The FORM section of the book specifically mentions add_button, right
before the SQLFORM section. If it only works with SQLFORM, that should
be moved. If it does work with FORM, a trivial example would be good
right there.

I think it is a method of SQLFORM. FORM() is a web2py helpers, it unique role
is generate html. SQLFORM is another beast. Maybe further reading of the book
could help you better
understand the difference :

And it's only just now I realize that "months" is a set, not a list.
Changing it to ['January', ...] solves the order.
I'm still curious why add_button does not work with a simple FORM(),
though.

This generates a random-hashed order also (although I had to add
more months to see it):
months = {'January', 'February', 'March', 'April', 'May', 'June'}
buttons = []
for month in months:
buttons.append(TAG.button(month, _type="button"))
form = SQLFORM.factory(db=None, buttons=buttons)
That may not be what you meant.

Why not using SQLFORM.factory() and get the new buttons
attributes that let you manage as many buttons as you want? It also let you
manage buttons
positions much more easilly then
manipulate the generated form.

Trying to generate a small form that is all buttons:
def month-example:
months = {'January', 'February', 'March'}
form = FORM()
for month in months:
# this fails
form.add_button(month, URL(month))
return dict(form=form)
This generates 'NoneType' object has no attribute
'parent'.
Creating links with helpers works:
form += A( month, _href=URL(month) )
But the form is a dictionary, and the months are out of
order. I think that add_button preserves the order, but have not verified that.
Does add_button only work with SQLFORM?
How can the order of elements added to a form
programmatically be controlled?
