Informations about the package symfony-addons
vrok/symfony-addons
This is a library with additional classes for usage in combination with the Symfony framework.
Mailer helpers
Automatically set a sender address
We want to replace setting the sender via mailer.yaml as envelope (@see https://symfonycasts.com/screencast/mailer/event-global-recipients) as this would still require each mail to have a FROM address set and also doesn't allow us to set a sender name.
config/services.yaml:
.env[.local]:
Messenger helpers
Resetting the logger before/after a message
We want to group all log entries belonging to a single message to be grouped with a distinct UID and to flush a buffer logger after a message was processed (successfully or failed), to immediately see the entries in the log:
config/services.yaml:
Validators
AtLeastOneOf
Works like Symfony's own AtLeastOneOf constraint, but instead of returning a message like
This value should satisfy at least ...
it returns the message of the last failed validation.
Can be used for obviously optional form fields where only simple messages should be
displayed when AtLeastOne
is used with Blank
as first constraint.
See AtLeastOneOfValidatorTest
for examples.
NoHtml
This validator tries to detect if a string contains HTML, to allow only plain text.
See NoHtmlValidatorTest
for examples of allowed / forbidden values.
NoLineBreak
This validator raises a violation if it detects one or more linebreak characters in
the validated string.
Detects unicode linebreaks, see NoLineBreaksValidatorTest
for details.
NoSurroundingWhitespace
This validator raises a violation if it detects trailing or leading whitespace or
newline characters in the validated string. Linebreaks and spaces are valid within the string.
Uses a regex looking for \s
and \R
, see NoSurroundingWhitespaceValidatorTest
for details on detected characters.
PasswordStrength
This validator evaluates the strength of a given password string by determining its entropy
instead of requireing something like "must contain at least one uppercase & one digit
& one special char".
Allows to set a minStrength
to vary the requirements.
See Vrok\SymfonyAddons\Helper\PasswordStrength
for details on the calculation.
PHPUnit helpers
Using the ApiPlatformTestCase
This class is used to test ApiPlatform endpoints by specifying input data and verifying the response data. It combines the traits documented below to refresh the database before each test, optionally create authenticated requests and check for created logs / sent emails / dispatched messages. It allows to easily check for expected response content, allowed or forbidden keys in the data or to verify against a given schema.
Requires "symfony/browser-kit" & "symfony/http-client" to be installed (and of cause ApiPlatform).
Option | Usage | Example |
---|---|---|
skipRefresh | if set & true the database will not be refreshed before the request, to allow using two calls to `testOperation` in one testcase, e.g. uploading & deleting a file with two requests | `'skipRefresh' => true` |
prepare | Callable, to be executed _after_ the kernel was booted and the DB refreshed, but _before_ the request is made | |
uri | the URI / endpoint to call | `'uri' => '/users'` |
iri | an array of `[classname, [field => value]]` that is used to fetch a record from the database, determine its IRI, which is then used as URI for the request | `'iri' => [User::class, [email => '[email protected]']]` |
if given, tries to find a User with that email and sends the request authenticated as this user with lexikJWT bundle | `'email' => '[email protected]'` | |
postFormAuth |
if given (and 'email' is set) the JWT from Lexik is sent as 'application/x-www-form-urlencoded'
request in a form field. This is used for download endpoints where the browser should present the user with the file to download instead of loading it into memory via Javascript. (As we don't want to supply the token via GET to prevent security issues and as we cannot set a cookie.) |
`'postFormAuth' => 'bearer'` |
method | HTTP method for the request, defaults to GET. If PATCH is used, the content-type header is automatically set to `application/merge-patch+json` (if not already specified) | `'method' => 'POST'` |
requestOptions | options for the HTTP client, e.g. query parameters or basic auth | |
files | An array of one or more files to upload. The files will be copied to a temp file, and wrapped in an `UploadedFile`, so the tested application can move/delete it as it needs to. If this option is used, the content-type header is automatically set to `multipart/form-data` (if not already specified) | |
responseCode | asserts that the received status code matches | `'responseCode' => 201` |
contentType | asserts that the received content type header matches | `'contentType' => 'application/ld+json; charset=utf-8'` |
json | asserts that the returned content is JSON and contains the given array as subset | |
requiredKeys | asserts the dataset contains the list of keys. Used for elements where the value is not known in advance, e.g. ID, slug, timestamps. Can be nested. | |
forbiddenKeys | like requiredKeys, but the dataset may not contain those | |
schemaClass | Asserts that the received response matches the JSON schema for the given class. If the `iri` parameter is used or the request method is *not* GET, the item schema is used. Else the collection schema is used. | |
createdLogs | array of entries, asserts the messages to be present (with the correct log level) in the monolog handlers after the operation ran | |
emailCount | asserts this number of emails to be sent via the mailer after the operation was executed | |
messageCount | asserts this number of messages to be dispatched to the message bus | |
dispatchedMessages | Array of message classes, asserts that at least one instance of each given class has been dispatched to the message bus. An Element can also be an array of [FQCN, callable], in that case the callback is called for each matching message with that message as first parameter and the JSON response as second parameter, to trigger additional assertions for the message. | |
dispatchedEvents | Array of event names (may be class names), asserts that at least one instance of each given event has been dispatched to Symfony's EventDispatcher. |
Using the RefreshDatabaseTrait
(Re-)Creates the DB schema for each test, removes existing data and fills the tables
with predefined fixtures.
