New in Symfony 4.1: Misc. improvements (part 2)
Warning: This post is about an unsupported Symfony version. Some of this information may be out of date. Read the most recent Symfony Docs.
In Symfony 4.1, the CountryType, CurrencyType, LanguageType and
LocaleType form fields define a new
choice_translation_locale option to
change the locale used to translate their lists of elements. In previous Symfony
versions, elements were always translated to the current locale:
1 2 3 4
$formBuilder->add('country', CountryType::class, [ // translate elements into Spanish, regardless of the current locale 'choice_translation_locale' => 'es', ]);
Added a command to delete cache pool items
Pierre du Plessis
In Symfony 4.1, there is a new
cache:pool:delete command that allows you to
delete specific items from the cache pool. This is mostly useful while developing
the application, to not delete the entire cache pool when you only need to clear
$ php bin/console cache:pool:delete <cache-pool-name> <cache-key-name>
Use custom functions in
In complex applications, the
access_control security config can include
security expressions defined with the ExpressionLanguage component:
1 2 3 4 5 6 7
# config/packages/security.yaml security: # ... access_control: - path: ^/_internal/secure allow_if: "'127.0.0.1' == request.getClientIp() or has_role('ROLE_ADMIN')"
In Symfony 4.1,
allow_if expressions can also include any
custom ExpressionLanguage functions defined in your application.
dd() debug helper
Using a debugger connected to your code editor is the best way to debug your
applications. However, sometimes a call to the dump() function can be as
effective as the debugger and much faster to execute. In Symfony 4.1 we
introduced a helper called
dd() that dumps the given information and stops
the application immediately, which is a common workflow when debugging apps:
1 2 3
dd($user, $request); // equivalent to: // dump($user, $request); exit(1);
Help the Symfony project!
As with any Open-Source project, contributing code or documentation is the most common way to help, but we also have a wide range of sponsoring opportunities.
