Laravel主键查询不起作用

Question

I have a users table with ID column as primary key. I have this function in a Controller:

public function show($id)
    {
         $items=user::all()->where('ID',$id);
        foreach ($items as $item) 
             echo $item->Name;
    }

This function doesn't echo anything. If I change from $id to $name like this: $items=user::all()->where('Name',$name); it returns what should return. ID is primary key in the table, it's not a fillable field in the Model. If i put ID in the fillable array it doesn't work either. It doesn't work even if I hardcode the id like this $items=user::all()->where('ID','22');

What could be the problem ?

Answer 1

all() will run the query and return a collection of models, instead you should add the where call first and then use get() (or first() )

$items = User::where('ID', $id)->get();
