Chained combobox problem

[Mladen Uzelac]

hi,

I have a form with three comboxes that are chained. 

Models are chained via intermediary table.

model goes like this

class A(models.Model):

    id

    name

class B(models.Model):

    id

    name

class B(models.Model):

    id

    name

class Choice(models.Model):

   a = models.ForeignKey(A)

   b = models.ForeignKey(B)

   c = models.ForeignKey(C)

Choice is some combination of A,B,C that are related in some way.

This structure is required by the "Business model" .

I would like to:

1. choose value from A, filter B, 

2. choose value from B, filter C

3. choose C

And then take those values to further processing.

I did lookups for choosing those values in the form, but I don't know how to gradual filtering.

Kind regards, Mladen.

There is an example of doing this in the docs: http://django-selectable.readthedocs.org/en/v0.8.X/advanced.html#chained-selection What have you tried that isn't working?

I have succeeded what I wanted to. :D

A little playing with filters came handy.

Since I am novice in Django, at first I could not do what I wanted.
