更改Laravel 4中的默认环境

Question

In Laravel 4 the default configuration environment is 'production'. This means that if you run an artisan command without the --env option, it assumes the production configuration. This can be seen in \\Illuminate\\Foundation\\Application::detectWebEnvironment() which is called by detectConsoleEnvironment() when no --env option is set.

This behavior has become a risk with my development environment. It's really easy to forget the --env option and, say, unintentionally run a migration on your production database. (Yes, that happened but thankfully it was a minor change.) I'm close to just renaming my production environment config to 'real-production' but it seems like there should be a more elegant solution.

TL;DR

How can I change the default environment in Laravel 4 such that artisan commands do not run on production by default?

Answer 1

Thanks Antonio for prompting me to reconsider domain detection.

$env = $app->detectEnvironment(array(
(
    // Empty string is to set development as the default environment for 
    // artisan commands.
    'development' => array('dev.foo.com', ''),
    'test' => array('test.foo.com'),
    'production' => array('www.foo.com', 'foo.com'),
));

Adding '' as a development domain effectively sets development as the default environment for artisan commands, presumably because the domain name is blank when the application is invoked from the command line. I tested and it seems anything == false will work. I also verified this does not interfere with the detection of the production or testing environments.

In bootstrap/start.php you can set the environment:

$env = $app->detectEnvironment(function()
{

    return 'development';

});

But you can do many things like:

$env = $app->detectEnvironment(array(

    'local' => array('your-machine-name'),

));

And

$env = $app->detectEnvironment(function()
{
    return $_SERVER['MY_LARAVEL_ENV'];
});

You can try modifying app/start.php file to add second parameter on desired environment as TRUE ie to enable local environment it looks like

$env = $app->detectEnvironment(array(

    'local' => array('homestead',true),

));

One of the most elegant solution that I've found is from this blog post: http://stevegrunwell.com/blog/laravel-application-environment/

The advantages:

1. No need to hardcode an array of development machines into a git committed file start.php .
2. Fallback to server environmental variables in production.
3. Easy persist local development environment by modifying the environment.php file.

Answer 5

$env = $app->detectEnvironment(array(

      'staging' => array('baichebao_test'),
      'local' => array('*.local', '*'),
 ));

like my example, put your default environment in the last item of array, and add "*" to it's manager hostname. and it works in laravel 4.X

In Laravel 4.2 you will not be able to do destructive artisan migrations without being prompted:

Destructive migration operations now require confirmation or --force when being run in production.
