如何在Laravel中定义模型数据

Question

I need to save project_id in to task table according to the relevant projects from using Project model.

Project Model

public function scopeProject($query, $id)
{
    return $query->where('project_id', $id);
}

Now I am going to save to task table using store method in TaskController as following

public function store(Request $request, $id, Task $task)// this is line 45
{
    $task = new Task;
    $task->task_name   = $request->input('name');
    $task->body = $request->input('body');
    $task->assign          = $request->input('status');
    $task->priority        = $request->input('status');
    $task->duedate  = date("Y-m-d", strtotime($request->input("date")));// $request->input('date');
    $task->project_id        = $id;
    $task->save();
}

But when I am going to save this data following error is occurred

ErrorException in TasksController.php line 45: Argument 3 passed to App\Http\Controllers\TasksController::store() must be an instance of App\Task, none given

Then how can I grab project_id from using Project Model to My TaskController?

Answer 1

I got result in this way..... TaskController

public function postNewTask(Request $request,$id, Project $project)
{

    $task = new Task;
    $task->task_name   = $request->input('name');
    $task->body = $request->input('body');
    $task->assign = $request->input('status');
    $task->priority = $request->input('status');
    $task->duedate  = date("Y-m-d", strtotime($request->input("date")));
    $task->project_id = $id;
    $task->save();

form url

<form  method="post" action="{{ route('projects.tasks.create', $project->id) }}">

and routes

Route::post('projects/{projects}/tasks', [
    'uses' => '\App\Http\Controllers\TasksController@postNewTask',
    'as' => 'projects.tasks.create'
]);
