Or if you want to be like the original example, where the form is
global for all users, make the FormBuilder instance once, and always
return the same thing. There's lots of ways you could do that, but the
easiest way is:
- def child_form(self, ctx):
- return FormBuilder()
+ child_form = FormBuilder()
