Symfony crud edict : Could not load type "datetime"

Question

Context:

I create a project with symfony 3. My database have one table with a field datetime

With this commands I create a simple CRUD application for one table

php bin/console doctrine:mapping:import --force adminBundle xml

php bin/console doctrine:mapping:convert annotation ./src

php bin/console doctrine:generate:entities adminBundle

php bin/console generate:doctrine:crud

Error:

So my crud is done but when I edit one row throw an error

Could not load type "datetime" 500 Internal Server Error - InvalidArgumentException

Stack Trace

  in vendor/symfony/symfony/src/Symfony/Component/Form/FormRegistry.php at line 87

I think that could not load type “datetme”, I try register my form in the section services of my services.yml, but I don't know How to do it? for the type datetime.

Any idea? thanks in advance.

Answer 1

Seems like a bug in the CRUD generator. It uses a type alias instead of the fully qualified class name:

$builder->add('fieldName', 'textarea');

The fully qualified class name is required since Symfony 3.0:

$builder->add('fieldName', DateTimeType::class);

Please check the generated form type.

Answer 2

Sergey, thanks for pointing that out. I'm not sure why, but specifying the fully qualified class name didn't resolve the issue on my end. Removing the datetime alias all together did.

Changed:

$builder
  ->add('name')
  ->add('time', 'datetime')
  ->add('location')
;

To:

$builder
  ->add('name')
  ->add('time')
  ->add('location')
;
