How to Translate the Backend

EasyAdmin leverages the Symfony Translation component to provide built-in support for translating backends into any language. The translation process is divided into two steps:

• Translating the elements of the EasyAdmin interface;
• Translating your own contents (such as the main menu and the property labels).

The elements of the interface are translated using the EasyAdminBundle domain. The rest of the elements are translated using the default messages domain.

Before translating your backend, make sure that the translator service is enabled in the application (projects based on the Symfony Standard Edition have it disabled by default):

# app/config/config.yml
framework:
    translator: { fallbacks: [ "en" ] }

Translate the Backend Interface

The backend interface uses the same language as the underlying Symfony application. If you want to change it, update the value of the locale option in the app/config/parameters.yml file.

EasyAdmin is already translated into tens of languages thanks to the generosity of its community. We're actively looking for more translations, so please consider contributing a translation for your own language.

NOTE

Although it's not recommended to do it, if you want to change any of the built-in translations defined under the EasyAdminBundle domain, use the translation override mechanism provided by Symfony.

Translate the Main Menu Labels

Menu items use the entity name as their label. The entity name is the YAML key used to define the configuration of each entity. For example, the following configuration would show two menu items called Customers and Orders:

# app/config/config.yml
easy_admin:
    entities:
        Customers:
            class: AppBundle\Entity\User
        Orders:
            class: AppBundle\Entity\Purchase

The messages.xx.yml (or messages.xx.xlf) file for the previous example would need to use Customers and Orders as the keys of the translations. Example:

# app/Resources/translations/messages.es.yml
Customers: Clientes
Orders: Ventas

Main menu labels can be customized thanks to the label option of each entity. You can even use structured translation keys instead of the real contents:

# app/config/config.yml
easy_admin:
    entities:
        Customers:
            label: app.menu.customers
            class: AppBundle\Entity\User
        Orders:
            label: app.menu.orders
            class: AppBundle\Entity\Purchase

In this case, the translation file should use the value of the label option as the keys of the translations (and you should also create the file for the original language used by the translation keys):

# app/Resources/translations/messages.en.yml
app.menu.customers: Customers
app.menu.orders: Orders

# app/Resources/translations/messages.es.yml
app.menu.customers: Clientes
app.menu.orders: Ventas

Translate Property Labels

The behavior of the property labels is very similar to the one explained in the previous section for the main menu. By default, the label of each property is the "humanized" version of its name:

Property value	Default property label
propertyname	Propertyname
propertyName	Property name
property_name	Property name

Consider the following configuration:

# app/config/config.yml
easy_admin:
    entities:
        Customer:
            class: AppBundle\Entity\Customer
            list:
                fields: ['firstName', 'lastName']
        # ...

The backend will display First name and Last name as the labels of the properties, so those are the translation keys that must be used:

# app/Resources/translations/messages.es.yml
First name: Nombre
Last name: Apellidos

Alternatively, you can use the label option of each property to define its label explicitly. You can even use structured translation keys instead of the real contents:

# app/config/config.yml
easy_admin:
    entities:
        Customer:
            class: AppBundle\Entity\Customer
            list:
                fields:
                    - { property: 'firstName', label: 'app.users.firstName' }
                    - { property: 'lastName', label: 'app.users.lastName' }
        # ...

In this case, the translation file should use the value of the label option as the keys of the translations (and you should also create the file for the original language used by the translation keys):

# app/Resources/translations/messages.en.yml
app.menu.firstName: First name
app.menu.lastName: Last name

# app/Resources/translations/messages.es.yml
app.menu.firstName: Nombre
app.menu.lastName: Apellidos

Translate Custom Templates

All the built-in templates include the following tag to set EasyAdminBundle as the defualt domain used to translate the contents of that template:

{% trans_default_domain "EasyAdminBundle" %}

When overriding templates in any of your views or properties, make sure to add this tag at the top of each file to not break the backend internationalization. If needed, you can also define any other translation domain and skip the default one in your templates:

{{ 'content_to_translate' | trans({}, 'MyCustomTranslationDomain') }}

The above template uses the translations defined in the app/Resources/translations/MyCustomTranslationDomain.en.xlf file (replace en by your locale and xlf by the desired translation format) instead of the default EasyAdmin translations.
