[albatross-users] ctx.req_equals() question.

[Michael C. Neel]

>From the docs, req_equals() returns whether or not the browser request
contains a non-empty field with a name which matches the name argument.
But I've noticed that if you leave a field blank on a form, submit it,
have it return to the same form and submit it again, req_equals will be
true for the empty field.

In my case I have and edit account page to update your account.  On the
page is a change password / confirm password set of inputs.  If they are
empty I don't want to wipe out the users password, just up date the
contact info.  The second submission will however wipe out the password.
To prevent this, my code looks like this:

	if ctx.req_equals("password") and ctx.req_equals("confirm"):
		if ctx.locals.password == ctx.locals.confirm and
len(ctx.locals.password) != 0:
			# change password

It would seem to me that the "and len(ctx.locals.password) != 0" should
not be needed.  I don't know if this is intended or not, I could be
missing something about the intended use of req_equals().
