Laravel：如何在视图中按ID访问记录

Question

In my controller I return a view with a ?collection $programs ? from an eloquent query to the view.

Controller

    $programs = ScheduledProgram::where('registration_start_date', '<=', $today) 

    return View::make('admin/register_users/show', compact(programs));     

I wan to do something like this without it running a new query from the view...

VIEW

{{$program->find(id)}}

I know that $programs is a dataset that already has the record, but I don't know the way to access the element by ID this way.

How do I do this?

(sorry, seems like an obviously searchable question but my search terms aren't comming up with the answer)

Answer 1

in that case you need to make a @foreach in $programs to access the data. Like this:

 @foreach($programs as $key => $value)
    {{$value->id}}
 @endforeach

If the return is only one line you can do this:

{{$programs[0]->id}}

Answer 2

1.You have to add the method get (converts the "dataset " in a Laravel collection) to iterate the collection.

$programs = ScheduledProgram::where('registration_start_date', '<=', $today)
             ->get()

2.If you want to get a single record:

ScheduledProgram::where('registration_start_date', '<=', $today)->where('id', 5)->get();
