The reason you don’t want to do this is because someone can change your disabled field to enabled and then submit the form. You would have to change the save function as to not insert the “disabled” data.
The standard way to do this is to not put the name in an input, but to display it as text
<form>
<div>
<label>Name</label>
<p>Johnny Five</p>
</div>
<div>
....
This is not possible in django.
I say if you really trust your userbase to not “mess” with things then go for it, but if its a public facing website with possible sensitive data then stay away.
