[web2py] Passing variables from form to function to be classified and matched against DB

[Sam Flynn]

I'm trying to do a step process with data and having difficulty
figuring it out.  Any help MUCH appreciated!

I want to use a standard form such as input_form.html.  The input
values will be for values of w, x, y, z (e.g. W:
<input name="w" />).  From there I want to send the input values to
the following function to be classified:

class Scenario(object):
  def __init__(self, w, x, y, z):
    self.val = {}
    self.val['w'] = self.value(w,10,50)
    self.val['x'] = self.value(x,5,15)
    self.val['y'] = self.value(y,25,75)
    self.val['z'] = self.value(z,3,7)
  def value(self, v, l, u):
    if (v < l):
      return "low"
    if (u > v >= l ):
      return "med"
    if (v >= u):
      return "high"
  def __str__(self):
    return "scenario = (w: " + self.val['w'] + " x: " + self.val['x']
+ " y: " + self.val['y'] + " z: " + self.val['z'] + ")"

This will return a scenario = w: w, x: x, y: y, z: z.

I'm looking to then match that scenario value against a table of the
80 possible scenarios and retrieve an output for the matching scenario
in the table.  The output I would send back to the 'next' page from
the form along with a print of the scenario in question.

Again, any help on this greatly appreciated.  Once I see it once I'll
be able to get it.
