Maybe we could get Massimo to post the typical workflow for a request (the
new book draft image on Page 6 --- really makes things clear).
The way to think of this: the return on index actually passes it's return
to the View (mapped by web2py to match the view for the request).
If you read this as
def index():
send dict() -> view.default.index.html()
then you will see this is correct. For "send dict( form=form )" you are
saying the view's 'form' variable will recieve the controller's form
variable. Since in this example, the body of the index view does not
output the value of any of it's variables (only constants - it is using a
variable for loop control, but is outputing a constant string 5 times), this
is unnecessary.
If somewhere you had in the view ... {{=form}} (which you read as
"output the value of form) then your index() controller would need to have
something valid to pass, e.g. something that would logically say something
along the lines of:
send dict( view.form = controller.form )
I hope I'm not taking too many liberties with paraphrasing what this is all
really saying.
Does this make sense now?
