If you want to redirect with form input, you can use the withInput() function
return back()->withInput();
https://laravel.com/docs/7.x/redirects#creating-redirects
Now, this function is designed to be used with form validation and may not be what you want.
What I have done in the past when combining create & edit views into a single template is something like this:
{!! Form::text('name', isset($model) ? $model->name : null, [
'class' => 'form-control',
'placeholder' => 'Please fill out this field &hellips;',
'required' => true
]) !!}
This uses the Laravel Collective HTML library. However the principle is the same if you are using raw hmtl like so:
<input type="text" value="{{ isset($model) ? $model->name : null }}">

You aren't returning a variable called $article to your edit.blade.php.
Round 3 Apple Tree
Originally, you appeared to be calling both a controller action AND also a callback function. Stick to the controller action only like so:
Route::get('/home/edit/{id}','Controller_Article_parents#edit')->name('edit');
Then within your edit() function on the Controller you will want to do this:
public function edit ($id) {
return view('/home/edit', [
'article' => Article::find($id)
]);
}
