Eloquent Query Scope return Builder instead of Mod

问题:

I have the following code

$user = User::findByAccountCode($transaction->account_code);

When I execute this code on phpunit it returns an instance of Illuminate\Database\Eloquent\Builder instead of User Model.

Here is the code for findByAccountCode

public function scopeFindByAccountCode($query,$account_code){


   return $query->where('account_code', $account_code)->first();

}

I get the following error on my Application

ErrorException: Argument 1 passed to aunicaj\Libraries\MarkupRepository::user() must be an instance of aunicaj\Models\User, instance of Illuminate\Database\Eloquent\Builder given

When I use the browser its working fine but not on phpunit. Thank you

You're using query scopes incorrectly. They should never fetch any records (this is what your call to first() is doing) - they are only allowed to update the query with adding/removing constraints.

Replace

public function scopeFindByAccountCode($query,$account_code){
  return $query->where('account_code', $account_code)->first();
}

with

public function scopeFindByAccountCode($query,$account_code){
  return $query->where('account_code', $account_code);
}

and use it everywhere like the following:

$user = User::findByAccountCode($transaction->account_code)->first();

If you want to have a method in your User method that would return a user for given account code, feel free to create it, but don't start its name with scope, e.g.:

public static function scopeFindByAccountCode($account_code){
  return static::where('account_code', $account_code)->first();
}

This way your code will work as you wanted - call the following to get a single user:

$user = User::findByAccountCode($transaction->account_code);

I got the problem solve turns out that my factory method in my test is using

factory(User::class)->make() 

it should be

factory(User::class)->create()
