Hey,
How "Let's try it! Move over, refresh and... it actually works! It's a text field filled with the firstName of the current author." if in case of deleting the whole EntityType stuff we've have this:
`
$builder->...

        ->add('author', UserSelectTextType::class, [
            'invalid_message' => 'Invalid data type has been pushed.'
        ]);

`
Only this works correctly and there is no firstName at all or something connected to the UserEntity.
What I've missed?

Hey MASQUERADE promotion!

Great question. Here is what happens behind the scenes at this exact moment:

1) Symfony starts rendering the "author" field
2) It sees that the Article.author field is populated by a User object
3) It then looks at the UserSelectTextType and sees that its parent is TextType::class. That means it should render as an input type="text" field
4) It renders the <input type="text"> field. For the value attribute, it literally just tries to print the author field - so it literally tries to print the User object that is on that field. Thanks to the __toString() method on the User object, instead of an error, the firstName is printed.

So, you're right - the form does not have ANY configuration yet to connect it to the User entity. BUT, the Article.author property IS a User object, and so the form tries to render using that value.

I hope this helps!

Cheers!

ok. thanks. Just didn't have that written, while had the __toString() and then wrote you.

I am facing an unknown issue here, I create the custom type same as in the tutorial, User class already have the __toString method, I changed the ArticleFormType's author field as per instructions, my form rendering correctly, but with no value (author firstname is not there), I checked that value in the custom transformer, null was passed there. If I remove the custom type, and leave it to symfony to guess the type, then it renders correctly as dropdown with all user-names, but even if I changed it to TextType, it doesn't show anything (just empty field).

What could be the reason?

Hey Wazir Khan!

Sorry for my super slow reply! Hmm... what does your __toString() method look like? And what does your ArticleFormType look like? I'm looking at a few things... and they all point to this being some, small subtle typo somewhere in your code. It could be in __toString()... though I'm pretty sure that when you let Symfony "guess" the type, it would also use that (but it's actually showing the usernames? That's curious). Anyways, if you're still having the issue, post some code here and we'll get to the bottom of it.

Cheers!
