eloquent

问题 I need to make a raw database query using Laravel: $results = DB::select("SELECT * FROM members INNER JOIN (several other tables) WHERE (horribly complicated thing) LIMIT 1"); I get back a plain PHP StdClass Object with fields for the properties on the members table. I'd like to convert that to a Member (an Eloquent model instance), which looks like this: use Illuminate\Database\Eloquent\Model; class Member extends Model { } I'm not sure how to do it since a Member doesn't have any fields set

问题 I'm using eloqent to filter a set of products: Product::whereIn('color', $color)->whereIn('size', $size)->whereIn('price', $price)->get(); Each of the above variables is an array of ids $color = [1,2,4,5] My question is, is this inefficient when the user fails to send through a set of variables, say they did not want any color filters so the array would be: $color = []; I've tried ->toSql and it produces the sql statement: select * from `products` where `color` in (?, ?) and 0 = 1 and `price`

问题 Hypothetical situation: Let's say we have 3 models: User Role Permission Let's also say User has a many-to-many relation with Role , and Role has a many-to-many relation with Permission . So their models might look something like this. (I kept them brief on purpose.) class User { public function roles() { return $this->belongsToMany(Role::class); } } class Role { public function users() { return $this->belongsToMany(User::class); } public function permissions() { return $this->belongsToMany

问题 Here is what I try to do: $q = Question::where('id',$id -> id)->get(); $q[] = $q->push([ 'test' => true]); dd($q); This will output: Collection {#220 ▼ #items: array:3 [▼ 0 => Question {#225 ▶} 1 => array:1 [▼ "test" => true ] 2 => null ] } So 'test' => true will append as a new key, but I want to insert it in Question so latter I can access to it like this with foreach $q -> test So here is how I want access to item: @foreach($q as $qq) {{ $qq->test }} @endforeach 回答1: It can be done by
