[5.2] Add method to implement multiple scopes with variable names

[sileence]

Proposal to add the method scopes to allow the implementation of multiple variable scopes at once, for example:

Post::scopes(['question', 'pending' => true])->get() is the same as:

Post::questions()->pending(true)->get()

I don't see how using an array is in any way better than calling them directly.

Maybe this should be is_int?

[sileence]

sure

@JosephSilber

I have something like this in my code:

        $scopes = $this->getListScopes($request);

        $posts = Post::scopes($scopes)->paginate();

Based on the request I determine the dynamic scope(s) to filter the posts including its parameters. Doing the same with chained methods is not that easy and don't look that nice.

[JosephSilber]

Then this is something very unique to your app, and you should keep it there.

Doesn't make much sense in the framework IMO.

[GrahamCampbell]

Hmmm, I think it could be quite useful. Could make for nicer design rather than making method calls using variables as method names. I'm 👍 here.

Can you send a PR for a test for this?

@sileence This line doesn't work. callScope needs callable type as the first argument, so it should be:

$callable = [$this->model, 'scope'.ucfirst($scope)];

$builder->callScope($callable, (array) $parameters)

Also, scope can return anything, not necessarily a builder instance, so I wouldn't re-assign it here.

[sileence]

working on that.
