Updating Resources

This section is deprecated. However, as of now, the Sylius E-Commerce project is still resorting to this configuration so you might want to check it out.

To display an edit form of a particular resource, change it or update it via API, you should use the updateAction action of your app.controller.book service.

Yaml

config/routes.yaml

app_book_update:
    path: /books/{id}/edit
    methods: [GET, PUT]
    defaults:
        _controller: app.controller.book::updateAction

PHP

src/Entity/Book.php

use Sylius\Resource\Annotation\SyliusRoute;

#[SyliusRoute(
    name: 'app_book_update',
    path: '/books/{id}/edit',
    methods: ['GET', 'PUT'],
    controller: 'app.controller.book::updateAction',
)]

Done! Now when you go to /books/5/edit, ResourceController will use the repository (app.repository.book) to find the book with id == 5. If found it will create the app_book form, and set the existing book as data.

Submitting the Form

You can use exactly the same route to handle the submit of the form and updating the book.

<form method="post" action="{{ path('app_book_update', {'id': book.id}) }}">
    <input type="hidden" name="_method" value="PUT" />

On submit, the update action with method PUT, will bind the request on the form, and if it is valid it will use the right manager to persist the resource. Then, by default it redirects to app_book_show to display the updated book, but like for creation of the resource - it's customizable.

When validation fails, it will simply render the form again, but with error messages.

Changing the Template

Just like for other actions, you can customize the template.

Yaml

config/routes.yaml

app_book_update:
    path: /books/{id}/edit
    methods: [GET, PUT]
    defaults:
        _controller: app.controller.book::updateAction
        _sylius:
            template: Admin/Book/update.html.twig

PHP

src/Entity/Book.php

use Sylius\Resource\Annotation\SyliusRoute;

#[SyliusRoute(
    name: 'app_book_update',
    path: '/books/{id}/edit',
    methods: ['GET', 'PUT'],
    controller: 'app.controller.book::updateAction',
    template: 'Admin/book/update.html.twig',
)]

Using Custom Form

Same way like for createAction you can override the default form.

Yaml

config/routes.yaml

app_book_update:
    path: /books/{id}/edit
    methods: [GET, PUT]
    defaults:
        _controller: app.controller.book::updateAction
        _sylius:
            form: App\Form\BookType

PHP

src/Entity/Book.php

use App\Form\BookType;
use Sylius\Resource\Annotation\SyliusRoute;

#[SyliusRoute(
    name: 'app_book_update',
    path: '/books/{id}/edit',
    methods: ['GET', 'PUT'],
    controller: 'app.controller.book::updateAction',
    form: BookType::class,
)]

Passing Custom Options to Form

Same way like for createAction you can pass options to the form.

Below you can see how to specify custom options, in this case, validation_groups, but you can pass any option accepted by the form.

Yaml

config/routes.yaml

app_book_update:
    path: /books/{id}/edit
    methods: [GET, PUT]
    defaults:
        _controller: app.controller.book::updateAction
        _sylius:
            form:
                type: app_book_custom
                options:
                    validation_groups: [sylius, my_custom_group]

PHP

src/Entity/Book.php

use App\Form\BookType;
use Sylius\Resource\Annotation\SyliusRoute;

#[SyliusRoute(
    name: 'app_book_update',
    path: '/books/{id}/edit',
    methods: ['GET', 'PUT'],
    controller: 'app.controller.book::updateAction',
    form: [
        'type' => BookType::class,
        'validation_groups' => ['sylius', 'my_custom_group'],
    ],
)]

Overriding the Criteria

By default, the updateAction will look for the resource by id. You can easily change that criteria.

Yaml

config/routes.yaml

app_book_update:
    path: /books/{title}/edit
    methods: [GET, PUT]
    defaults:
        _controller: app.controller.book::updateAction
        _sylius:
            criteria: { title: $title }

PHP

src/Entity/Book.php

use App\Form\BookType;
use Sylius\Resource\Annotation\SyliusRoute;

#[SyliusRoute(
    name: 'app_book_update',
    path: '/books/{id}/edit',
    methods: ['GET', 'PUT'],
    controller: 'app.controller.book::updateAction',
    criteria: [
        'title' => '$title',
    ],
)]

Custom Redirect After Success

By default the controller will try to get the id of resource and redirect to the "show" route. To change that, use the following configuration.

