yes, you are right, my bad, my old code have a race condition because of
assigned with max id
*e.g.*
*have a race condition (don't use it if transaction is high)*
id_max = db.order.id.max()
maxID = db(db.order).select(id_max).first()[id_max]
order_id = int(maxID) + 1 if maxID else 1
The order table id will be returned by the insert statement. There will be
no race. We can use the returned id in items table.

face this before, usually created the form with web2py components 1 for
items (up first), save the value of items on the sessions then another
component for order table (below to submit all the data (data in sessions
input to items and order data)
during the form.process() or form.validate()
Thank Cliff and Massimo for your help.
I have finally make in very similar fission:
I have 2 divs,
controller1 with static form with id=1 that inserted in div1,
another controller2 that triggers by w2p_component (ajax) and generates
form with id=2 and inserted to div2 but all input fields of this
Here is what I do.
Your page should have one form only.
Make 2 divs. Top div has your fixed fields including the one that triggers the
variable content.
Use jquery to catch the change event for the field. When the field changes send
an Ajax request to the server.
Let the server build the
Thanks Massimo.
Here is my reformatted question(hope it will be more understandable):
I want to present two input sets of information coming from server into
two sections of the same view (div1 and div2). First input set is generated
based on user choice control, that presented at the
This helps but I still have some questions... where is form? what is
tab1? is this used the output of two generated SQLFORM? or the actual
source view?

Hi Massimo,
Here is my dilemma:
I have one view with 3 tabs (DIVS), where I would like to have one tab for user
tool selection and two forms in 2 separated tabs(DIVs) : 1)static form and
2)dynamic form(generated based on user selection in first tab). Also I would
like to submit all information
I believe your problem is the XY
problem. http://mywiki.wooledge.org/XyProblem
Y = submitting to forms to the same controller.
Do no ask about Y. What it your original problem X for which you think Y is
a good solution?

Or on different tabs.
In either case, update the fields on the tab or fold being closed to
avoid losing input.
You can use ajax for this.

in the controller logic, then, something like

should do the job.

I think you're going to have some trouble with this. Your best bet is
to go with SQLFORM.factory. problem is, you lose your nice CRUD
functionality. But it gives you complete control.