Install doctrine/doctrine-fixtures-bundle
and create fixtures,
the trait uses the test group per default.
Just include the trait in your testcase and call bootKernel()
or
createClient()
, e.g. in the setUp method:
Optionally define which fixtures to use for this test class:
Supports setting the cleanup method after tests via DB_CLEANUP_METHOD
. Allowed values
are purge and dropSchema, for more details see RefreshDatabaseTrait::$cleanupMethod
.
Using the AuthenticatedClientTrait
For use with an APIPlatform project with lexik/jwt-authentication-bundle
.
Creates a JWT for the user given by its unique email, username etc. and adds it
to the test client's headers.
Include the trait in your testcase and call createAuthenticatedClient
:
Using the MonologAssertsTrait
For use with an Symfony project using the monolog-bundle.
Requires monolog/monolog
of v3.0 or higher.
Include the trait in your testcase and call prepareLogger
before triggering the
action that should create logs and use assertLoggerHasMessage
afterwards to check
if a log record was created with the given message & severity:
Workflow helpers
Require symfony/workflow
.
PropertyMarkingStore
Can be used instead of the default MethodMarkingStore
, for entities
& properties without Setter/Getter.
workflow.yaml:
services.yaml:
WorkflowHelper
Allows to get an array of available transitions and their blockers, can be used to show the user what transitions are possible from the current state and/or why a transition is currently blocked.
Cron events
Adding this bundle to the bundles.php
registers three new CLI commands:
When these are called, they trigger an event (CronHourlyEvent
, CronDailyEvent
,
CronMonthlyEvent
) that can be used by one ore more event listeners/subscribers to do
maintenance, push messages to the messenger etc.
It is your responsibility to execute these commands via crontab correctly!
ApiPlatform Filters
SimpleSearchFilter
Selects entities where the search term is found (case insensitive) in at least one of the specified properties. All specified properties type must be string.
Requires CAST as defined Doctrine function, e.g. by vrok/doctrine-addons
:
ContainsFilter
Postgres-only: Filters entities by their jsonb fields, if they contain the search parameter,
using the @>
operator. For example for filtering for numbers in an array.
Requires CONTAINS as defined Doctrine function, provided by vrok/doctrine-addons
:
JsonExistsFilter
Postgres-only: Filters entities by their jsonb fields, if they contain the search parameter,
using the ?
operator. For example for filtering Users by their role, to prevent accidental
matching with overlapping role names (e.g. ROLE_ADMIN and ROLE_ADMIN_BLOG) when searching as
text with WHERE roles LIKE '%ROLE_ADMIN%'
.
Requires JSON_CONTAINS_TEXT as defined Doctrine function, provided by vrok/doctrine-addons
:
MultipartDecoder
Adding this bundle to the bundles.php
registers the MultipartDecoder
to allow handling of file uploads with additional data (e.g. in ApiPlatform):
The decoder is automatically called for multipart
requests and
simply returns all POST parameters and uploaded files together. To enable
this add the multipart
format to your config\api_platform.yaml
:
FormDecoder
Adding this bundle to the bundles.php
registers the FormDecoder
to allow handling HTML form data in ApiPlatform:
The decoder is automatically called for form
requests and
simply returns all POST parameters. To enable this add the form
format to your
config\api_platform.yaml
:
Twig Extensions
Adding this bundle to the bundles.php
together with the symfony/twig-bundle
registers the new extension:
FormatBytes
Converts bytes to human-readable notation (supports up to TiB).
This extension is auto-registered.
In your Twig template:
Outputs: 9.34 MiB
