Tim, this won’t help you to use or solve the formfield_overrides issues, but
maybe it will be helpful. I’ve not tried this for a CharField, but it works
great on a TextField (which has no max_length, so model size isn’t impacted):
1. Install widget tweaks and add {% load widget_tweaks %} at the top of your
HTML page.
2. On your HTML page, instantiate the field using this format: {{
form.notes|attr:"rows:20"|attr:"cols:50" }} - you can use either row/cols or
both as in this case, and any char size.
Here’s a great usage example on widget tweaks:

I hope this is useful for you.

Tim,
I found this in the Django source code on Github searching for
'formfield_overrides'. It is in a test module testing formfield_overrides
functionality. I'm assuming you imported TextInput from forms? This should
work to change your *admin* display. Are trying to change your Admin panel
form or a form going out to the user?
class BandAdmin(admin.ModelAdmin):
formfield_overrides = {
CharField: {'widget': forms.TextInput(attrs={'size': '10'})}
}
I am trying to change a form going to the user.
The form in the admin page __does__ show the size attribute in
the HTML source code for input/text.
So it appears that formfield_overrides only affects the admin
page.
I'm going to call this solved - given that I can "widen" the field
with css.
Thanks again Joe. You've been a great help and I've learned a lot.
cheers
