Do I need to append every generated bundle to composer.json manually? - symfony

Question

I've started to learn Symfony and I am following some tutorials where there is nothing about this:
When I create a new project with symfony installer and run composer install and then php app/console server:start I can open that project in my browser.
BUT! When I create a new bundle with command php app/console generate:bundle I get this error message:
PHP Fatal error: Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "BlogBundle" from namespace "BlogBundle".
Did you forget a "use" statement for another namespace? in /home/user/Symfony/myapp/app/AppKernel.php:19
And then I need to go to my composer.json file and append my new generated bundle after AppBundle like this
{
"name": "user/myapp",
"license": "proprietary",
"type": "project",
"autoload": {
"psr-4": {
"AppBundle\\": "src/AppBundle",
"BlogBundle\\": "src/BlogBundle" // <-- this is the new appended one
},
"classmap": [
"app/AppKernel.php",
"app/AppCache.php"
]
},
..........
And then when I try to start the server again it works and it shows Hello world in my browser.
So the question is do I have to do this every time (append new generated bundle in composer.json file)?

Answer 1

Yes. This is the reason, why you usually have an namespace above that. Some abbreviation of your name or company for example. This way you only add that namespace for the src folder and all bundles are "found" automatically.
Example:
{
...
"autoload": {
"psr-4": {
"Acme\\": "src"
},
}
...
}
Now of course your bundles need to use that namespace, eg.:
namespace Acme\BlogBundle;
class BlogBundle {
}
