Modelform and Ajax (Select a valid choice..... Error)

[siddharth ghumre]

Hi,

I am facing problem in handling modelform and ajax together.
The situation is:-
I am using modelform to get display the form as ul in the template.
I have 3 ChoiceFields (country, state,city). On select of a country
from the dropdown, the valid states dropdown gets populated and on
select of a state the respective city dropdown gets populated.
For achieving the above functionality I am calling an ajax function
which returns me the available data of the other dropdown in Json Form
{stat_id, stat_name}
I am able to populate the data in next dropdown i.e state and city,
but when i click submit form it shows "Select a valid choice. 8 is not
one of the available choices"
8 happens to be the stat_id in this case.
I have gone through google but dint find anything useful. Help is
really appreciated.

How are you populating the choices in the ChoiceField? Remember, you need to do this on BOTH the POST AND the non-POST versions of creating the form.

But ChoiceField is a Form field, not a Model field... so its not perfectly clear what you're asking.
