        return redirect()->back()->with('success','data inserted');

    }

}

Please Guide me How to Insert Record According To Foreign Key(project_id)

My Answer:
In order to insert a record with a foreign key (project_id) in Laravel, you need to make sure that you are passing the project_id along with the other fields when creating a new Task record.

Here's how you can modify your insert method in the TaskController to include the project_id:

php
public function insert(Request $request)
{
$validation = $request->validate([
'title'=>'required',
'project_id'=>'required', // make sure project_id is required
]);

Task::create($validation);
return redirect()->back()->with('success','data inserted');
}


In your form where you are submitting the data, make sure to include a hidden input field for the project_id. For example:

html

@csrf


Submit

Make sure to replace `$project_id` with the actual project_id value that you want to associate with the Task record.

This way, when you submit the form, the project_id will be included in the request data and the Task record will be created with the correct foreign key.
