Accessing Configuration Values on &quot;config/database.php&quot;

Level 27

@SergioGregorutti I think you are using the Illuminate\Config\Repository namespace, use the Facade instead:

use Config:

....
..........
Config::get('world.name');

@usman I tried and I get this error:

"Fatal error: Class 'Config' not found in /home/vagrant/Code/argemundo/config/database.php on line 60"

I put the "use Config;" on "app/database.php" just before the "return [".

Did you try the config helper ?

@SergioGregorutti , I missed the point that you are using Config inside the database.php. It is not possible to use Config facade inside the Configuration files, because internally laravel registers the facades after the configurations. You can use the config helper though:

config('world.name');

Im sorry, this is not resolved yet.

When I call the config('value') on "app/database.php" I think the variable is not defined yet, so I get an empty result.

Where I need to define the Configuration Value to be available in this file?

Currently, Im defining the variable on the boot() method of "AppServiceProvider.php".

@SergioGregorutti Please unmark the answer. This cannot be done apparently, I have been waiting for you to say this. Can you paste your code. I may able to suggest something else.

@usman Sorry, but I can´t unmark the answer. I don´t know if its possible.

This is the code:

AppServiceProvider (Is working fine):

...
use Illuminate\HTTP\Request;
use Illuminate\Config\Repository as Config;
...
public function boot(Request $request, Config $config)
{
    // Set global variables for all Worlds.
    $domain = $request->root();
    switch($domain) {
        case "http://local.argemundo.com":
            $config->set('world.name', 'Mundo Hurlingham');
            $config->set('world.city', 'Hurlingham');
            $config->set('world.id', 'hurlingham');
            break;
    }
}
...

app/database.php (The "world.id" is empty):

...
'database'  => 'am_'.config('world.id'),
...

Level 3

By the way, if I use "config('world.id')" on a view I can see the correct value. The problem is in "app/database.php".

Level 27

@SergioGregorutti of course you will get the value inside the view, config files are loaded before the AppServiceProvider or any other ServiceProvider so the value is not being set in the database.php.

@usman Got it :)

So, now I´m scratching my head thinking on how can I use different databases depending on the domain hehe

@SergioGregorutti did you try:

    switch($domain) {
        case "http://local.argemundo.com":
    ............
    //mysql for instance.
            $config->set('database.connections.mysql.database', 'am_hurlingham');
            break;
    }

This would work, not sure if this suits your needs.

It worked!!! Thanks @usman ! You're my hero today haha

@SergioGregorutti You are welcome :)

@usman Whoops! It's 90% resolved...

When I run for example "php artisan migrate:reset" the "config('world.id')" is empty. I can´t believe it... hehe

I don´t have any idea of how can I set the variable before "artisan" is ready...

Well, I don´t have even a domain when I run the artisan.

@SergioGregorutti It is because your logic inside the boot method depends on the Http request.
