Laravel的Eloquent表与父母“继承”

Question

I have a Laravel model acl_groups that has a JSON column inherits. What should I do, the "laravel way" to query the inherited groups when checking if a group can do something? The rights are stored in another JSON column, allow/deny so I can just do a in_array to check a single group if they have access.

Answer 1

On your model you can set a getter

public function getInheritsAttribute($v)
    {
        return $v ? json_decode($v, true) : [];
    }

OR if you dont want a getter you can try a pseudo getter

public function getPseudoAttribute()
        {
            return $this->inherits ? json_decode($this->inherits, true) : [];
        }

Kind of maybe did mistake on second one.

And on other model the same thing so when you call $item->inherits = you will get an array First you may try to prepare the array like removing same keys or values

and after just check

if (array_key_exists('thing_to_check', $item->inherits)) {
    return true;
}

This is not a working code, it is just an idea how you can do you. Take a look at Cartalyst Sentinel how they check the permissions for groups and users.
