Django - Admin - on form change

Question

I have a general question to the django-admin.

Is it possible to react on form changes?

I have a select field in my django-admin detail site. Whenever i change the data from the select field, i want to change fields which are readonly.

Anybody ever dealed with this issue?

Answer 1

My two cents:

As any other guys said it is a javascript work. In admin pages Django pases jquery. It is called django.jQuery. So basilly you would do what @Ashfaq suggested. You will create a custom_script.js and added to the Media metaclass.

Basically(as @Ashfaq):

class MyModelAdmin(admin.ModelAdmin):
    class Media:
        js = ("js/custom_script.js",)

and custom_script.js will be something like this(assuming that your select field is called id_category):

django.jQuery( document ).ready(function() {
    console.log( "ready!" );
    django.jQuery('#id_category').change(function() {
      alert( "Handler for #id_category was called." );
    });
});

The ready function will guarantee the handler is getting set.

I think the thing that will work here is to add jQuery + your custom javascript and play with the events / clicks what-ever you want with elements.

class MyModelAdmin(admin.ModelAdmin):
    class Media:
        js = ("js/custom_script.js",)

in custom_script you can add click or change events as you want.
