overrule a lot of defaults with the methods below.

The Layouts Collection

Collections returned by the FlexibleCast cast and the HasFlexible trait extend the original Illuminate\Support\Collection. These custom layout collections expose a find(string $name) method which returns the first layout having the given layout $name.

The Layout instance

Layouts are some kind of fake models. They use Laravel's HasAttributes trait, which means you can define accessors & mutators for the layout's attributes. Furthermore, it's also possible to access the Layout's properties using the following methods:

name()

Returns the layout's name.

title()

Returns the layout's title (as shown in Nova).

key()

Returns the layout's unique key (the layout's unique identifier).

Going further

When using the Flexible Content field, you'll quickly come across of some use cases where the basics described above are not enough. That's why we developed the package in an extendable way, making it possible to easily add custom behaviors and/or capabilities to Field and its output.

Custom Layout Classes

Sometimes, addLayout definitions can get quite long, or maybe you want them to be shared with other Flexible fields. The answer to this is to extract your Layout into its own class. See the docs for more information on this.

Predefined Preset Classes

In addition to reusable Layout classes, you can go a step further and create Preset classes for your Flexible fields. These allow you to reuse your whole Flexible field anywhere you want. They also make it easier to make your Flexible fields dynamic, for example if you want to add Layouts conditionally. And last but not least, they also have the added benefit of cleaning up your Nova Resource classes, if your Flexible field has a lot of addLayout definitions. See the docs for more information on this.

Custom Resolver Classes

By default, the field takes advantage of a JSON column on your model's table. In some cases, you'd really like to use this field, but for some reason a JSON attribute is just not the way to go. For example, you could want to store the values in another table (meaning you'll be using the Flexible Content field instead of a traditional BelongsToMany or HasMany field). No worries, we've got you covered!

Tell the field how to store and retrieve its content by creating your own Resolver class, which basically just contains two simple methods: get and set. See the docs for more information on this.

Usage with nova-page

Maybe you heard of one of our other packages, nova-page, which is a Nova Tool that allows to edit static pages such as an "About" page (or similar) without having to declare a model for it individually. More often than not, the Flexible Content Field comes in handy. Don't worry, both packages work well together! First create a nova page template and add a flexible content to the template's fields.

As explained in the documentation, you can access nova-page's static content in your blade views using {{ Page::get('attribute') }}. When requesting the flexible content like this, it returns a raw JSON string describing the flexible content, which is of course not very useful. Instead, you can simply implement the Marshmallow\Nova\Flexible\Concerns\HasFlexible trait on your page Templates, which will expose the Page::flexible('attribute') facade method and will take care of the flexible content's transformation.
