Can you make a scope in laravel that calls various other scopes?

Question

I have a model in Laravel that has various scopes defined. I want to use all of them in a lot of places so rather than chaining them together I'd rather just be able to call one scope that calls all of the other scopes like so:

function scopeValid($query, $user_id) {
    $query = $this->scopeDateValid($query);
    $query = $this->scopeMaxUsesValid($query);
    $query = $this->scopeCustomerMaxUsesValid($query, $user_id);
    return $query;
}

This doesn't seem to work though, is there a way to achieve this?

Answer 1

As shown in the docs, you'll want to do your scoping against $query, not $this, and use the scope's magic function rather than calling the internal implementation:

public function scopeTesting($query) {
    return $query->testingTwo();
}

public function scopeTestingTwo($query) {
    return $query->where('testing', true);
}

As a demonstration, you can see here calling the testing() scope applies the logic in the testingTwo() scope:

>>> App\User::testing()->toSql();
=> "select * from "users" where "testing" = ?"
>>> 

So, for your code, this should do the trick:

function scopeValid($query, $user_id) {
    $query = $query->dateValid();
    $query = $query->maxUsesValid();
    $query = $query->customerMaxUsesValid($user_id);

    return $query;

    // or just return $query->dateValid()
    //                      ->maxUsesValid()
    //                      ->customerMaxUsesValid($user_id);
}
