django inline formset preserve values after invalid form submission

[hot fiber]

i think the issue might be because of name, when i render {{form.description}} the name is set like form-3-description, form-2-description, form-1-description
but with {{form.description.name}} its always description

You probably want to check how you're ibstantiating the form in python.
The usual flow to preserve data is instantiate the form with the post data, check its valid and then send that same instance back to the view if its invalid. That way it's got the data and errors associated with it.
