Anthony, now I have written a small program as example :
def test1():
if "f" in request.vars:
raise HTTP(401, "f=%s" % str(request.vars.f))
form = SQLFORM.grid(db.tt,
selectable=lambda ids: None,
)
form.elements('table')[0].append(INPUT(_type='text', _name='f'))
return dict(form=form)
You are right - request.vars.f contains the value. But only if I do not use
the "selectable" values.
Now I change this program (like the example in chapter SQLFORM.grid in the
book):
def test1():
form = SQLFORM.grid(db.tt,
selectable=lambda ids: redirect(URL('test2', vars=dict(id=ids)))
)
form.elements('table')[0].append(INPUT(_type='text', _name='f'))
return dict(form=form)
def test2():
return dict(form=request.vars)
test2 shows the ids of the selected rows. But now the value of *f *is not
accessable.
What can I do to get both?