Yaml

config/routes.yaml

app_book_update:
    path: /books/{id}/edit
    methods: [GET, PUT]
    defaults:
        _controller: app.controller.book::updateAction
        _sylius:
            redirect: app_book_index

PHP

src/Entity/Book.php

use App\Form\BookType;
use Sylius\Resource\Annotation\SyliusRoute;

#[SyliusRoute(
    name: 'app_book_update',
    path: '/books/{id}/edit',
    methods: ['GET', 'PUT'],
    controller: 'app.controller.book::updateAction',
    redirect: 'app_book_index',
)]

You can also perform more complex redirects, with parameters. For example:

Yaml

config/routes.yaml

app_book_update:
    path: /genre/{genreId}/books/{id}/edit
    methods: [GET, PUT]
    defaults:
        _controller: app.controller.book::updateAction
        _sylius:
            redirect:
                route: app_genre_show
                parameters: { id: $genreId }

PHP

src/Entity/Book.php

use App\Form\BookType;
use Sylius\Resource\Annotation\SyliusRoute;

#[SyliusRoute(
    name: 'app_book_update',
    path: '/genre/{genreId}/books/{id}/edit',
    methods: ['GET', 'PUT'],
    controller: 'app.controller.book::updateAction',
    redirect: [
        'route' => 'app_genre_show',
        'parameters' => ['id' => '$genreId'],
    ],
)]

Custom Event Name

By default, there are two events dispatched during resource update, one before setting new data, the other after successful update. The pattern is always the same - {applicationName}.{resourceName}.pre/post_update. However, you can customize the last part of the event, to provide your own action name.

Yaml

config/routes.yaml

app_book_customer_update:
    path: /customer/book-update/{id}
    methods: [GET, PUT]
    defaults:
        _controller: app.controller.book::updateAction
        _sylius:
            event: customer_update

PHP

src/Entity/Book.php

use App\Form\BookType;
use Sylius\Resource\Annotation\SyliusRoute;

#[SyliusRoute(
    name: 'app_book_customer_update',
    path: '/customer/book-update/{id}',
    methods: ['GET', 'PUT'],
    controller: 'app.controller.book::updateAction',
    event: 'customer_update',
)]

This way, you can listen to app.book.pre_customer_update and app.book.post_customer_update events. It's especially useful, when you use ResourceController:updateAction in more than one route.

[API] Returning resource or no content

Depending on your app approach it can be useful to return a changed object or only the 204 HTTP Code, which indicates that everything worked smoothly. Sylius, by default is returning the 204 HTTP Code, which indicates an empty response. If you would like to receive a whole object as a response you should set a return_content option to true.

Yaml

config/routes.yaml

app_book_update:
    path: /books/{title}/edit
    methods: [GET, PUT]
    defaults:
        _controller: app.controller.book::updateAction
        _sylius:
            criteria: { title: $title }
            return_content: true

PHP

src/Entity/Book.php

use App\Form\BookType;
use Sylius\Resource\Annotation\SyliusRoute;

#[SyliusRoute(
    name: 'app_book_update',
    path: '/books/{title}/edit',
    methods: ['GET', 'PUT'],
    controller: 'app.controller.book::updateAction',
    criteria: ['title' => '$title'],
    returnContent: true,
)]

Warning

The return_content flag is available for the applyStateMachineTransitionAction method as well. But these are the only ones which can be configured this way. It is worth noticing, that the applyStateMachineTransitionAction returns a default 200 HTTP Code response with a fully serialized object.

                arguments: [$title, expr:service('app.context.book')]
            criteria:
                enabled: true
                genreId: $genreId
            redirect:

                parameters: { title: resource.title }
            return_content: true

Remember that you can use controller's Fully Qualified Class Name (App\Controller\BookController) instead of id app.controller.book
