Example of CRUD with one to one relationship and image upload laravel - php

Question

I am having trouble understanding and knowing how to create a one to one relationship with CRUD and file upload together, is it possible to give me a simple example on how to do it? Because when I tried to do it, for some reason my id and user_id doesn't match at all
Example, in user_info table (jack with id 1) has one userImage table(image uploaded with a user_id = 1).
This is the part that I am having trouble with in my controller:
public function store1(Request $request){
$this->validate($request, [
'input_img' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
$user_info = Session::get('data');
$UserImage = new UserImage($request->input()) ;
if($file = $request->hasFile('input_img')) {
$file = $request->file('input_img');
$fileName = $file->getClientOriginalExtension() ;
$destinationPath = public_path().'/images' ;
$file->move($destinationPath,$fileName);
$UserImage->userImage = $fileName ;
$UserImage = UserImage::create(['file' => $request->file('input_img')]);
$UserImage->user_infos()->associate($user_info);
}
$UserImage->save() ;
//dd($UserImage);
return redirect('/home');
}

Sample of one to one relationship. I wish it can help you.
Example of table of Column of user table:
id
name
email
password
Example of table of Column of userimage table:
id
user_id
image_link
uploaded
User Model
public function userImage()
{
return $this->hasOne(App\UserImage::class);
}
UserImage Model
public function user()
{
return $this->hasOne(App\User::class);
}
CRUD in controller
public function store(Request $request)
{
$user = new App\User;
$user->name = $request->name;
$user->email = $request->email;
$user->password = $request->password;
$user->save();
$user->userImage->create([
'image_link' => $request->image,
'uploaded' => $request->date,
]);
return back();
}
public function update(Request $request, $id)
{
$user = App\User::find($id);
$user->name = $request->name;
$user->email = $request->email;
$user->password = $request->password;
$user->save();
$user->userImage->image_link = $request->image;
$user->userImage->uploaded = $request->date;
$user->userImage->save();
return back();
}
public function destroy($id)
{
$user = App\User::find($id)->delete();
return back();
}

Create a foreign key in your user_info table referencing userImage table.
Create unique constraint on the foreign key.
