Hi,
I'm currently learning Django and I've tried the autocomplete-light
framework base on Select2.
The problem i'm facing is that I want to Forward input field information to
filter another input field.
There is a lot of information about that on the internet and on the
autocomplete-light tutorial but, every example that I've seen use the same
url address to make there Foward. I was wondering if it was possible to
Forward it to another address ?
I can change the url adress but it make my first input field return element
of the second.
In the code below, want I want is to filter codePostalResidence base on the
selected villeMunicipaliteResidence value.
I want the form to filter base on the link "cmunic = munic_id"
I know that's a lot of information, but if someone can give me a hint about
anything it would really help me.
Thanks!
