Nova 4 Breadcrumbs

This Laravel Nova package extends the breadcrumbs functionality of the First Party Nova breadcrumbs.

Tests repo can be found here: https://github.com/Formfeed-UK/nova-breadcrumbs-tests

Version 2.x Changes

Version 2.x is a significant change from previous versions, this package now augments the existing nova breadcrumbs to offer:

• Static methods on the breadcrumbs class allowing control of breadcrumb generation globally
• Methods on Resources allowing control of breadcrumb generation per resource (per-resource methods override static callbacks)
• Support for resource groups
• Nested resource breadcrumbs

Breaking changes from 1.x

• Will use the Nova 4.19+ Breadcrumbs Vue components
• No Longer uses resource cards (This gives better UX as the breadcrumbs will be sent via the page props as per the built in ones and drops a request)
• Will intercept the Nova Breadcrumbs via middleware
• Can no longer have custom CSS (due to using the Nova components)
• Can no longer use the onlyOn{view}, exceptOn{view} etc permissions methods. Breadcrumb visibility can now be controlled via the callbacks/class methods
• Each breadcrumb will extend the Nova Breadcrumb class, and the array of Breadcrumbs will extend the Nova Breadcrumbs class.

Requirements >= v2.x

• php: >=8.0
• laravel/nova: ^4.19

Requirements <= v1.x

• php: >=8.0
• laravel/nova: ^4.0
• formfeed-uk/nova-resource-cards: ^1.1

Features

This package adds automated breadcrumbs to the top of Nova 4 resources.

It supports:

• belongsTo relationships to build a full set of breadcrumbs to your Nova root.
• Automatic detection of belongsTo relationships, and the ability to specify a relationship as the "parent" relationship
• Linking directly to Resource Tabs in the eminiarts/nova-tabs package (Tab slugs are recommended)
• Linking to either the resource's index or its parent (for relationships included as fields)
• Customising the title and label functions for resources
• Use on Dashboards (only to the extent that the Breadcrumbs show as Home -> {Current Dashboard}). Mainly for UI consistency.
• Methods/Callbacks to control the breadcrumbs generation global or per resource

Installation

1) Install the package in to a Laravel app that uses Nova via composer:

2) Publish the config file (optional)

Usage

General

1) Enable Nova Breadcrumbs in the same way as the first party Nova Breadcrumbs in your NovaServiceProvider boot method:

2) Optionally configure a parent method on your Model to explicitly define the relationship the package should query. The name of this function can be changed in the configuration file.

Resource Methods

You can optionally override the default behaviour of the breadcrumbs package on a per resource basis by adding methods to your Nova Resource. These methods should all return an instance of Breadcrumb or an array of Breadcrumb instances.

• groupBreadcrumb(NovaRequest $request, Breadcrumbs $breadcrumbs, Breadcrumb $groupBreadcrumb) - Override the group breadcrumb for this resource
• indexBreadcrumb(NovaRequest $request, Breadcrumbs $breadcrumbs, Breadcrumb $indexBreadcrumb) - Override the index breadcrumb for this resource
• detailBreadcrumb(NovaRequest $request, Breadcrumbs $breadcrumbs, Breadcrumb $detailBreadcrumb) - Override the detail breadcrumb for this resource
• formBreadcrumb(NovaRequest $request, Breadcrumbs $breadcrumbs, Breadcrumb $formBreadcrumb, $type) - Override the form breadcrumb for this resource, $type is a string referring to the current form type (create, update, attach, replicate etc)
• resourceBreadcrumbs(NovaRequest $request, Breadcrumbs $breadcrumbs, array $breadcrumbArray) - Override the entire set of breadcrumbs for this resource

For Dashboards, you can use the following method:

• dashboardBreadcrumb(NovaRequest $request, Breadcrumbs $breadcrumbs, Breadcrumb $dashboardBreadcrumb) - Override the dashboard breadcrumb for this resource

Example

Static Callbacks

You can override the default behaviour of the breadcrumbs globally by using the following static methods on the Breadcrumbs class. They should be provided within a boot method on a service provider.

These methods will be overriden by any per resource methods.

The closure provided should return either an instance of Breadcrumb or an array of Breadcrumb instances.

• detailCallback(callable $callback)
• indexCallback(callable $callback)
• formCallback(callable $callback)
• resourceCallback(callable $callback)
• dashboardCallback(callable $callback)
• rootCallback(callable $callback)
• groupCallback(callable $callback)

Example

Configuration Options

Please see the included config file for a full list of configuration options (it's well commented).

In addition to these options you can also specify the following options in the resource itself:

Link To parent

This determines if the breadcrumb should link to the parent resource regardless of if the current resource's index is navigable from the main menu:

public static $linkToParent = true|false;

Disable Parent Breadcrumbs

Resolving Parent breadcrumbs can be disabled by adding the following static variable to a resource:

public static $resolveParentBreadcrumbs = false;

Invoking Reflection

Determining the parent via invoking reflected blank model methods and checking the returned type is now disabled by default.

It is highly recommended that this functionality be left off, and either a parent method, form field, or a defined relationship return type be used instead.

However if needed you can still enable this functionality by doing the following:

• If downloading for the first time after 1.0.0 is released, set the invokingReflection configuration option after publishing the config
• If upgrading from 0.1.x add the following to your config: "invokingReflection" => true

You can also set this on a per-resource basis with the following static:

public static $invokingReflection = true|false;

Issues/Todo

• Enable support for Polymorphic/ManyToMany relationships based upon previously visited resources
