Dear All ,
i want to build a form in html and when the form is accepted send its

can i catch it in the controler and see if its accepted , how can i
do that ??
How does choosing option 1 -- option 3 affect building a UI ?
It seems to me that option 1 can be used as-is in an SQLFORM.grid
containing other fields,
whereas option 3 might require a separate SQLFORM.grid to manage the
correspondence tags-items?
If this is just me not understanding all
Same as usual -- you have to create a FORM (or SQLFORM) object in the
controller and use form.accepts (or the newer form.process). You can create
the form manually in HTML and just make sure you include the _formname
hidden field
(see http://web2py.com/book/default/chapter/07#SQLFORM-in-HTML),

Again, if just focused on form validation, I suppose another option would be
to use an onvalidation function (processed after form validation but before
db insert).

Let me explain and clarify.
A grid can display multiple actions (select/edit/view/update etc...)

different URLs. This is a feature. This allows you to reference a

I have created some database tables externally to web2py. Does web2py

Surely there must be a solution to this? It does not seem logical to

iframe is not a good solution. And I don't think LOAD with ajax works
with multiple grids and pagination - certainly it does not work in my
application even after
also slightly frustrating is that the add/view/edit pass the table
name so you can generate output based on that. However the paginate
buttons do not pass the table name. So if you have a controller that
dynamically creates grid parameters depending on the table then this
does not work with

before_insert receives values that will be inserted on database. It

You can customize representation format, not stored format. It was
