Description

ziffmedia/laravel-eloquent-imagery takes a unique approach to handling images. Instead of treating images as model relations, they are treated as attributes of a model. To this end, image information is stored in a tables column (a model's attribute) at a given name. Additionally, this library handles image modifications (resizing, triming, backgrounds) when serving the image instead of at upload time. Images are stored in any of the configured kinds of file storage that Laravel supports.

Features:

• images are tracked in same table's column
• setup is handled by adding a trait and a method per image type
• modifications can be made by manipuliating the image's url
• placeholder generation is supported
• fallback to a placeholdler (mainily for dev purposes) is supported when the image is not on the disk

Other Good Libraries

If this solution to the image problem does not appeal to you, Spatie's MediaLibrary is an excellent library that both treats images as Models as a Relation, and also has a concept of "conversions" that can be applied at upload time.

Installation

First, install the package:

$ composer require ziffmedia/laravel-eloquent-imagery

In Laravel 5.5+. this library will self-register. Next, you should publish the vendor (config) files:

$ artisan vendor:publish --provider="ZiffMedia\LaravelEloquentImagery\EloquentImageryProvider"

It is now ready to use.

Usage

Attaching An Image To A Model

In the simplest use case for a single image attached to a model, first create a json column in a migration to handle this image:

// in a table migration
$table->json('image')->nullable();

Next, in the model, add in the HasEloquentImagery trait and configure a class property called $eloquentImagery like so:

use ZiffMedia\LaravelEloquentImagery\Eloquent\HasEloquentImagery;

class Post extends Model
{
    use HasEloquentImagery;

    protected $eloquentImagery = [
        'path' => 'posts/{id}.{extension}',
    ];
}

Attaching an Image Collection To A Model

An Image Collection is a ordered list of Image objects. The collection itself when hydrated has images that are indexable starting at 0. Each collection has a concept of an auto increment number which is stored in the collection (and the collection's serialization) so that Image objects can take advantage of this in the path template.

In the simplest use case, using a json column like in the direct image scenario above, add in the HasEloquentImagery trait as before, and use the eloquentImageryCollection method at construction to setup the collection:

use ZiffMedia\LaravelEloquentImagery\Eloquent\HasEloquentImagery;

class Post extends Model
{
    use HasEloquentImagery;

    protected $eloquentImagery = [
        'images' => [
            'path' => 'post/{id}/image-{index}.{extension}',
            'collection' => true
        ],
    ];
}

Displaying An Image In A View

The following blade syntax assumes $post is a Model of type Post with an image attribute. This will generate a url similar to /imagery/post/11/image.png:

@if($bam->image->exists)
    <img src="{{ $bam->image->url() }}" width="20" />
@endif

Using modifiers when generating the url, a url generated such as /imagery/post/11/image.@[e-mail]

@if($bam->image->exists)
    <img src="{{ $bam->image->url('size200x200|trim) }}" width="20" />
@endif

Detailed Configuration

The following table describes the available configuration options:

eloquent-imagery.filesystem

Default: env('IMAGERY_FILESYSTEM', 'public')

This is the filesystem images will be stored on at the image's path.

eloquent-imagery.render.enable

Default: true

Whether or not to enable the render route and modification functionality.

eloquent-imagery.render.path

Default: /imagery

The path prefix the route will live at and serve images from.

eloquent-imagery.render.placeholder.enable

Default: env('IMAGERY_RENDER_PLACEHOLDER_ENABLE', false)

Highly useful for dev purposes, consider enabling in local.

eloquent-imagery.render.placeholder.filename

default value _placeholder_

This identifies when a placeholder image is being requested.

eloquent-imagery.render.placeholder.use_for_missing_files

default value env('IMAGERY_RENDER_PLACEHOLDER_USE_FOR_MISSING_FILES', false)

If an image is requested that is not on the filesystem, enabling this will serve a placeholder instead (useful for dev).

eloquent-imagery.render.caching.enable

default value env('IMAGERY_RENDER_CACHING_ENABLE', true)

Whether or not the controller should use full request caching

eloquent-imagery.render.caching.driver

default value env('IMAGERY_RENDER_CACHING_DRIVER', 'disk')

Cache to the disk.

eloquent-imagery.render.caching.ttl

default value 60

How long the ttl for the cache is.

eloquent-imagery.render.browser_cache_max_age

default value 31536000

How long the browser should cache the image generated by this route for.

eloquent-imagery.force_unmodified_image_rendering

default value env('IMAGERY_FORCE_UNMODIFIED_IMAGE_RENDERING', false)

This will allow for the dynamic (controller) route or static route (link to storage, for example) to be selectively used based on if modifiers are present in the image request

Demo

Once cloned, cd demo directory. Inside there do the following:

composer install
artisan migrate
artisan db:seed
artisan serve

If you wish to demo the Nova specific capabilities, you must first install the downloadable version of nova to demo/nova. Once it is there, continue with the above script from the top, then visit the examples at /nova in your browser.

TODO

• support moving images as a result of updated path parts (attribute update, etc)

Updating

Updating to 0.5.0

• make sure to rename the config/eloquent_imagery.php to config/eloquent-imagery.php, probably a good idea to re-copy the original (or publish again).
• see the new method of configuring a model to use an image: use a property called $eloqentImagery
