This never happened to me and I find it very strange. Maybe it's a bug or
maybe it's the intended behaviour, but I find it REALLY strange.
Consider a widget which, for some reason, raises an exception:
class CoolWidget(AdminTextareaWidget):
def render(self, name, value, attrs={}):
WRONG()
return super(JsonSchemaWidget, self).render(name, value, attrs)
The widget is included in an admin form like:
class PizzaForm(forms.ModelForm):
class Meta:
model = Pizza
exclude = []
widgets = {'toppings': CoolWidget}
class PizzaAdmin(ModelAdmin):
form = TemplateForm
Now, if DEBUG is True, trying to open the relative pizza change or add form
will result in:
NameError: name 'WRONG' is not defined
When DEBUG to False what I see is really strange:
I get an empty change/add form!

Now suppose that the condition that raises the exception happens only on a
remote server
which has DEBUG=False. The exception happens because the configuration of a
django project
has not been updated correctly yet.
Instead of failing loud, it will fail silently, leaving an empty add/change
form.
Is it the intended behaviour? Or a bug?
I guess it is related due to the fact that template errors are silenced.
